Hi!! I've got an E300TD 98 year 606 engine. I got the head gasket replaced and ever since then its normal operating temperature has gone to 90-95 instead of 80 .... I was wondering if different head gasket types are available, with different thicknesses, in this engine.. like in many other cars. If thats the case how can i tell what thickness was my old gasket and whats the new one... are there any notches or any other mark that represents the thickness? Thanks in advance!!
