I have a 1990 Chevy Lumina Euro with a 3.1 liter. I was wondering if there is a need for timing chain replacement. The chain does not make any noise, but the car now has 240,000 miles on it. Just wondering?

Depending what kind of engine you have, a timing belt breaking can either instantly shut down your car (which is at best inconvenient, at worst potentially deadly), or it can destroy your engine.
I had a timing belt break on me as I was halfway across a busy road. Fortunately I had a non-interference engine, meaning the car just shut down, the engine wasn't damaged. But it was pure luck that there wasn't traffic coming that could have killed me. I had just enough momentum to pull into the safety lane.
You can have someone look at it and see if it appears to be in OK shape. If it looks OK, and you have a non-interference engine, you MAY choose to let it go and take your chances. But if you ask me you should just replace them according to the manufacturer's schedule and not take a chance.

I'm pretty sure the chevy 3.1 V6 uses a chain driven camshaft. Unlike a timing belt, it doesn't need regular replacement. I wouldn't go into it unless it jumps. The engine is likely near the end of its service life anyway. The whole engine (not just the chain) is likely wearing out.

The 3.1 is an awesome engine,especially for longevity! Put a timing chain on it ,surely, but if you can afford it install a new cam. You'll see a dramatic improvement and get some more life out of the car.

the situation some timing chain is that that's much less costly and provides no warning while it shall we circulate. in case you're fortunate it particularly is going to bounce time once you shut the engine off and you will no no longer something till you circulate out and attempt to crank the engine. it particularly is going to spin like a precise and could no longer crank. in case you're unlucky, the chain will bounce while the engine is working and particularly lots smash the whole valve practice and probably even a piston or 2. I understand they are made greater helpful at the instant yet once you fee your mechanic's intelligence and he says it particularly is time to alter the timing chain, i might do it. in case you come to a decision to realize this and circulate out to get interior the van and take it to him and it won't crank, a minimum of admit I advised you so. No, the chain would not wreck. It wears so undesirable it jumps over the tooth on the timing gears and subsequently gets out of time. perhaps so badly that it's going to no longer even turn the camshaft anymore.

I wouldn't change it. The whole car is only days away from falling apart anyway and there is no way to know what will break first, just be sure something will...any minute now. (I'm not being mean--although I know it sound like it, it's just that you are close to the useful life of this product--and way beyond the average life span for it)
