Ive' had long cranking when cold for a few years now. I decided to replace the Fuel pump and removed the push rod for inspection and look what i found ! The Wear is on cam shaft end. I will install my spare rod and hope for some results.
I’ve seen firsthand some bad ones but has to be the worst and I’m not talking about the length so much as how that end looks. All the ones I’ve had wear out were still worn square and not angled like that.
