recently traded in my trustworthy 300 tdi for an 02 td5 D2, has 133,000 on clock and a good service history, had it 3 months now, for the first couple months oil level didn't rise, now not sure if its coincidence but a few weeks ago I replaces injection harness as I had small amount of oil in red plug, I had poor towing performance so did the harness in the hope of rectifying that, anyway checked oil level today and it was a good quarter inch over the full line and smells of diesel, no other symptoms, no smoke, no lumpy running, never overheated, have googled it and narrowed it down to two things either injector seals or porous/cracked head, obviously I'm hoping it just the seals, what are the chances of it being the head?
thanks
