Hi lads i have a bit of a problem, me stupid engine is leaking and i dont know wat it could be, its had a head skim and block skim and brand new athena head gasket and its still leaking oil from between the head and block left hand side just above the oil filter housing, i dont know what it could be and iw mad to fix it so i can get driving it, needless to say its all newly forged and hasnt even been driven yet. Started it up and leaked oil so i turned it off took pictures and stripd it. It was torqued to the ARP settings, Please help. :(

Are you sure of the exact location of the leak? Could oil be coming out of the breather and dribbling down to the oil filter?
I am thinking forged may have blow-by pressurizing a bit before it warms up and pushing out a little oil via the breather.

Who built the engine?
Sounds like the gasket is on the wrong way round. This is where it usually leaks if that is the case.

Im sure he said the gasket only went on one way tho, it appears to be coming from around the timming belt side and dripping around to the front maybe? I have a picture but dont know how to upload it, sound for da help lads.

hmmm. I have a leak on mine that is from he rear left corner (I think) it runs down the cambelt cover and drips of the bottom of that. I have the head skimmed.

I need to investigate it. its not a bad leak, fortunately!

my other engine never got the head skimmed and is dry as a bone!!!!!

it could be the Athena gasket causing the problem.

sometimes on the Athena gaskets the rivets that hold the layers of gaskets together get in the way of the head bolting down properly, best thing to do with the Athena gaskets is to remove the rivets before bolting the head down.

There's a few seals that could leak on that side of the engine. If you take the timing belt covers off (top and bottom) then run the engine you may be able to pinpoint where it is coming from a bit easier mate.

The gaskets can go on the wrong way/upside down. Has been done quite a few times recently. I've also seen from a few people having problems with the Athena gaskets as well, possibly a bad batch?

As said above though, remove the timing belt covers if you suspect its coming from the side.

hoping you find it and as Jay says, best bet is to run the engine with the belt covers off to try spot the leak. if you've re-striped it already then this may no longer be viable.. :/

I could put up pics and show ye? But i dont knw how ha, the head gasket is warpd in the center, head is off again so i cant run it to see the leak but the oil is stil visable at the front left of the engine but no sign of oil around the timing belt side.

special needs..?! lol! well, the block and head have guides at opposing corners to help them mate in only one direction.. so unless guys remove these guides.. which is necessary anyway when skimming.. then don't return them..

If you class something as foolproof you obviously haven't met the appropriately ingenious fool :

I've heard of people doing this before, the genuine gasket only allows those two positions. Scary huh?

I've come across something similar before. There are usually seals behind the cam and crank gears where they meet the block. Of course they're hardly visible from the engine bay and a good clean of the oily area would be required to pinpoint where its exactly coming from. I think they're available from camskill although not too sure on the price. Would be worth checking underneath while the car is running so you have a better idea of where it could be from. You could also try leaving some newspaper under the car over night and if there is any dripping, use that to figure out which area its from. Best of luck mate, hopefully its not the case of the gasket being the wrong way round.

I just fail to see how people can lack that amount of inteligence
