I'm getting ready to perform an oil change on the 289 in my 62 Champ, and I suspect it may have some sludge buildup. Has anyone tried any of the oil flush products out there on a Studebaker V8? If so, what did you use and what were your results? I have read online that these products can clean up your engine internally and cause sticking rings to seal better, etc. I have also heard people warn about stripping away deposits that actually prevent oil leaks on old (and marginal) gaskets. The worst horror stories hypothesize that the use of an engine oil flush product loosened deposits that then clogged an oil passage and led to engine failure. The problem with doing a general internet search on a subject like this is you can find support for any position and sometimes little consent.
I appreciate your responses.
