I am new to this site, and I am glad I've found it. I had gotten off of the hiway and was going down a cty rd and the truck lost power. as I coasted to a stop I smelled hot engine oil and tried to start it but no start. towed it home and decided I had lost oil press in the hpop probably due to a line. tore it down and I did find some damage to one line. replaced both lines all four ports they go into, both fuel lines to the heads, all the o-rings on the fuel filter housing, the fuel filter, and filled the hpop res with oil. tried to start and cranks but won't start. do I have to bleed the hpop system?
