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.

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. http://www.macsmachine.com/images/subaruengine/full/packing&heads.gif http://www.macsmachine.com/images/subaruengine/full/packingheadassy2.gif http://www.macsmachine.com/images/subaruengine/full/packingheadassy.gif Ron, There should be 7 nuts if you count them. You could almost count the holes in the first link picture above.

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.

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 ________________________________ Message 4 _____________________________________ Time: 02:24:42 PM PST US From: "Kelly Meiste" Subject: Re: Stratus-List: Carb Elbows --> Stratus-List message posted by: "Kelly Meiste" 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!

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 ________________________________ Message 6 _____________________________________ Time: 03:27:11 PM PST US From: "Kelly Meiste" Subject: Re: Stratus-List: re:consuming oil --> Stratus-List message posted by: "Kelly Meiste" 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 bet it keeps the oil droplets in while allowing the vaporous oily air out. Hope you'r able to nail it there.

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.
