Help on deciding on engine replace

So i picked up my 96 not running. When I got it going I started chasing down leaks and replacing some wonky repairs. So far I have a rebuilt turbo, resealed the fuel bowl, new lift pump, New Hpop o rings, new cps, new valve cover harnesses both side and a couple glow plugs that didnt ohm out and a air intake from riff raff. The guy i got the truck from was chasing a no start issues and spent about 2k on lpop, ipr and a few other things.

I have a rough idle until she warms up so im pretty sure the poppet valves are worn, has a lil smoke on idle and take off, ive done the filler cap for blow by and it doesn't move. Have not done a compression test yet. I am loosing oil slowly somewhere with no visible major leaks, and my hpop resi looses oil overnight but i cannot see a leak for it either. oil pressure gauge takes a few seconds to read but ive read that is normal. I have had several times the truck would start then die after a few seconds, but would crank up and stay running after. Truck runs great when warmed up and I have no issues with starting after it has been driven. I found a take out motor that is supposed to have 8 new injectors, new front cover, and water pump. Comes with everything but alternator and AC pump for 750. Said it ran great and was taken out because the truck was in a fire but engine wasnt hurt. Motor has 330k.

Question is should I just pull mine and swap in the take out and work from there? Or try and track down the issues with the motor that is in it and use parts from the take out? Im going to get the motor regardless as it seems like a good deal even if its just for parts. Looking for everyone's thoughts and what they would do if in this situation. Just looking to make the truck reliable, not looking to make crazy power.

Sounds like you just need new injectors. I say swap out the injectors from the new engine.

Re: Help on deciding on engine replace

When you have the valve covers off before you pull the injectors you can do a compression test, that will be the first step towards deciding if you need a new engine
Its the oil consumption has you thinking it needs help? Compression numbers will remove quesswork

Ya. It's the oil consumption that has me thinking. Trying to track down an adapter for the glow plugs. I know I can search it but does anyone have acceptable compression numbers handy?

Re: Help on deciding on engine replace

the hose for a grease gun works perfectly along with a harbor freight diesel compression tester

Re: Help on deciding on engine replace

Anything under 300 is getting pretty worn. 350+ is good. Post up some numbers when you get them.

Thank for the base number. Hopefully get to it this week. Finally got my obd2 adapter to connect and now I'm getting some interesting codes on all 8 cylinders after doing a buzz test.
