I recently put a bottle of Rislone into my 77 Chevy 454. The engine is in decent shape about 60,000 miles. I've been using Mobil 1 5W30 with a 5" Wix filter. I never had any issues. Back in the seventies I used to use Rislone to get the wax out of my engines and that stuff worked! So I decided to try a quart. About three days or 100 miles after putting it in, My 454 started to pop under heavy acceleration. I pulled the right valve cover the number 6 exhaust valve wasn't opening as far as the others. Cams on its way out.
I wonder if the Rislone helped it wear down faster. After using it, I noticed my engine had a much stronger the bottom end, right off idle. That would suggest the lubes wearing down making my cam duration smaller giving it more bottom end..
Oh well now comes the fun part shopping for a USA made cam and lifters. I know there out there its just finding them. I hear Summits house brand cams are real good quality and made in the usa.. I live in Pittsburgh and I see the mills still making high quality tool steel so I know its possible to find parts made with hi quality steel. I know the Chinese make hi quality steel also but the folks who import, only want the cheap stuff or so I'm told..
Thanks..
