Spare M42 refresh/rebuild

[brads2002]

How is this coming along? Thinking of refreshing mine over the winter. Going to place a call to Metric Mechanic to inquire about their kits.

I too eagerly await completion of this build, and would be happy to help swapping the engine should it be needed.

Any updates?!

where'd you get the crank from? If BMW themselves for that price I know what I'm going to do

I got mine from the UK, private seller. Through BMW they're $1200. I'm not sure you could get one since it's a "euro" part.

Only I don't want an M20. I'm happy with the M42[emoji1]

I wasn't trying to say you should have done an M20, just remarking on how your convenient tabulation confirmed my previous thoughts.

Still need rings, bearings,pump rotors? Thermostat, water pump, and the misc engine gaskets. Yikes... that thing got expensive quick

Just need bearings! I have everything else

Cripes. Looks like I was right when I did some back-of-the-envelope stuff and determined I could build an M20 2.8 for less than a M42 2.0

Cool build, I am liking it so far!

As someone with a 2.1L M42, I can tell you that you are going to like running that M47 crank!

Thanks! The only thing left are the pistons. I have the S52b32 pistons, but I'm having a hard time finding someone to machine them to the specs I want. I may just get a set of pistons from MM, JE, ect....

Nice work! One of my next projects is to address oil leaks from the timing cover. I'm debating whether or not just to pull the engine over winter and spend a month or two refreshing the engine. Though maybe I should just find a spare engine like you did. :)

Hmmm, maybe I should pick up a crank and give it to them since its still fresh in their mind, lol
