before installation of the Boxster S cylinder heads, I discovered that two of the cylinder head bolts were cracked. during cleaning, I noticed a 'nick' in the shoulder of the bolt, but upon closer inspection I noticed a hairline crack extending toward the shank and up toward the top of the head of the bolt. one bolt came from one head, and one from the other. I wonder if this condition could have lead to the cracked head -that is, could this cause the bolt to loosen, and cause fatigue? Unlikely, but I must admit that seeing two cylinder head bolts with cracks in them does not make me comfortable. What does this say about Porsche quality?
