Not yet. It cranks fast now with new starter, almost feels like its gonna catch, but no cigar.

Bled air out of system down to injectors, glow system works, batteries are strong.

almost sounds like wrong timing when cranking.

Lots of blowby out oil filler neck, and crankase valve in front of turbo.

removed intake manifold and am extending PMD harness and moving another PMD out of the engine room

don't know how to take compression check? Or how to check timing

Doesnt look good

Compression tester screws into glow plug holes.

Will a standard compression tester work? Or will he need a special one cause 6.5s are one of the higher compression engines?

harbour freight sells a diesel compression tester with the adapter to put in the glow plug holes fairly reasonable,or perhaps a loan a tool program?

400psi is the minimum compression allowable.

Pulled all glow plugs, gonna get new ones and compression tester at HF

thanks for hanging in there guys

intake manifold and all accessories on front of the motor are off so I can sort this out







I am running two massive 900cca marine optimas, and sandblasted cable ends

Tried firing it up like this and no go.

Its not bad, if I can get it started I will clean it up and keep it, if not gonna sell it as a project

Undercarriage is clean and rust free but hard fuel lines are wet and probably leaking so I am gonna bypass with new 3/8 hose

Is it four wheel drive? Is there such a thing as a 2wd Tahoe?
