Thought I blew a head gasket or cracked a head. I have aproxamitly 1qt of oil in my coolent, but no oil in water? I did a compression test 1-4 dry 175, 165 ,110, 100, this is too wide a spread . 1-4 wet 135,135,135,110 , this is more like it. This is my first wet dry comparison . I thought the numbers were only suposed to go up? By a lot as in 3 for bad rings. With each compression stroke on 2and 3 the water /oil mix pulsed out a cupple Oz each time. 1and 4 no such pulse just jiggle from cranking.
I have a recently acquired 87 Ram D50 2.6 Smog. Mt 4x4. Has new radator and water pump. Pulled the head assumeing blowen gasket. I see some strange markes in 2, 3
Markes at 9 and 7.

(cant see 1,4 on tdc) they look like lightning bolts going partway down the cylinders a frend has some " spot check" penetrating die test. RED LINE NEXT TO the squiggle is the crack. Ding dong the witch is dead . Not worth sleeving +compleet rebuild+ new /reman head. Sleebe + head => long block.


Theas vertical scoring(deep enough to catch a fingernail) weren't cracks ,however there was a crack in #2 adjacent to the score mark.

I had planed a weber swap. Thats happening as well as a long block .
I would realy like to know what happened.

All freeze/ soft plugs are in place and old. Truck had a bad thermastat
stuck 3/8" open

had to block 1/2 the radator to keep it at the 2nd mark on the stock gage. 95% blocked @+20°f =middle of the gage. For the madin voyage 405mi home with my new winter rig. Then dorve to portland, Oregon and 3 days later it wets the bed. Oily water on the driveway. I wanted to have more than 5 tank base line before modds(3 with liget thermastat) . But life is.
