The front exhaust manifold on my 2002 Ford Escape is warped. The problem is the catalytic converter is integrated into the exhaust manifold so a new one is like $800 and you can't get them at either of the junk yards I go to.
I don't have the time or money to take it to a machine shop.
Are there any tricks I can use to get it fixed good enough to get back on the road?
Examples I thought of:
Use two gaskets on left and right cylinders but one gasket on middle cylinder
Coat the gasket in high temp manifold cement sort of like how you use RTV.
high grit sandpaper and some kind of custom rig to keep everything at right angles + a lot of manual labor to even it out.
