Had car for over a year now (2008 170TDI S-line SE). The cars had new oil/coolant pump supplied by the Honda Dealer when i bought it, as apparently it was bypass before that, the system was flushed 2-3 times when when i took it back and the Honda Dealer said it'll be any remaining oil within the system....??Just had it MOT'd and serviced a year on and the oil is still mixing in the coolant tank, had it flushed out again yesterday to see if it continues. The car seam to run fine, could there be an underlining issue with this, the chap who'd just serviced it said it could be a possible cracked head if the coolant doesn't clear (££££££). Does anyone have or had similair issues.Like to know what other people on think if its a cracked head is it worth hanging on to the car and forking out some cash or could it be time to move it on?
