3sgte head gasket Options

[rjbibeau]

hey sup guys i'm helping my girl with her sw20 3sgte project. we just pulled the head off the engine yesterday because it blew a gasket and well it did and it was in the 3rd cylinder. first question is...there is a streak of corrossion from the coolant that leaked into the cylinder on the walls and i tried getting it out with some wd40 and it's barely coming off. it's a raised corossion. will it hurt the rings if i can't get it all off or will it be allright. next question is we put the crankshaft at tdc and when we took the timing belt off the right cam as you look at the timing side tweaked back a bit but the left was just fine so i'm like crap so i look at the mark on the cams and the left cam is deece but the right one is a lil off from the marks. when i try to turn the cam to correct it..it seats back to where it was beacuse the valve springs are forcing it.

when the engine was in the car it had a wierd shutter sound kind of like metal on metal when it was under load from like 25-3500 rpm but then went away as the rpms increased, i figured it was a idler pulley problem but i checked em and the looked fine. there wasn't any slop at all in any of the pulleys. could that one or two degrees of being off in the timing belt cause that type of sound. there were two yellow marks on the cam pulleys and thought maybe someone else was there doing a belt job.

now for the timing tensioner that is such a wierd tensioner i understand i need to compress it with a vise and shove a pin in there and install it and mount it up and pull the pin back out like a grenade for it to retain tension. could the timing tensioner be going limp when it's under load and the #1 idler puller be slapping itself on it's mount.

any input would be appreciated.
