How a wiped roller lifter is a good thing..maybe

[FWB]

No Patrick no issues at all the sudden stop i believe was the shock that did in the roller lifter.


i want to make something perfectly clear......

"i did not spec out this motor."..."nor did i build this abortion..."

i will not get into who did this or that because it doesn't help anyone.

yet to take out the crank, so actual oil PRESSURE issues i can't verify.

pressure was good on the motor up til i shut her down before teardown.

70 lbs cold, never dipped below 45 hot.

block is a marine block so any oil delivery issues will be reflected in the mains
with the rods the wear isn't a lack of oil, it is contamination. The from where is my question.

once it completely apart, i will torque the rods to spec and see if they are actually round, the bearings to the naked eye look deformed radially, and they are 743V clevite, personally i would not have used them.

Yes it does. Namely the guys trying to help you here for their knowledge base and those in the market for an engine builder.
Since you seem not to want to hold them financially responsible, which is fine, at least make it known who they are and what their practices are when it's all fully determined.

Can someone tell me how much oil (%) is bypassed when the oil filter bypass opens?

I noticed that a lot of filters have what I would consider low bypass relief. We run 35 to 70 psi on our street motor and the filter opens at 8 to 11 psi.

I took the second oil filter listed as an example from Summit. I did notice the first one was a K&N with no bypass. Nice, I'll have to check into that.
