HELP is '93 Corolla 1.6 interference engine?

Hello, new to the forum today...

I cannot find a straight answer to this question...is my 1993 Corolla with DOHC 16 valve EFI 1.6 an interference motor?

From what I have found, the SOHC 8-valve 1.6 in the previous generation was a NON-interference engine...and that when it was redesigned and put into the 1993-97 generation Corolla/Prizm, it became an interference engine. Other places online swear my engine is a non-interference engine, though.

So, I came here to get a straight answer...

I am 10K miles past the timing belt change interval already and am trying to figure out if it is worth changing the belt ($300+) on a 14 year old car with close to 200K on it. If it is a non-interference engine, I will just let it go and if it breaks, I get towed home and have it fixed. I am not sure if I want to take this chance with an interference engine.

Thanks in advance for your help.

It's non-interference according to the Gates Belts Catalog.

That is a lousy way to treat your engine. If you change the belt yourself, it will only cost you about $12.00.

Thanks for letting me know about it being a non-interference engine...

The only reason I will let it go until it breaks is that there will be no harm. Perhaps it will never break. Fact is the car has 200K miles on it and I just discovered today that the CV joint boots are shredded. That's money I have to spend on this 14 year old car, but the timing belt is not.

I just don't want to spend the money on a car of this age unless I have to.

As for changing it myself, I was looking under the hood while changing the oil and it doesn't look like something I want to attempt. I have had bad experiences when attempting repairs on my own!

Change the belt. A belt change cost the same as one car payment. It will break at the worst time. You will have a towing change, a possible rental, and a missed appointment.

How much does it cost to have a timing belt changed? (mainly interested in hours of labor as the part is cheap)

Preventive Maintenance is always beneficial. There are lots of ppl that know how to do timing belts. Have any friends or neighbors that know how? They probably wont charge you if you ask them to show you how instead of asking to do it for you. Its fairly simple if you follow the steps in the repair manual or watch someone else do it once. You will save a ton of money if you take some time and research it, and your car will probably last a long time if you change the way you think about it. Good Luck

It is what I paid in the past. I am in Texas so prices are lower then the rest of the country.

Why GUESS as to whether it needs to be changed or not? It takes all of ten minutes to loosen the valve cover, remove the top timing belt cover, rotate the engine and check the entire belt for cracks, frayed edges or other issues. It all depends on the quality of the belt and your driving conditions on whether it will last 60,000 miles or 260,00 miles.
