2004 Colorado having issues.....
I wanted to see if anyone else was having issues like this or knew anything about this.
I have an 04 Colorado with the 2.8 L, that I just bought so I dont know the service history. It idles really bad like there is either a vaccum leak or something along those lines. It is worse when you are coming to a stop and let off the throttle. It never dies though, just seems like it might.
The other day while this was happening the oil light came on and a chime went off. When I stopped to get fuel I went ahead and checked the oil level. On the dipstick the level was full, but it was "foamy" like there was water in the oil. I am thinking this might be a sign of a leaking head gasket. If this is the case I am wanting to find out if anyone has ever dealt with this and to find out if these trucks have a problem with the heads cracking or is this something that I can just pull apart and send the head to be milled and then reinstall with a new gaskst.
Any help will be greatly appreciated.
I am a BMW mechainc, but I have never dealt with these trucks. So I do have mechanical knowledge. I am just trying to find out if this is a common occurence or anything really.

A guy I work with had a 2005 Chevy Colorado he bought brand new, it had the 3.5 though. His truck was doing the same thing as yours, so he took it to the dealer and the found that when the engine was put together whoever put the gasket on put it on backwards. So they fixed it under warranty, but I actually saw pictures of it and it was obviously put on incorrectly. Just a little head up, he only had 10,000 miles on his truck when that happened.2004 Chevy Colorado
