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

Subject: [TR] Timing case oil leak
In July 2017 I saw that the front crankshaft oil seal was leaking on my TR2=
50 but the timing case itself seemed to be leak free. In January 2018 I rep=
laced this seal which of course meant removing the timing case cover and us=
ing a new gasket. I serviced the car last weekend and could see that the oi=
l 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 en=
gine 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 cov=
er 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 c=
over 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 stuf=
f? Have any of you used a gasket that is guaranteed not permeable to oil an=
d if so where did you buy it from?
Has anyone else suspected that some gasket you can by from reputable dealer=
s like TRF, Moss or Rimmers are in reality permeable to oil?
