I have a D16Y8 with a full Crower head and pnp and an edelbrock Intake Manifold. I recently put the head on, and i know the car is going to lope at idle, but it wouldnt even idle and would shut off when the rpm's dropped. I did a cylinder leak test, and cylinders 1, 2, and 4 were fine. cylinder 3 had a 50% leak out of the intake, mind you these are brand new valves, with a new valve job, etc. I've ruled out a bent valve or a messed up valve seat, because it works fine when cold (and wont leak when cold), but when it warms up, starts to mess up. Does anybody here have an idea of what it could be? Ive been looking into this all day, and its driving me insane. Thanks in advance,

Nick

maybe a seating problem or rings ...

im leaning towards a seating problem, because the bottom end was fine when we pulled the old head off. my question about the seating problem is, why would it not act up all the time, and only when warm?

only warm because metal expands when it gets warm. check those valves again when the motor is still hot. or any where for a leak when the motor is hot. the thing that works for me is some verry soapy spray. and sypay it aroung some seals when runing. if it bubbles then u have a prolbem. be shure and carfull not to get it into the engine!
