Sorry to hear, couple q's to help understand.

What type of oil you running, sythetic? How long on the oil change interval?

What type of veg system (DIY, vegistroke, GFS)? Some info on your switchover process, i.e how long purge/run cycle?

You obviously have a ton of veg miles on the truck but that may have nothing to do with it.

Can you isolate which cylinder is washing down with a contribution test (if the covers are back on)? Someone with more experience will chime in, but cracked injector?

reply wvo in engine oil

i switchover to diesel on way to and from destination or if i forget to switchover i let truck run for 5 to 10 minutes
my system is diy, heated tank heated filter and head and fphe
my switchover system has a delay relay and pressure sensor on veg pump (wvo designs)and a delay relay on diesel pump (fass) so both pumps run (pressure, delay)on switchover
i did find injector that was bad, had a broken intensifier piston
how much wvo does it take to gel oil? im going to do a test on that
ive pulled all injectors and taken them apart and cleaned them
i change my oil every 3k religiously 15/40 Rotella
ive changed oil twice and run truck about 100 miles each time since finding sludge in oil
thanks for the reply

Fantastic that it happened where you didn't drive a bunch with the veg mixed in. I suppose there is no way to know when that is going to happen.

Did you snap any pics of the 150k veggie injectors before cleaning? Much buildup?

Is she back to running good after the short oil changes?

If I had to guess, I'd say this injector was your culprit.

I this was my engine I would run some Archoil AR2300 with a fresh oil change. It might take a couple times to clean things up but I think it is probably the best option for getting that crap cleaned up inside the engine. AND I'd run it in Rotella T6 5w40 synthetic oil which will also help clean the engine out.

AR2300 nano engine cleaner removes all deposits for a more powerful and energy saving engine - Archoil

call me nuts ... just do it now and get it over with but I will share the "trick" I learned several years ago taught by an old school wrench.

To get the goop out, drain what you can and top off the crank case with diesel. Crank it. If it fires up, let it run! Shut it down and drain it all out. Then refill with mostly diesel and a quart of marvel mystery oil. Crank it again ... if it runs, let it run no more than 5 minutes. Shut it down and drain. You ought to get all the old sludge and goop out of the engine. Fill with cheap oil and drive 50 miles. Drain that out and replace with Rotella and a new filter and you will have cleaned it out.

Why not, right? At this point of the game, what do you got to lose.

I read that in Japan they run cars over 2 years old with BioD in the Crankcase to clean out deposits and then drain it.
Same idea I guess
