Is it possible to flush out oil deposits from rocker arm cavities? Pics inside.

[RobWigglezz]

Here's the passenger side rockers of my 00' 3.0L with 150K miles. Runs perfect, just wanted to see if there was any obvious excessive wear.



It seems the heavier oil deposits like to collect in the pocket of the rockers. I did clean this side up, but haven't touched the driver's side.

Is there any miracle goo that can collect and suspend these deposits long enough to make it to the oil filter.?

I just cut open my oil filter and it is doing it's job collecting these deposits. They aren't gritty and just smear into sludge. Is there anywhere else that likes to collect this stuff like the rockers do?

I cleaned mine, years ago. It was so bad, the oil wouldn't drain right at extreme up-angles. I just cleaned everything under the valve covers real.good by scraping, brushing, spraying with brake cleaner, wiping with rags and blowing it out with air. Then I did an oil change and added a little bit of Marvel Mystery oil. Then, after driving a few hundred miles, I changed the oil again.

From what I understand, this slowly dissolves gunk into liquid, not chunks to be trapped in unwanted places.

A lot said about it. https://bobistheoilguy.com/forums/threads/high-performance-lubricants-engine-cleaner.347347/

More frequent oil changes and maybe substitute 1/2 quart of oil with ATF.
