Engine Compartment Seal?

[Kool-aid-82]

I have been Cleaning, Fixing and Replacing issues in preparation to putting the engine back in my 81 911.

My old engine compartment seal was 30 years of hard brittleness so I removed it and discarded it months ago and ordered a new one from our host.

Today I started putting the new one in and noticed a section has the lower seal cut out.
Can anyone else verify if this is this normal?


Also when the motor goes back in does the seal go?
1 - on top of tin
2 - below tin
3 - split (both above and below tin)

My old one was only on top... I think

New seal pic,


Thanks,

Why don't you take a look at the detailed pictures you took of everything before you disassembled it?

From what I recall, all the seals sit on top of the tin, nothing below; the idea is to create an air tight space to be able to cook the engine more efficiently. I've not done mine but it's on the list of to-do's when I rebuild my top end.

I have always placed the tin between the two seals, a real PITA ut I gradually raise the engine as I hand fit the seals between the tin's edge

on my 83SC - no cuts in the seal.
One part goes above the tin, the other below the tin.

Pretty certain tin goes between both parts.

The missing part on the bottom of mine lines up nicely with my turbo. There is so much heat there, it wouldn't last long.

Could it be there is a turbo and a non-turbo version?

[DRACO A5OG]

Hmmm? I have a cut out section too. I thought it broke off but will need to take a closer look since engine is out too.

[Kool-aid-82]

Thanks guys. (Detailed pictures, what is that?)

Looks like there is a separate late model 930 seal but this is what was ordered and received.



Fits both turbo and non turbo so I am going to leave it and run it.

FWIW - I slid the front in - (PITA)
On the rear seal I saw no way to make the corners doing this. so i put in the top lip and used a dull tool to pop the bottom half in the grove, much easier.

Still researching the engine tin to seal but I can tell from the wear marks on the my tin that the seal was only on top. I just can't see the German Engineers designing this to be split in engine install.

[Kool-aid-82]

While my seal was only above the tin I would say the engine tin goes between the seals.

After installing the engine but before fighting the engine & trans mount bolts I uses a screwdriver to slide around the tin and pull out the bottom seal.

(Looks right)



No way to do this with my old crusty seal...

But the engines in and running.


And way Cooler, Thanks for the advice to everyone who chimed in.

I can confirm the rubber seals splits between the tin top and bottom and the front seal near the engine fan is a single piece

Mine was sitting on top of the tin, just had it fixed to fit in between.

I hoping that it might resolve the tinny clatter on load but can’t imagine it would as the tin sits comfortably away from the chassis

I'm just at this point in my re-install, so this was helpful! There was no 'cut' in the seals I ordered, so maybe there are two versions.

Put a cord between the seal lips and raise the engine up but not quite all the way - then pull the cord down to set the bottom lip below the tin. Then raise the engine into place- way easier than the screwdriver method

One flap above tin, the other below. Check out Kurt's video at the 8:20 mark

This is a great idea and I love it, will remember for next time.
