Engine is TOASTED

luvrbus · September 02, 2015, 02:55:19 PM

Some one is pulling your chain telling you the engine won't start because of low compression in 1 cylinder

Give Don a call at this URL. That's where I got mine.

Tell him Joe Laird told you to call. He's a great guy!

It ran coming in, it aught to run coming out. They have you over a barrel and they know it.

Quote from: Scott Bennett on September 02, 2015, 12:39:53 PMSean, my stomach is churning. we just talked yesterday and my wife had a great probably 40 minute chat with Angie too....any chance you can get it started and drive it somewhere or is that too risky for you? Guys, just to put it in perspective, most of us might take the risk of driving it and getting stuck on the side of the interstate with the hopes we might make it to a better shop, but Sean has his wife and 4 kids and a kitty to think about so being stranded on the side of the road may not be his cup of tea with a big family to keep safe

Call Gary at B&B you might be surprised how much he will charge to install a L10 or M11 in your Eagle it's not that big of a deal as you could order a Eagle with Cummins engine

Sean,

I want you to know that I am praying for you and your family.

Your bus was running when you brought it in. You had the oil changed and new fuel filters put on and now it won't start. All of a sudden you need an engine rebuild. How was it running when you brought it in? Did they do anything else beside oil change and filters? It doesn't make sense to me. How can an oil change morph into a needing new engine?

Sean,

I am with Gary on this one. It was running well enough for you to get in the shop--not missing, etc. and on the highway keeping up to the speed limit, so it should run.

Time before last when I had some air bags replaced, the shop had trouble starting mine and replaced the pressure switch on top of the primary filter, and it seemed to be OK. One camping trip later and in the shop to install the Jakes, the shop(different -better one) they discovered a hole in the fuel supply line just ahead of the rear bulkhead. I was having problems keeping it running at stop lights and very poor acceleration. With the line fixed, it races like a ~~Porsche~~ ~~diesel VW~~ Honda trail 70

Ask them to humor you and start with the basics, tracing fuel lines, etc. One dumb question--are you sure there is enough fuel in the tank? When I way home from purchasing my bus, nearly a whole tank of fuel was stolen--WHILE MY SON AND I SLEPT IN THE BUS AT A TRUCKSTOP!!! The next day I discovered it by happenstance, because with no gauge I wanted to make sure it was FULL-FULL before starting to drive for the day(Divine intervention)

Hey Gary -

My same thoughts initially. My wife can't figure it out either. I think we were blessed to make it here.

Here's the run down one more time-

We came out of glacier national park and the engine was smoking a bit more than usual and running rough. Didn't seem right. I thought from the symptoms maybe the Turbo was causing the issues.

Checked everything out on the outside...didn't see anything unusual or out of place. Drove the bus two hours south and had heating and loss of power issues and bus was running quite a bit warmer (actually the engine bay door was hot to the touch) the Turbo and pipes were sizzling.

So I decided to take it in to get the oil change and fuel filters changed and have it checked out. First tech forgot to close the valve for the priming pump which he used to prime the fuel filters.

An hour later the 2 stroke guy asks me to start it up for him. It starts right up and slowly dies and before we figure out the valve is open it stalls out. So we prime it with the pump and try again...no go. Try again...no go...more fuel...no go...then after about 20 minutes of priming, taking off the filters and checking that the fuel pump is working, it won't start. 2 stroke guy goes home.

Come back in the am he tries with some quick start spray in the Turbo. Nothing...so he goes through and checks the blower, checks the fuel pressure...etc. After an hour he scopes the cylinders. Cylinder one is super soaked with oil. Cylinder 2 is dry as a bone and cylinder 3 is heavily scarred.

At that point they determine it needs a rebuild. And now here I am. I wouldn't have believed it if I hadn't seen it on the scope. I really had no idea what I was looking for but you could tell it wasn't right.

And now here we are. Not sure they could sabotage the cylinders and if I didn't know better I'd think running the engine out of fuel could damage ththe cylinders.

So I guess in hindsight its a blessing we made it there. Wish we could have moved it somewhere else but not sure how far we would have got.

Wishing you good luck Sean, my prayers are with you, tom...

eagle19952 · September 02, 2015, 06:50:06 PM

i think i would call that fellow that Joe Laird has in mind... your ONLY about 500 miles from Edmonton AB.

the DDEC ebay 6v92 motor in Indiana is 320hp.... removed from a wreck...

luvrbus · September 02, 2015, 06:51:59 PM

Your oil pressure hasn't been getting lower has it ?,those engines will run on 2 cylinders all 6 could not be low on compression,he should pull the valve and make sure it's not a gear train failure

chessie4905 · September 02, 2015, 07:12:38 PM

Before all this started to happen, did you let it get hot, even a little, on some climbs? Trying to figure out why all this started.

B_K · September 02, 2015, 07:22:52 PM

I'd give these guys a call! Me and several others I know in the charter biz bought remanufactured engines from them AND WERE WELL PLEASED.
Dad an I bought a 6V92 mechanical from them for one of our MCI's and it ran like a top after we brought it home an installed it.
We also bought a bus from them once after a guy had them do an engine in it and then could pay up so he handed over the title! BEST running 6V92 I EVER SAW personally! Our drivers swore up an down it had to be an 8V92!

OK, So the engine is hurt. We all agree on that. This is how you got here now.

As an independent diesel repair shop, I'm having a hard time believing this. Oil and filter and a botched fuel filter replacement isn't gonna need in inframe. if they can't start it now, How are they gonna start it after overhaul?

I have plenty of thoughts on this, I don't know your specific arrangement. Has anyone put a gauge on the secondary filter and read the fuel pressure? That would tell us if the blower/fuel pump is turning.

Do you have any type of emergency shutdown system/device. Do you have Jakes, Are they on?
Has anyone pulled a V/C and verified the injectors are in the fuel/run position?

Time for basics here, Sure, there's a lot of moving parts on a 92, But it'll run with a couple of weak holes.
