the problem is certainly that its a mini

I agree lol

He has a charger now

Trying to get the mini running so my cousin can use it.

My concern is if he flipped the connections on the battery, if it could have fucked up anything electrical?

I picked m head up from the machine shop. Final verdict is 4 slightly bent valves from unevely cut seats caused by the previous machine shop. They think the pervious shop's pilot may have been bent and the only reason it stayed sealed for so long is the pressure from my beefy valve springs. I re-shimmed all the solid lifter buckets last night, only took 2hrs this time. Gonna assemble the rest of the head tonight. My nephew has been taking auto shop and wanting to learn about cars so he's gonna help me get it back in and running this weekend. If we get done soon enough maybe ill have him hit the buttons on VE Analize live to get it in the ball park before the dyno tune.

sucks about the shoddy machine shop but glad its going to be sorted out

Thought I had already made a post about this. 2005 mini cooper s, r53, or whatever. My dumbass brother flipped the connectors on the battery and cranked it, something in the front smoked  I checked all fuses, everything seemed legit? I'm thinking starter?

likely suffers from a faulty starter motor, a dead battery, or an immobilizer (EWS) issue

Did a leak down test, 20% leakage through the intake valves, pulled the head to see if I could lap them in but was not successful. The head is at the machine shop getting the valves and seats cut. Should only take a week or so. Then back to all the checks before dyno tuning.

I wish,  it's either a valve/valve seat contact issue or weak valve springs.

Finished the valve adjustment and thought id check for boost leaks with the cam out. The fucking intake valves are leaking,  guess the head is coming off.

Does that mean another 40dollar bucket shim kit again?
