71 911engine case crack help
 

Working on a 71 looking for an oil leak at rear of motor. Put two bottles of dye in the oil and ran, found a crack in the case above the freeze plug at the end of the oil galley top of motor behind the fan housing. Tried JB weld but looks like still coming out.
Does anyone have a different solution than JB weld? We might be able to sleeve the area at last resort. Any help would be appreciated.

Pictures might help.
Is the engine a T, E or S matching numbers to the chassis.
If not you might consider just replacing it. 2.2 cases can be pretty cheap to source. I thing I have a few.

Small point...there is no such thing as a freeze plug...sorry.
They are core plugs...and if inserted correctly...they do not come out until 10 seconds after the case has cracked.
Just one of the things that bugs me...once again..sorry for the rant.
Bob

Rants are okay, maybe a welch plug. At any rate Henry, I"ll take some pics later today. I think we may have on available on utube.
This is a 71 T just purchased by an F18 pilot from the family of the original owner, numbers matching. 72K miles.

I look forward to the pictures but I think I have a blank 3R case that you could number if all else fails.

Keep trying to learn new technology, which is about 15 years old by now.

That leak is something I haven't seen before.

Remove the plug (drill,tap and slide hammer), grind and weld the case. Replace the plug with a slightly large one.
If you have trouble finding the magnesium rod, let me know. I have a stick or two I can send you.
Cheers

Rusty,

I will toss out a hunch, the factory plug was removed at some point a one was fabricated to replace it. The fabricated plug is likely solid and when driven home split the boss. Just a hunch.

That would be dishonest......

Scott

In actuality, if you own the case you own the number. Porsche dealers did this quite often back in the day. If it was common practice back in the day, it might be impossible to detect. Restoring the proper number is not dishonest. A lack of disclosure to a third party may very well be.

Henry,

The whole point of a "numbers matching car" is that the car has the original engine. If you stamp a case with the original engine number, that is deceitful. This guy is fixing a '71 911 and wants to keep the matching engine if he can because it makes the car more valuable. Did blank cases get stamped with the original number back in the day? I guess. But doing so today on a classic numbers matching 911 would be for one reason only: deceit.

Scott

Henry,

Frankly, I am surprised you would suggest such a thing. This statement is scary from a guy that might do engine work on older "numbers matching" cars:

"If it was common practice back in the day, it might be impossible to detect. Restoring the proper number is not dishonest. A lack of disclosure to a third party may very well be."

That "may" in the last sentence is particular disturbing and disappointing....

Scott

As far as I am concened, I would be more concerned about having an engine properly rebuilt or not, rather than having engine numbers properly matching or not...of course having both is the ideal situation, but if the case is cracked...

We have her apart again, it appears that the leak initiated as a result of the JB not adhering to the welch plug. We will give her one more try and allow for additional curing time prior to firing her up.
Will keep you guys posted. Trying to stay focused on the issue at hand, not so much numbers matching at this time.
I have a 356B with a worn out matching numbers case which I keep on the shelf and running a nice 912 engine in the car. The case will go with the car if sold.
Appreciate the help on this one. Don't really want to pull the engine apart at this time.
The owner is looking for a set of deep sixes. I have two very nice ones if someone has just two they want to move.

Wow, thanks for the judgement.
Just so I'm clear, how much of the engine must be original for you [oh keep of what's right] to consider it original. Does piston replacement negate the "original " status?
When the factory restored Seinfeld's "first 911" with a new case with the original number was that deceitful?

!
 

Hear Hear !

numbers matching? who really cares, it is a repair of a part, if you must, sell the bad case with the car.

Henry,

Now I know where you draw the line.......what they don't know won't hurt them, right?

Scott

The truth is: you know less than nothing about me and I find your accusations offensive.

The internet is a interesting place where an absolute zero (that's you Scott) can challenge my integrity by simply distorting what is said.

I come here to offer options and you come here to cast aspersions. Why all the spite?

look at for sale adds that state numbers matching engine/trans/frame then look at what they did to maintain it. Most every part is listed as being replaced (crank, pistons, cylinders, cams, valves, heads, fan, ignition, induction system, etc) BUT the case is the same. numbers matching? sure. original? no way. It would never bother me having another engine in my car as long as i know it is properly repaired/modified. Keep going Henry

Henry,

I said that buying a blank case for a '71 911 and stamping the original engine number on it would be dishonest. Why? There is no reason to stamp the case. That could only lead to deceit.

You said that stamping a blank case with originals numbers was not dishonest. You also said that not disclosing the fact the case was not original "may" be dishonest.

Where did I distort what you wrote?

Scott

First, the reason to stamp a blank case with a number is to prevent possible impound do to lack of a serial number. In California, having a case with no number is generally construed by law enforcement as an altered case. It's not uncommon for a car (Porsche especially) to be impounded for altered numbers.
In order to prevent this false conclusion a case should be numbered. If you're going to number a case, what number would you recommend? I would recommend the number you own. Pretty simple, no deceit involved.
I rarely speak in absolutes so when I said "may" I was taking into consideration that deceit requires knowledge.
Your dad replaces the case and replace the original number. He dies leaving the car to your mom. She sells it as a matching numbers car. intent to deceive does not exist. In fact there is no intention to deceive on any level.
Perhaps you should save your self righteous blather and accusation for your ethics 101 class. The real world is not as black and white.

Damn, you left coasters sure get going. Henry, I personally thank you for taking the time to respond to my issue. One could always do as the factory and stamp a KD or AT in front of or behind he new number or some other identifier as a replacement case.
Have a great weekend and enjoy your ride.

In California, cops have shown up to car repair shops and check the VIN on the replacement parts. All parts that are stolen (VIN reported) are confiscated. Does not happen all the time, but they can do it.

For everyone reading the thread: apologize for getting upset but I struggle with the suggestion that my integrity is in question.


In the past I might have "called you out" but on the internet all I can do is "bust a Caps lock in your ass". :)

Nothing with Henry surprises me anymore. I own an original picasso and I can get a print of the same. Now I sign his name. Now I have to picasso's. Profit!

Unreal.

Since you own the original, does that give you license to sign all the copies and pass them off as original?

Imagine them showing up to a shop and finding two identically numbered cases. That would be a real head scratcher. Is it live, or is it Memorex?

Your self-perceived position over Scott does not absolve you of public scrutiny or judgement when you disclose practices that have an intention of deception or forgery. A verbal disclosure of the forgery will not make it defensible...

I suggest you do some reading big guy.

Illegal under California Law.

Is this some kind of veiled threat, Henry?

Check in with the "restoration" community to see what they think of your casual suggestion to use a blank case and stamp the original numbers into it. It won't go over well.

Anyone that cares to see what happens when you do this, read here:

How many engines have you built with a blank case and stamped the case with the original number? Did any of these engines go into a "numbers matching" cars? Was that disclosed to any buyers?

Scott

As an adviser to OCAT during the 90s, I am very well aware of the law. The concern of OCAT officers was documentation and intent. Receiving stolen property is a "specific intent" crime. Documentation generally negates intent.

In the 80s when I worked at the dealer, there was a plethora of 3.2 cases that had porosity oil leaks. The factory authorized a replacement case. The norm was to replace the case and install the original number.
The leaking case was returned to the factory for inspection and assumed destroyed.
The only thing that was replace was gaskets, seals and case.
Without a number

This was not my policy, it was Porsche factory.

This is not about what the Porsche dealers did in the '80's. This is about a '71 911 and you suggesting they use a new case and stamp it with the original number.

This is why it is bad to do what you suggest. If you can't see that, well, I don't know what to say....

Scott

Are you friggen kidding? It's an apology and I guess a veiled joke? I guess you missed the happy face as well as the point.

In fact, zero. That's not my job. Have I seen it done? yes : It was SOP at the dealer.

Do you see how stamping a blank engine case going into a 42 year old car with the original engine case number is not a good idea?

Scott

I see how making judgements about how other people live is not my job as well.
By bye sir.

The problem is that you are the one that suggested it!!!!!!

Rusty 356 makes a point of saying the car is "numbers matching". You make a point of saying you have a blank 3R case he could stamp with the original number.

To what end? To keep it "numbers matching"....

This is what I have a problem with and I am not alone. Dance around it all you want. Get all upset about your integrity being challenged. All I know if you are the one that made the suggestion.

Your ego won't let you say it was not the best idea you have come up with so you defend the suggestion. Sad....

Scott

"If all else fails" suggests that this is an option but not first or the best.

I think our problem lies in "to what end" and you assume the end is deceit. I in fact do not think that is the only reason.

I seem to remember a case of 2 904's being the same number.
Spain? or something like that?
The factory had replaced the frame with another one...and the original (withthe serial number) had been built into another car.
And this all came to light decades later.
Oh...what fun.
Bob

But first you say:

Your intention is to deceive law enforcement here. Great idea if you want to get acquainted with cell mate Bubba for some play time.

The difference is makers mark applied by the maker (dealership/factory). By applying the makers mark as an independent you are committing a forgery. This is a felony.
