If it is advanced to far, It will be hard to start when engine is hot and when it is running it will ping and rattle and could even burn a piston. The timing on that year should be set at ZERO at top dead center.
it has both chain and gears
the timing marks are not on crankgear on cam gear Chevy Lumina 3.1 1995 would it be keyway to keyway
That requires an engine scanner to set the timing on that engine. The timing is computer controled.
Chevy 350s have timing chains,not belts. It is designed for the life of the motor. If it is "streched" , the cam timing would be slightly off. Would need a degree wheel, a dial indicator and stock cam specs. intake/closing.
That means the timing chain and gears are worn out / to loose.
Yes, especially if the timing is overadvanced.
There's no timing belt, it's a chain, and those things are rated to like 500 000kms. I've seen impala taxis come in with 350 000kms on the clock, and the chain has never been replaced.
Why would you want to unhook the Electronic Spark Timing?
That would have a chain.
That engine doe's not have a timing BELT. It has a timing chain and gears. The chain and gears are about $60.00 the gasket is about $12.00 and the Labor would run about $150.00.
That engine don't have a timing belt. It has a chain and gears and it would crank over real easy/freely.
Not necessarily, but you will have to pull the timing cover off to see what's going on.
