I have no idea. I stopped logging hours. I'm out every weekend in the summer and many weekdays as many here will attest. So let's do some math. ~35days/year x 2.5hrs/day x 9yrs = ~787.5hrs holy s#it that's a lot.

The oil temp is between 140°F-170°F delivered to the bearings after the cooler depending on how hard I am running it. Block water temp is 135°F-160°F.

I'm looking to switch to 0w5 Wolf head.

And I do run Mobil 1 302 oil filters or Purolator Pure Ones.

Awesome results. I wouldn't change a thing other than changing the oil at the end of the season.

Looks good. What happened to your valvetrain?

I don't know exactly. I keep gaining lash on my cams. Rocker got loose, walked and bent a valve. (My neglect I heard it naking noise that day) I switched out 252/264 solid cams to ~235/241 hydraulic roller cams that I do run solids on. This particular engine just seems to beat the snout out of my valve train. Adjusting lash 3-4x a summer. My old solids I would check every summer and adjust a thou hear and there. I'm working with my head guy and I think I'm just going to throw in my old solid springs lightened up a little.

A buddy of mine was running solids on a hyd years back. Out of the blue one day, his polylock broke on the exhaust valve, rocker came off, blew the headgasket into the lifter valley.

In a recent conversation with a cam grinder, he had advised against running that setup. He mentioned how alot of people assume that a hyd has easier lobes than a solid, when in fact it can be the opposite. His advice was if you wanna run a solid lifter in an endurance engine, run a solid roller endurance lobe profile. I was contemplating going to solid roller lifters to avoid the pitfalls of alot of the hyd lifter issues, but after talking with him, decided to stick with what i have.

Did you notice any abnormal wear on the lobes, or valveseats Jason?

I only spin them to 5600-5800 now, so maybe I'll just throw in a std set of Morels in and see what happens.

Never liked the stupid solid roller lifter on hyd roller cam deal anyway. Too little lash, which you need to do to make it relatively happy.

Nothing but a buzzword (from cam grinders/pickers) to look different.

But, I'm the azzhole for going against it a bunch, some years back. LOL.

Be gone with it and get proper lifters for the cam.

what are your on the seat&open pressures?
