    250 PROXS Question

    I had my 2014 250 PROXS compression check. All cylinders checked at 90. The technician checked the engine when it was cold, Shouldn't it have been at operating temperature? Motor has 229 hours.

    See the FAQ at top of the forum for the correct compression test procedure, print it and request your "technician" reaccomplish it at no cost or refund your money since you paid to have one done correctly and didn't get what you paid for.
