BRAND NEW JEEP CHEROKEE LAREDO 4.0 0331 CYLINDER HEAD

Too low to display

In this two part episode we replace a casting 0331 cylinder head on Andrew's 2001 Jeep Cherokee 4.0L straight six engine. Part 2 is installation, this video may also come in handy if you are simply replacing the head gasket.

Personally, I would not be crazy about any welded 0331 cylinder head, professionally done or not. I've not heard of any success with any types of welding on this problem. The casting is thin there; yes you could probably get it welded and fixed (for now), but I don't think I'd sleep that well knowing that it could crack again in the future. I definitely would NOT go that route. Any new engine I'd be putting in would not sport an 0331 cylinder head, unless it's a TUPY.
