i had a 59 rambler given to me free , 100 k, in college , I was broke
oil filter was optional on 59 rambler ( cross country wagon) this one did not have one (!) Also experimental aluminum block , caused other issues , anti freeze / clogged radiator, pia
Guy had been putting used oil from friend’s gas station in it ,100 mikes a quart .
Drove it home decided oil change might help , removed plug nothing came out (!)
Turned out 1.5 “ solid sludge in oilpan was blocking the drain
Oil pressure ok . (!) anyway

put big screwdriver through sludge black goo came out . On my own decided flush w kerosene , not driven , just idle , Did that three times used coat hanger wire bent to L to kind of stir things up .
put in good oil , drove it at 80 , maybe 500 miles ran better and better . Changed again still black , But ended up 3 years with it maybe 50 k more miles , stopped burning oil too . (1 per thousand)
Drove sadly into junk yard running great , 150 k, body rusted out . The front seat turned into a bed . Awwright
Went on honeymoon in it !
I would not worry about clogging screen , and modern oil filter will grab any small stuff . Do it , change filter and oil 2-3 x .Maybe 500-1000 miles apart Drive it hard and fast , nothing to lose
Gunk is really a very fine particulate deposit , wont clog anything just moves to oil filter ?? remember , seeing gunk deposit in valve covers is not about what is inside engine , like bearings. Looks bad , might not be causing any problems at all Old machines get dirty ; oil pressure is the thing to watch

I would be afraid that all that loosened sludge would eventually make it to the oil pan and clog up the pickup screen.

Does anyone have experience with the Valvoline “Restore and Protect” product?

https://shop.valvolineglobal.com/products/restore-protect-full-synthetic-motor-oil-sae-5w-30

Sounds tantalizing, as do long-term effects, but I’d like to know if the claims are real. My ‘64 Imperial was owned by a spinster who lived to 105 (imagine driving with gloves/hat at 40% of posted speed limit) and there was considerable sludge on top of the heads when I pulled the valve covers during a seal and painting excursion a few years ago. I cleaned what I could but fear more exists elsewhere.

This Valvoline product sounds like it would be a good solution, perhaps there are others as well?

Appreciate feedback in advance!

Thanks,

Kurt
