Oil Pressure
#11
Yeah, I was reading some old threads and got scared that I had walked a cam bearing based on others experience. But looking up through the cranks, it looks like the bearings are all in the right place.
My next step it taking the front cover off again. Either tonight or tomorrow.
Is there any way I can check the relief valve? I really don't want to try to work out a replacement if I'm not absolutely positive that the front cover is the problem.

I didn't want to mess around with getting a used timing cover with a chance of it being gouged up and figured I'd break out the credit card and just replace the whole thing new so I could get it back on the road as soon as possible. It's my daily driver.
Oil pump. Possibly broken.
I cleaned the stainer, oil pan, and pickup tube before putting it back together so I can't imagine any debris was introduced. I even ran a bore scope through the pickup tube to make sure I had gotten all the pieces that fell back into it from the old pump gears.

After a catastrophic failure like that I'm leaning towards debris lodged in the relief valve. If I were you I'd be taking off the upper and lower intakes and rocker covers for a thorough inspection. The oil galleys that feed the rocker shafts through the heads are pretty small roughly 3/16" I.D. and plug easily with varnish, paraffin and coke deposits. With the top end open you can pull and inspect your lifters and they're oil galleys for debris. I've never tried but I don't see why you can't get to the relief valve while on the vehicle( only with the front cover on the bench) but before you do you may want to contact BP Utah about voiding warranty if you disassemble. I'm betting there's a chunk of that steel lodged in the relief valve seat.

You can remove them. Just remove circlips.
I took mine apart but after doing do I wish I hadn't. I really don't see how such a simple system (piston on the end of a spring) can be bad unless it is stuck in a position or the spring is broken.

There are two valves on either side of the oil pump. You can see and manipulate the spring for one of them.

Did yours come out easily once you removed the clips? Or is there some trick I should learn?

Oh boy. If that turns out to be the problem, I'm gonna owe you guys a beer or something. I reused the O-ring because I didn't want to wait for a new one and the one that was on there was pretty new. I have two of them now. I didn't think it was that big of a deal. Man, I'm gonna feel pretty stupid.

I can't see how, but I do think the symptoms point to an issue with the valves. I tried to pull the ones out of my old cover last night (just to familiarize myself without breaking anything) but after taking off the circlips, I couldn't get the end caps to budge. Maybe the o-rings are just gunked up.
