See attached the results of compression test on a 2004 BMW Z4, E85, with 2.5, M54 engine. 126,000 miles. The engine was dry and cold. The pictures are labeled with cylinder number. I thought I would post this. The compression test is a simple test and not too time consuming. Remove all the plugs and pull the fuel pump relay. I bought this car recently and wanted to check the compression before proceeding with other repairs.
Oh my the water pump, there is a support frame directly in front of the water pump, so you must loosen the left motor mount and slightly raise the engine to get the water pump out. Clearly an oversight, I think. At least it has an electric radiator fan, so there is nothing mounted to the front of the water pump. Cheers!
