Question compression test question

hi

the engine i bought came today and looks quite nasty; looks way worse then my dusted engine with 250k on it.

the donor engine , e series, has quite a lot of caked oil under and around lower part of cover. this leads me to believe that this engine had been severely neglected. paint under valve cover is flaking due to long period of immersion in oil

before i send it back, i would like to do a compression test. the engine is on a pallet but looks like i cannot use a starter to turn it over.

can i turn it over by hand?

Also, since i have a single AD injector and this engine has none installed, can i simply use the single injector one cyl at a time testing as i move inj from one cyl to the other?

I would think a leakdown test would be in order. If you can't use a starter, you can't really do a compression test.
I don't even know if you can do a leakdown on a diesel.

Is it low mileage? Do you have a turbo with it?

Its extreamly hard to clean a van motor when its in it... There is just not alot of room to get a washer wand in there. Would you rather they pressure washed it and hid the dirt?

I think your over thinking this...

Mileage on the motor?

HI I hope so... slept maybe 2 hrs last night mulling this over. Mileage is reported to be 120k..and from a '99 e series. I think the valve cover leaks were from someone replacing injectors or glow plugs and because of the tight space, didnt get the v-covers down good. I was told the van was last use for recreation - towing 4 wheelers and such, that the dust and oil met up and made grease. I ordered a compression gauge and powerstroke adapter yesterday and will test engine next week. There is no turbo or hpop...nor injectors. No biggie as all of my stuff works fine.

knock on wood, but mine looks like shiat, but runs great....anyhow, your best bet IS to find a motor, when looking for one, thats still in a truck/van..etc
