Pieces of steel in cylinder??
Thanks guys, I'll start looking into the 5.9. Pardon my ignorance, what do you mean by ZDDP issues?
ZDDP is an additive that Dyno oil used to have in it ( see edits below) that was a sacrificial ingredient between the lifters and the cam nose. It's job was to prevent metal to metal contact between these highly stressed working surfaces.
When the oil companies started not putting (Edit see below) it in any more, a lotta guys, me included,with FTH (Flat Tappet Cams) suffered catastrophic camshaft failures.
Magnum engines have roller lifters with little tiny wheels on them that roll along the cam lobes and so drastically reduce the pressure on them and the wheels.
This is a bonus to you, cuz you don't have to add the ZDDP at every oilchange anymore, which you should have been doing to your 318LA engine......... Well, those grocery-getter engines with hiway gears, will probably survive with low-ZDDP oils due to their relatively low over-the-nose spring-pressure and lower operating rpms.
I mean 4500rpm with 2.76s is ~50 mpg in first gear, and who does that....... all the time?, lol.
Corrections;
used to have lots of; and
Started putting not as much in
