Front Of Gear Box Leak

[PhilGTR]

hey guys,

I recently noticed right at the front of my gear box where it connects to the engine there is an oil leak near one of the bolts. But its a very slow leak, like after a week in the garage there is a very small patch on the floor. Can someone tell me why it would be leaking there?? Does it need to be tightened more? or too much oil or is something broken? Just wanna know how urgent this will need to be fixed.

I have attached a pic of where it is leaking and circled it.

Thanks for the help

rear main engine seal.... You need to remove the flywheel to access it

Thanks, Any ideas on how much the labour would cost for a job like this? The seals im guessing wont cost too much?

It might be the rear main seal, but there appears to be oil staining on the sump further forward in that photo and it might be that the oil is just collecting at the lowest point. Before going to the trouble and expense of removing the gearbox, I suggest you _thoroughly_ degrease the entire area, run the car for a week or so and see if you can confirm where the leak is.

As suggested.. It could just be the sump pan bolts. I've tightened them on another car, and thats been enough to fix the leak. They often work loose over time.

If you're unfortunate, its the rear main seal, which means the whole gearbox (and flywheel) has to be taken off to replace the seal.

It seems to a common problem in older RB engines. My rb20 has had the same problem for quite a while.

Thanks guys,

Well my motor is coming out soon, so maybe I can see what the problem is then?

defently do a degrease and see exactly where it coming from from.

if you do have to change the seal, the oem ones cost about $80!! i went for an aftermarket which looked exactly the same and cost me $20.

no probs so far (touch wood)

Thanks can you let me know where you got your seal from for 20 bucks??

[PHATR32]

i got it from an auto parts store down the road. the dude also has a seal business and pretty much stocks any type of seal.

u in perth?

Nah im all the way across the country from you in Newcastle... DOh! no cheap seals for me. unless they deliver! Do they have a website?

[PHATR32]

nope, sorry

GRRRRRRR did'nt think of the rear main seal but that's prob what my prob is too. Looking at your pic, it's similar to my issue. It does'nt leak like a sive but when I push the car hard I notice a little puddle and it drips from the lowest point which would be the bell housing of the tranny.

Crap....NOW IM PISSED!

I will go through and check that all my bolts are tight but other then the head gasket or rear main seal there really is'nt any other place it could come from. Funny thing is my oil level has'nt really changed at all. :lol:

No, its not enough to notice a change in the oil for weeks/months.. but its just a bit messy.

Mines been like that for 12 months.. was like that ever since it came into the country.
