stee3 Member 194 Member For: 15y 3m 5d Posted 23/01/14 06:10 AM Posted 23/01/14 06:10 AM (edited) Crow valve springs with Crow retainers are not a good combination. There is known issue with them, to get the correct spring pressure they have recessed the collets further down into the retainer. This is a big issues on the exhaust side as the valve stem is slightly shorter which brings the retainer higher which then makes contact with the rockers arm. I have called them about this and they played dumb. Have seen this so far on 7 engines so far. Edited 23/01/14 06:10 AM by stee3 2

stee3 Member 194 Member For: 15y 3m 5d Posted 23/01/14 06:33 AM Posted 23/01/14 06:33 AM They would probably recommend them with the factory retainers. Its the crow retainers that have an issue not the springs. 1
