M104: Gasket Replacement P.3

Head straight off the engine - flipped it over to check for cracks. Thankfully, there were none.

Cylinders 5 & 6

Cylinders 3 & 4

Cylinders 1 & 2

Block after head removal

All the old exhaust manifold studs had the nuts frozen on to them. So putting each stud in the vice and heating up the old copper nuts with a torch helped get them free. Working them back and forth slowly with WD-40 getting squirted on them made life easy. Got the new copper nuts on and they sure look good.

Head completely cleaned of sludge and all the grime. Sludge was blocking many of the oil passages and even the return at the front of the head. Was to the point where oil would be able to pool and not drain correctly from the head to the crankcase. I'm willing to bet this lack of drainage is what sped up the sludge.

 Nice and clean.

Close up of the new copper nuts and new updated exhaust manifold gaskets.

Going to do a better job of cleaning the block tomorrow and the head will be ready to put back on. Excited to get this car out of the garage and back on the road. This engine won't need any work outside of oil changes for a long time to come......... Hopefully.

  1. I think you have the two photos for cylinders 1/2 and 5/6 backwards.
