'79 911 turbo

[rkh3]

New owner and have a couple questions. Compared to a "non-turbo" engine, what regular service items are distinct to the turbo?

I checked the oil level with the dip stick (in the filler nozzle) and it barely registers (when warm & not running), but the pressure gauge reads OK as well as the oil level gauge???

I'll have more questions! Thanks for your help!

1. There are no turbo-specific regular service items.

2. Your manual states that you should have your engine running when checking oil-level, so why are you checking it with engine off?

[rkh3]

Because I don't have a manual..............

Well now you know...all 911 engines prior to 996C2 and Boxter are dry-sumped and oil-level should be checked with engine running. Overfilling oil beacuse of bad level-checking usually leads to excessive smoke and in worst case, blown seals. Search on "overfilled oil" and you will find out that there are many people who did same mistake. Welcome to Pelican by the way...

Tell us about your car. Any mods? Pictures?

I checked the dip stick level when warm and running, it was dry. I added 3 qts, stopping between each to check level. Now it is slightly above MIN, but the oil level gauge dropped to the top margin of the red zone at the bottom of the gauge, but it is not in the red zone. I'm a little confused, I would think that as you add oil the indicator would go UP not down.

Sorry if i sounded rude, i just believed everybody knew to check the level with engine on.

About oil-level, i say don't trust the indicator, trust the stick. Also, my expirience is that 930 usually runs best when there is just enough oil, with other words, just a bit over "MIN" line...

I believe your indicator is a bit rusty (not oiled enough?) so it's not indicating right.

Welcome to the board!

Show us your 930!

My mechanic keeps telling me the same thing. He's a firm believer in that theory and it seems to suit my cars just fine.

Another question- Would low (3qts) cause "stumbling". I may be sorry to say, I picked up the car last Friday night and it ran fine, except "popping" through the exhaust on decelleration, thought that odd but maybe normal. I drove it a couple hundred miles over the week end-all fine but still "popped". Filled the gas tank late yesterday (another possible cause i.e. bad gas?) and drove it 50 more miles-fine. Today if you hold a speed it stumbles though it accelerates fine. By the way it is fuel injected. There is a slight "tap" coming from the engine, only when warm

Excuse my ignorance, but I have been into muscle cars for years, it is probably obvious, but this is my first Porsche.

Thanks

My mechanic says the same thing also. He tells me to fill it with just 10 quarts for an oil change.

I'm sure you noticed immedeatly, this is a conversion. It was born a 911SC.

That's the car that has been on eBay several times in the last year. It looks nice.

I also agree with this opinion.

When the engine gets hot enough at the right RPMs you can see from the cabin guage that this set up will occasionally surge to the top level.

The low setting gives you enough saftey margin so oil won't come puking out of your tank breather and really give you a scare something is wrong.

With almost 15 quarts in the system you have little to fear about the min setting not being enough oil.

It was sold out of CA in May on EBay (can't find it though), the guy, from receipts-etc, in CA put a ton of $$ into it

Not sure whats up, I clicked it (on the post) & it worked.

Don't trust the gauge in the dash. Trust the dipstick, and make sure the car is warmed up (meaning: 15 minutes or so of driving) before you trust the level on the dipstick. It should be idling on a level surface.

I can't imagine why being 3 quarts low on oil would cause any problems at all, unless you were winding it out like you were on a race track.

You've found a great resource for the car in this board. As MJ said, there are no stupid questions.

[rkh3]

Any insight into the "popping" through the exhaust on decel?

[Adam]

Possibly an exhaust leak?
