    Wow. So I should just buy the heads,can,intake,head gaskets, ARP head studs, intercooler and everything else I want and just put on the stockshort block? I have a machine shop here that does all my machine work and I only spent about 600 on a ford v8 that was decked, stroked, balanced,bored, line bored,etc....

    thats all well and good just not necessary in the 3800 world. the bottom end is like a tank in these motors. they just dont fail unless you **** with them or the LIM gaskets go and the coolant takes out a bearing.

    WhenWhen I bought car 5 years ago lim was leaking and had water in oil. Looked like peanut butter smeared in the engine. I went ahead and did head gaskets and poured 2 some diesel in oil pan to clean out and changed oil 4 times in first 1k miles. Car had 142k then. Now 173k and rod took a dump. My guess is the 13psi wasn't good for bottom end. Car usually makes 10.5psi. I also think that I may have had gas in the oil cause when I took supercharger off the lim was wet with gas. And 3 injectors were wet. Believe that's where my fuel mileage went down the drain is from 3 leaking injectors.

    This is most likely what did in your engine. The fuel sits in the cylinders and eventually leaks past the rings and into the block.

    Yeah. I'm a mechanic for a living. I've been a Nissan master tech for 5 years. Now work at a independent shop working on all makes and models. Hope my new engine has good injectors. Will do lim gaskets and maybe swap my heads and sc.

    You know that 6200 isn't the best thing to be doing on a motor with oiling deficiencies?
    I drink..so consider that when reading my posts.

    I did the cam heads and headers at the same time. It made a big difference.

    S1x is a good cam. But if you are pulling the heads off, you should go is3 or xpz.
