Since the engine is somewhat tilted backward I pulled the foreward most plug on each head, on the drivers side it happened to be the icp and manually filled the heads with oil. Started the first crank and has been fine since! Since the icp is higher up air accumulates right there giving it faulty readings and it might take alot of cranking for it to see the 4-500 minimum to start with air right underneath it

I did that same thing one timer Muk. Mine cranked up the first time also. Here lately I just use the starter though. Lazy I guess.

Thanks,

There are a couple hex head plugs on each head, they point up and inward at an angle. I don't remember the size hex, but maybe 16-17mm or so if I remember right. When you crank the starter, the hpop pushes fluid into the oil passages in the heads toward the injectors. When there is air in there, it's compressable and takes forever to build pressure. If you crack the plugs after cranking it will vent the air to the atmosphere. You'll hear it hiss air and the oil move. Top off the hpop again and repeat till you get oil from the plugs instead of air.
