Duke thanks for your very good and detailed explanation about compression. We know there are many reasons for low compression as (leaking valves, deposits, worn rings,head gasket, etc.)
And from your explanation of compression, there are various factors that influence these numbers at the time of testing, but when are compression numbers considered on the low or even the high side. My total average is 174 or 12.3 and as you said all the cylinders are fairly equal, but the girl has been driven?
I cannot find the MB's recomended compression numbers, does anybody have these numbers?
Thanks timreid
