When I bought this Ford, the PO was told it had a possible cracked head. 4.0 OHV 210k. I bought it with my eyes open.
Usually every morning upon startup, it will misfire for a moment--maybe 20 seconds or so then it smooths out. Usually after starting, by the time you get out of the front seat, back to the exhaust you can feel a smooth flow.
It has lately become more noticeable and upon startup even after sitting for only an hour or so, I did find early on #6 was wet in the morning with coolant.
I assume--the PO tech (who turned out to be a smog guy) is right. It may have a cracked head. Someone also suggested that it is a head gasket. Now yesterday just prior to breaking the door handle on the drivers' side, it was also suggested that the intake manifold is leaking at #6.
Since I mainly am an OHC owner (have 6 now) and have been having a whole lotta fun this summer yanking motors out to do chains and guides, this 94 was a fluke buy. Price was right ($400), PO has spent a whole lotta money on new parts, such as Transmission, tires, brakes, radiator, AC and so on. Then she gave up.
I have put 4500 miles on it, with the misfire each morning. Now that it is getting worse, what to do,
1. Have shop pull and replace the intake manifold?
2. Headbaskets?
3. Swap in used heads? (Rebuilt heads locally are upwards to $900 plus install.)
4 Low mile used motor off a site such as Ebay (LKQ)
Those of you diehards that own the 1st Gens advise me.
215k, uses no oil or if it does it is sooooo minimal.
