Finally Pics and a vid in this post. I have Good and Bad news... Good news is truck is running! I think we were dealing with fuel/air leaks (maybe a pocket in that new IP too). You can see a video of the truck running here:


Bad news is I took out for an extended drive today and there clearly are some issues. First thing you'll notice is a lot of smoke. I am thinking this is because it sat for 2 months...? After driving a bit it cleared up some, but is WAY more smoky than my 300TD (which barely smokes at all). Any ideas how to clear up smoke? Or just drive a tank through it maybe?

The big bad news is lack of power. On the freeway it did 55 mph and didn't want to do more. I am thinking this has to do with lack of fuel. I know what a 617 can do and it just seemed like something is wrong, not that I was maxing the engine.

I brought the truck back to the mechanic. Our next idea is for him to take out the in tank Dakota pump (not being used now) and install an inline fuel pump with metal hose drawing up from the bottom of the tank. Any other ideas?

 

The engine does not sound too bad. It could be just a worn out engine, is it making boost? any intake leaks???? compression test, boost and EGT gauge, blow by at the breather?? or you still have fuel problems, NO need for a boost pump in the tank if you have no restrictions in the lines. It might not do much better, She might not have any more to give, MB's are pretty doggy, and I am driving a NA engine. for the smoke, If you have not cleaned the injectors I had very good results with the Seafoam hot soak method, Did you ever change the fuel filter???? or do a valve adjustment?

 

Ok so fuel pump is now out of the tank with a new line run with 8psi inline pump. Truck is running well but SMOKING a lot.... We think it might be a bad injector giving the engine too much fuel. Hence the smoke and the hard starting (not too bad but cranks longer than normal).

Or the ALDA ?

compression is good, valves adjusted, both filters new, oil change... Here's a link to latest video, any ideas what to try next?

 

hot soak sea foam treatment, if that does not help then look for a bad injector

 

are you still driving the om617 Dakota ?

are you running a manual or auto behind it?
where did you outsource the adapter plate and motor monts? any interference problems with cross members. or oil pan?
tx.

 

You can see that in the beginning of the thread he said he picked it up already put together.

 

that still doesn't answer the other questions!
manual, auto?
still running or dead in the oil?
oil pan interference ?
I am interested in knowing whether the auto trany needed a stand alone computer, a kick down cable, etc..

 

If he is running the stock trans, then yes he would have to figure out some sort of stand alone computer. If you want to have an auto then I would suggest the AW4 that came in the XJ Cherokee. They have their own computer and you can get an adapter to fit.
