I have started a very mild build on my '85 K20 diesel Suburban, when I bought a few months back the transmission was bad so I sourced a TH400 to replace the 7oor4. The rear seal was leaking and I just pulled the engine so that I can replace all of the gaskets in one shot. This thing has more oil leaks than any vehicle I have ever owned! It took 2 hours with a Sioux steam pressure washer to clean the engine bay and front end, and another 30 minutes on the engine. How do you get oil behind the headlights?! I tore into the engine and previous owner was in it at some point, and they must have owned stock in gray RTV, look at the picture and see how much restriction the silicone caused in the water pump passageways. Hopefully I will have this thing back together and on the road by the end of the month, I will be too busy to work on it again until July if I don't finish it by May 8th. Enjoy the greasy pictures.
