Robb Mc Rob thanks for the info. The guy you are talking about has not read the thread yet
I was asking about running titiaminium valves on the street and for autocrossing and road racing. 3 major makers of the valves said no. Heat cycles and they pound the valve seats out. You know I found the missing link that has been running them for almost 10K with no problems. The only thing that might help would be thermo coatings on the stems. The seats are a special material extra hard. I guess the saying works, you get what you pay for, nothing extra.
I thought that some of the roller rocker companys would have a rocker with an
oil port through the adjuster and into the roller body to drip
oil on the bearings. You would need hollow push rods. The splash idea is good but direct oiling is better. Rob with no
oil pressure for a short time the roller bearing are going to get pounded and the surface they are on will get the same. They will last a little longer than a ball but the ball will not put 20+ little 1/16" harden steel pieces in my motor. I don't have screens epoxyed in it. I other point is that under .600" cams the hot thing is thes beehive springs from comp cams. I am going to try a set myself. Have also heard they don't work and some have broken. The whole story is yet to be told. GM has be running these spring for 6-7 years. Have seen 2 broken springs against how many? I have just resealed a motor with 187,000 miles on it everything is in great shape, springs are soft but oil changes every 3K. Motor is clean inside. Got to go Rick Lake
