i install a new trick flow manifold and when i went to start it up a slew of problems arose. my rpms run between 1,100 and 1,500 and oil leaks from my oil plugs on my valve covers. i've taken the intake manifold back off to check if the gaskets had slipped. they hadn't. i replace the termostat, it didn't help, re-adjusted the tps to as close to 1.0 volts, helped a little bit but not really. adjusted the timing to 10 degrees, didn't help. i've changed the oil thinking that maybe some coolant mixed with the oil. there was a liitle bit of mixture but didn't help. i'm going to put on a buddies ford motorsport valve cover next. please give me some ideas. every piece of info i've recieved i've used to no prevail.
