So after I start my truck up, I can press the accelerator and it will squeal really loud, But once It has been running for a few minutes it will quit doing it.. It dones't just happen on the inital start up, it does it ever time i start it through out the day. The truck has a New Water Pump, New Timing chain, and New Timing Chain Cover, and two new belts, I noticed after I put a load on the truck, JL audio 12, Amp, and foglights it would produce a slight squealing at idle, SO i tightened up the alt. belt and got rid of that problem but it still squeals on all start ups. BTW the truck does not have power steering... ANY SUGGESTIONS?

The other problem I am having is a tapping sound (soulds like a valve, or an exhaust manifold leak)... Before I got the truck the Timing chain had broke on the previous owner.. So im thinking maybe one of my valves is bent? That noise its towards the firewall side of the engine.. Any suggestions on what to do with this problem? Should I go get the valves adjusted and see if that helps, anybody know how much that cost? Or should I check the E.M. first to make sure its not leaking?

You didn't spray anything on your belts by chance? Engine bay dressing or armour-all could contribute to belt slippage when cold. As the belts warm up the material becomes more pliable and the noise goes away. Maybe loosen one belt at a time on a cold engine and see if the noise goes away. It's cheap troubleshooting in any event.

As far as the tap, I had the valves on my prelude done by Honda and is cost $140 for a twin cam. I would think the truck valvetrain would be cheaper. It actually looks fairly easy to do in the driveway with the online manual, though I admit I haven't done it yet...

Good luck with the troubleshooting.

Hey thanks for the ideas, but it doesnt just happen when its cold.. The truck can be on I can turn it off and back on and it will do it again... I havent gotten anything on the belts, they are fairly new too that is what gets me..

I think I can do the valves but i got to get a manual first

with the truck idling, hold a bar of soap on the alternator belt.

 

[ocb_dave_ocb]

ok i will give that a try tomorrow.

if your trucks valves are ok and its efi then it might be the injectors, they are rather loud when they get older. I have the same problem with my truck sometimes the belts squeak or become loose.

 

[subliminaltrips]

yea rogerman is right the injectors are rather loud. also could be a pinhole exhaust leak but most likely its your injectors. as for your belt check to see which belt it is and tighten it up a bit. belt dressing also helps and dish soap can help, the tensioners are easy to adjust. carefull not to overtighten your belts as trix said.

I already did the belts, there tight, I think it is just somethin im gonna have to live with... What do you all think about some injector cleaner? or should i look into new injectors

 

[subliminaltrips]

all injectors will have a tick in them but if you have a tick it could also be an exhaust leak, lifters ,or the timing chain guide if its a plastic guide could have broken already. if you remove your valve cover you can check the valve lash and you can look down into the timing cover to inspect the guide. ive also know distributors to be noisy when they are new and when they get a little war in them. with your belts mave sure they arent TOO TIGHT. you may have a water pump going bad as well as the a/c compressor ,p/s pump or alternator bearings worn dry.

Indeed like Sub said, if the belts are too tight, it will cause A LOT of noise. Try loosening them up a tiny bit then see if it still does it.

Well the exhaust, lifters may be a possibility.. The Timing Chain is new, and the water pump is new.. The distributor is a possibility too, Im gonna do a tune up after christmas, The a/c compressor is a possibility.. P/S pump isnt a possibilty dont have it.. The alt bearings is possibile too, when i put my system in I noticed it was pulling the lights down, but now the system is gone, I have no clue as to why its loud..lol

 

[kimygoat]

Have ALL of your belts tightened. That was just happening to me, my mechanic tightened all of my belts and not the problem is completely gone.

 

[ocb_dave_ocb]

It actually quite doing it when I took my system out and took my fog lights off, I think i was just putting to much of a load on my alternator...
