View Full Version : 1.8T Front Crank Oil Seal Housing

06-07-2011, 01:19 AM
I've started building my motor up, and i installed this oil seal housing with RTV silicone.

I've since noticed that its supposed to actually have a gasket on it.

Has anyone successfully used RTV here? Or should i pull it back off and fit the correct audi gasket?

i used a gasket and rtv.. i have heard of people having problems with it leaking with just the gasket.. i would take it out and replace the gasket then use rtv for the extra 'insurance'.. but who knows.. u might get away with it as long as u did a good job and the seal itself is in good condition..

You should definitely use a gasket on the front crank shaft seal. When you install the gasket you should not operate it for 4 hours to allow the seal to form around the crank shaft.

We have them available below.

Jason its not that seal i'm talking about, i've already replaced that with a new reinz seal.

Its one of the "U" shaped paper gaskets in this image that i have missed out:


I've gone and ordered them from the dealer today, was ordering some other parts anyway.

Cheers folks!

Ohh that gasket, I was thrown off a little by the title of the thread. I've heard mixed opinions on that. Some people just use RTV, others just the gasket, or a Combo of both. Not sure which way works the best, but if it were me I'd go with the combo of RTV and the gasket.

Reviving this thread... sorry...

I have rebuilt my 1.8t ATW - and it's leaking oil somewhere from the front of the motor.
I have already replaced all 3 front seal (cam, intermediate shaft, and crank) - but the engine still leaks.
Seems the only thing left (it's the head the gasket :-)) is that U-shape gasket behind the front crankshaft seal housing - the gasket mentioned here.
So I'm curious - what stopped your leak?
- gasket
- or both
I know mine was a dry gasket (no RTV) when I took it apart - but maybe that was "factory luck" :-)
Thanks for the help.
