the $130 is AC delco 252-898

seems identical to the AC delco 252-383. and that ones like $70

so to be completely honest.. i don’t know. GM wants $350 for the pump and housing, plus another $20 for o ring.

seemed a bit much. and that’s after seeing what other dmax parts run

Danville Performance pinned AC delco is what I used on the LB7. Probably overkill since I've only heard of very high HP motors spinning an impeller but I'd still use AC Delco OEM. The labor to replace is way to high to to skimp on that part.

According to my parts house, the oem is 251-748...shop cost is $231...about what shop cost would be from dealer.

The 252 is the cheaper "Professional " series.

sounds great. will look into picking one up after i get the turbo back together

the piece that turned from rust to brown to black is the center section/bearing housing of a garrett GT3788VA turbo. it’s hard to see while in the truck since it’s jammed between the large aluminum compressor housing and the turbine housing (the piece in the oven when the pegs sticking out of the face)

it has oil and coolant fittings in it as well. it’s a jam packed little guy.. but really not that hard to do.

i took it down to every piece, which isn’t necessary for a service. but when i looked inside the VGT solenoid hole i was able to see a bit of gunk/oil residue inside. so.. it came apart for cleaning

swbhobie16 · « **Reply #458 on:** June 29, 2019, 11:09:45 AM »

bare housing, ceramic coated and baked

liberal coating of 2k° anti seize

VGT vanes

unison ring (light coating on back)

indexed to accept actuator arm

full extension

full retraction

another light coating on the bearing housing mating surface

anti seize

factory wheel is just there to hold place until the wicked wheel arrives. then the from of the housing will go on and deem the turbo complete until it goes on the engine

Where is all that AS going to go?

swbhobie16 · « **Reply #460 on:** June 29, 2019, 11:26:14 AM »

idk for sure. most likely right out the back. but some will stick around.

it’s the procedure found on duramax hub..

if it all goes away it won’t be any different than when i pulled it apart. hahah

rpar86 · « **Reply #461 on:** June 29, 2019, 11:35:57 AM »

Duh! I thought it looked like a turbo (especially since you were just pulling one apart), but the rust colored assy threw me. Never seen one all torn down like that - that must be the actuator for the vanes yeah?

I saw that too, doesn't it go through the motor first?

Also saw there was a SS ring for that. Never checked price. What about ceramic coatings?

no sir. it leaves from here and goes straight out the down pipe and back. it’s exhaust side, so post manifolds and uppipes. even if it still had EGR it wouldn’t be effected.

ceramic coating is a loose term. it’s bake on paint with ceramic in it

but it should still work.

the bearing housing is just professional krylon.. my figuring is that it has both oil and water running through it.. it doesnt get insanely hot. and if it does, ohh well. just needs to be pretty and black for the build pics

JR · « **Reply #464 on:** June 29, 2019, 12:02:43 PM »

Looks good. I doubt the oil is for anything but lube but sure the water helps.

swbhobie16 · « **Reply #465 on:** June 29, 2019, 12:22:20 PM »

my thoughts as well. should be ok..? it didn’t have anything on it before. so if it goes back to that.. ohh well. hahah.

can’t wait to get the compressor wheel and front housing on and call this one done!

I’d like to see some photos of the block where the charger rests before you put it back. Unless I am to late.

sounds good. i think the hardest parts are going to be uppipes and oil drain into engine/trans adapter. the coolant lines shouldn’t be hard either. they’re on the side of the bearing housing. but i haven’t seen the engine in a truck/know where or how it’s situated under the dash.

i’ll try and get as many pics of it when i goes back on.

alittle update on the duramax

got some color on it before i went out of town for 2 weeks. hopefully in that time the heads will be back on it and injectors/lines plumbed back up

original plan was to remove old upper and lower oil pans and swap out but after getting color on this one.. i think it will suffice. just have to finish up underneath when i pick it up (literally) and then pull lower pan off and replace gasket/pan (possibly).

should look pretty slick when i get it back. new (refreshed) heads that are fully cleaned. rocker boxes cleaned, valve covers cleaned, intakes and y bridge all back to aluminum. rebuilt turbo with high temp paint on housing, exhaust manifolds, uppipes and a new 3” magnaflow downpipe.

really liking the drivetrain color.. even though the block will be hard to see buried under intake, IC piping, AC tube hoses, cooling lines, power steering pump and belt! haha

JR · « **Reply #476 on:** July 12, 2019, 06:10:07 PM »

Looks good. Does someone make a better pan that would allow full oil draining?

i think PPE, mag and pan make some. may look in to that. help will cooling too. and a few extra quart capacity

JR · « **Reply #478 on:** July 12, 2019, 06:44:39 PM »

Does the topkick or other formats use the same pan?

Can't believe they really designed it so it holds like 1/2 quart when drained. Dmax is such a great all around truck, just so many little things could be better!

swbhobie16 · « **Reply #479 on:** July 21, 2019, 10:28:50 PM »

i honestly don’t know about the pan on the 4500+ models. but you’re right.. seems odd they’d do that. i’d love an aluminum pan to add a quart and the ability to drain it all out.

swbhobie16 · « **Reply #480 on:** August 07, 2019, 06:11:12 PM »

couple of things happened today

‘assembled’ the heads/rocker boxes/valve covers today for a quick look see

they had been blasted by machine shop and i really like the look of raw aluminum.

so..

before

after

ARP studs and head gaskets should be here tomorrow. which means i may can get the heads back on and valves adjusted in the afternoon.

time will tell.
