So back in the day I had a similar situation, fixed the crank replaced the bearings all was good until! One lifter collapsed, no biggie changed out the lifter and another one collapsed, pulled the lifters apart and they were full of metallic sparkles. That meant the rest of the engine was too.
Yes that is my worry. I do have solid cam so is there a way I can flush the engine. I know I am taking a risk for me a 66 year old man, tearing all this apart is a nightmare. I dont have my lift anymore.
