I have a 93 integra with a b20 vtec b18c1 head. Brand new timing belt and tensioner. Every time I set the timing it will run for about 5 minutes at idle then it will jump time on the exhaust side about 3 teeth. I have looked through the forum and done every thing people have said to do including using a coat hanger to hold tension and it still jumps time. Does any one know what could be wrong. It has a gsr timing belt water pump and oil pump. Please help?

 

ITs probably cause there to much slack in the belt if it jumps at idle. What is your procedure for tensioning the belt? make sure the belt is nice and tight with a 1/2'' deflection on both sides when set at TDC when tensioning the belt. as well as torque the tentioner bolt to spec. Im not 100% sure what timing belt and water pump is needed for that engine combo but you might have the wrong size timing belt causing the belt to skip from being to big and not getting enough tension.

Wasn't it GSR/ITR water pump has to get GSR/ITR timing belt, and LS water pump get LS timing belt

opp wunfstgsr linked it!

 

I lossesn the tinsionor bolt set the timing gears put the belt back on tun the engine counter clockwise three teath and tighten up the tensioner and put it back together

 

hows the slack on the belt on each side? when you rev the engine does the belt flop?

 

You go from sounding like this ...
And next reply looks like this?
Grab yourself a mirror and position it in front of you so that you see your face in the reflection. Thats the problem. There's no reason a belt jumps 3 teeth on the exhaust cam gear after 5 minutes of running at idle if you've followed procedures correctly and verified your setup. Plain and simple.

 

That was funny. But foreal OP, sometimes the tensioner spring gets old and won't tension properly. If there is still slack even after the proper procedures are taken, push the tensioner up a little but next time you're at three teeth past TDC and tighten. That should snug it up a bit.
