Re: Noisy engine, cracked exhaust? '90 Celica

I looked in my Chilton's manual about removing/installing the exhaust
manifold and gasket. Is it really as simple as unbolting the old one
and placing a new gasket on there and then bolting it back on? Is there
any risk in doing this? Could I lose some of the bolts? I tried to
unbolt the bottom exhaust manifold bolts to try and replace some
gaskets but was unable to get the bolts to move. Any recommendations
for getting the bolts to move?

I searched the group and was reading some interesting posts about my
"loud" engine. After some searching, I have come to believe that my
exhaust manifold is cracked. I removed the heat shield that sits over
the exhaust manifold and noticed several cracks on a metal piece that
sits between the exhaust manifold and my engine (I am assuming this
would be the exaust manifold gasket).

How serious is this issue? I have driven the vehicle for about 3,000
miles with the crack and haven't noticed any severe issues. My primary
reason for repairing this is that I am not exactly a fan of the
lawnmower ripper-sound coming from my engine compartment.

The car probably will not pass an emissions test with an exhaust leak before
the catalytic converter.

There is some dange of the exhaust fumes being sucked into the passenger
compartment.

I live in Michigan. Does anyone have an approximate idea on how much a
shop may charge me to have the work done?

Thanks.


If you are capable of removing the heat shield, you are capable of removing
the exhaust manifold and replacing the gasket. The job should cost under
$100 if you pay someone.
