Small problem

[reopeadres]

I have a 1984 toyota pickup with a 22r motor. For some reason after i drive about 5-10 miles it starts misfiring it seems like. It also starts to suck air threw the exhast pipe. I can hold a pice of what ever over the end of the pipe about a half of an inch and it will suck the thing to the pipe and then blow it back. Any ideas would me much helpful. Also I have put sea foam in to the gas, carb, and crankcase to eat up the carbon build up. Thanks

This is the tell tale sign of either a leaking head gasket, or leaking valves. I have it had happen on a couple of different vehicles. Once your engine warms up, the metal expands and causes the leak.
