Re: Another Skoolie!

Agreed, the O2 sensor dangling is likely the root cause of your troubles. You may have better drive ability by just unplugging it altogether forcing the computer to open loop.

Re: Another Skoolie!

There you go. A bent pipe restricting exhaust flow and an oxygen sensor out of the system--easy peazy! BTW don't plan to drive your bus any distance in limp in mode. The computer is going to richen the mixture to prevent stalls as well as retard the timming to prevent pre-ignition knock. Both of these will cause the engine to run hot if you go very far and could do permanent damage to the engine. Plan on doing a computer scan anyway just to be sure there arent other issues. I'd bet that once the pipe and oxygen sensor are repaired (replace the O2 sensor--the're cheap and play an extremly important role in engine management) and the codes cleared with the reader, the bus will hum like new!

Nag nag in the back of my head--why is the O2 sensor out? Did it fall out because the bung threads are bad or did someone try to pull a fast one or did the exhaust pressure blow the O2 sensor out to relieve pressure when the pipe folded???????? I'd sure like to hear the final tale!

was never an issue. I did answer that on a post. The muffler broke off at the weld on the muffler itself. It dropped straight down with no bends or kinks. The oxygen sensor must of found another way to pop out or I can tell you by looking at it, that I am not sure if it was ever really plugged in. It was rusty and appeared unused. When I got to the bus, i tried to start it, but would not turn over. I unplugged the sensor and tried again... nothing.

I live almost 2 hours from this bus and I was not leaving until I got it to the mechanic. So I called the tow truck in and had it taken over to the shop.



It turns out that none of that mattered. I got a call today and the mechanic is almost 100% positive its a catastrophic failure in the engine. Leaking fluids of all kind (including antifreeze). It looks like maybe a busted seal or blown rod. The power loss was possibly antifreeze in the cylinders. The o2 sensor had not been working in awhile and believes that it may not have been an issue. He is spending a little more time on it to see if the rest of the bus had a problem. I am sadden by this, but I am not giving up on my bus. If I can get it for a reduced price (bus without engine) then I will be starting a complete, ground up, out of my league, rebuild project.

Thanks for all the comments and help with the first full 3 hours with my bus. Ill update this as soon as I hear more.

Re: Another Skoolie!

on another note, keep checking it out...it's a SBC even with a bad head gasket it will run and mean it's one of the tougher engines.

Did it over heat?

just weird for it to loose power and then it has a bad motor

I have put a few holes in the side of the block 6000+ rpms and even broke the crack at the #1 bearing it was very dramatic...no warning just fire and brimstone

I am curious, for sure make sure 2nd opinions are considered

what exactly did it do?

was it running hot?

what kind of oil pressure?
etc

Re: Another Skoolie!

Hmmmm --- sure makes me wonder. For a basic 350 to go from "losing a little power" to catastrophic with nothing more than a questionable sensor and a dropped section of exhaust is a mighty big leap. Course I'm going on the info here so far, but still...

Re: Another Skoolie!

Thanks!

I am going to go over the entire situation for you guys because you are interested and so I have it to remember... as if I can forget.

First - Since this may be the last time I post, I wanted to tell you a little about me. I own an adventure company in Wisconsin. We specialize in guided trips through out the state. I currently lease passenger vans for the trips. Looking to expand and grow into our own bus was my objective with this. Not to mention all of my trips are overnights and focus on education and experience more then just leisure camping trips. We are a American Red Cross Certified Wilderness First Aid instructors group. The Boys and Girls Scouts use us a lot to meet their required training and overnight canoe camping regulations. Its really my love for the outdoors and adventures, mixed with getting paid to teach others how to love it as well. My only requirement for this bus was to have a solid motor. I needed something I could trust out in the woods to get a dozen Scouts back home after I have worn them out. The rest of the bus I had all winter to work on because I have a heated warehouse and the tools to take care of it.

Here is what happened from the beginning:

Friday I picked up the bus. I drove up with a buddy who had looked at buses in the past. Test drove it around and it seemed fine. I could tell it needed things like some exhaust work. I had no idea that it was about to fall off, but I could see and smell small amounts of exhaust from the manifold and under. Small holes at best. Some rust. No biggy. Drove as I imagined a V8 would drive. Acceleration was OK and drive was smooth. I had every intention to get a tune up and replace the things that needed to be replaced. Transmission seemed to be in working order as far as shifting in and out smoothly. We bought the bus and I was happy. It was around 2100 so my buddy and I stopped for a steak and talk about what to do next... Wild fantasies of new paint jobs, interior configurations and trips to come. Everything was good. Even out waitress was excited to hear that we were in town to buy a bus. She told us about when she was a kid her parents had a bus and they rented it out to a french man that was in town. She lost me at cheetah underwear that he would walk around in...

We started driving back to Madison which is roughly 2.5 hours from Green Bay. The roads are 65 all the way back. We decided to take it easy and do the speed limit. Everything seemed fine for 20-25 min into the ride. Appleton is the next major city. While driving, the motor made a bang noise. It smelled hot. The speedometer stopped too. It slowed to 45 mph with a rough sputter. We pulled down the next ramp and parked. We reviewed the truck and nothing was hot. The radiator was warm to touch, the rear heater in the bus was feed from a line from the engine and that was working fine too. It started with no issues but was loud. Checked under the bus and sure enough the muffler was laying on the ground. It was really hard to tell if the motor was clanking or the exhaust was clanking. By this time is was after 11 and nothing was going to be done. We had parked in the parking lot of the mall and right in front of Sear Auto center. The plan was to come back on Saturday and see what we could do.

Saturday AM I called Sears to see about scheduling an appointment to get the exhaust fixed. They would not look at it due to size. Called around and no one really wanted to look at it. I was experiencing what its like to own a bus... I was thinking to "in the box". I though of Fleet Farm. Happened to be one about .5 miles away from Sears. Lucky me it had a HUGE auto center. The worst case was that I could work on it in the parking lot and have access to parts. I bail wired the muffler up off the ground. Started fine and drove very rough to Fleet Farm. Fleet Farm would not put it on their lifts. I was ready to tackle the a couple things when I was asked my the nice folks at Fleet Farm that working on the bus in the parking lot was not in the best interest of Fleet Farm. I though to myself, Ill just explain that I was just going to cut out this muffler and replace it with a new one from your store, then dig around until I find any other issue... But that just made me laugh and instead just agreed with the nice woman. It was Sunday around 1700 and I could not do much about getting it to a local mechanic. I took a bunch of photos and posted them here, as you can see from the timeline. Things started to click on ideas, but with the bus 2 hours away, it was hard to test my thoughts and your ideas. On Monday, I got a hold of a company outside town and they were willing to take a look. It was raining and cold on Monday afternoon and I knew the weather on Tuesday was clear and sunny. Tuesday around 0500 I drove up, unplugged the O2 sensor and tried to start it. Would not turn over. I went back underneath and noticed fluid on the ground. I plugged the sensor back in and tried again. Nothing. More fluid. I called for a tow and updated you yesterday.

Since then, Its been confirmed that the motor was done. I asked for an hour of labor to go over the rest of the bus and let me know if anything else looks bad. Got some comments about the rear brakes, some rusting to the motor mounts and under drivers cabin. Overall, he said it was just OK. The body and interior are great, but underneath and motor needed work.

I called the guy who sold it to me and he will take it back. I really owned it for 30 min worth of driving. He is at a loss and disbelief. He has said he had no issues with it. I believe him. He is looking back to the guy that he bought it from asking about the rebuilt motor and the less then 40K that was reported on the motor. The mechanic said it did not look like it was a rebuild. I am tiring to decide if I buy it for the bus and buy and install a new motor or I have it towed back to Green Bay and write off my loss of 500 bucks for towing, service and parts. (not to mention my 4 round trips) If I keep it, I need to then have it moved to Madison. Which would be another adventure.
