well since monday morning i heard my engine rattling. i thought it would stop but didn't. it rattles at start and whenever i hit 3000rpm. I think it is the timing chain or maybe something else what else can it be. if i need to change any of the timing chain parts would it be ok to use the same parts from another motor or just go ahead and get them new. anyways what can the problem be and what should i do?

So does it rattle faster when you accelerate?

timing chain tensioner? :confused

I get a rattle in my car when i'm around 2700 rpm. I'm thinking my heat shield that covers the exhaust manifold is cracked and rattling. If it's that i'd guess timing chain hitting the chain guides. Not sure though.

yeah it those but at 3000rpm it makes the noise and then it stops after 3000 or so. what i really want to know is replace it with new parts or use some from another motor. i say this because i have my old blown motor.

My car makes a "ticking" sound when idle but I can't here it when driving. But I know that it doesnt accelerate when I step on the accelerator.
My problem is my timing chain guide, yours might be similar but I don't think it's the timing chain guide IMO :dunno

When my tensioner grenaded it self, I would get a rattle that started as I dipped into the throttle from a stop, and last until about 3200RPM. Does it sound like a metal chain being drug across the floor? If so, timing chain tensioner or guide. Be warned: your car is a ticking time bomb now. Seems that as soon as the Rattle-o-Doom starts, you have about 3 months (on average) to fix it or the chain will eat through the head into the water jacket (what happened to my KA). I took the $1000+ that a shop would charge to fix the timing chain (8hr job for a shop with a lift and tools, 10-12 for a shade tree mechanic) and bought a CA18DET. ;)

Upper timing chain guide. Pop off your valve cover and do a quick check to eliminate that very likely possibility. Both of my goddamned KAs had the same problem, but it's perfectly fine without it.
