AmazonAt the end of 2020 the engine came out again so Adrian and I could fix an oil leak and make some improvements. The first video is taking it out and up to Adrian's.
Diagnosing the oil leak
Tearing the engine down to find the oil leak, which turns out to be the wrist pin seals, and adding an air compressor while it's out.
Injectors, cam rollers and oil pressure
Adjusting the cam rollers, replacing the oil pump regulator springs to bring the oil pressure back up, and how the injectors work.
Assembling the engine
Reinstalling and shimming the oil pump, and a new oil pickup for the deep sump.
First start of the 4-71
Final assembly, then Adrian sets the injector heights and valve lash and we fire it up.
Finishing touches
Finishing the engine and painting it ready to go back in the boat.
Back into Renko
The engine goes back into Renko, then a new exhaust, alignment and starting it up.
