Hello Tom, Will these gaskets and lenses fit our original Marathon 2000 side lights? Looks like the lens is a bit smaller, please advise. Thanks

That actually is one designed by Hector. My last resort equivalent is a pressure gauge manifold. I can bring that. The key is not the device as much as having a means by which you can start at the beginning of an air circuit, pressurize it and see if it leaks. If it does go to the next fitting or device, pressurize it and see if it leaks. Keep going until you get to a point at which it does not leak. The last point you tested is then the source of the leak. Or you can start at the end of the air line and work towards the supply.
Hector may have an article about the “Texas Bubbler” in our articles section.

Jack, thanks, just got the coach 2 months ago, where is all this stuff? Sorry, steep learning curve…can you send a pic / or location in t he coach? Thx

Hey Peter and Buddy, this is great getting all the input and I love hearing the stories .
I left out a small detail in my original post,the sliding window in our slide out must broken years ago and replaced with lexan or plexiglass and it was cut to small it had a 1/4″ gap when closed.We work until November and this far north it can be as cold as 0 to 10 degrees F so I new I had to deal with it sooner or later. Barb and I work 14 to 16 hrs a day without days off ( 7 days a week) except maybe heavy rain days so sooner was a better time to fix it, so you can guess witch window was picked. For $500 Canadian ($50 US)and a half hour of my time I had it fixed and have enough lexan for another window with no wind leaks.
Now getting back to the air lock, since this happened we only use it for OTR to cut down wind noise but our grandchildren all four of them aging 1 through 6 come and stay with us now and again and they love buttons and switches! And I can guess maybe Barb or i could somehow actavate it an not know.I have sworn to check to be sure it is in the open position before I start the bus but I know I could forget. I will make a prestart list one of these days! -
John,
I started with the Ugly Fix and found the ECM was programmed to have the EGR function regardless of altitude negating the Ugly Fix initially.
That was changed in the ECM. Then I had the ECM program changed to turn on the EGR at 3200 and off at 3400 RPM. Since those RPMs are not attainable the EGR no longer functions. I then plugged the path between the EGR valve and the intake manifold to stop the small amount of leakage between the exhaust and intake manifold.
The total impact of those changes brought my mileage from 5.9 to 6.2. But………..as you all know I have been tracking fuel consumption for tens of thousands of miles on my coach so after making the last change my ECM was reprogrammed to make a slight adjustment in my fuel flow which appeared to give me more power and possibly a slight improvement in mileage.
Then at about 3000 to 4000 miles prior to the end of the current phase of the testing I saw an unexplained jump in mileage. Prior to the start of the current phase in which I am evaluating the fuel additive my mileage increased to 6.4 to 6.5 MPG. It appears to have stabilized at that level. I know from logging my fuel consumption on all my coaches that there are going to be tank to tank variations, but this latest change is not based on a single refueling but might be related to the engine “cleaning” itself of the EGR related soot. That is conjecture right now but I have had feedback indicating on teardown some EGR engines have issues with soot and particulate with the #6 cylinder most affected. I have no proof.
My coach had less than 100,000 miles when I blocked the EGR. It now has about 115,000 so it took 10,000 miles or thereabouts before I saw this unexplained jump in mileage. I am comfortable is saying that if you get the EGR shut off via programming, plug the exhaust path and do nothing else you are going to see an immediate small gain in mileage and possibly a greater gain as you continue to run without the exhaust gases being pushed through the engine.
The EGR process is intended to reduce the oxides of nitrogen. It does it by lowering the internal cylinder temp of combustion. Exhaust gas introduced into the engine isn’t going to burn so to compensate for that the ECM is programmed to add more fuel and at the same time increase turbo boost from the normal 30 PSI to 50 PSI. In effect the engine is running a fuel air mixture intended to offset the negative impact of the introduction of exhaust into the cylinder. I suspect the combination of exhaust gas plus a rich mixture may prevent the engine from burning as clean and efficiently as the pre-EGR engines.
An unmeasurable, but evident impact has been on my engine oil. It remains a clean golden color far longer than it did when the EGR was functioning. One of our members did the change to my ECM. I did the blocking of the exhaust gas. I recommend the change, not because I am in effect seeing the equivalent of a 5 to 10% savings on fuel but because I think in the long run my engine is going to be much healthier.

BCO,
We have’nt heard from you. I read on your site you had a shop accident.
Did that gray bus bite you again ?

And ladies and gentlemen that is the key. As long as the OWNER of the coach requests the records they are available.
To get service histories on my coaches I had to verify ownership by sending a copy of the title in my name.

Amazing that the couple made it out alive! I gathered the family around, showed them the pictures and explained again why we drive a Prevost!
Posting again to see if anyone has had any experience with this product. Check out the video and give your thoughts.

Here’s a ROUGH drawing..

Wow. Very interesting feedback here. I am going to take my time on this process. Wish I had a place to test these out. No matter what, it is time for an upgrade.
I will keep researching but real feedback from everyone on PC is much better than reviews I could read online. Thanks,

Harsh, way harsh.

I bought my old coach in November 2014, I bought it from a dealer. They told me what they did to it while it was in their possession. I then tried to get other service information from Liberty and from Prevost. I felt like a leper trying to get a kiss……..
I then I asked the dealer that I purchased from to get this information for me. The tried but I didn’t get anything as far as service records. I think it would have been easier to find Jimmy Hoffa than come up with the records.
This is where Jeff Rowe came in. After reading on the forum and listening to all the good things I had heard about Jeff Rowe at East Tennessee Luxury Coach I just could not wait to drive to Knoxville and give this guy some money! I called and made an appointment. I intended to find out what I had and what kind of shape it was in before I went any further. Jeff looked over my coach told me what I needed to replace now, and what I would need to replace in the future. It meant alot to me to find out where I stood. I have don’e almost every thing he recommended and still have more to do in the future.
So if you can’t find your records I would recommend you go see Jeff and get the real story from a trustworthy shop.

I’ve been looking at Legacy seats. I figure no one has more seat time than a truck driver. My seat that I currently have is beautiful. Big and wide, and not comfortable at all to me! I first saw a Legacy seat in a truck supply story I was in. Only sat in it for a few minutes, but it felt great. Prices around $800. Worth looking at. I know I will never have a $3000 seat in my bus.
