Timing Belt Change- Problems - Honda Prelude Forum

Help!!

I just got through changing my timing belt, balancer belt, water pump. The orig belt snapped on me last week, but I was going fairly slow and hoped there wasn't big damage to the valves.

Anyways, all together now, won't start. Cranks, but sounds like it is out of time. I followed the Helms instructions pretty close, is there any differences if the belt has blown (ie not a regular change)? Maybe a different alignment of the cams?

Also if I did mess up my valves, would it cause these symptoms? I assumed it would start and maybe just run bad or rough.

Thanks
Paul

PS Sorry about the cross post... my bad.

well you set everything to TDC before you put on the timing belt so if you did that is should be fine. you put the punches in the cam shaft and pins in the balancer shafts(those wouldnt have anything to do with the car not starting though), and obviously the crank at tdc.

Yeah, did all that, turned the crank with a ratchet afterwards, seemed OK, belt a little loose between the cams but nothing to fret over.

what engine? u using a manual tensioner or autotensioner?

93 Lude, 2.3. It has the manual tensioner in it. The belts seemed to go on right, but the timing belt was tight and tough to get on. The tensioners didn't move much for either.

I remember when I did mine that the belt seemed to be loser feeling then it should have between the cam gears but after I ran the car and took off the valve cover to check it again. It was back to being nice and tight.

yeah when i did my h23 belt, it was kind of difficult to get on. some times it felt a little too loose on there, and sometimes i thought it would snap again.

i know that the flywheel has two white marks, one for a timing gun and one for the belt which confused me. there is a possibility that you got the white marks confused

ir perhaps your valves are screwed like what happened to me

Sounds like the valves to me, this happened on my old Si. I replaced the t-belt, water pump, tensioner hoping that the valves were OK after the belt snapped. The car cranked twice and started but it was a REALLY, REALLY rough idle. I removed the head and took it to the shop, end story: 6 bent valves. Cost $225 for the shop to replace the valves and resurface the head and a new gasket set. Reinstalled everything ran great. Took about a week for everthing, mostly b/c I had to wait on the shop. Good luck
