isx15 cm2250,enginee 2012, enginee lock up

[Vanhvacr]

Hi Al.,.
I have a 2013 freightliner cascadia with isx15 enginee cm2250 is at 689k. At first it showed low oil pressure at around 3k miles oil changed, then check enginee light on, engine protector on, derated, and then shut off engine. I had to restart the truck. It repeated itself one in a while for atleast three time for 900 miles. I got oil pump changed, and she is up to 36psi, kinna ok but not perfect as 42psi, at 1317rpm at 74mph.

After a few trips, she started getting weak with up hill, 3%, and oil leak from turbo. I gave her a new turbo to boost her up. Now the oil pressure is coming back to hunt me. Low oil pressure on, 16 psi and lower at normal freeway speed, check enginee light on, enginee off in the middle of the road on I20 back to Atl. I got lucky, and we drive safety to the side of the road.

No more juice left, not crank, nothing, nihil.. engine lock up. Cost $1970 from Tuscaloosa, Ala to Atl one way trip without her pony.

Turbo and air to air charge have oils, exhaust manifold white soot, coolant normal, oil normal, crankshaft not spind with a 3/4 ratchet extra long.


Any advise will be helpful,

Thanks you,
please pardon my broken language.
