Ron,
I've heard of different versions of EA-81 heads, one with two "hidden" head bolts
that everyone misses - or maybe that was to separate the crankcases? That's
all I know about that. I can check the manuals I have for more info. I took
mine off with no problems so this doesn't sound right. Maybe a picture of the
heads? My PC is still in shipping somewhere so I haven't been on email and don't
have a place to receive pictures yet, but I'll get back to you after I check
whatever info I have.
Good luck,
Gary

*October 28* UPS dropped off the heads from RAM and all other work
stopped to resume the engine assembly. The carton that I'd sent was
returned in good shape and would have held up well a few more trips if
necessary. The engine was checked for clean mating surfaces and the
gaskets were slipped on. The heads were then slid on the studs. Torque
sequence for the bolts in the Subaru manual suggests a process that
includes the rocker bolts and would require a special wrench to clear
the rocker tube. Don Bochard's tape on rebuilding the Subaru had a
different sequence tightening heads first and rocker bolts second,
avoiding the problem. The torque sequence for the top four 17mm nuts are
4, 6, 5, 3, and the bottom three nuts are 1, 7, 2. The stages of torque
are 22 lbs, 43 lbs and 47 lbs. Then the rocker bolts were added and
torqued at the same values after the heads were done. I added pictures
to the site in case someone needs help with a heads shipping container.

Ron,
There should be 7 nuts if you count them. You could almost count the
holes in the first link picture above.

Same here. Works great for over 200 hours now. I never liked sucking
that nasty heated air back into one carb anyway. Warmer, thinnner, air
on one side sure seems like a way to imbalance the carbs. Just vent it
straight out below the firewall. No special valves required.

Yup!
I run my vent from the valve cover to exit at the lower left corner of
the firewall (looking forward).
You'll get a little oil splatter occasionally but its no big deal.

Frank,
I've already done this to the pass side elbow, but the pilots side elbow
has the brass fitting threaded into it with a hose coming from the valve
cover.
Can this hose be simply vented into the air and not the plastic carb
intake?
Thanks,
Kelly

Your right, the more I thought about it the more I realized returning the
line to the carb intake was a dumb idea for all the reasons you just stated.
I've now re-run my line to below the FW, and trashed the elbow.
As a side note has anyone ever noticed all the plastic shavings and fine
chips inside these plastic elbows from the machine work done on them. Would
have been nice if Stratus would have at least blew them out with an air hose
before installing them on the engines.
Thanks again for the tip!
Kelly

Larry,
When I do my compressions tests, I do exactly as you described.
When I did it at 378 hours, I recorded the first gauge reading and then the last
with the following results:
Cyl first / last
1 120 / 176
2 120 / 176
3 125 / 180
4 120 / 176
As you can see, the readings are consistent and seem reasonable.
So the compression looks good, I have no oil leaks, the engine does not smoke,
I get about the same amount of soot that you described but I still use an excessive
amount of oil??
I think I may try disconnecting that breather hose and run it into a small clear
container to see if the engine is blowing out any oil there.
Regards,
Bill

Hi Bill,
If I recall you run your Stratus at a much higher RPM than me (and Larry),
have you ever checked your oil consumption at a lower RPM (say closer to
4,200). Just curious if it goes up as your RPM increases???

I often wondered what that PVC valve did which is on the equivilant hose
from my valve cover. I bet
it keeps the oil droplets in while allowing the vaporous oily air out.
Hope you'r able to nail it there.

The pcv is there to maintain a constant flow of crankcase ventilation
under various manifold pressures. IOW, at idle (high vacuum), if you
didn't have one in the hose it would be a huge extra source of air into
the manifold. A bad one could give you some extra oil consumption, but I
think it would show up as high idle or high manifold pressure.
