if I take the head off and it's been rebuilt recently do I need head work? Cuase I'm told it's gonna cost 300+parts+machine work... and my turbo needs a rebuild, I don't want to just throw money away esspecially when I just had the head done not 2000 miles ago. When I took it off the shop owner told me to clean it, when I did the "lifters" (little round metal caps) fell out, I have no idea the order in which they go in, how screwed am I? Who sells a gasket "kit" that includes an mls headgasket?
