help my car doesn't pull
 

i have an 87 gt with a t-5 with and some modes heres my problem'ssss
1)car runs good for the first 5 minutes and then it has no power and when i try to rev it stumbles i just gave it a tune up cap rotor plugs i did not do the other stuff like wires and pvc and fuel filter cuz i did the like 6 moths ago.
2)after driving the car it steams like crazy out of the breather on the head and when i pull out the dip stick the oil is all up and down it and is really hot.
3)after giving the car gas in any gear and then coming off the gas the car jumps or bogs like some one that can't drive stick was stalling it.
4)this kinda goes with the first probable but it doesn't happen all the time when going from a stop the car stables doesn't really matter rpm even and if i rev it and dump the clutch it stalls out.

my modes are gt40 intake edlebrock aluminum heads 1.6 roller rockers mac long tubes to flowmasters with an off road h pipe no ac no emissions stuff and 355 gears i think forgot some stuff but that's all i can think of now.

any help or tips on what to check for would be the a great help because i am lost and very pissed off

Sounds like blow by to me....that sucks.

Later,

You have some electrical problems here, lets think about it, without being arrogant, is the firing order correct, timing correct, dont care if you did wires and plugs earlier, check them anyway, i also suspect the engine ground, how about the smaller lead off the negative battery cable, is it grounded properly/ (computer ground location), could be the TFI module on the distributor, is the SPOUT connector connected?, Vacuum?, fuel pressure at 38-42?. You are speed density, this relies heavily on the MAP sensor, 02 sensors, and the ECT and the ACT sensors, are these fresh? get an EEC tester, I'll sell you mine for $10.00 dollars, private message me!

Try these suggestions........

Whew!!! I'm out of keyboard breath!!!!!!!!!:D

Steams out of the breather on the head? Oil is all over the dipstick and very hot? Any leaks that you can see. What do you gauges read?

I just had a 95 f-150 do that, with the hot oil, and i mean very hot! i blistered my fingers only after it ran long enough to run codes, i stil dont know what that thing problem is, it did have an oil pump quit, it was replaced now it runs, just not good.

hope you get it figured out.

this might not help you but, 3 buddies and myself have had mass air's go bad and when they go bad the car will fall on its face when floored but run OK at part throttle, just try disconnecting your mass air and see if that helps, i dont know about your steam out of the breather problem, to me that would suggest blow by. or maybe some vaccum lines hooked up wrong.
