You going to freshen the new/ used engine at all, or just plug it in and hope for the best? I'd sure be thinking, new head and intake gaskets(at the very least) while it's out. Who am I kiddin?? I'd do the oil pump(probably the whole bottom end) , water pump, timing belt, and get a new EGR tube. Now's a real good time to mount a tranny dipstick as well. Doing all this, won't cost but a few hundred bucks, and a day or two. Could even buff an' polish those intake runners, and toss that dopey plastic cover (as frustrating as it is...engine failure is almost always opportunity thinly disguised:bwgr![]()
