We all have had some bad luck with substandard parts and/or hired labor. Some of us more than others. That’s why we (I) try to do as much as we (I) can ourselves, including R&D at great cost in time, money and frustration.
Some of us like to give the supplier of substandard products and workmanship a chance to correct the issue. Some of us even prefer to learn for ourselves. Most of us like to hear other people’s opinion too, whether or not we act on those opinions. That’s why we (I) like to read those thoughts and ideas on these forums and write in on occasions about our experiences, good or bad.
As far as substandard products and workmanship, my P400 header exhaust leak comes to mind, as it has been brought up in a recent thread. In conversations with the supplier not the manufacturer, it was decided to send them back to be repaired or replaced at no cost to me, except shipping one way and the labor to remove and replace them.
Here is the email I received from Mitch because Matt has been out with a serious medical condition (possibly one of the reasons for not being in business anymore?):
“Jody, we believe we have found the problem. Over the years the cylinder heads have been produce by different foundries and each time there are slight changes in casting and machining. Why I wanted the picture was to see which heads you have. Basically what is going on is the area that is machined for the exhaust manifold to seal too is smaller and the flange of the exhaust manifold is not quite sealing because of interference with parts of the casting mold seam (where the two halves of the mold come together). So when you used silicon or a gasket it would seal at first and then blow out as the bolts worked loose from the heating and cooling cycles. The fab shop is going to make sure that you have the clearance that you need.”
Now that they have been reinstalled but being late in the RV season here in the frigid north (-33F yesterday morning) I really didn’t get a chance to test them out. Although, I did drive it some around town some. I had the oil changed, fuel topped off and the LP tank filled before parking it for the winter. I did leave the doghouse cover off during these short drives to watch and listen for exhaust leaks. It was hard to see if the headers were leaking at the heads because of all the exhaust coming from the collector connections. (see pic)
Hopefully it will warm up some so I can get in there and see what needs to be done to remedy the issue. My original thought was to simply tighten the clamps, but I’m not sure if I would be able to tighten them enough to stop the leaks without breaking them. So, plan “B” came to mind. What if I ordered out some Remflex collector gaskets the right inside diameter, then trim the outside to fit inside of the clamp? Then, hopefully I’ll be able to see any leaks. The true test will be to drive for a couple hundred miles hard like I normally do. But that will have to wait for warmer weather. This whole project has been a giant frustration, with substandard parts and workmanship (which I’ve written about on here in various threads), but I just keep going forward and hopefully someday it will all come together.
Of course this is only one of my 6.5 projects. My K3500 dually isn’t so much a “project” but it is something to maintain and I could write another book on the substandard parts and workmanship that I’ve had with it. And, of course there is the substandard products and workmanship that goes with my house too.
All my life I’ve tried to do most things myself, learning the hard way. As I get older and more physically challenged, I’ve been trying to hire more things done with limited success. I used to have buddy/friend/right hand man that would come over to help whenever I needed, but he passed away last Nov after a brief illness. Now I have to rely on hiring more done, which I’m learning is hard to find, first somebody willing to do the work and second to do a good job. It seems this is a common thing these days.
So keep sharing your ideas, thoughts and experiences on here so we can all learn more, even if it ends up being the hard way.
