Hey I’m back again with a little bit more problems. So I replaced the cylinder head and everything to do tmwith cooling the engine.( had a Mini Cooper specialist shop do it) I finally got the car back! I definitely missed it a lot.. car is having some problems post-surgery. I have a misfire on all cylinders and another code showing low oil pressure. Oil holds fine in the car when driving but idle is no good! I would greatly appreciate some ideas and knowledge regarding this situation

 

"what year is the car? is it S or non-S? mileage?"

I just saw your other post..lol it is 09 R55 S.

did you ask the shop to find out what happened?

can you check the timing? Some people still think it should be set at TDC with 1st cyl on compression stroke which is WRONG.

do you see oil coming up the cyl head?
