I might get shyt over this BUT: Laughing

In the past I would drain what I could and then pour a quart of Berrymans Carb cleaner and top off with new oil with new filter.
Run it around 1500-2000 rpm for 1/2 hour to get warm. Drain oil and remove filter. Fill with new oil and new filter. Run again for 1/2 hour. Drain oil and remove filter. Then the crap should be out.
Don't forget to add oil and filter when done. Mr. Green

If its really sludged up I might swap filters halfway through that half hour... keep an eye on oil pressure.

I have flushed using Berrymans and Seafoam both using the above described method. Works well, just one time had a scare because the filter filled up fast Shocked

Saw the oil pressure staying lower at the same RPM so shut her down and swapped filters, added some more oil since I lost some with the filter swap, and got back to it. Then new oil and filter as stated.

I cant say if Seafoam or Berrymans is better- there are many on here with better knowledge of chemistry than I- but both worked...

I don't like motor flushing....loosens up all sorts of stuff and can/could plug pick-up screen.

i agree

if you have junk that loosens up you have problems
aka high mileage motor with lack of maintenance

if you gone through problems like i have you replace bearings etc or flush with motor oil

anything else is B.U.L.L.S.H.I.T.!!!!!!!!!!!PERIOD
take the time and do it right or your just fucking around playing pocket pool

nothing goes through bearings other that oil
seafoam is for your fuel system

ask your bearings what do they want......OIL ONLY

first of all, what exactly do you mean by "gelled" ? is it actually sludge from crappy oil and lousy maintenance or is there some weird oil in the engine that turned to jello ? honestly im with squeeezer. i dont like ANY engine flush. that being said, what are your plans for the engine ? if its in a car thats about to be sold or traded in then by all means flush away. if you want to keep it then theres no way but the hard way......... pull it out and tear it down.

Old school stuff Marvel Mystery oil never failed me. 1 quart in a fresh oil change and run it. Change after 500 miles or less depending on how bad it is. Keep an eye on the stick to see how dirty it is getting change sooner if needed.

Surprised none of the other old guys thought of this stuff.

i just had a 65 4 door chevy in the shop friday

it had a jug of the marvel mystery oil (the jug was originally a different brand) piped directly to the intake for" top end oiling"
i guess the point was to introduce it to the combustion chamber for the top ring

i didnt agree with that ........but just a piece of old school i guess

Jon, in 1982 I had the guru of used car salesmen come to me and said put the top oil in the carb!!!!!!!!!!! The GM top at the time!

I opened the can and fugging pegged the motor and poured the shyit down it and nevere heard a fart. Pretty much oiled the crap out of everyone but the used 72 PU lived.
It got sold and I got layed because I told the drunk Service Manager I could not Fuch people on the used cars!

Oh I forgot,, Remember the cams that were were going flat then???? 1982?

Doing a few cam changeouts the fuggen Drunk service manager had the balls to ask if I could tell the customer the timing chain caused the cam to go bad!
So when the customer looked at me?
I simply said GM has had a problem with the cams!
Oh yea the timing chain is good!!!

I got layed again.
