Man, stupid me! all this damn time i thought its was the intercooler-pipings not connected correctly and that i may have a blow turbo or maybe the maf and that's why my car won't fired up. Didn't have time to look at it until last nite due to my busy job.

Anyway, i back-step and re-checked all of my wiring, sensor and power and its seen to be fine. And so, my last resource is to check on the timing belt, and what do you know.....stupid a$$ timing belt broke! Dammit! but luckily its broke on my driveway so i don't think there's any major problems to the engine and valves.

ugh...RB's are interference engines. sitting still you can still bust valves. you need to replace the belt and do a compression test ASAP!!!!

yeah, you are right kanim. guess i will check on the compression asap, but if i try to turn the engine to check the compression won't it will damage the valves?

negative. if you set all the pulleys to thier correct timing mark positions you'll have no problems. Also when reattaching the belt ensure you rotate the motor over twice before tightening down the tensioner pulley. it's in the fsm. do not over tighten the tensioner pulley! it will tighten by itself so where ever it sets bolt it in.

did you replace the timing belt before it went in? if not then your motor is a poster child for everyone to replace their belt before something like that happens.

yes, the belt is new. i am so piss that i decided not to go to work today so i can take a good look at it. what's happen was somehow one of the nut fell inside the timing belt housing and caused the belt to break. i check the crank pulley and it still turned over good. i am trying to test on the valves right now to see if it ok.

Ok, just check on the valves (old school's way by turning the camshaft) and it rotated smoothly with no noise inside the valve cover. So that's a good sign. anybody happen to have an extra timing belt?

wtf are you talking about

with no timing belt you could have just bent a valve if the piston was at TDC.

you need to replace the timing belt and do a compression test. DO NOT ROTATE THE ENGINE OR CAMSHAFTS WITH NO BELT

Dammit kamin! why did you say so earlier! now i have a bent valve! Just kidding my lil bro just came over and take a look at it since he's a mechanic tech, and he say that everything is still ok lucky for me. but he say the same damn thing.....just leave it alone for now and do the damn timing belt before touching anything else!

I had the car for sale on ebay for now, but if i can't sell it then i will do the timing belt and continue on finishing up on the damn A/T wiring. Don't give me wrong. I luv my s14 and the RB. It's just because i am so frustrated on the wiring for the A/T and the damn electrical techs around here couldn't even help me on that! then there's my job where i am pretty much busy all the time....and then offcourse there's my old man, he keep on bitching about the car taking up the space and how stupid i was...just wasting lot of $$$ and the car still doesn't run! AAAAHHHHH!!!!
