Subject: [TR] Timing case oil leak

From: Stuart Greenwood <[email-masked]>
Date: Tue, 23 Feb 2021 01:27:48 +0000 (UTC)

In July 2017 I saw that the front crankshaft oil seal was leaking on my TR250 but the timing case itself seemed to be leak free. In January 2018 I replaced this seal which of course meant removing the timing case cover and using a new gasket. I serviced the car last weekend and could see that the oil seal was not leaking but there seems to be oil leaking through the timing case gasket. 
I have the same situation on my Spitfire Mk IV. I completely rebuilt the engine in April 2004. Now, after about 15,000 miles since the rebuild  there are signs that the crankshaft oil seal is leaking again  and the timing cover gasket is leaking oil. 
I am starting to think that the gaskets you can buy are not oil leak proof. I think that over time oil seeps through the gasket material, NOT between the gasket and the engine block or between the gasket and the timing case cover but through the gasket material itself.
I am going to replace the oil seal on the Spitfire but the question I have for the list is should I use a gasket or use "form a gasket"  RTV type stuff? Have any of you used a gasket that is guaranteed not permeable to oil and if so where did you buy it from?

Has anyone else suspected that some gasket you can by from reputable dealers like TRF, Moss or Rimmers are in reality permeable to oil?

Stuart,

I=92ve taken to making my own gaskets. Buy a roll of Karropak gasket materi=
al (various thicknesses available) and a cheap set of hole punches. I=92ve =
never had one of my gaskets leak. All the thin paper transmission gaskets I=
 got in a set from a vendor, leaked.

YMMV.

Cliff

I agree with the statement "Hylomar is the answer".

Now, the next question is - which one? From Hylomar's website, I see about
13 products that probably could be used for gasket making/sealing. Also,
other than mail order to someone like Grainger, where do you find their
products locally?

I also had a deformation in the front engine plate which caused the timing chain cover to leak.  I used “Right Stuff” to seal the timing chain cover to the engine front plate. I’ve used Hylomar extensively, but the deformation required filling a deformation gap and “Right Stuff” excelled at that, sealing my timing chain cover perfectly. I have been told hat Right Stuff is a bear to remove, but so far I’ve had no need to to do that.
	Best,
