Back to the installer for warranty work and he discovered #7 and 8 with verticle scoring in those two cylinders only. Back to Roush and it's been about two months(guessing). I'm no expert but it seems these motors aren't highly stressed even though it's over 500 hp. How hard is it to build a motor and have the rings seat? Apparently kinda tough. Has anyone heard of Craft's motors puking oil? Seems Craft will get my money next time! 209

209, I had a Roush 402 and it did exactly the same thing! A quart of oil every couple of hundred miles. I ended up sending it back under warranty and whatever they did, it doesnt use any oil now. Just the hassle of getting it removed, shipped back to them and then re-installed.
Yes they fixed it but I agree with you, most engines are not overly stressed and one would think that Roush, someone who deals with performance engines/parts all the time would get it right. My car probably isnt driven that much harder than my daily driver and even if it is driven hard, the engine should be able to take it.
Maybe they have some kind of in-house training program going on or something.
I'm also wondering how good the Craft engines are or even ones from Enginefactory.
