I'm listening to the February 25, 2017, Hour 1 episode of the "Ron Ananian: The Car Doctor" show ( http://www.tomrayconsulting.com/car_doc_audio/downloadpodcasts.php?file=car_doctor_2pm_02252017.mp3 ).
Ron has a caller that says he thinks he has some varnish deposits that are causing his rings to stick, and wants Rons' advice. Ron tells him to add a quart of brake fluid and run the engine at idle while you carefully monitor it. Ron says he will sometimes do this at his shop and run a car for up to three (3) hours! After that, he'll (of course) change the oil. Ron says this technique is a last resort to un-stick some stubborn varnish deposits off your piston rings.
(If you want to hear the call, it's around 16:30 into the podcast).
My questions are...
1.) Has anyone tried this? I've got think brake fluid circulating throughout your engine would be (at the very least) a huge risk to ruining your seals, wouldn't it?
2.) If you've got really stubborn piston ring deposits, won't some of the oils we discuss all the time (like the Pennzoil yellow bottle?) be a MUCH better way to safely remove ring varnish? Wouldn't the caller be much better to just change to a high detergent oil and wait for the rings to become clean on their own?
