Thread: Leaky 2 1/4 (Advise on Rear Main) also 32/36 performance.

MMMM ive rebuilt a 2 1/4 litre and when i did the rear main seal i did the t gaskets as well makes me wonder if that was your problem all a long

those t gaskets need special tools to replace them but dont stress you can easily make them out of angle iron

Can they be done by removing the sump and the rear main bearing cap?
Or do I have to remove the gearbox again ?

that im not shaw cause i did mine with the motor out of the car you might have to take the sump off to see i think the fly wheel could be in the way

but you never know your luck id also be carefull where you source you seal try and get original

hmmmmmm,rear main seals,me shudders with memories,oh what fun that was,NOT!!!!!!!
first attempt with g/box out,seal supplied was in two,yes two halves,when enquiries where made ,was told "thats how they come",so fitted it(against my better judgement ,but had to slow the rust prevention program for rwc ! ) and after much $#@^%@^$#@!^$#@ got the g/box back in.
After start up and a drive into the rwc place ,drip,drip,drip,so drove it home ,this time after another call to parts supplier(original parts too i mite add!)it was agreed that just maybe it was a suspect part and they would send me another one,UGH,not taking that &%$#&$#*g/box out again,so motor came out,new seal AND "T"seals went in and hey presto, no leaks,(took about three days to get that%$*$*&%$motor to line up again)

to answer your question , yes the sump will have to come off,if you can get enough room to do it in vehicle ,go for it ,otherwise is better to remove it and use either an engine stand or workshop floor,and use some feeler guages to protect the t seals when replacing the main bearing cap

have fun

G'day Michael2
Are you sure it is Engine Oil :?: as an over filling G/box will pump the oil up the primary shaft into the clutch housing and it will drip out of the wading plug hole I have a 2a that pumps oil from the Transfer case into the G/box and when that overfills it pumps it up the Primary shaft :x it might be worth checking the G/box & if it is over full drain some out and put it in the Transfer case as that is where it came from :wink:

Yeah, I've checked and it's engine oil.

I know you're talking about internal leaks, but as an aside, since using STAG Paste [a food grade sealant available at auto shops] as a sealant on the gearbox, it hasn't developed any external leaks.
