LLY Headgaskets/ studs and everything else I should replace...

[DieselDaze]

My apologies, I was playing baby semi truck driver that didn't like slowing down for hills. My avg trailer weight was 20-30,000lbs.
I cooked a few engines to death because of it. Basically you don't want sustained engine oil temp over 220-230° or you split pistons. Personally preferred 200-220 temp range while towing..
IDK what the L5P run for oil temp,
I know dirty hooker diesel has an L5P oil cooler swap package https://dirtyhookerdiesel.com/i-240...-cooler-assembly-2020-2021-repl-12701592.html

We can easily spend your paycheck 🫣

i have overheated the truck once upon a time and im hopeful my pistons are okay and this can be a straight forward job
