for some reason my timing keeps skipping at the crank gear for some reason. ive reset it twice and have replaced the belt. the tensioner is as tight as it can go. i have no idea where to go next.

 

The gears do wear. Did you inspect both the crank gear and the cam gear? How's the waterpump?

If you keep going on the motor you will kill it.

When you set the tensioner did you do it by the book and turn the crank a little to move the slack so the tensioner would be set correctly?

 

I would recommend you replace the tensioner. If you say it's as tight as it can go and it still slips its no longer any good.

 

Or you have the wrong belt.

 

what block, what head?

 

it's a stock B20 and im pretty sure i have the right belt, i got it from autozone. i followed the steps in the CRX B16 shop manual but i didn't put slack so the tensioner would set properly, it didn't say anything about it in there. but it may be the tensioner... it still tightens though, just not enough...

 

Yeah does sound like a tensioner problem get a new one

 

so i re-did my timing and tightened the tensioner down all the way and the belt still has quite a bit of slack. ive also rotated it at a couple of different positions to see if it can get any tighter, and it won't.

should i replace the entire tensioner? or just the spring, because a whole new set up will run me next to $100 off of majestic. and a spring is just $3.

here's the link to majestic for a B16 del sol

Sounds like a GSR belt on a LS/B20. How many teeth? 125 or 126?

 

Use an OEM belt, how many teeth on the water pump?

 

Have you tried to manually tension it instead of relying on the spring?

ive only tightened the tensioner bolt, how would i "manually" tighten it?

 

Look at the picture up above. #21 is the tensioner bolt. When you loosen that, it means the tensioner pulley can move up & down. The spring should pull it upwards, but you can use a coathanger or something to help the spring. Pull upwards to make the belt tight, then lock the pulley in place by tightening the bolt.

ALSO: Check #13.. Make sure the tensioner is sitting on that dowle.

thanks for the good idea

 

did you reinstall (not in the picture) the washer that goes under the lower timing cover. its a wierd looking washer. what it does is it holds the timing belt against the motor. if you forgot to put that on then the timing belt will start to skip teeth.
if you are missing that washer you will have to tear it all apart

 

it is the wrong belt! I had the same exact problem with autozone. they sold me the belt i installed it, and it was to long. i took it back had them look up a timingbelt for a ls came up same part #. so i bought a oem honda timingbelt(like you should)
took it into autozone, had them cross ref the honda timingbelt # and it brought up a totally diff # lol. autozone

you mean this one?

 

That dished washer holds the belt from walking off the sprocket. Depending on the year of your engine you may have 2 of those (#13) on both sides of the crankshaft sprocket (#17). Or other years you'll have a #12 sprocket with only one dished washer.


Missing that washer shouldn't make the belt loose. But it will allow it to slide outwards, so the belt starts rubbing against the timing cover.

Is the belt still loose?
Verify that your tensioner pulley is positioned correctly.
Verify that you have the right waterpump (how many teeth?)
Verify that you have the correct belt (how long - how many teeth?)

holy crap...i think this is what is causing my idle problems and timing to be off about 5-6 degrees...fawk!!!

it all makes sense now...off 1 tooth...timing erradic...and misfires...you my friend are a genius...

 

that looks right

 

set timing with tensioner loose; rotate motor over 3 teeth; then tighten the belt. Been doin it this way for YEARS
