I have a 2006 Canyon 5 cyl I just bought with 48000 miles. At idle there is an engine tapping noise, but it doesnt sound like a knock. My mechanic said it sounds like a tapping lifter and thicker oil will quiet it. My friends said chevy trucks do it too. Has anyone else noticed this problem and does it mean anything is or will break?

myrtlecanyon, You probably have the dreaded loose valve seat. Have a dealer check your truck. A special extended warrantee (to 100,000 miles on all Canyon/Colorado 4 & 5 cyl.) will fully cover the cost of a cylinder head replacement. Do not let them sell you anything else or charge you. Good luck, Russ |

Replying to: falcon19 (Jul 14, 2009 5:53 pm) This letter, essentially stated that the engines on these vehicles were given an extended warranty for 7yrs/100,000 miles. Yes, if your engine is making new, and/or strange noises, you should have it looked at by the dealer ASAP. If it is indeed a cylinder head issue, the repair, if paid out of pocket", would be near $3000, parts and labor. However, you said "valve cover"....I doubt a valve cover repair/replacement would cost $3000. FWIW, my Canyon is now 4.5 years old, with 27,000 miles. Presently, it's running like a champ. IF, and I repeat IF, the head is one of the bad ones, I hope it craps out soon. I don't want to have to shell out the $$ myself, if if goes bad after the 7 year warranty is up...assming GM is still in business and honoring "old" waranties!!

Replying to: falcon19 (Jul 31, 2009 9:25 pm) I found "The Letter". I had received it in November 2008 and my wife had filed it away without telling me. It says that in "some" 2006 Colorados "engine valve seats may wear." A tipoff that this is happening is that the Service Engine Soon (SES) may come on and "additional wear may lead to engine idle roughness." Anyhow, the letter is a notification that the warranty for this problem is now 7 years or 100,000 miles from the date of purchase. Good news! Here is a phone number contained in the letter for any questions regarding this: 1-800-630-2438. Hope this is helpful, Joe

I've been experiencing engine and various electronic issues with my 05 Colorado from DAY 1 such as: rough starting (shuddering) and running, no starting, 4WD and emergency flashers inadvertantly engaging, trailer lights (loom wiring) not functioning, headlamps out, ABS sensor fault, seal issues -- blah blah. The list goes on. 3 different parts were changed on three different occasions for the 4WD issue, and a throttle body assembly and injector feed wire were replaced for the starting issues. I currently have 81K on the truck and I'm now experiencing unpredictable, infrequent start-up problems (again) ever since I ran my fuel down to a LOW FUEL WARNING level. It's crazy. I can run for several days, then boom -- no start. It will crank with no engine turnover. In each instance, the engine will eventually turnover after a few tries and then turning the ignition switch on after having let it sit for several minutes. A mechanic had advised pounding on the fuel tank on one occasion which seemed to get immediate results, although I wasn't sure if it was because of sitting idle after repeated cranking. There have also been other instances when tank rapping hasn't worked. I've had two different GM mechanics and a veteran GM exec acknowledge fuel pump issues with their products although I'm not so sure after reading some message postings on the Edmunds forum. One guy said it could be an electrical contact issue with the pump, a hot spot that will react irregularly when the engine is hot, cold, idle for awhile, etc. etc. -- blah, blah. He said the newer fule pumps will slowly fail as opposed to outright failure common to past defections. I've had two guys check it for codes and there are none. I've put a fuel pressure gauge on the valve and get 53 -55 lbs of pressure when the non-start gremlin magically appears. It seems likely that the pump is functioning properly with that amount of pressure even during the no-start condition. I don't want to drop 3 bills for a pump and find out it's not the problem. It will be more if I take it to a dealer. PLEASE HELP!!! Can anybody offer"> a suggestion -- other than a flare?
