Mysterious SBC Oil leak
Discussion
I'm fortunate in so much as I have a pitt in my current garage (that I've used every week since I bought the car!). It makes doing the sump so much easier. I've already done the job once (the sump pan seal was gone), so the most inconvenient part is having to jack the block off the chassis to get clearance for the pan to clear the chassis.......
I've seen the one piece seals but have been advised away from them by both the pan manufacturer (stefs) and the engine builder.
All in all Just one of those jobs that isn't fun - tea in an almost endless supply

hahaha you be careful mate
it is nice but ambiant temp too cold to get any heat into the tyres and it will spin everywhere..
if you are going on Sunday on the scd run be very very careful.
mines tucked away now until end of march as no fun in this weather unless you are good with bodywork

An hour's fun can lead to many hours spent having no fun at all!!!!!

Be sure to check the diameter of seal housing too .
Some remanufactured blocks and most aftermarket (dart in particular) have an oversize OD seal bore and the appropriate seal should be fitted ... A std seal can be fitted but has to be bonded in and usually fails prematurely .... Better to get the correct one .
G luck ..

Will do and thanks. The block is a GM aluminium 'performance' unit - so I'd like to think that the dimensions should be on spec !
The engine builder should be back to work today so I can his advise on which seal I should be using..... Coincides nicely with the fact that the sump is off - just needs extracting from the chassis.

So patience being a virtue - having left the sump for about a week to drain - the removal was (fairly) straightforward, especially as I've had a fair bit of practice. Absolutely ZERO evidence that the sump gasket was leaking (which is reassuring as I only did that a couple of months ago ) BUT the flywheel is suspiciously dry........
I talked with the (ever helpful) Tim at Peter Knight Racing and ordered the rear main seal (Fel-Pro 2909), once he confirmed what it was. So the only issue that I have is the last two torx bolt holding the end cap on - any ideas? It's slightly larger than a T50..... I had no idea that imperial TORX existed.

So Pete (the engine builder) is going to send me a fitting that should do the business. He did also suggest another source for the oil leaks - it could be coming from the oil inspection galleries. Behind the gearbox adaptor....... Either way, the main seal would be the correct 1st fix and we'll see how we go from here on in.
Fingers crossed!
