Please Help: Timing Belt / Tensioner Problem...


400m

Recommended Posts

So, yesterday afternoon my wife and I were exiting I 95, and at the end of the off- ramp, a terrible rattling, clanking noise started coming from the engine bay of her 2000 Prelude VTEC DOHC. we pulled over when we had a safe spot to stop and check it out, roughly two to three blocks. When I checked the oil, it was dry as a bone- But I knew that it should have had oil in it. So, I walked to a store and got oil, put it in the car, and started it- hoping that somehow ALL of the oil had been drained, and this would solve the noise. Not the case, as when the car was started, the noise continued, and then the engine died. On trying to start it after that, the engine just turned at a high rate, with no fire- as though it was out of timing. I checked the oil level after AAA got us to the house, and it was double what it should have been... I pulled the head cover this morning, and the timing belt is intact, but very loose, and when the engine is turned over a bit at a time, you can tug the belt and it will skip teeth. Now, when trying to start the engine, there is no terrible noise, I don't know if that is good or bad. It seems as though if something were crushed or broken, it would be getting kicked around somewhere in there, right? SO: what is the overall damage? Is this engine designed in a way that valves would be crushed if it were to jump timing? I know nothing about honda engines, as all of the vehicles that i have had have been 60's to 70's BMW's. Sorry for the long post... Austin

You definately need to replace the timing belt and tensioner. My guess is the tensioner went bad. Same thing happened to a friend of mine.

 

I don't know why you read the dipstick and it showed the car being empty, then after you added oil it was way over. You must have done something wrong.

 

Yes, it can be catastrophic to your motor if you skip too many teeth or snap your timing belt. Just change the belts and go from there. Hopefully you didn't f*ck anything up.

 

In the future, when you hear a horrible noise coming from your motor it is best not to keep on driving it, kinda like beating a dead horse.

Well, I have had the same type of thing happen with a Fiat that also was DOHC. The retarded timing causes an excessive vaccum, which will suck oil into the cylinders...

 

Hopefully, the next time I need to stop and gaze at that puzzling metal rod which reveals the level of oil, I won't be in an area where you can look to your left and right to see people smoking crack at three o' clock in the afternoon... "would you fellas be kind enough to keep an eye on my beautiful wife while I run down to the liquor store for some oil?"

I agree with not driving the car until it is fixed!

 

replace timing belt and clean the oil before driving it again! I don't think it would cause considerable damage to the car but I guess you will find out after driving it again...
