Problem Reports

excessive oil consumption, replaced plenum gasket, some technicians I find out know reccomend replacing the aluminum plate, due to warpage.

I have a 5.2 v-8 it was using 1 quart of oil every 50 miles and i replaced the intake gasket and it stopped

Engine used several quarts of oil in a short period of time. No smoke out the tailpipe or leaks. Discovered oil was going into cylinder and burning but the catalytic converter kept things clean until it failed by clogging. Poured an oil treatment into crankcase and got instant fix for the last 20K miles. Plan to open the motor and expect a bad intake gasket to be found. May rebuild motor completely.

when i accelerate up a hill or when the truck is under load the intake makes a pinging noise. you can test this by taking the throttle body off and looking into the intake if there is oil in the intake then it is most definitely the intake plenum gasket you can get a kit from auto zone that is around 50.00 bucks. remember that if you remove the intake manifold you are going to have to replace the intake manifold gasket along with the plenum gasket. when removing the intake manifold make sure that you do not crack the fuel rail they are hard to find.

Excessive oil consumption and sperk knoch. You could see oil in bottom of manifold when looking thru throttle body. Replaced and runs like new.
