Hello,

I've got a 1990 MCI 102c3 with a 6v92TA engine that my band uses as its tour bus.  The past few days I've been noticing some smoke, white-ish when I start it, then looking darker after I've driven a while (and generally only showing up when I floor it). Two nights ago it got noticeably smokier, but was still running strong. Then last night I started losing power on the highway and suddenly kicking out massive amounts of smoke, even started filling the cab, so I got off the next exit and saw it was mostly spilling out around the engine compartment, not the tailpipe. I opened the engine compartment doors and it looked like the smoke was mostly coming out from above the engine, blowing down from the fans (or maybe the fans sucked it up there and shot it down, I don't know, it was so smokey and hard to see). I parked at a gas station and am now writing from a Motel 6 on a Sunday morning.

I'm curious if anyone has a guess as to what might've happened, but mostly I'm posting here to see if anyone knows a good mechanic in the Indianapolis area? I fear we're going to need some major engine work, so want to go somewhere reputable. I'm willing to have it towed to another town, but of course I want to keep costs down, so hopefully won't have to go too far...

Thank you!

I've been using Interstate Power (istate.com) in Milwaukee for our coach. They have a location in your area. They're not the cheapest, but they seem to have a good staff and parts network. The most important thing is to be sure and fully communicate with the tech (not just the service writer) so that everyone is on the same page and knows what you want them to do.

Man are you LUCKY! You could not have broken down in a better location. KING BUS MONKEY Scott lives in Avon, a west side suburb of INDY! Which Motel 6 are you at?

My guess is that you have a clamp busted or loose on the turbo. (or some other major exhaust leak)

Scott should be able to get it figured out and fixed up pretty easy.
You should send him a contact name & #.

Doesn't sound major maybe a broken exhaust pipe or bad turbo but you should have heard a broken pipe

Thanks for the replies everyone---Quick update: went out this morning to start the bus in the daylight and saw that yes, one of the exhaust pipes had busted clear off near one of the clamps and was spewing out the smoke, while also spraying a bit of diesel. Does that sound like a bad injector?

I wrote Scott, and tracked down a place called "Stoops Freightliner" who says they work on buses. Not the best reviews online & the labor rate is high, but it's the only place open on a Sunday, so I might have it towed there...

thanks again, Aaron

You might just have a broken exhaust pipe. Can you take a video and post it here of your engine compartment while it's running?

Iím too busy at the photo studio this week to get to that, but it sounds like an easy enough fix it doesnít take a 2stroke guy to fix an exhaust.

Hope you didn't waste $ having it towed to Stoops!
If you absolutely had to take it too Stoops, you can drive it easier than towing it.
If it were me I'd take off the broken pipe and take it to an exhaust shop the can either build you a new one or weld up the old one.
If you could post a picture of the broke one I might just happen to have a used take off on the shelf in my shop.
