O/T Engine a bit too new but I need an answer.

I'll make this brief & hope to not get in too much trouble.
Is there any chance that a Honda "Interference Engine" can loose a timing belt & not end up with a head full of Bent Valves? Anybody ever have one that did not??
My go to work car lost the timing belt tonight -- it's not broken but the cam is not turning so , I assume it lost some teeth or stretched enough to jump off the lower gear. I hate the thought of going thru the head.

Thanks

 

The old 2.0 Accords. Put many T-belts on those and didn't havce a problem. 1.5's, 1.6's, 2.2's - they've always bent valves for me.

 

Things are not looking too good for you Im afraid

 

I am afraid you are probably right. Rats!!!

 

Since the T Belt is broken you could:

Pull the valve cover and then pull the cam. This would close all the valves.

Yank the spark plugs.

Run a leakdown test on all cylinders. A compression test won't do much since the intake valves will be closed all of the time... it won't suck in any air to compress.

If you have a cylinder that is way lower than the rest, listen to the intake or exhaust while doing the leakdown test and see if you hear a hissing, that could be a bent valve. This is good info to have... you will only need to replace the bent valves... not all of them. IE... if you hear a hiss in the intake while testing cylinder number three, you probably have a bent intake valve on that cylinder.

I have seen some interference motors not bend valves... just a freaky deal where the valve timing was perfect for not hitting anything. This doesn't happen very often, usually it gets at least two.

If you don't want to try that... put a new timing belt on it and see how it runs. You will probably have one or two dead cylinders. You could then run a compression test but it won't tell you if its intake or exhaust. Sometimes the valve is bent to such a small degree its impossible to determine unless you do a leakdown test or yank the valve and check it.

HTH...

Thanks , Tomo.

Thats very good information to have & is exactly what I will do---
probably not before next week end. Right now I have to figure out how to get back & forth --- my days are 15 hrs long as it is -- anything but driving is out of the question. Guess I'll either rent a car or buy a cheap ride to use till I get this back up.
