I have a Browning A-Bolt rifle that needed work. Being used to Remington, Ruger and other Paul Mauser designs, I wasn't expecting the goofy trigger assembly that I found in the Browning. Weird setup, to be sure. You have to send the assembly to Browning to get it right unless you know what you're doing. I just bought a replacement. I equate these VGTs to that. Making it more complicated doesn't necessarily make it better.
How long should a turbo last?

I've seen Cummins & Detroit go Vesuvius through the stack. What a nightmare.
That's why I could see changing one after so many miles, but you might make it worse lol. -
Dave_in_AZ Thanks this.

The DD Detroit ran simple turbos, and now run asymmetrical turbos in Evolution, and I heard from a mechanic I trust, on all the new ones, they got away from the variable geometry ones.
Idling up, to keep oil pressure higher, helps.
I've never had a turbo go, had the plumbing come apart on a 500 series 60 14 liter, but that didn't hurt anything, just got a new clamp to replace the one that broke.
Early ISX, we had one that was replaced because the turbo failed and burned it up. Those didn't have a vg turbo.Joetro Thanks this. -
25(2)+2 Thanks this.

Manual is actually manual overide, and it wouldn't lug for any reason, and to run at a grade, you had to prevent the upshift, that, it would do.
It also wouldn't downshift at higher than 1250 rpm or therabouts, and missed them on upgrades, no matter what, manual setting or auto. The companion truck put a shaft through the trans case. I was really surprised my ride stayed together.Last edited: Dec 7, 2017
Joetro Thanks this. -
So, what you're telling me is that if I'm just bumping the idle up to keep oil to the places oil needs to be (turbo, etc...), the ECM will keep the clutch from trying to engage, so I don't have to worry about that part? -
Cummins recommended 800 rpm idle for ISX, and I believe everyone else but Volvo was recommending 900. Volvo is using the exhaust brake to load the engine to bring temps up at low idle, not sure about oil pressure.
Check your manuals, or asking someone you trust is what I'd do to be certain of what's the right way to idle an engine with a given transmission. -

Okay, so opened up the air to air again and there is for sure oil in it now. Not a whole lot but enough to accumulate. Question, how long can I go before I must get the turbo replaced?
