GPdriver1986 Posted August 30, 2003 Report Share Posted August 30, 2003 I had an oil leak this whole time and I didn't even notice that it was coming from the oil drain plug. I even took the time to change the o-ring. I replaced the drain plug a few days ago when I did an oil change. I used a good drain plug that we saved from our old 2.8 Corsica. When I took out the old drain plug on the GP I noticed that the thread on the plug was kinda striped. So I put the new drain plug on and it went in ok but kinda had a hard time putting it in. It wasn't leaking oil for about 2 days now its started leaking oil again. I think its either the thread on the oil pan or its not tight enough. This whole thing explains why I only leaked oil from the engine when it was cold. Any opinions? Quote Link to comment Share on other sites More sharing options...
Redfox340 Posted August 30, 2003 Report Share Posted August 30, 2003 Find a OEM replacement plug from either Autozone, etc. I forget the exact dimensions it's know as a Chevy corse plug. If that doesn't work, you'll have to tap the pan and put in a oversized drain plug. After seeing tons of oil pans @ Grease Monkey, some people just love to wrench on those bastards... yeesh... - Erik Quote Link to comment Share on other sites More sharing options...
GPdriver1986 Posted August 30, 2003 Author Report Share Posted August 30, 2003 From what I know the oil was changed every 5k km at the Crappy Tire. I went to crappy tire to check for drain plugs, I noticed that the 2.8/3.1 uses the same drain plug. Quote Link to comment Share on other sites More sharing options...
GRANDFURY Posted August 30, 2003 Report Share Posted August 30, 2003 I had the same problem, bought a new oe plug and o-ring and mine still leaks too. I think you're right I took the car to Q-lube once and they just cranked on the plug and filter :x bastards, now I think I have a small crack in the pan it self. I'm going to try some JB weld for a quick fix. Quote Link to comment Share on other sites More sharing options...
GPdriver1986 Posted August 30, 2003 Author Report Share Posted August 30, 2003 The real world sucks, I'm 17 and I wouldn't trust anyone to change my oil, maybe dealership thats it. Most of these places (10 min oil change) don't care about your car and overtighten everything. Should I use a tap and die set to redo the thread?????????????????

Redfox340 Posted August 30, 2003 Report Share Posted August 30, 2003 Should I use a tap and die set to redo the thread??? Yeah, if a new OEM corse plug doesn't work out, gently tap the pan. Make sure after taping that you flush a quart of oil through the open oil crankcase. - Erik Quote Link to comment Share on other sites More sharing options...
