WTF? Dude, I hope you're not the one building, or doing serious repairs on engines at your shop. :nono" Another WTF? No RTV (silicone adhesive) needed. It's a better idea to replace the head on this application. Chances are that the engine you get will need a head gasket, if not now, soon. The bottom end of those engines are usually good to go for a LONG time. The only other problem I've seen on those 2.2's mechanical is the timing chain tensioner failing, and sometimes a timing chain. I replace them all together anyway. The only thing I can agree with this tool 100% on is changing the plugs while working on it. Use AC-Delco plugs. I am not going to try to claim to help him out other than on advice. I'm not on OR to get business for the shop, but I can let people know that I do this sort of work! If the OP wants to consider the shop where I work as an option, I can PM the number for him to call for an accurate estimate. One other thing, there was one of these S-10's that I worked on that had a cracked block. It was cracked down the bore, along the travel of the piston. I've probably done 20-30 of these in the past couple years, so I know a thing or 2 about a thing or 2 on them.
