Zac88 Posted June 18, 2010 Share Posted June 18, 2010 Theres a weird knocking or popping like noise coming from the front drivers side of my engine on a 2005 LGT wagon. Thats cylinder #2 i'm guessing? It only happens when the engine is under load. It idles fine. if I rev it up slowly it does not make the noise only if I floor it or accelerate quickly. I can post up a video if you guys like, it almost sounds like air escaping? Definetly does not sound like piston slap or a spun bearing. Link to comment Share on other sites More sharing options...

ehsnils Posted June 20, 2010 Share Posted June 20, 2010 Check the header and gaskets around the header too. Also check the oil so it doesn't contain water. Link to comment Share on other sites More sharing options...
Zac88 Posted June 20, 2010 Author Share Posted June 20, 2010 Just did an oil change couple days ago but the sound is still there. I'll get under the car tomorow and check for exhaust leaks. Link to comment Share on other sites More sharing options...

ehsnils Posted June 21, 2010 Share Posted June 21, 2010 I was more thinking of water in the oil as an indication of a failed headgasket. Link to comment Share on other sites More sharing options...
OhBe1 Posted June 21, 2010 Share Posted June 21, 2010 So the sounds was there before the oil change?

Zac88 Posted June 21, 2010 Author Share Posted June 21, 2010 Sound has only been there for 2 weeks now. Sound was there before this last oil change. I have done 3 oil changes on the car now, I have owned it since april with 108,000km on it. 122,000km on the car so about 60,000 miles? Link to comment Share on other sites More sharing options...
