Dead cylinder?

[deankelly]

Hello all.

I have done a 98 expo 5.0 swap into my 96 ranger

I seem to have one dead cylinder and the plug is covered in a flaky crusty substance. Strangely enough, looking into the oil filler neck i see the same substance. Is it possible that i have a head gasket that is blown into an oil return galley?

Thanks for the help.

Possible but not very likely.
Cylinders are surrounded by water jackets and water passages in the head gasket area.
That's usually the first system effected by blown head gasket, cooling system.

What does the coolant look like?

Start engine and remove oil filler cap if you get alot of out flow then could what you think.

How does it run? A bad head gasket would have white smoke from the exhaust and or milky/ gross oil. It probably wouldn't run so great either. Whats that a picture of?

Probably runs like it has a dead cylinder. Guessing not well .

It may be accumulating fuel from not firing.
