This truck is starting to get me upset. I have posted a couple threads and done some research and started dismantling the truck.
'95 PSD 5 speed. 174,XXX with the turbo, UVCH and outside wiring, 2 inj. changed in 2 years/15,000 miles. No chip or tuner EBPV brake used, 120 volt, 3 year old IDM.

Truck was used plowing snow 2 weeks ago, another guy driving but I never noticed problems while next to it running. Next morning started truck, lots of smoke, missing and definite injector knock sound, no whoosh sound at that time. Removed valve covers looking for whatever, this was AFTER A/E said passed buzz test and when warm at operating temp the smoke disappeared and it passed contribution test. Unplugging inj. found no change with #3 inj. all other inj. the engine noticeably missed worse with disconnecting each. Rigged up 120 volt pilot light as noid light and it flashed on all cyl.s the same. Unplugged/plugged up #3 and it started firing??? Did buzz test again and #3 and #8 High to low side out.

During all this truck starting making whoosh sound never stopped smoking just for grins I performed compression test cold and thought I would retest when warm. During all this I found that 4 out of 8 glow plugs bad, replaced and started and the whoosh sound is REAL loud now and unplugging the EBPV does nothing to affect it.

Compression cold was between 290-340 all 8. Truck is really not bad shape and I feel the comp. isn't bad for cold, but I'm seriously thinking C4.

I could really use suggestions and would really appreciate all comments.

 

Can you look at the actuator rod on the EBPV and tell if it is closed. It could be stuck closed.

 

Well, first I believe this is several problems, maybe unrelated. (electrical etc.) I have removed the turbo and before that I could not tell that the rod moved, however when I disconnected the down pipe the butterfly valve was OPEN??? That has me wondering what is going on. The whoosh sound and the terrible smoke. I took this same turbo off and reinstalled a few weeks back because of oil leak and after making sure everything was clean and tight, no more oil leak. I ran the truck hard, towing, Interstate speeds, exhaust brake use etc. NO problems till this other driver pushed snow. I'm thinking after telling him to turn it off he did not and he could have sat with foot on brake for extended periods. But, again, the valve was open when I removed the pipe and I had someone else start it while I watched, never saw rod move. Now the sounds and smoke, terrible smoke. When engaging the switch for exhaust brake the sound never changes.
