![]() ![]() I never saw any oil on the back of my flywheel. It leaked oil so when I did the lead-free petrol conversion 43,000 miles later, I took the crankshaft out, had it ground and put in a new modern rear main bearing seal. When I restored my 1958 TR3A from 1987 to 1990, I put in new seals for the rear bearing as per the original design. If possible caulk these also when you re-install them.Īs for oil or no oil on the back side of the flywheel, I suggest that there will never be any oil on the back of the flywheel because the centifugal force will spin it off. ![]() Make sure they are tight or they will leak oil. 1958 TRIUMPH TR3A ENGINE OIL GENERATORUp front there is at least one of the bolts holding the generator bracket to the block that is drilled and tapped right into an oil passage. I suggest you take it out, clean it up and use silicone caulking to seal it all back into place. This was done at the factory to keep it from falling out. The breather pipe which comes out near the petrol pump has two slots cut in it with a hack-saw. Good luck and let us know what the solution was. It could simply be blowing back when driving from say a leaking filter head/oil filter (you didn't say whether you were using your 3A?) or other simple to fix area(s) such as a new felt seal on the dipstick, or even just a loose oil breather pipe – are the stay brackets fitted?Īlso check it is not dripping down from the rear of the rocker cover due to a leaking gasket. If it is the crankseal, this is more time consuming but I believe you do not need to take out the engine but can just drop the sump and crankshaft - Argos (aka Moss) do an uprated crankseal (TT1032/S) and one is fitted to TRK without problemsīut before going down either of these routes I would advise checking the easy to see/fix things first. If the latter, it's a simple job but you have to whip out the gearbox and remove the flywheel to replace the plate but you will have to do this to inspect the crankseal anywayģ. If there is oil on the flywheel, it could be one of two things firstly the crankseal as you suspect or secondly the camshaft core plug (it was this little bugger on TRK recently). Remove the thin clutch cover plate on the underside of the bellhousing and look to see if the flywheel is covered in oil you could also remove the starter motor to be doubly sure, but that’s real pain in the arse!Ģ. It's easy to check whether it is leaking from the rear of the block e.g. from talking to various people it seems it may be the rear crank seal? ![]()
