Found the problem. Lack of head gasket between 5 and 6 cylinders

It has minimal blow by. No worse then the first day I got the truck. Coolant system is not being pressurized. No oil or coolant mixing. It is huffing out the intake so it sounds like compression is being forced back into intake. Could be a bad valve or the head or head gasket. I’ll pull it...

I removed the valve cover and all the springs are good. I bared the motor over and they all feel about the same as far as lash goes nothing sloppy or to tight. I ordered the head gasket set. So I’ll see what things look like when I get it apart. This truck gets used a lot in the farm. I...

I replaced the head and all the parts to go with it. It acted the same with the old head and the new one

So my compression tester didn’t quite work it leaked past the threads were the injector nozzle would of sealed it. I took the lines of if 5 and 6. Then hooked them up so I could watch the injector lbs spray. They both adomized real nice I swapped them from 5 and 6 and the spray was the same...

With it running it smokes white blue. It is not using coolant

I’ll Play with line more today. It always smoked black. I bypassed the fuel density regulator and it gets good boost. There is fuel there but didn’t seem like it sprays out like the other cylinders

THanks I’ll fill you in on my progress

Well I’ll find out tomorrow when I test it. I guess I should start looking for a headset

It did seam like there wasn’t as much fuel got g to the number 5 injector. It’s been a year since I worked on it last. But changing the rotors head made no difference. I Took it apart and cleaned it first. I wonder if the head gasket is blown out between two cylinders or an oil galley...

The coolant and oil aren’t mixing.

Yes. A good amount of blow by. It does push oil out of the front head gasket under a heavy load. It smokes like **** but it always has. It is worse cause of the skipping. I just made a compression tester out of the old injector so I’ll test it to see if it can’t fire cause it has no...

Help. My m35a2 with the Hercules multifuel is skipping badly. I replaced the fuel filters and made sure the electric fuel pump is working and there is plenty of fuel going to the injection pump. I cracked the injector lines and it seamed like number 5 cylinder was dead. So I replaced that...
