Dan,
On the new engine, did you install that sheet metal "tray" in the bottom of the valley that holds the lifters in (in case of a bent push rod) That Mondello sells?

Michael,
THIS IS A VERY GOOD QUESTION!
The little magnet that Joe sells goes in the tube in the center of the oil
filter and that's the OUTLET!!!!!
The rod bearing was damaged by a piece of something.
Dan,
On Friday, February 18th you posted a picture of a small piece of metal
sitting on your left index finger which had the comment; "This was dug out
of an oil hole in one of the bearings, just a small piece of metal." Do you
still have it? If yes is it magnetic?

Hey Dan, why did the magnet break?
Were all the pieces there with no chunks missing?

Dan,
Yes the magnet worked, the "gooy stuff" was particles smaller than the
micron rating of the filter. IIRC you said you used WIX filters, both the
51258 and 51049 are rated at 21 microns.
Bruce,
IIRC the oil flow through the filter is from the outside to the inside. The
oil enters the filter through the series of holes around the top and leaves
through the center. This is standard filter design - from the largest
surface area to the smaller surface area - right Jim?
I too bought Filtermags, one for Double Trouble one for The Blue Streak.
After I got them I realized that whatever stuff they caught was stuff
upstream of the element. I wonder how much of that "oily goo" would have
been caught by the by the filter element?
The final question is would particles that were "gooy stuff" and "oily goo"
actually do any real harm in the engine? In theory they would be, for the
most part, smaller than 21 microns.
Yes, I do realize that larger particles could get into the engine whenever
the filter bypass opened.

Rob M.

I bought 3 magnets that go inside the filter like the ones Dan used. While carrying them in my shirt pocket back to the coach at DuQuoin one broke in half. I think they are very brittle, probably due to being a very powerful magnetic compound. SWAG

OK if the magnet, and I have one, pulls out stuff from the oil, how will this distort my oil analysis from Blackstone Labs? Should I pull off some of the goo and mix it in the oil or send it separately to Blackstone? Should I tell them about the magnet?

Doug,
This is a good question.
Magnets trap ferrous iron or steel particles so in theory it would lower the
amount of those types of particle in the oil sample. That means particles
from the rings, cylinder walls, valve springs, valve stems, etc. Bearing
surface material is non magnetic.
The little magnets that Joe Mondello sells wouldn't hold much crud and the
ones that go on the outside of the filter would trap magnetic material that
might have been trapped by the filter element itself.
Regards,
Rob

Rob, the particles in question find their way into the lifters and their oil
passages, restricting the size of the galleries. Also collect in cross
drillings in the crankshaft, doing the same thing. They resemble very fine
valve grinding compound or rubbing compound that you use on paint. Very
abrasive, not something that you want any where within the engine. Over
time, they wear out cam bearings, rod bearings, &&&. Change that oil often
and do not neglect the filter. Bigger filter can is better in my opinion
than the smaller ones.

Doug,
If you include a smear of the "oily, gooey" stuff you will make the
concentration in the sample extremely high. Perhaps a smear in a separate
container.
Good Luck,

Jim,
Got it!
Oily goo = sludge?
What do you think of my plan to change the oil / filter in Double Trouble
once a year at 4-5000 miles?

Rob, I know that you are using a very high quality oil/filter combination,
and that combined with the fact that the use of the motorhome is nearly
always long term, fully warmed up and at highway speeds, that mileage
interval is probably O.K. I would not go much beyond 5000 miles in any case
and that is further than I would personally go. I change about 3500 miles.
It is something that I have always done in all my vehicles. We used to have
a flower shop and our delivery vehicles were 3 liter Ford aerostars or 4
liter full size E-150 Ford Vans. They were used in stop and go delivery
service and oil changed at 3500 miles. I drove the first one 166,000 miles
and traded it because I thought that we needed something newer. It was still
running great. I drove the second one 250,000 miles and the rest of the them
the same mileage. None were using oil, but one developed a leaking rear main
seal. When we sold the Business in Jan 2009, we sold the vans with the
business. I drive by there from time to time, and the vans are still in
daily use. I do the same thing with my personal cars and my collector cars.
Hard to argue with success. I would rather spend my time fixing other
peoples engines for money who neglect maintence than my own. No science
here, just common sense.

I change once a year or a 6,000 which ever comes first. I always change it before I park it for the winter. My last two Blackstone oil analysis came out just great on an engine the has 90,000 miles and 34 years on it. The engine has always had Rotella 15W40 in it. Both I and the PO always used Rotella. At 100,000 I intend to replace the timing chain.
I ran one oil analysis at a local truck stop a few years back at 5,800 miles and the report came out DO NOT CHANGE the oil for another 3,000. I changed it then because it was time to park it for the winter.

I remember when Veedol touted the motor oil that exceeded the 2,000 oil
change. I worked for my uncle who owned 32 Dodge, Chevy and Plymouth taxis.
They ran 1,000 miles a week, not counting the idle time to keep the hacks
warm in winter and cool in summer. I change the oil in 16 cabs each
Saturday. Back then we used Quaker State 20-40 Super Blend. They showed
200,000 miles on the ODs when being retired.
In 1973 I bought a new Audi 100LS. Audi used Kendall GT 1. Recommend oil
change interval was 10,000 miles! I had two friends that had the same cars
- both needed engines before 50K - they followed the manufactures
recommendation. I did not. Oil & filter every 3,000 miles. Ran it over
100K, and itran great except the throw out bearing went.
IMHO changing oil - which is the life blood of the car is cheap and easy.
They used to say that the oil system provided up to 40% of engine cooling.
I'm not sure if that's true, but it is another reason to keep the oil
changed and at the full mark.
