On the exhaust manifold, the bolts break off at the head of the bolt whether the vehicle is in motion or not. Sometimes the bolts break off flush with the manifold and sometimes they break off flush with the head. I personally have had 6 out of the 12 bolts on my engine break off. The fix is to drill out the remaining piece of bolt (threaded part) and then use a bolt extractor to remove the remaining piece of bolt that is still seized in the head. Well, the most common bolt to break off out of the 12 manifold bolts is the one directly in front of the drivers position. Unfortunately, that is the hardest bolt to remove because of it's location. Most shops I've been to say that the ticking sound that you hear once this bolt breaks off is a loose lifter. That is incorrect! The ticking sound is actually an exhaust leak stemming from, most likely, the broken bolt directly in front of the driver. The sound goes away once the engine warms up because of the metal expanding with the temperature increase. I had 3 mechanics under the hood of my truck for almost 9 hours trying to remove the 6 bolts that had broken on my engine. They had broken every drill bit in their shop (the shop is a 14 lift, 16 bay shop) that could possibly be used to drill a hole for the extractor just trying to get a hole for the extractor to fit in and then the bolt extractor broke off in the last bolt which happened to be the one directly in front of the driver. They had the cross member removed and were preparing to drop my engine when I told them to just stop there. I couldn't afford any more of a fix since I was $1,800 deep into this one day at the shop as it was. This is such a common problem that there are aftermarket contraptions to bolt on and cinch the manifold down with another bolt. That isn't the right thing to do. There should be a recall and I should get reimbursed!

Tl*the contact owns a 2000 chevrolet silverado 1500. When the vehicle is cold and is started, the engine knocks from thirty seconds to one minute. Once the vehicle has warmed, the knocking stops. General motors stated that this was characteristic of the vehicle and is known as engine knock cold start, or carbon build up on the piston head. The contact was informed that the repair would be his responsibility. The current mileage was 50,000 and failure mileage was 49,000.

The pistons in the engine are knocking. The dealer states they cannot hear the noise which is quite obvious and getting louder. The vehicle has been twice for this problem and still it is not corrected. We have contacted the manufacturer, bbb, congressman, atty general, in hopes to have something done to prevent the locup of this engine. If the engine were to lockup at 70mph on the intersate there could be a bad accident. There are several hundreds if not thousands of people with the same problem. There is even a website dedicated to the problem http://www.gmpistonslap.cjb.net/. Thank you.

Lifters knock at startup all the time. Dealer has replaced lifters, used heavy grade oil and cleaners, higher grade gasoline used for six months, nothing has stopped the knocking. Service manager has stated that general motors has a problem with the 3.5l engines and this dealership has worked on the same problem with many other customers whom purchased the 1999/2000 series trucks with this engine, including replacing the engine, but, he would not put into writing what he was telling me. I have been waiting for a meeting with the gm rep. For about 3 weeks and still do not have an appointment.
