To all that put in in to this posting...

THANK YOU!!!!

We finally got her running late last night, changed out pump for spare. ran rack new air cleaner. run great again!!! You guys here are the greatest!

you have a real strange problem here alright!

I still beleive you got a timing or pump problem!Just by your discription of what happened at the start!

To check the timing set the engine on valves rocking on #6( valves closed on #No 1 )pull the engine up to apox 30 degrees on the flywheel or damper pointer marks.remove #1 delivery valve with 11/4 1 5/16 or 1 3/8 12 point wrench on the big nut on take it out remove the spring and valve and reinstall the nut just snug .get some hose to fit the inlet fitting hook it on and blow into the tube fuel / air will flow from #no one keep blowing and have somone slowly turn the engine till the flow stops right where the flow stops is where it is timed.BE sure that the fuel stop is full on and the throtle is at idle for this!

this will rule out the timing thing I got in my brain anyway!

The bearings in the fuel pump may be on their way out causeing the timing to be all over the place.

For the symtoms you have I would suspect to see it at near zero for timing ,the engine should be at somwhere between 15 - 24

Back to the shop again hope this works

I have another pump that came with truck all the delivery valves are out of are the as easy changing 123? if so i will throw that pump in

thanks again

Worn exhaust valve guide(s).

One time I pulled the valve covers off an ENDT676 and the exhaust valve guides were so bad there was gritty soot type material all over the place in there.

Great those we can deal with i was afraid we had lost a piston or something!?!

Motor has great compression but the soot now makes since.

thank you

Back in the "80"s Michelob had a great ad with a Phil Collins song(tonight tonight). There was a black convertible with a good looking woman sitting up in the back, followed by two black Superliners bob tailing....very cool,Tim

Well here we go again...

Pulled pump and coupler is fine. with pressure gauge on fuel line out of fuel filters before injection pump have 35 psi , with line put back on pump and cranking i get fuel out of #6 valve only in small spurts. if i unbolt fuel pump from injection pump and crank over seems to pump fuel out all valves and seem to be alot more???? very confused starting to think C-4 and walk away!

also any thoughts on really sooty oil in # three rocker arm area?

Have you checked the turbo and the air cleaner plumbing for birds nests?

remove the air intake from the inlet manifold and try to start it! IF that don,t do it then,

I got a feeling your pump drive coupling may have broken and its now out of time.

You have smoke that tells me you ar getting some fuel, and no air Or poorly timed fuel.

I have seen the drive couplings break Usually its clean and wont turn the pump but it may be ragged enough to turn the pump in ths case.

Ok Had air intake lines off last go around leaning toward pump coupling if so what and how do i go about putting her back in time. Going to try and remove pump tonight but not sure if i should but engine in time first?!?

Thanks for all you help I do have spare pump for parts

AMBAC for sure then. Thanks alot!!

Try to get her fired today and all i got was thick gray smoke like an old wood burner so thick it made the shop as dark as night.

All the tags are missing off pump not sure which pump is which any way to tell?

Direct fuel no filters no progress

thanks guys for help

I would by pass the primary filter and run from a clean

pail of fuel Also remove and check the secondary filter for poor fuel quality.Also

If this truck is equiped with a tack drive mounted transfer pump they were a pain!

Heading back to shop to try these tips , will post udates thanks

no engine brake

Hello all new here! from what i have read this site seems to the most knowledgeable site out here!!

On to the problem...

I bought a 81 RS 600 2v 350 twin stick, Truck ran great got it home drove it a few times and it seem to start miss firing then blowing white/gray smoke. smell of raw diesel fuel and died Can restart with Starter fluid and it idles really fast no more miss firing but is just dumping in fuel.

I thought it might be a lost injection tip, pulled all 6 all looked fine checked rack and valves all look to be it order.

I did notice that in the valve train there appears to be a lot of soot in the oil between 2&3 cylinder and only there?!?

Any help would be great

Was hoping to let wife pull truck in upcoming truck pull
