<DIV>On my last rebuild I used a product called “The Right Stuff” and it is. No
leaks from the likely spots. A bit pricy but worth it in my opinion. Comes in
gray and black. Used it on the OD adapter plate which has always leaked and now
only an occasional drop. I like it. I used it with an appropriate gasket.</DIV>

<DIV>These <FONT size=3>covers are stamped steel and can warp if the bolts are

<DIV dir=ltr>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. <BR></DIV>
<DIV dir=ltr>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. <BR></DIV>
<DIV dir=ltr>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.<BR></DIV>
<DIV dir=ltr>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?<BR></DIV>
<DIV dir=ltr> </DIV>
<DIV dir=ltr>Has anyone else suspected that some gasket you can by from
reputable dealers like TRF, Moss or Rimmers are in reality permeable to
oil?<BR></DIV>
