demotorsport Posted April 9, 2008 Report Posted April 9, 2008 got a bad oil leak behiind the crank pulley and it sits on the silver part above sump behind pullet but i can't find where it comes from??? any ideas where it is coming from any1??? my guess is crank seal(front) or cam seal dripping down the back of plate behind the pulleys that bolts to block and ends up on bottom any1 had this leak before and what was it i have cleaned area and still can't find where it comes from cause the plastic cover is on top of the location of oil any1 thanks Quote
Sam_Q Posted April 9, 2008 Report Posted April 9, 2008 its very likely to be the crank seal, its cheap to change but a little tricky to do. To get to it you will need to remove your belts, crank pulley, timing belt drive pulley, belt end plate, etc... Quote

foc64 Posted April 9, 2008 Report Posted April 9, 2008 Could also be leaking from the rear of the oil pump to block area (current problem I have with my 4ac motor). As Sam Q said you need to remove all your belts, crank pully etc to get to this to replace the crank oil seal and you will have to do the same amount of work to fix the oil pump leak if this is what your problem is.

Trev Posted April 9, 2008 Report Posted April 9, 2008 I had an oil leak that covered the oil pump, Found that the cam seals were stuffed. Quote

They are available off the shelf in Kelpro or ACL, cheap as. Even if you can avoid it take the radiator out, makes life so much easier and no accidentle punctures Quote
demotorsport Posted April 9, 2008 Author Report Posted April 9, 2008 (edited) there the 3 things i thought it could be cam seal i do see oil on top of the inlet cam side between cam cover and backing plate crank seal(not sure how to check) oil pump seal(not sure how to check) is there anyway to check which 1 it is ?????? but i spose for all three things listed the backing plate belts etc all have to come off and if theres oil on back of the backing plate it would be the cam seal and I'm not sure how i will tell if its the crank seal or the pump seal cause there in same location arent they???

Your oil pump seal is your crank seal or were you talking about the gasket behind the pump? Quote
Sam_Q Posted April 9, 2008 Report Posted April 9, 2008 just change them both, should be a cheap enough. Or you could just do what everyone else does.. ignore it Quote
demotorsport Posted April 9, 2008 Author Report Posted April 9, 2008 (edited) just change them both, should be a cheap enough. Or you could just do what everyone else does.. ignore it lol...been ignoring it so far...lol... i was thinking there is a seal behind where the pump bolts up to block but can't say for sure cause havent had it off yet spose when its appart ill do all 3 i got the cam seals with the timming belt kit ill buy the other seals before i start ripping appart spose ill ignore it till after i get the car tunned for now and attack it after that providing its still allive...lol... just don't get how it leaks so much just sitting there without starting the car cause most of oil is in the sump leaks heeps now and haventy started it for over a week and i keep wipping it Edited April 10, 2008 by demotorsport Quote
