I don't have an actual problem at the moment. I just need to know a few things about the timing setup so I can know if I need to go ahead and do it.

First off, is this a chain or belt?

Second, what's the service interval?

Third, is this an interference engine or not?

Fourth, would you please attach instructions on changing the thing?

TIA.

This will be an easy one for you. This is a timing chain for this engine, so it only needs to be replaced if there is a reason to replace it. There are no maintenance intervals on chains.

However, if you need to replace this, I attached the process below on how to do this.

Please let us know what other questions you have.

Thanks

So, with it being a chain driven engine, is it not interference? That's what I'm worried about. I'm looking at putting it on the street some days for 9 to 12 hours. I don't mind if the chain breaks or slips, so long as I don't have to replace the engine due to smashed valves and pistons.

And this is just one more reason I prefer a Toyota over Honda. Yes, I know it's a "Chevy, " but we both know it's a Corolla. That's why I bought the thing. Chain instead of a belt. Cheaper to maintain and more reliable. Might produce 3hp less, but well worth it to me.

Understood. Looks like this engine is non-interference.

Let me know if you have more questions on this issue. We need to keep each to one topic so if you have other questions, we will need to get a new post started.

Thanks
