Has anyone done an engine rebuild yet? Anyone install the Motorsport 2.5L kit? What's the typical cost for both parts and labor? I have an 88 (orig. owner) with about 215K...my idle oil pressure is very low (15-20psi) and the t-chain rattles more than before, so I think it's about time this old baby maybe ready for a rebuild. Is so, I might as well go with the 2.5 kit. Thanks for any input!
