I have a 87 Trans am with a SBC 406

ENGINE,
Eagle crank
Eagle 6-inch H-beam rods
SRP dished pistions (9:1)ish
Sportsman 2 Heads
Cometic MLS head gaskets (Put on the copper coating)
Comp cams extreme energy 284h
Gold crane 1.6 roller rockers
Victor jr. intake
850 demon

The problem im having is, Im getting water in the engine oil i had brand new oil in the car after 10 minutes of ideling it was white. Ive had the engine apart a few times trying to figure out the problem but cant seem to pin point the location of the leak any ideas would be awsome if you got any questions feel free to ask i think i got it all down

Couple pictures of the engine. The one of the engine in the car is before the victor jr. Im going to put that one back on the car this weekend to see if it cures my water in the oil problem

As in a 70s block?
IIRC, there's something on the block // heads for steam, but Idont recall
what to do with the holes. I don't think a head gasket will fo the trick by itself.

Those head gaskest go on dry, no sealer. I would also run a normal felpro gasket on this motor.
Are the heads drilled for steam holes?
Did yo have the machine shop psi test the block and or check it for cracks?? I dumped 4 509 blocks b4 I found a "good" one.

Also check your intake gaskets.

Yes there are steams holes and i have them opened up in the head gaskets like there suppose to be i do believe

Ok we had them dry and it was leaking so thought that could be a problem so we tried it as for the intake gaskets Ive tried a few different ones and took extra care to make sure everything was how it was suppose to be. Gonna try and intake we have laying around to see if it might be the intake

as for the block i havent yet, i didnt have this problem tell the cam swap we did about 2 weeks ago

Did you pull the heads for the cam swap?

If it wasn't leaking befor the cam swap it shouldn't be now unless there is some gasket material stuck and making it leak.

I see you are using head studs also. Those are a pain to seal up. Did you reapply thread sealer to the block threads??
I would ditch the head studs unless your planning forced induction down the road.

Yes i pulled the heads and i did you a sealer on the threads in to the block and i spent more time cleaning the engine then it took to swap the cam and lifters

I am going to swap the head gaskets i just didnt want to with the cometic gaskets being 200 bucks for them didnt want to toss them out

I am that was the reason for the cometic head gaskets and the studs
