My injector pump started leaking badly one day, that's the only thing that's happened aside from general maintenance items in the 4 years I've had my 81.
That's an expensive rebuild ($1400) , but it's all viton seals and with the new fuel lines I could run veggy/100% bio now.

Lets see:
New OEM CT26. Original blew and impellar shrapnel went in to #6 cylinder, leading to.......... full engine rebuild (060 Oversized pistons).......new injectors......rebuilt fuel pump.......etc, etc.

Took me 6 months to get her back on the road. At the time, a major whore-deal. I'm kinda proud I did it myself (except machining) and getting to know my engine......uh.....intimately.

They guys at ATEB also had a client that his harmonic balancer fail too! Not sure what the cost was on that, but saw the damage it could do.

No major stuff on my HDJ81 except PM... replaced valve cover seal...

FWIW, I did do diesel purge and exhaust pretty clean @ 3k-4k RPM.

Chevron Delo 400 5W-40 Synthetic year round.

My dads rig has been running on it also for about 100 000kms now. He hasn't changed the BEB's yet either (knock on wood)

been warning my customers to check into this BEFORE dropping a dime on a RHD. many i never hear back from and a few only to say thanks for the warning.
how about a RHD to LHD conversion? a LOT of work, donor rig needed or do a engine swap into a US 80?

Rotella t 15w/40 is what I ran in the last truck.
I am switching over to 10w/30 rotella t in the next few days.
Amsoil everywhere else... Going to give their high moly grease a try.
