It's tough work...but somebody's gotta' do it. Here's hoping the oil thing stays sane. Ride on.

Not sure how your engine is set up, but we had a major oil leak that we thought was coming out of the blowby tube, but it turned out our oil pressure pipe to the turbo had been chafing against some lines and had a pinhole in it. To find it we cleaned all the wet oil off the engine (it was all over the exhaust and oil pan next to the tube) and then ran it in place for a good long while to find out where a drip would spring up.

I don't remember what kinda bus you have but if it's wet sleeve and you need a rebuild it's honestly not too hard to do yourself if you have tools.

well I figured dragging this thing across CO Rockies might finish her off, and it is starting to look like that might be the case. Once I get her started she runs like a top, and pulls like a schoolbus. Even crawled across Vail Pass this afternoon - runs like normal?
This only happens when she is cold, otherwise she bumps right off?

Anything I can do to get her down the road a few more months? (2500 miles)
How long till she does not start?
Would ether help?

Headed towards Grand Junction to ask a diesel guy

Skip to 4 minutes to avoid MOST of the pain

im not sure how the cummins does it, as i dont think there are glow plugs. but hard starting at altitude can be a sign of failed glow plugs. fuel isn't preheated enough to combust.......

hope that helps

They have a grid heater in the intake tract.

well it is good to know that it might be fixable. I have been high up (8,000+ feet) and it has been pretty chilly up here.

So would ether help start it?
Is there a way to check the heater?

Dred, Cummins says NO ether!

There's a intake heater icon on the dash. When you start the engine do you wait until all the pre-start ritual* is complete? That gives the heater time to do it's thing, that is: key to run...wait*, then to start.

yes I wait, I even wait on subsequent attempts, and even cycle without starting

Yeah, seems to me the preheater grid isn't doing its thing. Typically it's supposed to (1) turn switch to run (wait to start), (2) wait the few seconds for the heater to warm up, (3) turn starter. Ford 7.3's and others do much the same thing. My suggestion would be to see if the grid heater is getting voltage when it's cool. That'll help narrow it down.

Wonder why it had issues at noon tho? - Think it was close to 70 degrees?
