so im sure every one by now knows whats goin on w my snake!! just an update for those who are just joining us,,, i put an mmr 900 (new motor) in the car, along with a d1sc (procharger)!! so any way i have everything together, but i have a bit of a problem!! actually thats an understatement!! i have one hell of a problem!! i have an oil leak that cwo and myself have bn trackin for about a week now! the car starts, the car will run,,, not well, of course, because its not tuned!! but it will run!! however, when you put oil in it lets say a quart youll get about a tenth of a court leaking out! after much looking and pulling of peices here and there, and many many tricks, i have found the leak and its what i feared!! the oil is coming from the base of the head about two inches back from the front face!!! this is devastating news, unless someone knows a trick to keep this leak from continuing, and making the motor good to go, it looks like im gonna be pulling heads after just putting the heads in!! this is really a set back so id llike to get this issue solved as soon as possible,, if anyone knows any tips that may be able to spare me from pulling the heads im all ears!! now, it seems as though there is no option but pulling the heads back off, so providing i do pull the heads, i have heard that there is a way to pull the heads wo removing the timing chain cover!!!! so if anyone knows how to go about this, it would be greatly appreciated!!! and lastly i have also heard around the club of a guy here in socal somewhere, possibly up near la!!! who takes heads and ports them w no down time!!! so in essence he takes your heads and gives you a set of ported heads, so there is no hang up, if i do end up getting new heads i would like to get them ported while theyre out of the car, so if anyone knows the name of this guy that would aswell be greatly appreciated!!thanks in advance for all the input and help guys, i alwayse get the answeres im lookin for when i post up around here!!

Do it right. Take the heads and top end apart to fix it. If you dont it will only get worse. You will end up doing it later anyway. With that engine, I would redo it to make sure it was good to go.

arent they new?
If they arent, do any mods you have planned then reassemble. Take your time and it will pay off in the end....

If you have oil coming out from under the head then I would say you have pinched the gasket which is hard to do. Are you sure you torques the head bolts in the proper sequence and in steps like they were supposed to be? If not you could have warped the head. I am sorry to have bad news but on a new moter that is usually a bad sign!!!!!
I would say pulling the head is a must to see exactly what is wrong and do not continue to run it like that.
not new, but they were on the original motor and there was nothing wrongwith them originaly, theyve alwayse worked for me!!!LOLOL!!! so any ideas what could be makin it do this now?? i was thinking originaly that possibly there just not torqued correctly for what ever reason, which i guess could be possible, highly unlikely i double checked them before i put the valve covers back on, so i would say not but i guess it is possible!! and if thats the case do you think that i could attempt to torque/retorque that one bolt?? or do you think it would already be trashed??
Did you by chance notice one that didnt quite torque down right or felt like it spun????? If that is the case then you will need some head work. It does not take much of a goof up on heads to make them either leak or blow the gasket.
you have to torque head bolt in like three stages and it is highly and I mean HIGHLY recommended that you use brand NEW bolts. The old ones get stretched and do not torque correctly 8 out of 10 times.
nope followed all the steps exactly, just because i knew that i could jack the heads so easily,,, everything felt perfect!! no problems,, i dont feel like there are any problems w the exception of that leak,,, double checked the torque too!!! but i wonder that if there is some freak way that for what ever reason there is that one bolt that just got a bit squirly, maybe it wasnt fully torqued at that second 90 degrees, maybe for some reason i only went 70 or somethin!!! at that point it would explain the leak but would it be fine to finish the torque on that one bolt and throw the covers back on and try her again!!??
You could try to check the torques but there is no set torque in the final step. It is just a 90 degree turn and how would you know how far you went the first time??????
I am wondering if one of the bolts stripped? It is uncommon to do but normally you wont get them to torque fully.
where did you get the torqing sequence from?
well yose, when i torqued them i put a small white line on all the bolts and that was my referance,,,, the pattern is torque, what ever it is,,,, on all bolts,,,, 90 degrees on all bolts,,, then another 90 degrees on all bolts,,, so in the end all the lines are pointed the same direction!! i would know if there was one bolt that was off because the line would be canted away from the others!!! and when i torqed them none of them felt like they stripped, spun, broke, sheared, or anything abnormal!!! everything felt perfect!!
Then is there a chance that you got the gasket upside down? Or torn it setting the head on the block?

I have to agree with yosi. Something happened to the gasket during assembly. Happens from time to time. Sucks that you have to dig that deep again, but it's not really optional at this point.
You didnt leave the heads setting valve side down on concrete did you?
nope didnt, when they were setting anywhere,, they were setting on the cam girtle!!! upside down!! valves to the sky!!
so if im pulling them again should i get the botom re surfaced, or should it be good,,, just throw another gasket on there and gently place everything back together!!!
