Fuel System & Lines
The rear door seal has been replaced on the outer side the inner door needs to be completely pulled out of the Chinook looks like welds need to be broken.

Hot side can be plugged into the regulator and cold side can be electric pump facing. May 3D print a separate base for the […]
Engine Rebuild
The engine is back from being bored, pistons and rings in hand. Identifying work that needs to be done on the transmission. Assembling the low and top end of the engine. Cleanup of bell housing and oil pan. Clutch kit is on order.
Engine Transmission Pull
With a cheap harbor freight hoist the 20r engine and R43 transmission have been pulled. The block crank and head will be taken to a local shop to get bored honed and rebuilt. Cylinders didn’t look to bad for 80k miles. Since the Chinook had a blown head gasket, my guess is that it overheated […]
