CHEVROLET VENTURE POPPING NOISE
This is a 1999 Chevrolet Venture, with 200,000 kms on it. I bought it
and it had one flaw. The intake manifold gasket was broken. I opened it, i replaced the gaskets with brand new ones, and everything was running perfect, but one little sound at the rocking arms came up. I checked, and i forgot that the rocking arms should of been tightened at 45 degrees, where i only did 15 degrees. I re-opened everything, and tighten them. But this time i also changed the sparkplugs and the cables, and the distribuitor. Now i put everything together, and the rocking arm popping was gone, but a bigger flaw came up. Now everytime i accelerate it on low rpm (Parking Gear), it does some popping. Whenever accelerated a bit, it makes a poping sound. Like i press the gas ( and POP right away after pressing on gas). I turned off the engine started it again, everything ran smooth, but as soon as i started to accelerate it a bit, it would POP. At some point it started to POP POPPOPOPOP, so i turned off the engine. Any ideas what that could be? Too tight on the Rocking arms, or spark plugs, or WHAT ELSE could it be!! THANKS! |

Thanks for your answer man, but the firing order is perfect and no leak
in the intake has taken place by the way. It is indeed mounting flaw. Thanks |

If it is popping back threw intake it is a valve not opening right. Go back over rocker arms and push rods. Some have long and short push rods. Check for a tight one or one not opening valve.

all your replays, and yet, MT-2500 is the only one who actually guessed the problem. |
