  1. Engine has a Dynatard, recent oil change with good oil pressure and good power. No wet stacking, runs and sounds good. Has a little vapor out the breather. The original owner told me he had his local Mack dealer put in the crate motor complete because the original had cracks in heads.

  2. Have a '85 RW with an E9 I recently bought. The story I got was that the engine was replaced with a Mack crate motor around 1994, and the truck was used very little, maybe 10,000 total miles since then. I'm getting a lot of oil out the breather, underside of the truck gets wet with oil. What does everyone think? What are my options?

  3. I use PPG acrylic urethane for metallic and solid color basecoats, and clearcoat everything. You can wetsand and buff the clear for an outstanding finish, and buff again later for minor surface scratches that appear. It's also much easier to repair your basecoat if you have a clearcoat to blend to. I use this method for farm tractors, cars, and trucks.

  4. I have multiple packing leaks on the exhaust manifolds and exhaust manifold piping on my '85 RW with a '94 E9. The manifold -to-head gaskets aren't leaking, but all the doughnuts are. None of the manifold bolts want to break loose. Anyone have any suggestions on getting them out? Looks like trouble.

  5. I recently bought a 1985 RW with the E9. The air compressor seemed to run continuously, and the relief would blow down air. I adjusted the governor so it bypasses at 120 lbs by the gauge. With the truck running at 1000 RPM, when the governor bypasses, within 50 seconds, the pressure will be down to 100 lbs, and the compressor will pump back up to 120 lbs. in about 45 seconds. Then this cycle continues. I can hear no air leaks when the truck is running, and there are no leaks or loss of air pressure when I shut down the engine. Is this normal? If not, is it the governor, or something in the compressor?
