Hx35/ht3b compounds issues help!!!

[cummins12club]

I've pretty much finished up my compound build utelizing hx35 over ht3b started it for the first time tonight and walked around to check for leaks and noticed a slight leak around the hot pipe and then saw that my ht3b isn't spinning at all! I freaked out and sthi the truck down immediately it only ran for about 30 seconds all the oil feed and drain lines r fine what could be wrong? Only thing I did forget to forbid tighten up all the housing bolts on the front housing please help!

Can you spin it with your fingers when it's just chilling there? There's a chance the housing was binding up the compressor wheel or something like that. Not a big deal.

Yea u could spin it by hand I was told by some ppl that it won't move untill it gets enough exhaust air moving to spin it and once it starts spinning it won't stop but ill let u know again tonight

[cmann250]

An HT3B was designed to be spun by exhaust gasses from an 855 ci engine, not a puny 359 ci engine If it spins freely and there's no exhaust leaks, I say you're golden.

Please do share about how it runs I like these old Holset set-ups

Sure will I pretty much had it all together last night but funny me forgot to put both bolts back in the top charger oil drain line and it leaked like a siv should have it buttoned up tonight how long should I drive around to break my ht3b in?

[cummins12club]

Got the leak fixed and everything buttoned up bottom charger spins at idle let it idle till warm up everything seems good to go I didn't drive it yet cause it was late last night and raining but anyhow I'm curious how long I should drive it and break the turbo in

[skilletky]

Backing it out of the garage should be a good enough break in.

Back when I bought a new HX35 hybrid from PDR, their instruction was to put 50 easy miles on it first. Then have at it.

[oldestof11]

Is it brand new or rebuilt?

[cummins12club]

Hx35 was low miles used one and the ht3b was brand new out of the box I drove it for just over 50 or so miles I still had the factory boots on the intake side of the intercooler and they have visible cracks in them I think I'm getting a bad boost leak from them first time I got on it I rolled onto the throttle and it pulled hard untill 45 psi and the just fell on its face I figured it has to be a boost leak the second time I tried it It blew the boot off between the top charger and intercooler pipe I ordered new boots for the intake side and I'm gunna have a tig weld put on the rim of the pre cooler pipe the other issue I'm having is I don't think I'm draining the chargers fast enough and oil is backing up in them I'm using stock size 7/8 drain hose w a T into stock drain port I'm gunna try and use 1/14 inside diameter line bc847 I believe u have a PDR kit and what do they do for drains?

[BILTIT]

You will want seperate drains.

[cummins12club]

Everyone has been saying separate drains I called PDR today and asked them how they drain their kits and they acted like some 12v has another oil drain provision about 12-18 inches back from the stock drain I need to look and see if mine has that they say some will not and u have to drill a hole in ur oil pan I know bc847 runs a PDR set up and I'm wondering if he had the 2nd provision or if he had to drill a hole in his oil pan and if so I wonder how he did it on the truck

[4thesporty]

Blocks with the extra drain provision are storm blocks and are 97.5+.

Best bet is to add another drain to the pan.

[RCCUMMINS89]

what is the easiest way to do it without taking anything apart? LIke taking the pan off?

[Sutter1stgen]

I added another drain to my pan. I did and now can't use that as an excuse. I put it as high as I could with the oil drained from the pan. I cleaned the pan of all paint and debris. I spot welded all the way around with a pulse mig on a low setting. I tried not to get the welds too hot, but made sure I got good penetration. No problems and no cracks. I pulled two of my valve covers off as well as my fill cap. I did this to relieve pressure if the heat on the inside somehow got worse than normal operation temp/ pressure. Im not claiming this to be the right way to do what I did. But it works and has lasted. There may be a safer alternative.
