Need some advice-New Crate motor
 O.K. , I know this is not uncommon. I have seen this before, but I need some advice. My new crate motor has a with new Edelbrock intake with APR intake bolts, Fel-Pro gaskets, etc. The two center bolts on both sides are seeping oil up around the bolts. I used ARP thread sealer on all the bolts and carefully torqued the bolts. I really would like to stop this oil leak on an all new engine. Assuming (I know that's dangerous) the thread sealer is doing it's job, is it possible the the oil is seeping due to the holes in the intake. I am going to pull the bolts out tomorrow and clean the threads carefully and re-seal with the thread sealer. Would it help to put a small ring of RTV sealer just below the heads of the bolts or maybe add some SAE flatwashers? I have a new PCV valve on one valve cover and a new push-in breather on the other. Is there that much crankcase pressure to makes the leaks?

Re: Need some advice-New Crate motor
Don't know if it makes a difference... but edelbrock makes their own gaskets specific to each intake. May want to start there?
The PVC set up described is what myself and many other people run, so that should be fine.

Re: Need some advice-New Crate motor
In additon to what is mentioned above i would spray a littlet brake parts cleaner into the threads on the head to rinse the oil off inmorder to get a good seal and reseal as mentioned above.

Re: Need some advice-New Crate motor
I have never figured out why this happens but it does. I took out the bolts & cleaned the holes like Wideside says & used RTV on them. That fixed 3 of them the first time & I did the fourth one again & that worked.

Re: Need some advice-New Crate motor
I have also heard of using a rubber o ring under the head of the bolt. I would assume you would need to lube the o ring to keep it from tearing.

Re: Need some advice-New Crate motor
I use high temp RTV on my bolts. Seems like the bolts on the drivers side center intake are the ones most prone to leak.
