Well, to answer #1 above, I just have had too many beers to think correctly. I can use the OPRV Alignment tool that I have, but I have to get the OPRV cover screw out of the oil cooler housing, which is beginning to really upset me. I am going to have to put the housing in place on the block just to hold it, then try to remove the screw...which I hope doesn't lead to disastrous results.
Answer to #2 anyone? All the OPRV's I've seen pictures of look totally different than ours. There are no seals to replace on what I have, unless there is still a piece stuck inside the block.
I have the head torn down and found that the valve seals were definitely junk, but I already have the Head Gasket R&R kit, so I am covered there. However, I do know the head was replaced once before and by looking at the valve seal in the combustion chamber, they did NOT lap the valves. I don't see significant signs of leaking, so I'll leave it the way it is. My question is:
There were two wear rings (not sure what Porsche calls them) under the valve spring seat of the #2 cylinder exhaust valve. Is this normal? Why in the world would you do that when all the valve springs have measured out to within spec? I have a feeling the Porsche Specialists in N.C. just don't have much of an eye for detail...
I still have to clean the valves, springs, seats, retainers, etc., before reassembling the head, but I am hoping to get that accomplished today or tomorrow and will post pictures before assembly to the engine. I have steam cleaned most of the engine, and of course ALL of the parts going back on. I hate the grease stains on the cooler housing and head, but I don't have my bead blaster at the new place, so they are just 'clean'. It also went from being 70 on Friday to 33 today outside. We have two inches of snow on the first day of spring (yesterday)...the garage is cold...it sucks.
Once I get the head back on and disassemble/reassemble the cam tower, I will focus on the vacuum hoses.
Steam cleaning the engine sure does make a difference in it how looks though.
