Someone may have covered this before? The cylinder head inserts ( copper?) on my '03 5KE have
Sunk below the level of the alloy head instead of sitting proud, it is now burning inner
Cylinder 'o' ring. Has anyone found this problem before? Mine hasn't done a great deal
Of mileage. I had a similar mod done to my TZ B with brass
Inserts and never incurred this problem.
