Oil Leak

[SECURITY]

When i rebuilt my motor, i used an N1 oil pump on my rb25 crank.

i was told by alot of people that it would go straight on without any need for a collar.

the leak is coming from around the front left hand side of the motor, there is no oil on the HB, but there on the power steering pulley. the leak comes out in little drops too.

is there any other place it coud be coming from?

with diagnosising oil leaks always start at the top. check the rocker cover, remove the timing case and check where the rocker cover meets the black timing belt backing plate. with it off you can check your cam seals, then start working down towards the crank seal. generally thou with crank seals there will be a fair share of oil sparayed all over the front of the engine. dont forget to check the vct unit on the intake cam but i couldnt see this leaking throu the timing case and over the p.s pump.

other options include blocking off all your breathers etc and putting about 5-6psi of compressed air into the motor to carry out an oil leak test.

good luck. oil leaks suck...............

just ensure that it is engine oil that u are chasing not old, blackened p/s oil that has never been changed!

The dimensions of the seal required is 40 X 52 X 7

This seal is used for ALL RB30's/25's/26's and 20's

i found an oil leak from my head, the stud was missing and there was oil leaking through the exhaust manifold hole down the side of the engine and around the sump..

thanks for that guys, i was worried i'd need to pull the pump off.

its not leaking from the power steering pump, the leak drips onto the ground from the power steering pulley. the oil coming out is clean engine oil.

can you explain this one for me mate?

well, i broke the first top stud in the head, had to get it drilled out and a bodgy mechanic ended up drilling through the head.. didnt realise this, until i had an oil leak problem, and had no idea where it was coming from until i followed the trace of oil to the spot.. so i had to get the hole rethreaded and sealed, then i fit a slightly larger stud in its place..

not saying you got the same problem, but im just saying to check everywhere, including around the head..

thanks man, i doubt its a broken stud. im pretty sure its coming from the left hand side. i saw oil on the vct return, so its probably from around there if not there, ill have a look tomorrow.

thanks again.
