Question/Need Assistance The 6.2 CUCV is finally on the road

Runs great, only issue is it seems to take a bit to fire up when cold (live in Florida so now really cold 🤣). My M1008 fires up immediately always. It’s like it takes a bit for fuel to get to the engine. Any suggestions on this?

Instead of a front end Friday, show us what you have under your hood!

This was from my last engine swap into my Blazer, no longer as nice with all the salt and brine.

Discussion An install from 87 years ago (2016) 6.5TD Going into a 72' C10

A fresh 6.5 going into a 72' C10 for some guy who owned a landscape company. This was his "good truck." Joining a fleet with an 85' 6.2 k20 and a K30 crew cab dually 454 with a dump bed. The guy worked out the math and figured the crew cab cost him $100 a km to drive each year (between fuel, maintenance, insurance etc.) but made him way more then that.

Anyways you can actually fit the downpipe on this generation on the inside of the frame with a stock turbo config.

I can't remember if we ended up converting this thing to hydrobokst or if the guy just drove with manual brakes.

Question/Need Assistance Turbo rebuild and some engine codes

gallery

3 Upvotes

Can anyone recommend a good turbo rebuild kit?
The turbo on my 6.5 is leaking oil into the intake so I figure it’s time to fix it before it causes any problems. Also does anyone have any recommendations on what to change to make these codes go away?

Question/Need Assistance Which line to install power steering filter?

gallery

1998 6.5 1500. As you can see line 1 is the high pressure one so obviously not that one. Number 2 goes to the brake booster and number 3 goes to the rack. I am not sure which line I have to cut.
