I finally got around to taking a compression test on my e36 with the M50tu that took convincing to get running, but now won't idle. So in the Bentley is says compression should be between 145-156 but im reading much higher. The compression test while it was cold showed (in order), 210-210-200-230-200-205. These numbers are already pretty high, especially that 230 on number 4. Then i let it warm to operating temp and got 230-235-235-235-220-225. Wow, these are way higher than they are suppost to be, or am I wrong. Could I have lucked out and this thing already be built up, or am I being way too optomistic. If it is built up, do you think the stock DME i put back in it could be the probelm? At least i dont have a bent valve or anything from those readings. Any idea of what could cause them, thanks.
