Mr P:
I hope to get time to look at the bearings this week.

I run Yella Terra 1.65 rockers for about 5 years now on two different sets of heads.

I had not run the motor hard since the cam swap over the Winter. I had put about 4 hours of cruising time on the new cam/lifters and then I changed the break-in oil over to 10W-40. On that first drive on the 10W-40 is when I noticed the oil pressure change during the drive. I just got done with a half throttle hit and then came to a stop sign and I noticed the oil pressure going down. I was actually getting ready to make a WOT hit and that is when I looked at the guage. I slowly made it back to the garage with no extra engine noise. The gauge was showing 25'ish while cruising back to the garage. Ever since this time I have been showing 38'ish on cold startup and then it creeped down to 10 or less at warm idle. Then I started pulling it apart.

Thanks!
