| Started my truck one day and heard a noise i haven't heard before. looked under hood to see where it was coming from and noticed noise was coming from the exhaust manifold. the bolts have broken off leaving the manifold leaking exhaust fumes. came to find out that this is a common but very dangerous problem on chevy trucks. many chevy vehicles have this issue and if not corrected could lead to more engine troubles or worse yet a fire.so now my vehicle is a safety hazard! chevy should recall this safety hazard, which could become dangerous. *tr | |||

| I have a 1999 chevy silverado that has been diagnosed with piston slap. this all started shortly after i purchased the vehicle in 1999. however, the dealer refused to fix it, stating that it is normal noise. (normal? then why didn't the engine make this noise when i first drove it off the lot)? i continued asking the dealer about the noise but they continued to say that it was normal noise. finally, i took the vehicle to another gm dealer on april, 2004. the vehicle had 48,799 miles. i asked the mechanic and service representative to listen to the engine, both determined the noise was not normal, and needed repaired. they performed numerous engine repairs that seemed, at that time, to make the noise go away. in june, 2004, the vehicle now had 49,023 miles, the noise had returned, and the gm dealer again stated the noise was not normal. they then replaced the long block of the engine, that seemed to have taken care of the problem. as of this date, the vehicle is back at the gm dealership with the same engine noise, which is a loud ticking/knocking noise. i am, again, being told is normal for this engine. (this is statement is being quoted by general motors, as being normal. initially, when i recently took the vehicle to the gm dealership, the service technicians indicated the noise was not normal...until the engineers at general motors conveyed the noise as being normal.) | |||

| This is the first new vehicle we have ever bought. but not a good expreience, we have always had gm products with no problems. we just had the truck in the garage and they put it on the computer, it said code po137 02 sensor bank 1 sensor 2 replace also code po300 misfire #7 cylinder replace injector and fuel pressure regulator. this cost 448.78. also po300 misfire #7 cylinder replace injector and fuel pressure regulator and code po463 fuel level sensor needs fuel sensor replaced at a cost of 301.00. we can't afford this at this time. they also said both front wheel bearings with speed sensors need replaced at a cost of 642.00. we can't have this done now either. we are going to try to get along with the brake failure long enough to save money to fix. we replaced the battery sept 11th at a cost of 65.00 and an alighment in june at a cost of 47.00 and rear brake rotors and pads replaced in july at a cost of 279.00. we had thought of trading or selling outright and getting another truck, but can't sell it as it is. | |||

| From the very begining, the engine, (5.3l), has made a ticking/knocking noise at start up (similar to what noisy lifters). i was told by the dealer some time ago, that is was faulty pistons, (piston slap), with no solution yet. i have since also heard this from addtional automotive resources. it has continued to get worse. i spoke to the dealer again today, and am meeting with him tomorrow, leaving my truck so they can start it in the morning. i just anticipate a lot of problems. he has told me that they have had many trucks come back for the same reason, and have even replaced entire engines. but he also said it could be carbon build up. i don't think so, because it was doing this from the first day off the lot. i hope i am wrong, but expect a very difficult battle to get the engine replaced. any information or help you can give me would be greatly appreciated. i have talked to numerous other truck owners with the same problem. some have had major repairs like new lifters, without success. but those who let the dealer do major repair, then later were told chevrolet would not take the motor back and put a new one in, because the dealer had already broke into the engine. (didn't mean to write a book, but really would like some help/support. this is a very new and expensive truck, and i should not have an engine knocking with 40,000 miles on it, particularly from day one. i take meticulous care of this truck and change the oil like clock work every 3500 miles. thanks so much for any help or direction you can provide! sincerely, doug malawey | |||

| I have a loud ticing noise coming from the left rear of the engine. while i was pulling my 5th wheel the noise kept getting louder and louder and had loss of power. by the time we got to the camp ground it sounded like i had lost my mufler. we took it to muffler man of ludington and they discovered that 4 exhaust manifold bolts had sheared off, 2 on left year and 2 on right rear of both manifolds. they took the manifolds off and replaced all the bolts with new ones except for the very left rear was sheared off flush and could not get a drill in to drill out and tap. in order for them to get this out they would have to pull the head which would have cost $1000.00. they put it back together and the tic was gone. this only cost me 6 hours of vacation with my family and $200.00. the tic has returned.*ak | |||

| Constant loud ticking noise from left side of engine/underbody. only audible while truck is in gear and under accelleration. suspect faulty catalytic converter or manifold to exhaust seals. if leaking, could pose health threat. dealership and chevrolet advised. so far, response is that is the way it was designed. noise is simply engine harmonics passing through tailpipe. i disagree | |||
