Oil Leak Redux . . .

Spend most of the day at work designing new labels and printing up a lot of other labels using Avery’s free Design&Print program. We have a number of products we buy in bulk and then bottle ourselves, or buy bottled, but unlabeled.

Here’s a sample


When I got home this evening I realized I had left my phone at work. My client had stopped me on the way out the door and asked me to take a look at something, and apparently I laid it down.

So, though we had planned to eat at home, this seemed like a good excuse to go back up to Clear Lake to retrieve it, and of course, stop off at Yummy Yummy Chinese Buffet along the way for dinner.

I need to get back on my continuing rig oil filter leak saga, so tomorrow I’m going to put in a call to Cummins to get some more info.

Back this past March, I pulled the old oil filter off the engine and did my best to clean the area where the rubber gasket seats. I was able to clean the mount except for what looked like some discoloration on the bottom of the seat. I’m calling it ‘discoloration’ but I could feel it .

However I was afraid to do any real scrapping on it since I wasn’t sure what the flange was made of, aluminum or steel.

So I put the new filter on after soaking the gasket in oil as recommended. And a 15 minute high-idle test showed no leaks.

Then the next day Jan and I took the rig out for a test drive. We did a little over 50 miles, at both Interstate speeds and side roads. Getting back home and taking a look, I found no oil spray on the rear of the rig, and none around the filter underneath the rig.

So we were good to go, right?

The next Friday morning we headed up to Kingsland for our family get-together at Chris’. Along the way we made a stop at the Buc-ee’s up in Katy, about 70 miles away.

And found oil on the truck and on the rear of the coach.


So either the filter suddenly started leaking between 50 miles and 70 miles, OR the extra load from towing the truck, (the only real difference from our test drive) caused the filter to leak.

Which is the one I’m going to talk about with the Cummins’ Tech.

And while I’ve got him on the line I also want to talk about flushing the green coolant out of the engine and replacing it with red. It’s getting harder and harder to find the green now, so I want to know the flush procedure.

You’re not supposed to mix them, but I’m not sure how much ‘flushing’ I actually have to do. Can I just drain the green and replace it with red, or do I need to flush it out with water first, or what?

I guess I’ll see tomorrow.
