    Hi MiniToBe

    I saw your name referred for advise on engine rebuilds.
    My R53 engine is toast. I haven't totally ripped it apart, but it looks like the piston rings are gone on Cyl#2 Engine oil is boiling, no compression on Cyl#2
    I'm thinking of rebuilding the engine. You happen to know how much it will cost if I have a shop do it. I was thinking of going with reinforced pistons, connecting road and a big valve head.

    Thanks for any information you could provide.

    Hello MTB,
    After purposefully inspecting the wiring harness on my R57 that runs best when intake cam sensor is unplugged, I’m pretty certain the harness is not the issue.
    Again, with intake sensor plugged in and at intial start, runs and idles/revs fine 20-30 minutes. Moving the car, running in gear, runs like crap. Likewise, after shutting down and restarting and being plugged back in, idles and revs fine as above after start. If then shutoff and restarted, runs great for 2-3 min then runs like crap until intake cam sensor is unplugged.
    I guess I need to buy a used computer and have it flashed?
    You mentioned a Comp Tech, could yougive me an idea how this works/ cost etc. I’m old school and use to just replacing burnt out capacitors or buying test good used computers that were plug n play. Any insight would be greatly appreciated.

    Hi MiniToBe,

    I've been lurking in the forum for awhile and you seem to be very knowledgeable with N14 engines.

    I have 2009 Cooper S at 107k miles, with 9 psi compression in cyl #3. Other cylinders show ok compression. Apparently burnt valve in #3 (I hope). Dealer did diagnostics and told me it's $12k for new engine. I rolled out of the shop laughing. Other than sounding like Triumph motorcycle, it actually still runs relatively well with the rest of it.

    Anyway, I've planned to pull off the cylinder head to evaluate the damage and to see if pistons are still ok. Any thoughts on whether I should buy remanufactured head with new valves (I've seen them priced between $1200 - $1500 online) or send this head off to somewhere to be rebuilt?

    What else I should be looking to replace while "there"? Any pro tips what to take into account before beginning to do this? I've seen various combinations of "gasket kits" online and I'm a bit confused which ones I really need.

    Thanks!
    Juha

    Would you be interested in taking on the repair if I was to get the car to you? Just curious!

    They shipped out the FRM. I hope I get it by this weekend. If not then I suppose I will need to wait another week. I can surely still use your help once I install it. I have all the apps needed but I still don't know how to use them well.
    Not sure how to update the SP-Daten still or how to even change the VO on the module I get.
