May Need New Heads - 2001 Monte Carlo 3.8
My 2001 Monte Carlo was using antifreeze and blowing white smoke out the exhaust. I had the plenum, upper intake manifold, and lower intake manifold replaced a couple of years ago. I tore into the engine and removed the heads and all of the gaskets looked good. No. 3 piston is considerably "cleaner" than the rest which leads me to believe that was where the anti freeze was leaking. My next move is to buy rebuilt heads or send them off to a machine shop.
Here'* my question! Should I send the heads out to a machine shop and have them repaired or buy some from NAPA for about $300.00 each?? I don't have any idea how much a machine shop charges or if they can deal with a cracked head, if that'* the problem. I can't think what else it could be. I've never bought rebuilt heads before so I don't know about the quality of rebuilt vs.the local machine shop.
