Car keeps blow lim gasket

So car was running great then all of a sudden would not rev past 2500 rpm car reset my power fc and blew my leading coil re put tune on it replaced coil. Starts up keeps blowing my lower intake manifold gasket. Pull it off and their is a bunch of fuel in my secondary intake runners that keeps seeping through the gasket
I've tried timing 0degrees and at factory 5 degrees atdc running stock coils trailing modded for direct spark. Replaced fpr unplugged knock sensor made sure injectors were not seized. New fuel filter and lines

What do you mean it keeps blowing the gasket? Are you assuming this because fuel is dripping from it?

Youre sure its oil? I think its normal for oil to be in the LIM. only thing i can think of is either a blown oil seal in your turbo or your OMP system.

Having a hard time understanding you. First you said it was oil, and now youre saying it's premix?

My car leaks vacuum and fuel vapors if I only use the paper gasket where the lim mates to the block. Are you using silicone on it as well?

It's totally normal for fuel/oil to end up in intake manifold. Due to reversion.

This is the first time I've ever heard of an intake gasket blowing.

Are you using the OEM gaskets?

Mating surface clean?

Manifold flat?

Torque specs followed?
