Engine rattle.
Hi Guys and gals.
Just after some assistance in diagnosing a rather troubling rattle. I usually have the radio on in the truck. Not loud. But a more moderate volume. So can hear the engine generally what it's playing at. I've done a fair amount of miles in it. Oil pressure is over half on the gauge. So hadn't thought it was a lack of oil. It's quite a high pitched one but like an exhaust shield or alike. Not like a bottom end knock. Or doesn't sound like one to me. Not sure whether it had had a valve job done before I got it. It's done over 100k miles. Had done just over that before I got it. Plus it was super quiet. Although I had bought the bits to do it. Never seem to get time.
Anyway. It seems it's quite light noise wise. Not like a deep rumble knock. Cant be at tick over or just above. Does seem to disappear at some points.
What would you be looking at first.
Thanks in advance.

The oil gauge is an idiot light, it reads mid scale for anything over 7psi . So keep your eye on the dipstick , My engine eats oil , most do . This engine needs 16 to 20 psi minimum .
I do a walmart engine flush every other oil change , i use a good grade syn 5w-30 and one quart of marvel m. oil , its a good cleaner . Don't waste your money on high mileage oil ,it all gets dirty and dirt is hard on this engine .
The cams are controlled hydraulically with dirty engine oil . Get rid of it before 5k or 4 months .
When we do a timing job we put a melling hv oil pump in because the factory one is not good . Many upgrades on engine internals to get better flow ,rollers,lashs etc .

Thanks for the reply. I wasn't aware the gauge showed such a low reading. Most gauges I've come across in the past are up to between 70 to 100psi.
maybe I ought to get an aftermarket one to keep an eye on it. Or even a pressure switch to a light maybe better than the gauge. Any suggestions greatly received.
As regards the oil good point re the marvel mystery oil. Worth a go.
Thanks Roland

Did an oil change and good flush. It seemed there were deposits of what looked like copper particle in there.
What would be the thought that could be?. Thrust bearing faces??. Or maybe something else?
Thoughts as to what it could be would be a help.
Many thanks
Roland
