Exhaust and manifold cover bolts are too weak and the heads break off. I had to replace all of them with racing bolts. Much better now.

- What is wrong
- On certain pickup trucks equipped with an 8.1l v8 engine, the crankshaft position can operate intermittently or fail completely. If the sensor operates intermittently, the ses light may illuminate and the vehicle may run rough. The engine may stall, and if so, may re-start immediately or after a cool down period.
- Risk
- If the sensor becomes completely inoperative, the engine will quit running and will not re-start. Either of these failures can increase the risk of a crash.
- Remedy
- Dealers will replace the crankshaft position sensor free of charge. The recall began on december 18, 2007. Owners may contact chevrolet at 1‑800‑630‑2438 and gmc at 1‑866‑996‑9463.

Crank position sensor failure - stall
The office of defects investigation (odi) opened a preliminary evaluation (pe06-016) on may 4, 2006 based on eleven vehicle owner questionnaires (voqs) and early warning (ewr) data alleging sudden engine shutdown while driving as a result of crank position sensor failures in my 2001-2002 general motors c/k platform vehicles equipped with 8.1l engines.in response to an information request letter sent by odi, general motors (gm) provided owner complaint information, field reports and warranty claim data based on a population of 108,338 vehicles. The data was categorized by engine stalls while driving, engine stalls with an unknown driving condition, no start conditions and claims where it was indeterminate if an engine stall occurred while driving.general motor's response included 1,213 owner complaints and field reports of which 289 were categorized as engine stalls while driving allegedly caused by crank position sensor failures. General motors also submitted warranty claims from its regular warranty (5 years/50,000 miles) and from its extended warranty database. From the regular warranty database there were 3,140 claims of crank position sensor replacement of which 147 claims were from consumers alleging engine stall while driving.gm stated that 2,841 of the claims were indeterminate if an engine stall occurred while driving.from its extended warranty database, gm submitted 1,561 claims of crank position sensor failure that it also stated were indeterminate as to whether an engine stall occurred while driving.in total, gm reports 4,701 claims of crank position sensor failure combining regular warranty and extended warranty.similar to gm's statistical analysis, odi's analysis showed that the failure rate for warranty claims of engine stall while driving at three years in service is low (less than 1%).however, further analysis determined that the my 2001 vehicle build period from may 2000 through october 2000 had significantly higher (more than four times) crank position failure rates in both consumer complaint data and warranty claim data than in the build period from november 2000 through july 2001.adding the claims of known engine stall while driving and claims where engine stall was indeterminate, the failure rate at three years in service for this population is over 6%.an engineering analysis (ea06-016) has been opened to further assess the frequency and potential safety consequences associated with the alleged defect in vehicles built from may 2000 through october 2000.

The bolts that hold the exhaust manifolds down are breaking off at the heads and causing exhaust leaks. Which are in turn causing my catalytic converters fail prematurely. I hope gm fixes this massive problem with there ls v8 engines!
