D100 1/2 ton drove 120 Km/HR home. Next day drove a few feet and truck stopped moving. sensors: A/C relay (33), 14 MAP, 13 MAP and 12 (battery disconnect). Engine burning oil which is enough to fog yard in about five minutes.

Truck has a small coolant leak in No. Eight cylinder. Spark plug fouled. All sparkplugs had soot around igniter cone except No. Eight which had oil. Compression none on cylinders tested.

Got a friend to tow truck to garage. I was able to drive truck under its own power up car ramps. And down again and into garage. My next step is leak down test

if it won't move under its own power first place to start is transmissions fluid level. make sure it is where it needs to be with the truck running in neutral. i usually cycle though the gears before putting it in neutral and checking the fluid level. if that doesn't fix it then there is likely something worse going on.

The leak detector revealed a blown head gasket between intake and exhaust pushrod, of No. Eight cylinder. Cylinder PSI revealed 150 to 160 range for cylinders One to Seven. Only 40 PSI No. Eight cylinder.

Cause of coolant and oil in No. Eight cylinder was wrong size cylinder head bolt purchased and installed while previous one went missing, it was during disassembly.
