I already have someone who can build the pistons, which is why i needed to know if the c/r was in the pistons or else where (head gasket). I want to get the compressio to 17.5:1 that will allow for future changes, I also live in Arizona, so I dont have to worry about the cold weather starting problems
the 7 thousands of an inch was measured in the shop vs the spec sheet on the 1.2l tdi piston, here is the copy of the pdf found on page two of idi to di threadhttp://www.katech.re.kr/bas/sta/Upload/Board/TBL_ANAL_PART_000396_1.pdfthe reason you cant swap piston and rod is because they are a trapezoidal fit, not normal. (ill get you that picture as soon as i can) I also live in Phoenix, arizona, no prob with altitude, just heat. (no a/c)I think i have figured out the reasons as to why no one is able to get any used parts from this engine. because of the streach bolts that run all the way through it (head to main bearing) if you remove the crank shaft, the block deforms out of shape, rendering the block usless, so there is not too much you can do with the block to strengthen it, only replace it at that point.
