I just did a compression test in the vehicle.
My crankshaft pulley fell off, fixed everything to the best of my knowledge. When I crank the vehicle, there is white smoke that comes out of the exhaust. It seems the clear up as the vehicle idles.

When the vehicle idles it seems to run decent 1200 -1400rpm (330k miles) however it seems to want to throttle down to 500 rpm to the point that it sounds like it would die but I throttle it and it perks back up.

I did a compression test and the results were

#1 133
#2 174
#3 175
#4 174

Someone told me bent valve, another friend said that if it get's that much pressure then it could be something else.

The car isnt worth much money, but I'm strapped for cash at the moment. Trying to keep this car running for just another 12 months and then my wife's car will be paid for and I can afford to find a used replacement. Thanks guys.

 

Leakdown test will tell you if its bent exhaust valve bent intake valve or head gasket.

 

Do the compression test again. But this time remove the valve in the compression tester. Then watch how fast each cylinder loses pressure. If it has a burnt valve it will leak out very quickly. Also you can turn the motor by hand and blow air into the spark plug hole. If you hear air coming from the exhaust or intake, you have a burnt valve.
