ill start with this ..there is a recall your car should be the one that the pistons cant hit the valves. ..engines with pistons that can hit valves as in my is the only way to fly................................The 3.6L Engine found in the Cadillac CTS, SRX, STS, and various other GM vehicles is a great engine. But they have issues with timing chains, needing replacement. ... This is an interference engine, and the repairs will probably double in price, if the engine can even still be saved. ... Oil is cheap, timing chains are not. Is this engine a non-interference engine .I dont believe so. The only engine GM ever made that was like that was in the old Saturn L300s with the 3.0L and if I remember right it was a DOHC engine. I think those are the only ones that are possible to be interference engines. this took me an hour .......
