Hi all, right had this leak for a long time now. It`s evident on the bottom of the crank in front of the sump but behind the pulley, i`m guessing this is just where it drains too.

So far i`ve had replaced all cam shaft seals, crank seal, rocker covers have been resealed along with the 120k service pack.

Pulling the belt cover back, i can see the pulleys have oil on them so obviously the belt too..great. So am i right in suspecting that unless the cams are scored the pulleys themselves are the likely culprits.

If so do they have o rings or do they just wear internally?

Cheers in advance.

turbo oil feed maybe

No, there`s no feed at cambelt end fella and have replaced those particular gaskets as found one was missing. Thanks though.

Remove cam covers and fire engine up, hold a sheet of paper in turn just above each pulley, if either pulley is leaking then a fine mist of oil will spray onto the paper. In my case i just got a known good second hand pulley from zedworld as they big bucks new.

Company in the US called BGT i think do refurbished pullies with a different spring in the back.

Cheers Smithy, you`re right they`re not cheap are they!

Do you know if the cam belt covers come off without removing anything or do the waterpipes have to be removed?

Sadly you gotta remove the water pipes mate, a pain in the arse i know especially if that area has been open numerous times before, but, it's the only sure fire way of knowing which pulley is at fault.

 

Oh you could leave the water pipes on and cut the covers off and then just one day fit another pair of newly painted ones. second hand about 20 bucks!

OOH cutting seems very tempting as i`m losing motivation on this thing..so near yet so far. Pretty much all the hassle i`ve had with this car is from other people doing a bad job, at least this may be just wear n tear. Wish i was rich then i`d just hand it all over to Jeff or Jimmer. Still onwards n upwards. I` ll be able to open my own garage after this lot..seem to have taken pretty much everything else apart and put right!

Cheers for your help mate.

Well i`ve removed the covers and put it all back together minus covers. The cam pulleys and belt are dry..hurrah. Have only managed tickover at mo and no oil but will get the vvt to prime the cams n see what happens.

There was definately remenants of oil behind the back plate on the cam shafts..how old it is i couldn`t say, the bottom of the plate also is glistening on the rear. i couldn`t remove one of the little bottom cover bolts as it`s been burred over.grrr.so i don`t know what it looks like behind that. So i`ve cleaned up what i can with solvent and we`ll see what happens. Now do i give it some beans to get the oil to vacate the pulley(S) or would they just leak on tick over?

I just had the engine on idle, then with 1 hand reved the throttle slightly and the other holding some paper.

 

Give it a few days and see what happens mate to be certain.

Well i`ve managed to remove the air con compressor as the pulleys are not squirting anything, it would appear to be coming from behind the cas area. So, i`m` aware the cas unit does have a seal of sorts as i have a new unit here. Has anybody seen a leak here before?
