EJs and rear main seals
pete wood - May 20th, 2006 at 10:16 PM

Has anyone had issues with their rear main seals? I think I'm about to replace mine again after only 5000 kays or so.

Do ej25 DOHC motors have issues with them?

maybe you didn't put the last one in properly?

I made a cup type tool to install mine .

make sure the crank area is not worn

I didn't put the last one in my VW mechanic did. I trust him with my life as far as cars go.

how do I check if the crank is worn?

and if it is, what do I do about it?

Just make sure the single lip seal has the helical on it and not just a plain lip. Check for crank lift at the rear main bearing.

are you sure its coming from the main seal ?

Make sure its not coming out the cover plate on the rear of the motor behind the fly wheel .

The motor knows it is in a Volkswagen and 'has' to leak oil :lol:

No, I'll check that too when I pull it out. It can stay where it is for now though I think. I've got a khanacross coming up in a month, so I'll pull it after that.

Ej motors have the odd rear main leak like 1 in a 1000 when u do the rear main pull the gaugin pin cover plate off and reseal it with three bond anyway and possibly look at the O ring under the cover plate on the otherside. Dont wanna pull the engine out twice :)

Thanx for the tips boys. Had a decent look yesterday and there no oil on the back of the motor when you look up the hatch between the engine and gearbox. So it's not the rear main. HORAY! Must be coming from the rocker covers (and the gearbox is leaking a little too). This is the second or third time I've had to stop the rocker covers leaking. Any tips on this?
