Loss of power....HELP?

Aug 9th, 2002, 06:54 PM

My Nissan having a squeeling problem? I have since replaced: Plugs,wires,cap,rotor,fuel&air filter,BPT hose,BPT valve (valve before egr valve) nothing! Think maybe its the intake manifold making a squeaking sound? The belts are all new too (all three).
Wife says it has MAJOR loss in power going up a hill.

Squeeling in the manifold? Usually in the manifold it makes a ticking sounds when cracked or theres a leak............Sure it aint the front brakes? Ive been getting a sqeeeking sound in the front left area, and I just replaced my calipers and stuff..........................Dont know about the power loss, is it standard or auto?

It only squeals when high rpm's are given at idle or driving. It is a automatic. So brakes would be ruled out. The manifold gasket was replaced in the past and the sound is different. It has 85,000 original miles on it.

Im stumped too? I can ask other people I kno, if someone doesnt reply to u first....

Thanks a lot. My wife drives it to work, and I worry a lot. I am disabled, and can't be much help if she gets stranded.

Thanks again!

got a reply from someone, they said, Something with the timing belt has failed or slipped? (explaining loss of power...)

Interesting. I thought it couldn't slip due to the notches on the belt....
Thanks, will check into it.

heres another idea,,, (fan clutches can cause a squeal. Also idler pullys and adjuster pullys )

Aug 10th, 2002, 11:18 AM

All the pulley's move and I oiled them too

as for the fan clutch, not sure if it has one, I know the suburban does, as it was replaced.

Squeal is GONE! It was the flange gasket on the header (stock), but the loss of power is worse!!!!!!!

thats cool that its gone but add performance items for more HP.
-Muffler with dual ehuast 5-10% increase.
-new headers 15-20% increase.
-K&N air filter, tornado fuel saver, each around 2-3HP.
Right now I got all that except I'll have my Doug Thourley Headers on the 23! People told me to get a computer upgrade for all that performance to I dont know why but I guess to let out even more HP that the items are holding back but I guess its not worth $500................ See ya.

I have a 6cly. Im getting Doug Thourley's which everyone says are the best. I bought them for 341.00 from truckperformance.com . They are like 14 guage nickle chrome............................................ the other company that makes headers for nissan's are Pace Setter, but the suck. I tried buying headers from them but they would have any in stock till in like 5 months. But theres for my truck would be 199.00.

DesertBum, man I dont kno what to say,,,,, Just try one of the performance items and cant up some juice.......
