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.=20
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=C2=A0 t=
here are signs that the crankshaft oil seal is leaking again=C2=A0 and the =
timing cover gasket is leaking oil.=20
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"=C2=A0 RTV type=
stuff? Have any of you used a gasket that is guaranteed not permeable to o=
il and 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?
