I own a 1999 oldsmobile silhouette with about 55,000 miles. I took the van to a local mechanic because of a knocking noise on cold startup and continual overheating. The mechanic diagnosed the problem as a failed intake manifold gasket. The total bill about $600. The van had regular maintenance. This seems to be a common problem with gm vehicles with the 3.4l engines.

What owners say
Car went to dealer to diagnose a knocking sound on cold startup. Diagnosed as a failed intake manifold gasket, cost to repair approx $900.00. On disassembly, dealer contacted me and stated that the engine internals were so badly fouled (sludge and deposits) that hydraulic lifters needed replacement, cost approx $450.00. I asked how this could have happened, van has always had engine oil changed at 3000 mile intervals, with new filter and correct oil, and I don't know what to do differently to avoid this happening again. No advice offered, and no suggestions for why the gasket had failed.
I own a 1999 oldsmobile silhouette with 64,000 miles. I took the van to a local dealer because of a knocking noise on cold startup. The dealer diagnosed the problem as a failed intake manifold gasket. The failed gasket ruined the hydraulic lifters and had to be replaced. The total bill was $1500. The van had regular maintenance (oil, filters, anitfreeze checked) every 3000 miles. This seems to be a common problem with gm vehicles and dexcool systems. This could have been a major safety issue had the engine failed while driving.

Diagnosed as a failed intake manifold gasket, cost to repair approx $900.00. On disassembly, dealer contacted me with information that the engine internals were so badly fouled (sludge and deposits) that the hydraulic lifters required replacement. I asked what could have caused this situation, since the van has always gotten regular oil changes every 3000 miles, with new filter and correct oil, and I don't know what to do differently to avoid this same problem again. No information or advice was offered on why the gasket failed, or why the engine was so badly fouled.
Automatic transmission malfunctions, causing a knocking noise everytime the occupant changes gears and may cause loss of vehicle control. Please provide further information.
