nano Posted October 17, 2015 Share Posted October 17, 2015 Hi, today I removed the head of my 4e for maintenance. Anyway I have a question concerning pistons mark.OK on cylinders and pistons number 1 and 4, its written "2" and on cylinders and pistons number 2 and 3, its written. "1"Does this mean that the block is not stock? If I want to put New oem pistons, I must buy 2 pistons mark 1 et 2 pistons mark 2? I M a bit confuse about this.Can someone explain me how it works, thanks Quote Link to post Share on other sites

5e colin Posted October 17, 2015 Share Posted October 17, 2015 that means the correct piston is in that bore as it should be or am i misreading your question ?? Quote Link to post Share on other sites
nano Posted October 20, 2015 Author Share Posted October 20, 2015 Ok, no I thought that cylinders had the same bore, either 1,2, or 3. Thanks Quote Link to post Share on other sites
