i just got my engine back together after studding the head,thicker hg,mac plu,60lbs valve springs,4gsk,new tq. I drove the truck about 5 miles drove and ran like a freakin dream. But i was doing like 60mph and rolled the throttle and the truck built boost and took off like a rocket. But thin there was pop, and back fire in the middle of the run and the engine died, now all it does is barely crank over and dumbs white smoke like crazy,wont idle either. I checked and could see my timing jump and is way off but how the could the timing jump,and the injection pump bolt is tighter than hell, still is even after timeing jump, i dont know why or how the timing could change.

 

If there was any dirt, oil or grease anywhere on that surface of the pump shaft or gear , no matter how tight you get it it will slip. it needs to be perfectly clean.

 

correct both the pump shaft and gear must be clean before there put back on. take it back off clean and retime

 

yup .. mine did it @ idle ... it went retarded about 12* .... Lotts of smoke ..

There is a product .. I cant find it right now ... for anti slip shaft treatnemts .. just for tapered shafts ... I will see if I can locate a thread on it ..

 

cleaned it, and got it retimed running good now again, but has like a hase of grey or white as if i got oil or something in the exhaust

 

Oil would be bluesh/white and greysh/white is compressed unburnt fuel, black is unburnt fuel.

 

Low fuel pressure could cause that as well ..but until the engine is warmed up .. Expect that you will see some haze .. mine does it as well .. and t runs awesome and it hae's when its cold until it warms up ...

 

It cleared up one it got all warmed up, just not use to the new engine and the differents with it, thank you guys
