Druck Pressure??

[Nine9six]

Judging from this thread, SlantnoseSD is NOT a DIY kinda guy. I even sense questions as to which mouse button to click.
I would suggest finding a good honest independent P-mechanic and have him help you out.
Yeah, I know....

Whats the part #? How do you do that? Are they difficult to find? Do they do house calls? Do they leak oil? How much do they charge? Can I afford one?.........................

[SlantnoseSD]

Thansk for the words of encouragement but I'm not even sure why you took the time to post unless it was just to rag on me.

I am a DIY guy and I ask alot of questions to make sure I don't make mistakes. In fact, isn't this the "technical forum board" and isn't that the point of this board. If your going to make comments about people posting questions then why are you even here.

I just finished rebuilding the motor on my 1987 BMW M6 and since they dont make a manual for it I had to do it with the help of the BMW guys from the Roadfly forum. They were extremely helpful as are most people on this board...except Nine9six

If it stays up there when the ignition is off you may just want to tap on the glass a few times and see if the needle falls. Mine got stuck up there when the wire came disconnected...................a few taps released the needle and then it was just a matter of reconnecting the wire on the sensor.

[SlantnoseSD]

ok, i'll try that

[SlantnoseSD]

ok, So I pulled the gauge and tapped ont he glass and the needle dropped to zero.

As soon as I turned the key to ACC it went right back to the top again.

Any suggestions?

[74911targa]

Have you checked to make sure both wires are connected at the sensor? If they are, I would disconnect, clean and make sure you have a good connection.

[SlantnoseSD]

ok, that will be my next thing...thanks

Slantnose: You are asking some very basic questions; it's alright not to have any mechanical/electrical knowledge; it's a vast field.
I think what nine9six means is that you should not expect that other members on this board do the research for you, like parts numbers etc.
Get a Bentley, read, read.......
Learn how your multimeter works, read the instructions for it.
To give you "Electricity 101" on this post is too much to ask.
Yes, this board is extremely helpful but you need to do some ground-work. Get some books, learn the basics on how to use your meter;
It is either the sender, wires, or gauge; a simple problem.
There is even a electrical schematic in the Tech Section on PP.

I remember a post not too long ago where it took six pages to help someone with a fan belt issue. LOL.
Best wishes.

[SlantnoseSD]

Actually Gunter this board is to ask these types of questions exactly and if you dont want to help then you have the option of not responding.

This isn't like school where I have to go figure it out myself and then when I have exhasuted all other avenues, I am allowed to ask on the board.

I always try to help out everyone on answers to questiosn that I already know. I have never told anyone to go look it up.

I am coming from the BMW board where everyone seemed to help out no matter how simple the question but here it seems everybody gives you grief for asking simple questions.

I think this board should go by the policy that if you feel you are too good to answer simple questions, THEN DON'T

I'm experiencing a similar problem with my pressure sender/wiring. From what I've read, a pegged needle means that the problem is with something other than the gauge itself. Electrical is probably my weakest DIY subject, in particular diagnosing electrical problems and I would also like to hear how to use a multimeter to test the sender.

It's not a matter of how simple the questions are, it's a matter of courtesy for others who are willing to help you with their knowledge and time without expecting something in return. Shouldn't it be the responsibility of the one who's asking to do the best in his part as to minimize the work OTHERS have to do for ONESELF?

Not many people memorize the part numbers for all the major components, so it's not like they are refusing a simple task of remembering something and writing it out. Then, if it's a matter of opening a book and looking it up and not some very specific knowledge that comes only from working on these cars for many years, which it is, why can't one do it himself? Pelican uses factory part numbers in their catalogue as well.

Give a man a fish......

With the engine running, while being careful not to get caught by the fan, check the resistance between the connection on the oil pressure sender and the body/engine/a ground. It should read some reasonable number (which I can't remember but pretty sure a search will reveal), not infinite, nor 0. To check the wiring, ground either the gauge end or the sender end and check voltage between the wire end and a 12V source.

slantnose: Babbling on isn't going to help; You are missing the point.
Do you really think that other people should spend their time to provide you with info that you can dig up yourself?
I am helping you by suggesting that you get some reading material.
Read the instructions for your multimeter. Get a Bentley Repair Manual.
READ, READ and get some basic knowledge.
The oil pressure issue is a simple problem. There are many more much more complicated. If you don't have some basic skills, I suggest that you consider not doing anything.
Some people are not DIY's and sometimes do more harm than good.
Best wishes.

[SlantnoseSD]

Holy Crap people....its a friggin board for asking questions.....if you dont like it, then dont answer...and stop *****in' about people posting questions or this is going to be a real quiet and boring board!!!

Man, you all must be a bunch of old farts!

[74911targa]

I got started here 50 or some posts ago and I'm thankful for the folks who helped me out with answers to dumb questions that I've asked. I thought that is how this board gor started? Should we make a few different categorIEs for questions (IE .....stupid questions.......good questions........super smart, f-car suggestions) or should we just do are best to help out our fellow Porsche guy? c'mon now, let's have a little fun and be glad we are driving what we're driving...............I just hope that no one else will be afraid to join this board do to the reactions they think they might get......I know that if I was offended originally I wouldn't have come back. Yet I know that I am thankful for the help I've recIEved here and will do my best to help whoever has a problem that comes here in the future. Good luck with everything...............I'm sure nobody has anything better to complain about.

[randywebb]

you are all correct.

I agree with each of you.

[dentist90]

Let's find some middle ground... if possible. I'm sure 95% of the questions that pop up here have been covered before, but this forum would be pretty boring if it were just a search site for previously discussed topics. Hopefully we all remember our first few posts and the time it takes to become familiar with the 'protocol' of this BBS. Besides, periodic review of covered topics gives us something to do and helps fellow enthusiasts try things themselves.
This being said, Slantnose you should try to find out some of these basic things for yourself before firing a question back. Phil told you where the oil pressure sending unit is and what it looks like. Finding the part # is as easy as clicking over to the catalogue section of Pelican. If you can't find it, sure, ask someone. Maybe a more specific question about testing the sender unit wouldn't have rankled, ie 'does anyone know the resistance value for a working oil pressure sender' if a search doesn't yield the answer (and sorry, I don't know that either). No one wants to discourage anyone on this site, i'm sure. But it would look better if it appeared that you were attempting to make some progress on your own before asking your followup questions.
OK, I'm better now.

[SlantnoseSD]

Personally I really dont care if anyone thinks I'm looking it up on my own or just asking.....I stick by the theory of if you dont want to answer the question, whether its stupid, too easy, or you just dont care,...then dont answer it. I'm going to keep asking my questions and if you dont want to answer then dont and when no one wants to answer anyone elses questions on this board then it will just stop being a forum and we can all jump to other forums.

I have now wasted about as much time as I care to waste responding to the A-holes who felt like highjacking my thread to get on their soap box and preach to the rest of us about what questions are good and what questions aren't.

To the rest of you who helped me wiht my problem, I do really appreciate it and found most of the answers to be helpful. I am new to Porsches and questions will come up maybe they are easy, maybe they are stupid, maybe I'm just too lazy to look them up myself but thats what this forum and all forums are all about.

If anyone doesn't like it...too bad

[mike f]

There are many sites out there that can provide you with basic information on finding and repairing electrical problems. A quick google search turned up this page which should get you started. Good luck.

Did you ever find out the part number? I re-read the thread and surprisingly, it doesn't look like it's been answered yet. So here we go: 911 606 111 01.

The pressure sender unit is basically a potentiometer, and the gauge an analog ohmmeter. There must be a certain resistance through the sender and that number should change with the changing oil pressure, i.e. rpm. In order to test the sender, set the multimeter to measure resistance (R, ohms) and check the resistance between the "output" connection on top of the sender unit and any other ground point, i.e. the engine block or a bare metal like a screw head. If R ~ 0, resistance is futile, and there is a short circuit inside the sender unit that's causing the pegged needle. Replace the unit. If R is some odd big number like a couple thousands then the internal circuit is broken, replace the unit. I can measure mine (83SC which uses the same part number) if you want the specific range for R.

If all that checks out, then test the wires. First check all the connections, the connectors develop rust and such, or they come loose. That includes the output connection from the sender, and all the connection on the back of the gauge in dash. To test the continuity of the wire between the sender and the gauge, ground one end of the wire, and again using the multimeter in resistance readings, check the R between a known ground point and the non-grounded end of the wire. Since there is no other component in that ground-loop, the R here should be the resistance of the wire itself, which should be ~0 and neglectable. If resistance is futile, the wire's fine.

I'm not entirely sure how you'd test the gauge, I'll leave that up to someone who knows more. Now, it's been a long thread already but here's some more of my soap box speech...

As you might have noticed, Pelican board definitely has its own vibe; it may seem like hostility at first, but now I think it's more of a constant criticism among the majority of the members. Sure it is a technical board, but there are a lot of opinions about things that are anything but technical. All that "b!tching" is what makes this board not as boring as some other "technical" forums. Every single member here is unique with all kinds of personalities, different knowledge level and method of approaching problems and yet, because of this single common denominator that is the passion about Porsche cars, we brought ourselves into this giant community. That creates an opportunity to observe how different people has vastly differing views, and, naturally, conflicts arise when one steps beyond simple observation and offers one's opinion. What we have here regarding what questions to ask is one of them.

A few others and I have said it before, it's not a matter of a question being smart or dumb. Slantnose, I would like to hear your thoughts: do you truly think not putting in basic efforts to resolve your own problem when you're fully capable of doing so is the "right" way and you can justify it with "don't answer it if you don't like it"? It may be the right way for you, it most likely will work, since there are some very nice people around here who are willing to browse this website to find you some combination of numbers. Please tell me if you're not capable of it, for I must apologise for my insults in such case. Otherwise, I would say you're relying too much on the goodness of humanity. Guess what? That goodness wears out when more and more people expect you to do the same, simple tasks for them because they're too lazy and you are the "nice" guy. You can already see it happening here on this very forum; it starts with someone saying "hate to say this but do the search" and from then on, every response by that person regarding the subject would always be "do the search". I haven't been around very long but I've already seen that trend in quite a few people. Of course, a few people in this whole forum isn't gonna make a world of difference, but, no matter how minute it is, it's degenerating the society that's largely relying on the "nice" people willingly doing "good". If I were given a choice of improving or degenerating this forum and it all came down to little things I do on my end, it would be a no-brainer.

I realize, Slantnose, you would be the "nice" guy should another "stupid" question come up. That's really good for you, and good for us. But the problem is that not everybody works on that principle. Do you see how no one else has answered your simple part number question yet? Perhaps things don't work like they do in the BMW forum, not because of the difference between Porsche and BMW but solely because they're two different forums and the demographic is different.

I think I have said enough. I do not want to discourage nor do I intent to drive people away from this board. I just want to hear what you think. Like 74911targa said, around 100 posts seems to be the point where you find out if you can stay in this forum with people like me running around. Good luck with your problems.

PS. What is with all these negative, hijacking posts from Canadian "old farts" ?

[KCPSG]

Very well said.
