I'll post some photos as I get them, I've always enjoyed perusing the forums and appreciate those who include photos with their posts. I figure I'll start a new project thread when I do.
In regards to the oil control rings, I'm still undecided. But, it seems like new OE rings would be most cost effective for the goal of a refreshed daily-driver that provides peace-of-mind. I've noticed the same thing you've mentioned, options appear limited to new pistons with rings and conrods (e.g. CP or JE and Arrow or Carillo). Seems kind of excessive to replace pistons (~$1000-1100) and rods (~$1100) to fix the oil consumption issues known of the m54. At those prices I'd rather rebuild my s14 to get that thing running.
Agreed. Besides the machining work and timing, it appears that the rest would be relatively straight forward "wrenching," and adhering to torque/torque+angle, and clearance parameters. For the top end, I'm thinking at a minimum valve job and new valve seals (in addition to machining), and for the bottom end: rings, rod bearings, rod bolts (if they aren't spec'd to be reused), gaskets/seals at a minimum. I haven't read much about the main bearings being an issue for the M54, I know they're typically not a problem in the s54.Originally Posted by Sockethead
Right now, my plan is first to pull the engine and start disassembly. Then inspection for cracks and measurement of straightness (head and block), as well as continued research for options and solutions (e.g. machining, tolerances, torque specs, parts). Also, I'd like to find a machine shop in southern California (Orange County, specifically, but would venture out to LA County) that has experience with BMW heads/blocks (ideally with the m54).
As always, I'm open to your perspectives as well as any guidance and advice from your experience.
