So many lines! What do they all do?
« Reply #30 on: February 22, 2016, 06:59:49 PM »
Thanks for that info about what could be lying inside. I'm a diesel mechanic at a tractor shop, mostly I work on industrial equipment, I've just never messed with these gm diesels until now. I did work on semis for about 5 years and I'm familiar with the big straight 6's.  I have a injector tester at work, I do want to check them after I'm sure my fuel supply to the ip is as good as it can be!. I pulled that filter housing from above the axle this evening, plan to take it to work tomorrow to clean it in the parts washer, may send it to a friend with a hot tank

Replace the oiled gauze air filter with the AC Delco paper A1300C air filter that GM used in the K47 air boxes.  Ideally you want to find a GM K47 airbox and ducting to the turbo from a 1997-2000 GMT400 CK 2500 & 3500. 
The CDR will plumb in correctly.
You'll get noticeably better boost.
You'll get a filter condition indicator.  Not that important but kinda cool.
You'll get a lot less dirt in the turbo and engine than the "High Performance" filter.

I am searching for one of those air boxes on a budget, but worse case I plan on using a break and making my own air box mounted on the passenger fender

If you have the flexible duct that ran from the elbow to the turbo you can Fab an airbox to fit the Delco A1300C filter.

Several other engines used this same box and filter with different ducting.  The 6.5L specific piece is the elbow.  Some guys on the dieselpage forums made a replacement for the discontinued K47 diesel airbox  elbow with an ABS black pipe elbow.

The filter housing is in pretty sorry shape, black goo inside the thing and most of the ports were plugged up, I had it in the parts washer all day and put it in carb dip before I left work this evening, are there replacement parts for the housing?

I mounted this aux  fuel water separator temporarily on the inner fender. Once the 6.5 housing is in I will put the aux one in place of my old 80 unit.

I cleaned up the 6.5 housing today at work and head blasted it and it turned out really nice except in between the two center tubes where the screen goes, there's some gunk down in there that I couldn't get out with the carb dip, parts washer, brake clean, or compressed air.... I soaked the housing again over night and will check it tomorrow. If I can't get that part clean then I'm going to have to bite the bullet and buy another. Probably won't be able to drive the truck around until this weekend, but I'm hoping this will cure my water issues. I'm draining the filters each time I run it until I'm sure I've had no more issues.

3" or 3.5" ABS street elbow to fit the Delco 1300 filter.  Read this thread.  http://www.dieselplace.com/forum/63-gm-diesel-engines/21-6-5l-diesel-engine/596202-how-big-hole-k47-filter-5.html

PVC elbow battery post rubs. http://www.dieselplace.com/forum/63-gm-diesel-engines/21-6-5l-diesel-engine/363978-just-received-my-k47-did-i-get-what-i-paid.html

No reason to get a factory airbox.  Fab one to fit the filter and go.

Nothing wrong with spin on filters as a primary.

if your handy with a welder, cut open the vacuum canister(leave the bottom portion that connects to the support/turbo),  weld a 1/4" all-thread rod, on, and go to a hardware store get a couple springs (about 3 inches in length) of varying compression strengths) then use a lock nut and some finishing washers(the concave/convex washers that tend to go on decorative furniture.) test it out, ideally about 10psi is perfect for full throttle, 2-4 psi for cruise, anything more tends to need studs, and better headgaskets

the other option is pretty much the same as above, but you need to figure out a mount and a way to attach it to the wastegate lever

here is mine(GM-8 turbo, vertical wastegate) I haven't had a chance to completely test it, but pretty much followed other peoples ideas, and the general concept of a mechanical wastegate


Current Vehicles:1985 GMC K10(Daily) 1991 GMC K2500(Daily) 1975 Beetle(not running) 1985 Mercedes 300D(not running) 1952 M35    1967 M715(not running)
 1986 Chevy K30(under repair)

Cool looks simple enough, and I do almost all of the welding jobs at my work
