Holy christ, if not for bad luck I'd have none at all. So I bought a motor off of craigslist for this car because I found what I was told to be a slant with 2000 miles on it. Bought it, they just got the car started and its running on 5 cylinders. FML is there any honest people left in this world?

comp test the weak hole and see how bad it is.

A lil secret about the slant six is that the manifolds can warp and cause leaks at the gasket which can lead to lean cylinders that over heat and burnt exhaust valves. Maybe it just has a burnt valve.

Get a leak down tester from harbor freight and just do a leak down test as well as an initial comp test to see how many lbs it cranks.
