Revisiting oil filter clamps

[GeorgiaGuzzi]

So I have previously posted about the hose clamp that was on my Quota. The majority felt that it was cheap insurance and I didn’t read any experiences of a clamp coming loose and getting chewed up by the crank. So I replaced it when I was reassembling my Quota. All is good, this post is not about the Quota.

Last month, the 2019 Mack that I drive at work developed a massive oil leak suddenly. Thankfully I was close to a Ryder location and limped it in. Turns out the oil filter had worked its way loose!





Today my shift partner call to tell me that the truck was leaking from the oil filter. I show up and this is what I find




The oil filter has come loose again! A service call later the oil filter is retightened, 6 gallons of oil (out of 11) have topped off the crankcase, and now I’m planning on taking the truck by to have all the filters replaced and the issue looked at.


Moral of story, oil filter clamps, as was stated, are cheap insurance!!! Now to see if I fit one to a Mack!

Does this mean people are still screwing their Moto Guzzi oil filters on the few threads due to the to short from the factory threaded spigot ?.   (Unless the designated oil filter from the 1970's has a thread closer to the mount face)

You call that a massive leak? Guess you have never driven a 1960 B Model Mack.

I have been driving Mack’s for over fourty years and never had that problem..but with the influx of inferior parts I can see where this is going..

I never counted the turns on my 02 Cali stone when I did mine, but I dont remember it being so few to cause alarm. I did not use a clamp.. but next change I will. Ive changed a LOT of oil in my life... over 10 years of running a quick oil change place, plus my own fleet.  Ive seen a lot of filters fail, and some loosen.. some I could write off as workmanship..[when your paying what they did then, you dont always get the best..] but some I know left fine..  Not being able to SEE the leak is what scares me a little..  So she will get a clamp next time. doesn't hurt anything.

Nope but I did work on DHC4 Caribous for 11 years, 2  14 cylinder pratt and whitney R2000 engines with roughly 42 gallons of oil an engine (dry sump).
Exxon valdez comes to mind on a few occassions.
