Cheer up ! If it's any consolation, you're not alone - "been
there, done that" a couple of weeks ago !! :-( Got 4,500+ on
climb, 2,000 fpm this time - yahoo !! Everything looked great
until 2/3 way down downwind, then - poof ! clouds of smoke from
the top of the cowling, then the cockpit filled with it ....
opened the window, tried to hold it open with my elbow to get fresh air.
(Note to self - be sure to build in a good source of fresh air !)
Yet another steepish turn from base to final, lower than I like,
All temps off the end ! Power back, but decide to try to keep it
running until on the ground .... a couple of sputters ...
Got it down and off the runway, shut down & coasted most of the
way back to the hangar. .... Whew ! ....
Exactly the same - tower asking about crash crew - finally 'negative'.
Don't think inhaling all that glycol is good for the lungs !
Yep - blew the coolant hose off the top rear of the engine.
Fortunately, everything has checked out ok - compression still
good, no burned bearings, ... will try again in a few weeks.
I think the word is spreading to towers everywhere - clear space
for V8 Meeseses !!! I think they groan now when I taxi out ! ;-)
Had a long hold while they cleared other traffic before takeoff, but
temps stayed about 200 - great ! Lots of power now !!
Two days flying, 3 emergency landings - up to 1.5 hours now ...
They say "That which doesn't kill you, makes you stronger !" :-)
Sooo .... anxious listeners want to know ... was it a hole in
a piston, or just a plugged vent line ... or ????
PS
If you really want to burn off altitude, use 3 notches of
flap & push !! Get back to 2 notches before landing, though ...
VERY difficult to do a good one with 3 notches !!

Multiple engine runs on the ground including multiple max power runs. A few
adjustments to the carb and distributer. Everything looking good. At the
run-up area everything looks good. All gauges in the green. Coolant and
oil temp low but off the peg. Down the runway I nearly lose it because I
wasn't flying the airplane. I was watching engine gauges. Everything looks
good. Climb on upwind, all is well. I'm only getting 4000 RPM max which I
don't quite understand, but running smooth and all looks good. Turn to
crosswind and there is a slight drop in RPM to about 3800. Turn on downwind
and looks good. All of a sudden, power loss, rough engine, and smoke out
the right side of the cowl. I immediately tell the tower I'm landing on the
runway I just took off from but the other way. Power off, nose down,
airspeed climbing, losing runway fast. Despite not having explored the
plane's flight characteristics yet, I decide on a significant forward slip
to lose altitude, S-turning to keep as much runway left for me as possible.
I land disturbingly near the end still carrying too much speed. I pull the
stick into my lap and apply maximum braking. Somehow, I make the turn at
the end and taxi clear and shut down. I look back at the runway and there's
a huge cloud of smoke. No wonder the tower kept calling to ask if I needed
assistance as I was trying to manage an emergency landing. I ignored their
calls for a while then finally managed a "negative" on the air. I didn't
know there was that much smoke. I get out and look for fire. Just smoke.
I discover the source of the smoke. There is oil dripping out of the right
hand exhaust pipe. Dangit! What now! I open a cowl door and find the
dipstick almost all the way out. I also see signs of oil around the
breather caps on the valve covers. Excessive crankcase pressure? Really?
Why hasn't this manifested itself during ground runs? Maybe because I don't
keep the engine running at max power for very long on the ground. I figure
0.2 in the logbook for this flight. That's twice as long as the last one.
I'm getting awfully tired of emergency landings though. I bet the tower is
like, "Oh no, 744MK again. Clear some airspace for him."
