My brother's LBZ and my Dad's LMM have the "typewriter tick." What is the best solution to get rid of it? They both run Rotella 15w40 and I noticed it on my Dad's the minute I changed the oil.. is the Oil what really causes the tick or what is it?

Interesting. I run 15w/40 on my built motor and my other Duramax's with Napa filters, never noticed the typewriter sound but maybe there is one.
I am currently running a syn 15w40 with a Wix filter. Mine has the typewriter tick, has since new. I've used synthetic and conventional oil (always 15w40), and AC Delco, Amsoil, and Wix filters.
I was told it was little
Small air pockets in the oil , that gets between the bearing and crank surface and the it makes that noise . But again I was just listening when I was told that

It doesn't seem to be anything to worry about. At one time my truck did it, but for the time being it has stopped.
Any luck getting it quiet with 2 stroke oil or a fuel additive in your fuel? I put the 2 stroke oil in mine seems to smooth it up and lift pump seems to like extra lube either type seems to help it get smoother a bit. Maybe it's conjecture but I guess that's what it sounds like running a tow tune EFI. Just enough extra power if that matters.
anyone else noticed the motor smoothing out using 2 stroke oil .. Just curious .. more lube is always a plus :thumb:
new oil makes it tick more, once the oil breaks in then it fades a little. mine was always very noticeable with rotella t 15-40 which was all i ran in my motors
