I retorqued mine at 120 hours, it should have been done at 10 hours. It's
not a very difficult task. If the bolts do get too loose, the worst that can
happen is blowing the head gasket which, depending on where the failure
occurs, will cause some loss of compression in one or both cylinders and may
allow oil and/or coolant into the cylinders. It's not likely that the bolt
will come loose but retorquing at 10 hours on a new engine is a highly
recommended precaution.

Kelly,
I do remember having to re torque the heads, but it didn't register any
additional
movement at the wrench. All I got was a click on each bolt/stud. This
was after
Ram redid the valves and it had run for several hours, so the re torque
info probably came from Ram.
You won't have harmed anything unless you develop leakage between heads
and case.
Do it when you decide to adjust the valves next time.
I sent an email to Mykal on the advisability of using the in-flight
adjustable-prop last week
and he responded by email within a couple of days. Said to watch the
bearings more closely
for a while. No other anticipated problems with it on a Stratus.

I think head gaskets differ between manufacturers...Either way mine have
always moved after I replaced the heads...And believe me I've replaced
the heads more times that I have ever wanted to.

This post has me wondering????
My Stratus came with no warning to re-torque the heads after 10 hours.
So after 125 hours on my hobbs I have yet to re-torque them. Has
everyone let this go also, or has everyone but me re-torqued their
heads?
I've been trying to get a hold of Mykal for the past week with no luck,
has anyone else heard from him lately?
Thanks in advance for any advice.

There is a procedure documented in the Subaru manual
on retorquing cyl. heads. You have to untorque the
bolts a bit (one by one -- something like 1/4 of a
turn if I remember) and retorque.

Thanks for the responses to my head re-torquing question. Seems odd that in
the Stratus maintenance guide under "appendix A" they don't specify doing
this important procedure? They DO tell you to change oil at 5 hours, and
adjust the valves at 20 hours, but no words of caution on re torque the
heads???
(Still no reply from Mykal)!
I'm afraid his customer service is going down hill fast, and sadly if this
doesn't improve quickly I'm afraid we're all going to be stuck with an
engine without "factory support" because he won't be selling engines much
longer.
As a side note, my plane has been grounded for the past week (yes waiting on
Mykal) due to my plastic carb elbows becoming soft and needing replacement.
I'm now at 125 hours and my elbows lips that contact the carb flange has the
texture of hard chewing gum. So anyone out there coming up on the 100 hour
mark better start paying close attention to these as the fuel is pretty hard
(or soft?) on them.
Thanks again for the replies!

Kelly,
Just take the elbows off and throw them in the trash. The filters fit
just fine directly to the carbs on the 601 at least.
When you adjust your valves, simply retorque your head bolts BEFORE you
adjust the valves.
About the only thing Stratus has that is unique is the redrive, the
second ignition will fail and its not a hard mod to make your own....And
MUCH cheaper than his or buying the genuine (and cheesy) Subaru pick up
ignitor module in the distributor that is notoriously feeble.
Basically the redrive will die eventually but there are others we can
replace 'em with.
Bottom line, we don't need Mykal in the long run.
Frank

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

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.

Is it simply an open hose end?
Or must I do something special with the end??
Sorry if this is a stupid question but this is the first I've heard of this
method.
Thanks,
