After a discussion with someone who’s sorting out an oil pressure problem in a 5.3 that may be sludge related, I decided to do an early oil change on mine just to have a look. I’m not having any oil pressure issues myself.

At just 1700 miles on the oil, it’s black as coal. That tells me there’s some built up deposits inside that are going into suspension. So, I’ll put her on a 1,000 mile oil change interval until the oil starts coming out clean. I’ve done this successfully before on older engines with sludge deposits.

This truck doesn’t have many miles, but it’s over 10k hours, so either a lot of low speed operating or idle time when it wore the uniform.

Tomorrow I’ll cut open the filter and if there’s anything noteworthy I’ll post a picture.

That's how my issue started.
I put seafoam in the oil as a cleaner, and it sure loosened the sludge up!
It got into my pump, low oil pressure, i believe it probably plugged my filter up as well.

With my engine apart, the best i can figure is i begun wiping out a cam bearing...


not being 100% and really wanting there to be a silver lining, i decided it's time to go 6.0.



I make questionable decisions.

Ouch. Yeah I have a low opinion of flushing in general. Maybe on an engine that’s already plugged up and there’s nothing to lose. As long as the sludge is adhered somewhere, it’s relatively harmless. Break a whole bunch loose at once and plug an oil passage- game over.

Fresh oil will dissolve it over time. As long as the engine operates fine, I take the slow and safe way to cleanliness.

Shell Rotella Diesel with a good fine filter works good .

What kind? PPV's or just regular stock?

So i decided i wanted to put a coat of engine primer on my new 6.0
then i saw the instructions said "within 10min next coats"
then "within 10min apply color coat"
then "Within 10min apply clear coat"
then "all coats within 1 hr"


Me: ffffffffff

Painted, and currently drying.
I think it will look much better once assembled.

Oh and i totally wore a respirator that makes all things smell like a hospital while painting that crud.
Luckily i had a fresh 3m mask!
