If the plugs are oil soaked, it's not firing
If they are oil soaked suddenly, and there is a clunking sound while running, you probably broke some rings Oil pressure changes would be a seperate issue. Could be something is plugging up the pick up screen

well i got it tore down and found head gasket blown between 3 and 4 cyl. and gasket was eroded back clear to the return hole on the head where the oil drains back down from the head to the crankcase. sent head off and they found nearly every valve seat was cracked, someone before me must have gotton this thing really hot. just sent another head off. have checked block and it seems ok. hopefully in another week the ranger will be back on the road.

Looking at your pictures. I love the old late 50's emblem on the hood of the ranger.

yes, i love that emblem, had been trying to find one of those for awhile now. found that one at a flea market some 30 miles from me, this guy had all sorts of emblems for sale, think he must have went to a junkyard and stripped as many as he could. id love to somehow emboss the tail gate with F O R D like they did back in the day. sure i could use decals but i like the "stamped" look better. ive already removed the blue oval from the tailgate and filled in the alignment holes.

heres the heads, top one is the original one that head gasket blew on, lower head is the one i got last week from a junkyard. both are 60# paperweights. think im going with a autozone head, can get one with valves but no cam/lifters for 350. a complete head with cam, valves,lifters and such is 532. think i have enough other peices that will work. just bites that "estimated delevery time" is dec 28. dont feel like taking chances with another junkyard head. just hope this isnt a china casting. they dont call it "the land of almost right" for nothing....

well, pulled the trigger on a new autozone head, the $350 one with no cam/lifters/rockers. just a head with valves in it, got my other peices i'll need soaking in diesel, cleaned with gas first but wanted a diesel coating for a little lubrication. head is supposed to be in saterday, guess we'll see, i was able to get my money back on that junkyard head that turned out to have cracks.

You're lucky to get a refund. All my "salvage" buys have been "as is where is".

well, got a refurbished head with valves in it, (2.3 I-4) went to put it on and discovered i have no alignment dowls, you know-those small peices that go in the head, the head gasket fits over them to align it, and when you put the head on the head bolts go through them. theres 2 of them they go on left side of block, look like thin wall pipe but theres a split in them like a roll pin, and usually they get damaged/destroyed rmoving them. well i damaged mine by using vise grips, figured i get new ones in the gasket set, no big deal.... well when i opened up my gasket set i didnt get those parts, went to autozone and it looks like i should have, and it looks like thats the only way to get them.... so i could wait another 3 days or so.... or go with this idea i just had. since you use new head bolts when re-assembling, i have a whole set of used original bolts. i took the best 2, cut the heads offf where the socket would go, then used the grinder to make a scewdriver slot. i can just finger those in the block a few turns, put on gasket then head, then regular bolts in a few holes before backing out my "alignment studs" with a scewdriver. havent done any more than make those pins, but i dont see why it wouldnt work......
