Engine noise!

[pbsupra90]

Just curious. I have a 1990 Supra Turbo. It runs beautifully and have had a lot of work done on it. It just seems to have a lot of engine noise in first gear. It gets quieter once you are in 3rd or 4th gear and on the highway. But initially it is quite noisy when I hit the gas. Is this normal in an old Supra? Car has 68,000 miles.

what kind of noise are we talking about? whining, grinding?

Ya what type of noise?
Fan noise?
Whineing?

 

[pbsupra90]

A combo of both. It's just sounds like the engine is working hard. Car has no problems with acceleration, stalls, anything.....just a bit noisy. It has been tuned. Perhaps sound deadening material might help. But hey....I don't think it's supposed to be that quiet. It's not a lexus.

exhaust leak off manifold or downpipe?

 

[pbsupra90]

I don't have that much technical knowledge. What is a downpipe. And how does exhaust leak cause such noise?

The fan clutch on a 7m can be very loud and higher speeds it doesn't get used so sounds kinda like that.

But a video would help.

You can tell if it's the fan clutch by starting the engine and with the hood up it will be loud for a bit and then it should quiten down. If it never does for the fan the clutch could be going out.
