Markings on my pistons
Posted: Wed May 22, 2019 4:48 pm
Hi
I took a borescope to my cylinders this evening and found some markings on the pistons. A bit vague but one mark is "20" (in Cylinders 1 and 3) and I see "QED" in Cylinder 3 (not surprising as the engine was rebuilt by QED in the 90s).
I don't suppose any conclusions can be drawn from these? 20 thou over bored perhaps? If so would it affect my choice of head gasket?
