We just finished a timing belt change due to it breaking on my friends car

We changed the head and put all good valves in and now after its done there is almost no low end power?!?
Could this be due to the timing being off or is there other factors that could cause this?

thanks

timing may be off,valve lash specs may be too tight/loose..

well when we first started it, it started right up but the valves were ticking a lot so we did a valve adjustment and now everything is right in spec.

 

its not right on spec if u did the adjustment while the motor was hot,it has to be completely cooled for an accurate valve adjustment..

well we didnt do it right away

we let the car cool off over night and did it in the mornig so i dont think thats the problem but thanks for the advice

 

still I'd check them again you might have not tighten'd enough and they might have knocked loose again. also check your power steering pump and stuff because they are also known to come loose at times..

 

Your timing is off. Something was not lined up when you put the new belt on.

 

well im getting a timing light hopefully tomorow so ill let you know how it goes

It sounds like your cam timing is off. Check & fix that first, before you do spark timing.

 

if you're off a tooth on the timing belt the car will run, but it will run like crap. which may be the case here.

Ok cool didnt get a chance to do either today but hopefully tomorrow I'll check the cam timing and the spark timing
thanks for your help and ill let you know how it works out

 

ya its your timing

 

still havent seen my friend since but Im defenitly going to make sure the timing belt is on properlly first then if it is then im gonna check the ignition timing cause right now he has it advanced all the way cause he didnt have a timing light and he said it ran the best like that

Thanks for the help so far

On my friend's H22 swap in his del Sol, the exhaust cam was off about a tooth, and the car had NO pickup at all. He fixed it last weekend and immediately it got ALOT faster.
