Can "Like New" Exhaust Manifold Gasket be Reused?
I have an '89 Toyota Pickup w/ 22RE engine. About a year ago, I rebuilt the
exhaust system, including replacing the cast iron exhaust manifold with
header pipes. At that time, I replaced the exhaust manifold gasket with a
new one.
I am now doing an R&R on the transmission which requires unbolting the
exhaust headers. I figured I'd once again have to replace the exhaust
manifold gasket with a new one. However, after pulling the old one, it
appears to be in perfect shape. It did not stick to either the head or the
headers so no surface material was damaged on the gasket. In fact, there is
little to no discoloration of the gasket material and, except for some light
carbon powder on the exposed port surfaces and a light imprint from the
mating surfaces, it's virtually indistinguishable from a new gasket.
After spending over $900 on a rebuilt tranny, plus $100 for a new clutch,
plus other incidental expenses associated with this job, I'm not keen on
spending another $40 on a new gasket if the old one can be reused. What do
you think?
Thanks,
Michael
