Just had chance to properly check the head and block, all looks ok so I can now breathe again, while it’s head is off ,I’m going to do rod shells,, pull one of the piston out and check end gap on top and central ring,if they within bmw spec they will be staying in, I’ll be disappointed if they are out of spec on a 69500 mile engine, but from what I worked out on 100k motor, I recon they should still be inside spec
