Oil pan gasket question

Hello everyone,

 

well, here's another dilema for all the engine guru's out there. I was getting on the gas, doing about 40 rpm's were about 4750 to 5000. White blueish smoke started to follow me. Turns out after I pulled the engine it is the oil pan gasket. I just put a new felpro on recently. I used there new material, the non cork kind. I did it with out pulling the engine. I guess what I'm asking, is I thought I remember hearing something about that it could be caused by improper crank case ventilation. I have k&n filters on both of the valve covers, and edlebrock's chrome valve covers. Any ideas, or could it just have been, I didn't get the bottom of the block completely clean before I put it on. Thanks for any and all info.

first you should be aware that there are two different front seal thicknesses one is about 1/4" thick and one is about 3/8" thick so if you use the thin seal on a oilpan designed to use the thick seal it will leak most of the time, next , you should know a VERY COMMON MISTAKE is not installing the bolt that goes in from the front of the block where the fuel pump mounts,(BTW if you use to long of a bolt here it locks the fuel pump push rod and your fuel pump stops working) this will only leak noticeable amounts of oil when your rpms get over about 3000 plus and it at first apears the fuel pump is leaking oil. next thing is that useing studs in the block to locate the pan gasket and pan and nuts on the studs to lock the pan in place works far better than useing bolts, and yes the 4 corner bolts are bigger than the other bolts. next be aware that the better gaskets are now ONE PIECE PLASTIC GASKETS with the side rails and end gaskets molded in one piece. look here,under oilpan gaskets

fel-pro also makes them in both right and left hand dip stick models just ask any parts store that carries fel-pro gaskets (they cost about $30 but are reuseable and well worth the money)

Thank you Grumpyvette:

 

You saved me about $50.00 and several hours under the car. I thought I had a blown timing cover seal or front pan seal due to an pool of oil collecting under the fuel pump blockplate and on the cross member on the passenger side. We really noticed it while driving on the freeway with no hood. Oil was spraying back onto the windshield. I checked for the bolts on the front of the engine block near the the fuel pump and sure enough there were no bolts and the holes go all the way through the block. At high RPM oil would blow out of the empty bolt holes. I installed two bolts in the offending holes and there are no more oil leaks!!!
