    Cleaning Parts?

    Getting ready to put the new motor and tranny together and in the car.

    I was going to install the turbo intake piping, but I noticed the inside of the tube has a light coat of oil. Same thing on the inside of the intake manifolds. On the lower intake manifold, the ports have varying amounts of oil coating. I thought it would be a good idea to clean them up, so I had my mechanic use his parts washer. It cleaned up the outsides of the manifold but he said I need them steam cleaned to clean the actual intake ports.

    Is this normal for pcv valve equipped engine? Will this affect anything, or is it only visual? If it is a good idea to do it while engine is out, what kind of shop would have a steam cleaner? I called the radiator shop thinking that was a good bet, but they don't have one…

    Well, I ran a rag through the turbo up-pipe. That took care of that. And if anyone is wondering about cleaning the intake manifold, go to a machine shop. The local little shop is puttting them in a tank over the weekend for $30.

    Believe it or not I use Orange hand cleaner as my degreaser, dilute it a little bit with water and put it in a big container and use a brass wire brush. everything comes out squeaky clean. Works on turbos, intake plenum's, heads everything.
