replace the fuel line with the crack ... drive and report

 

If it was a air intrusion in one of the fuel lines wouldn't be hard to get her to start up again?When it dies on me it fires right back up?!

 

yes air make it very hard starting.

fuel heater screen clear?
i forget what is the fuel pressure?

 

if it were on the suction side it would make a sputter though .. especially @ higher rmp ...

 

I have no idea what the fuel pressure is but i just replaced the lift pump and deleted the fuel heater and cleaned the pre filter but im have a guy advance the timing for me and see if that fixes it

 

Careful unless u have studs .... Don't go more that 17-18 until u get et studded up... Blown HG is a real buzz kill ...

 

I've read up and 16-16.5* sounds pretty safeIm not tryin to make a race truck or anything just a truck that I can race some gasser and diesels for fun and not get my a** handed to me

 

Hmmmm, I predict a headgasket failure coming soon...........please stand by.

 

Yeah ... Me too ...


its not the timing alone that will blow a HG ... High drive pressure,timing,fuel,and boost combine to create a high cylinder pressure and also higher cylinder temps can vaporize. Coolant on the top of the cylinders inside the head causing spikes in coolant pressure ..... Add this all up ... Pop goes the HG .... While studs are never a guarantee... It a great way to have assurance that ist not gonna be immediate... Ask me how I learned all that ... ?
