Timing

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 .......

do you you understand my mess?

The LY7 3.6L is not an interference engine.

hi rowfast..i snuak it in up above you.........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,

According to Gates, it is not an interference engine. But, and there is a but...if the timing chain breaks it will cause a lot of damage.

Is a GM 2.8 3.1 v6 timing chain an interference engine? I think yes!

Well, It seems That it's up in the air.,.interference or not interference,, This is the Question?

The 2011 3.6 is definitely an interference engine I’m working on one right now and with the piston at TDC you turn the cam and the valves hit the piston!

I have had to rebuild multiple 3.6L engines they are definitely interference engines. Many Bent valves
