'89 2.6 Exhaust Manifold

Postby SurferJoe » Sat Apr 15, 2017 1:09 am

This is the 4th time I've created a hole in the exhaust manifold, right on the inside of the casting, engine-side before the oxygen sensor. Anyone else have this problem?

I'm getting tired of buying new and used parts - I had one time where I welded a plate over the hole and it worked for a couple of years before it fell off.

Cast iron is tough to weld with all the silicon that rises to create a 'no-weld' zone.

Grey Works can ship me a new one if I go for it again.

Stock manifold is prone to cracking. Replace it with a header and forget about it.

I took the heat shield off of my manifold when I replaced it last time. No problems since then.
