I really, really wanted to do both of those things but in the end did neither, as time and funds stipulated that I couldn't. I thought I had a spare one piece shaft but I guess I used it, and I considered replacing the nylon piece since I have some but there just wasn't time. I did use 6 cans of brake cleaner while scrubbing the engine though...With the pan still off and if you can afford it. Get the M55HV with the steel shaft. Those gears in the oil pump worn by now plus probably pitted up with all the lifter wear.
The nylon connector probably long gone or soon will be. O'Reilly's had the steel for about 10, the pump around 35 ish. With all that metal, new screen and pickup also.
I would pull # 1 rod cap and # 1 main. Just look at bearings see how bad they are or if ok.
I'm afraid the coming update won't be as impressive as I'd hoped since I had to make many compromises and flat out abandon things I thought I had completely planned out. Every single step I took on Thursday was a struggle and nothing went right at all, probably because I said it would go smoothly. And it was my most productive day of the entire week. Despite the tribulations I managed to get everything together with the exception of the exhaust system, and hope to break in the cam tonight after work. It was too late to run open headers when I finished up last night.
