Rick - Not to debate the wear issue or to differ with your opinion I ask you the following question. Why is the service life of a normal production desiel engine around 400K miles, but in most production gas engines it's about 150K miles? And that's with normal
oil changes for both. I know the right answer but it's a bit more complex than this threads contents need cover. I will say it has nothing to do with
oil control systems or residual
oil films on metal surfaces on startups. And that's basically why I largely disagree with a lot of your post above, and believe your trucks engine will wear out per normal mileage anyhow, regardless of what you think you've done. As for the dry vs wet and F.I. vs carb. we can debate that one forever. Maybe later. As I said above, I am switching over to a road racing dry sump late summer and the only REAL advantage I personally see with them is that they are for cars that get thrashed around hard. That's it! As for the drag dry sumps- they are NOT the same as a road race dry sump. You might check into that if interested, I know I did. I just starting looking into dry sumps about 4 months ago from a totally ignorant position, but I'm still learning though. I did call Steve Schmidts drag racing pro engine shop yesterday and that's what they told me too. P.S.- I've built a few engines too. (mostly Chryslers) Can we still be friends?
David- I concour on all, excepting Pat.
