ring flush results

[turbo]

excellent results. thank you savvy aviation for making me aware of this procedure. some comps were in the low 70's with air leaking thru the oil fill tube. with some fluid leaking out the exhaust pipe during the flush I also removed the valve cover and gave the exhaust valves a good hit with my huge rubber hammer. comps now back to high 70's and oil consumption up from qt/8 hrs to qt/15 hrs. carry on.

I think this is a useful trick. What did you do with all the "effluent"?!
The cleanup is the biggest hassle

How about posting a link to the instructions?

I just did this in the last couple weeks.

I for one thought it would be a great idea if it would work. Nothing to loose and a possible cheap helper.
I have an RV-6A with an 550 hour 0-360 Channel chrome cylinders, CS prop, SDS fuel and ignition burning a quart in 5 hours Areoshell W100 on Costco Premium. Compressions all good and borescope clean.
I did the flush per Savy instructions on a cold engine.
Cylinder #1,3,4 all flushed fine, But #2 the prop wouldn't turn. Did it 5 times and prop VERY hard to turn and solution just dribbled out.
Flew for 5 hours and repeated 5 times on #2 on the hot engine. I got the solution to flush out at about 40 percent of the other ones. Prop still hard to turn, But, it turned.
So? did it do anything to reduce oil consumption NO
I found no change. Good? bad? Not mine to say.
I am going to fly for another 10 hours and flush #2 again.
I even ran mineral oil for 40 hours before just for giggles. Then change to Phillips 15 40
Probably just fly and burn oil, Runs and starts great.
Not going to complain cause I've heard of others oil consumption and tell myself, I maybe lucky.
My three cent worth, Obviously your luck may vary, Art

Probably (always assumed) this is the original. Came from eth Camguard guy. It did unstick some rings for my hangar neighbor and help his oil consumption. Hung a sandbag on the prop because it was in hydraulic lock. Next day was able to flush with hand force only.

I’ll be doing this at the next oil change on my Pacer with Lyc O-320-A motor. It has 850 smoh and uses 1 qt/4-5 hrs. Chrome cylinders, good compression, runs great. Thanks guys for posting your results. I will do the same.

turbo - - thanks for posting the results, a couple of questions if you don't mind -

a.What oil have you been using, predominantly.

b. does your engine have cooling jets under the pistons?

c. last - do you have timing advance, i.e. electronic ignition

Just curious as to some of the factors that influence the plugging of the oil return passages. I thought some pistons had larger return/relief passages, but I don't know much about these details.

Thanks,

I drained it into a 5 gallon bucket and saved it for next year.
