Im having some issues revving 500rpm before cutoff. Everytime I wind up, I hear a "SHHHHHH" sound from the timing belt side. It sounds like something is vibrating. No power loss. I have NO heat shields either.

Valves are properly adjusted, compression check is okay.

Somebody had told me it might be the harmonics from the timing belt. The belt has approx 70K on it. Is it time for a new belt. BTW this sound has been going on for the past 30k miles.

TIA

i had that problem with my mustang gt car is ****

and it had the same problem , i sprayed in between the belt and the gear with some "belt lubrication" while the engine was on
and the sound went away.

 

Anybody else have feedback on this?

 

70K miles!
Change that bad boy ASAP, especially if you're exercising the car.

Have you checked the belt tension or deflection?

Havent.... a mechanic informed me of buying a new tensioner, water pump, etc. Is he shooting me straight?

 

pretty straight...
might as well replaced those things when you replace the timing belt
everything is located right there...saves you labor charges

 

I put a new tensioner on at 85K miles just for peace of mind when I changed the timing belt.

If the water pump isn't leaking then I wouldn't change it (I didn't and it was still fine @ 125K a couple weeks ago).

Better safe than sorry, especially when goofing off.

 

once it gets time to change your timing belt when your getting close to 100k ...its a good idea to get a new tensioner ...water pump ..etc .......and yes ....change that belt

 

Do that tuneup Better safe than sorry man.
