CP piston pins getting blue
Hi,
I tuned a RXP 2006 and built in CP pistons and Carillo rods. Now Iīm getting the second time a piston failure on the last cylinder and found out that in both failures all 3 piston pins went blue on side due to overheating. Has anybody seen this problem before? I was thinking that possibly the piston bottom cooling is not working but I cannot see any problems on the jets or oilscrews.

sounds like you damaged the oil squirters
they spray oil on the pins

Make sure you have the correct oil squirters for the correct engine year

I wonder that the pins are only blue from overhaeating on one side.

Is the oil pressure different on the sprayers , should be the same ?

The wrist pin could be too tight. Binding up the Piston. Had a customer who was building his motor and they were so tight that the piston wouldn't float or move on the rod. Ended up just honing them a little to free them up

Couple of pictures of old versed new piston squirts.
Sitting on a magnet to keep them straight.
the outside ones are from an 06 GTX limited (215)
the middle is a late model one. the part number suits a 2012 model RXTX260.
I don't have a number drill set so could not measure any difference in hole diameter, in the flesh there's no noticeable diameter difference the chamfer is an optical illusion. One thing for sure the spray angle is different.
From my understanding the squirts main function is piston cooling not pin lubrication.
