Am I right in thinking that this doesn't actually cause any harm (other than to your ears)?
No, it can be catastrophic if not attended to. Someone more knowledgable will explain shortly I’m sure.
not sure that is the full explanation DG was expectingBugger!

Wanderer, we got into a discussion on ML about drysump cars and variators. There is an oil accumulator that feeds the top end, and keeps constant pressure on the variators. I have observed that with the key turned to position 3, ign. on but not start, that my oil pressure will rise without the engine running. I postulated that the solenoid valve was open and allowing oil from the accumulator to backfeed the system. I was told I was wrong. However, I have further observed that the higher the oil pressure is on shutdown, the higher the pressure observed on the next start. The theory was that a failing accumulator would have the same symptoms as failing variators. I tend to agree with this. Hope this helps..Ed
Can I just ask again for my own sanity, is the DS wet sump variator noise a different symptom from the 4.7 wet sump after engine number whatever issue?If left the lack of oil supply to the variators themselves will wear and have to be changed which is a front cover off job and far more expensive than the cap mod fix.
If left further then the worn variators will reach a terminal fail state where they will with seize or grenade. Both of which will result in catastrophic engine failure.
Yes, red covers, and as promised, here's a quick vid just now - no start today actually and no variator noise at all, engine cold, temp gauge on bottom. Previous start up was yesterday 9:00am.DS QP is the dry sump 4200 engine.
You have red cam covers yes?
Red top 4.7 is wet sump and you need to keep an eye on it.Very confused here! My 4.7s has red cam covers? I get the rattle in colder weather.
Is the red covers the dry or wet sump?
