No power, black smoke...I have checked turbo boost and have less then 5 lbs. New turbo about 1 year old. Removed air tube from turbo to manifold and have very little air coming out of turbo, no pressure. Turbo spins but doesn't whistle with muffler off.
Any suggestions?

check intake manifold for any plugs that may have fallen out. could be exhaust manifold plug fell out, or cracked manifold of even blown gasket for intake or exhaust manifolds. Take air cleaner pipe off inlet of turbo, make sure nothing restricting airflow there. Come on all of a sudden? Starts and runs fine? good luck, Ed.

Disconnect the rubber hose at the turbo that goes over the top of the radiator and try another boost test or remove both air filters and try it for a quick test. No change, then you must have a bad turbo or a blown intake manifold gasket... also make sure the 1/4" pipe plug under the turbo isn't missing and all three plugs( two 1/4" pipe and one much larger plug) are installed on the side of the intercooler and the top square plate has 4 tight bolts holding it to the top of intercooler. You don't say how suddenly this happened.

I would check your fuel delivery, not enough fuel will not produce boost. A lot of people think boost is built from just air flow through the turbo hot section. Flow is only a small part of the equation, to really build boost you need heat, and expansion, to get the latter you need a hot fuel mix in the combustion cycle, sounds like if all fittings are tight, your combustion is cold, either not enough fuel or really bad compression, I would bank on the fuel delivery. Check your fuel filters first, change them if you haven't in a while, then look at the pump.
Since you say you have no smoke, it sounds like the intake side of things is clear, but the guys are right, check it anyway, do you have a vacuum guage, see if there is a large vacuum pre turbo on the intake side, should be a little, but not much.

I took the muffler off , unhooked theair claener tube, checked the exhaust manifold and checked the intake side. It starts and runs ok. I put a new turbo on it about 2 years ago and it leaked in less than 1 year. took it off and had it redone and now there is oil in the turbo output side. 35 years allis tractors and the first turbo.

5 lb of boost would be about righr if it is running wide open with no load.
With cross over off, put hand over turbo outlet and open engine wide open. Should have enough pressure to almost push hand off of outlet.
Make sure nothing is pluging inlet to air cleaner. MACK

He says no power, black smoke. Anyway, sounds like another turbo is a great possibility, especially if there is oil in the compressor outlet. I can supply you one. pm me. Ed.

Sorry I read that as no power, and no black smoke!

Took the turbo to have checked...all ok with Turbo. Going to check the oil return line and check the intake manifold gasket.
