Well, one of the main reasons I felt that the engine could be reconditioned by cleaning it up is that the engine was still very quiet and ran fine. My only question was going to be how much better the oil consumption would be without pulling the heads and replacing valve stem seals/guides, etc. We were on track to having a very nice result afterwards with no more cold startup smoke and no more noticeable consumption, and still the engine was quiet and powerful. Had we the chance to get the results of having Maxlife oil in the sump for a couple thousand miles, I think anyone would have had a hard time telling that this car ever had a problem. That's how good the final result was. I told him he should have no problem going another 100k miles on that engine.
Jasper Engines. All I can say is, "no thank you." Been there, done that. Just think, then he would have spent even more on the car before his son wrecked it. Plus he did not have that kind of money.
No, after not talking to me for a long, long time, all of a sudden when his car started having a major issue, he calls me and wants to be my new buddy, and I fell for it. I mean, we never get invited over to their house in the burbs 45 minutes away, and then out of the clear blue, we are over there several times in a couple of months. I bet they won't invite us over again now that I'm not needed. And that is fine. I like it better this way.
Bottom line is, he should have, and could have done way better oil service maintenance on this engine, and I offered to help with that when he bought it, telling him that the engines were known for the sludging issue, and he just said that he was taking it to Toyota for all service to keep his service record book current to help keep the value high. Ha ha. So much for that plan. I feel like an idiot for getting involved with him.
