Loose oil

Hello everybody !

My name is Jean-Philippe, and i live in France (sorry my English is bad). I'm new in this forum, and i have a Trans am LT1 1994.

I make some modifications : cold air intake, lightweight underdrive pulleys, hooker headers, off-road y-pipes, slp loud mouth, msd distributor, msd spark plugs wires, trick flow cylinder head...

But i have a problem, every 200miles i loose oil by my cylinder head, the cylinder head bolt fall.

What is the problem ?

Thanks you very much

Maybe the intake gasket(common)or the valve cover gaskets could be leaking.Wash everything down and make sure the oil is full.Then start the car and let it run for a few minutes and see if oil is leaking from somewhere.I doubt oil is leaking from the head gaskets.

Did you put sealant on the front and rear rails of the block where the intake sits? You cannot put the intake manifold on with just the gaskets. I did a crappy little picture in case you do not know what I'm talking about.

If you or your builder did not get the intake walls (china walls) clean enough, the silicone will not stick to it and you end up with your oil leak again.
