Lauren Posted May 18, 2017 Report Share Posted May 18, 2017 So pulled the head on the mini Cooper today. There was zero compression in cylinder 2. Previous owner said. Loan headgasket. This is what I found. Good thing I have a spare short block on hand http://i231.photobucket.com/albums/ee254/ca18det007/Mobile%20Uploads/0518171633_zpsjw7hwtsq.jpg http://i231.photobucket.com/albums/ee254/ca18det007/Mobile%20Uploads/0518171633a_zpsboqqmt7c.jpg http://i231.photobucket.com/albums/ee254/ca18det007/Mobile%20Uploads/0518171633b_zpsdnpuk89j.jpg Quote Link to comment Share on other sites More sharing options...

Geeto67 Posted May 19, 2017 Report Share Posted May 19, 2017 So what do you think did that in? Overheat? Detonation? Quote Link to comment Share on other sites More sharing options...
Lauren Posted May 19, 2017 Author Report Share Posted May 19, 2017 A tune designed for larger injectors and ran stock injectors , an aggressive under drive pulley on the supercharger and a coolant leak that was never taken care of and let car overheat.

Lauren Posted May 19, 2017 Author Report Share Posted May 19, 2017 The mini is really easy to work on and it's pretty simple overall. In service mode everything is accessible. I bought this car knowing it has a "headgasket" issue. I have no money in the car yet. I wasn't expecting a bottom end issue but at this point it really isn't that much more to pull the bottom end. I will have a fresh engine go back in it next weekend. This time it will be built to handle everything I can throw at it Quote Link to comment Share on other sites More sharing options...
Geeto67 Posted May 19, 2017 Report Share Posted May 19, 2017 Is it really a "bottom end" issue? The cheap as chips hack in me thinks it is a dingle ball hone and a used serviceable piston away from running again. maybe it is because I consider bottom end to be rotating assembly (crank and rods) and this is only slightly worse than a ring job - but what do I know, the only engines I have ever touched this far apart are old junky American v-8s and 70's motorcycles, not boosted modern german precision engines.
