#2 primed .

Same issue of air lock on the filter head again. This time I pulled the oil temp sensor and set a cup under it. Took a couple 10 sec cranks with glow plug deletes out to get it flowing. Then reinstalled the sensor and she built pressure like normal.
Gonna have to note that one in the owners manual..

I put never seize on the last set of glow plugs I did. I've heard some complain of the lack of conductibility, but I say BS. Would rather have them come out in one piece

I put never seize on every glow plug I've ever done. Never had any issues with continuity. Though it's particularly irrelevant for these motors LOL

I've heard horror stories on glow plugs from many professionals. And judging by these SS deletes, don't really think I'd want to torque on a real plug that hard..

But be sparing because any excess does run down the stem to where the plug seals against the head. Noted that on a couple that hadn't been out since dyno.

Funally got Stbd side fired up last weekend. All looks well on both engines and trans, so can mount the turbos up for good this time.

If you ever wanta build your own LBZ/LMM harness from scratch, please hit me up, and I'll talk ya outa that stupid idea.. I have all the ECM pins and connector numbers, even source for the secondary locks. Which I used up outa every factory harness on the property. I was only missing the Bosch machine used to assemble em. An important tool, unless you've installed several hundered DSP5 switches in a single month... lol

Seriously, it about whipped me, and like wiring work. But they are done now and since started on front accessory plate half of the job.. FUN FUN!!

Also Vibrant sells some junk.....

First failure I witnessed was one of their turbo band clamps explode on a friend's boat at only 50psi. Wrote it off defective part.

Then had a 6AN cooling line end fail on the dyno. Probably over tightened it, ok.

Last, fired up the second engine, 6AN turbo feed line is leaking at the block off cap. It's a swivel end, and no sign of damage, just leaks...

Replaced it with a Fragola while on the engine. Since that's straight off a mainline to the block, was worried about trash from end swap getting into the system. Luckily an empty tea bottle make a nice catch can. Crank to purge line, reinstall block off cap, problem solved..

Like that Mobil1, reasonable cold pressure now. And those anti-drainback filters fixed the dry fire issue. Makes 25lbs pressure on second revolution. Hits over 50psi before they fire :-)

Time to finish up the front end.

I learned on the dyno, these things will still chuck a 6 rib belt just as quick as an old vee setup. Hope I get it right this time.. Then buy two new alternators and reclock the back half so pos terminal isn't tuck out in the wind...

Without it, the rubber hose connections would fail pretty much every time under the heat/pressure of the charged air.

I did actually farm it out. Then spent a couple days fixing pins on it. Said I can do this next one better myself.

Soon discovered I'd just as soon let someone else do it, so I at least have someone to bitch at when it doesn't work...

And I fixed one of his in FL last year. lol

Actually his work isn't to bad. Was just some LBZ to LMM pin differences. Same type setup I've done for a couple boats in the past. Where you use the oem engine harness and bale connectors, and just modify the chassis harness and fuse block.

I on the other hand thought it be cleaner to only used the engine connector leads and ditched the bale connectors. Well jury still out on that one..
