Q: why does a full (8 quarts in most 4 cylinder engines, 12 quarts in most 6 cylinder engines) sump either burn or blow out oil? Why mark the dip stick to a quantity that will not remain in the engine? Is there any harm is running less oil in the sump on a routine basis? Answer: regulations ! Look at the FAA certification of piston engines - FAR 33.39 (a) "Lubrication system. The lubrication system of the engine must be designed and constructed so that it will function properly in all flight attitudes and atmospheric conditions in which the airplane is expected to operate. In wet sump engines, this requirement must be met when only one-half of the maximum lubricant supply is in the engine." It is this one-half comment that has caused most air cooled / oil cooled engine, for any manufacturer, to mark the dip stick to an excess quantity for normal use so that this amount rule will meet certification for any given certified aircraft installation. RVs have an excellently designed cooling plenum, so they tend to keep the oil and cylinder heads well within limits. Bottom line - you can operate any 320 or 360 Lycoming engine one to two quarts below the marked full limit. As long as the temperature stays below 245 * F and the pressure is steady, 6 quarts in a four cylinder engine is adequate to do the other functions - cushion, clean, protect, etc. Bill Gunn RV 4 1700 hours and counting ________________________________ Message 2 _____________________________________ Time: 06:31:26 AM PST US From: "charlie heathco" Subject: RV-List: Bulkhead Resposes autolearn=unavailable version=3.0.2 --> RV-List message posted by: "charlie heathco" Thanks for all the input, I should have thought it thru better.

RV8 wings are matched to the 804 bulkheads. If you get a set of wings then you should also get the corresponding 804 pieces - two large gold anodized cross members and four stamped ribs. On my 8, and I believe on all 8s, spars have a serial number which is also engraved on the 804 pieces, that's because they are factory matched drilled to each other. If you get wings without the matching 804 you might not be able to bolt the wings onto your airframe.

I have one piece flexible brake lines from the fuse to the brake calipers. A split nylon tubing covers the woven SS brake line to prevent abrasion of the gear leg and the line. The Question: I'm considering wraps of duct tape (or perhaps aluminum foil tape) around the gear leg and brake line to hold the line in place and also prevent abrasion of the epoxy paint on the gear legs by the fiberglas fairing. Is there a down side to using tape as described? Will the adhesive eventually lift the paint? Has anybody done something similar and how is it working?

Spruce finally referred me to the manufacturer of the eyeballs they sell; scoop follows. First, eyeballs for your eyeballs: http://www.aircraftspruce.com/catalog/appages/eyeballfw.php - the TTP series takes a 1.115" hole, which, I'm told, you can knock into the firewall using a 0.75" electrical conduit punch - the SE961-B and -S series both take a 1.125" center hole and come with drill templates for the [steel] mounting bolts - the aluminum eyeballs (TTP and SE961-B) can be reamed to allow larger cables. The SE961-S cannot be reamed over 0.260" Now, unless I'm 'way off today, I measure my Van's quadrant cable diameters at 0.343". I haven't seen anyone talking about having to ream the holes in their eyeballs for these cables, but it appears that many would have had to do so. Since the SE961-S series can't be reamed above 0.260", it would appear that we can't use the SE961-S steel eyeballs with these cables. So we're left with aluminum eyeballs, TTP and SE961-B. Question: did you buy .260" and ream to .343" (or something darned close) or just buy .375", and if the latter is that nice 'n tight?

What happens is that the higher oil level means the oil is that much closer to the crankshaft and rods, which means the reciprocating parts are that much more likely to come into contact with the oil in the pan during any uncoordinated turns, climbs, or unusual attitude maneuvers. When that happens, the oil splashes around, and some is turned into droplets and goes out the breather. By the way, I notice that I get far less oil on the belly if I keep the greasy side down. My Oshkosh trip this year was Atlanta to Minneapolis to Oshkosh to Chicago to Ann Arbor and back to Atlanta. With my wife along, I was under a strict edict to fly smooth, and as level as possible. I don't have the hours handy, but I'm guessing 12-14 or so for the total trip. I didn't add any oil and the belly was relatively clean when I got home. In the same number of hours of local flying, I'd probably do 25 rolls, a number of wing overs, some lazy 8's, and several other positive G maneuvers. Over that span, I'd need to add at least a quart of oil and the airplane's belly would be a mess... Kyle Boatright ________________________________ Message 42 ____________________________________ Time: 06:59:58 PM PST US From: "Jim Cimino" Subject: Re: RV-List: Oil Separator Received-SPF: none --> RV-List message posted by: "Jim Cimino" The rods and crankshaft are pressure fed in a Lycoming Engine and the crankshaft is in the middle of the engine. If you drop the sump, there is no direct access from there to the rods or crankshaft, so I don't understand how keeping the sump full adds to the possibility of the rods coming in contact with the oil? I know that can happen in a car engine, but I don't see that having any bearing on an aircraft engine. I think what causes most oil loss is just simple blow-by. These engine get a lot of oil to the tops of the cylinders and some is going to get past the guides and seals and into the combustion chamber, the more oil you put up there, the more gets by. By flipping a plane around, you may increase it. Lycoming also states that it is safe to fly an IO-360 on as little as two quarts, but the additional oil helps provide cooling.

Wow, wasn't squeezing g that thing together fun. It turned out pretty good with the top section nearest the counterbalance rib and the bottom section are very good with the riveted edge very tight. The center section is not quite as tight. There are about three places where I could not get a good bend on the edge and after riveting, there is a slight gap between the two skins. The gap is very slight in all three places but wanting to be a perfectionist, I thought I would get some thoughts from the group. Is there a problem if the two skins are not perfectly tight at the edges, should I drill the section out and try and tighten them up, or should I let it go and deal with it when I paint? Y the way, the roll is very equal and symmetrical these small gaps seem to be the only problem. Thanks for the input.

While the HSI in my Lowrance Airmap 1000 is just a fancy GPS display, it looks like an HSI and behaves a lot like one. It will even mimic an OBS and let you select a VOR "radial" or a bearing off a waypoint. I haven't had any need for the HSI display (don't shoot approaches in IMC), but it is kinda cool to play with.

I believe that if you put all 8 quarts (or whatever is 'full' for your engine) in, the level will rise above the level of the sump into the crank cavity where it's whipped a little and goes out the crankcase vent. I also think that when the level gets down to 6 qts, the oil level is down in the sump. It would be easy to check by comparing the level of the 8 qt mark on the dipstick to the level of the dipstick tube. The next time I have the cowl off, I'll check. Y'all can do the same and report back. > I think what causes most oil loss is just simple blow-by. > I think you're right! > These engine get a lot of oil to the tops >of the cylinders and some is going to get past the guides and seals and into >the combustion chamber, the more oil you put up there, the more gets by. > I don't think this is true. There is some oil pumped to the rocker area through the pushrods ..... and that oil really aids in cooling .... especially the exhaust valve. Keep an eye on CHTs for #3, as it's typically the hottest .... and has the lowest amount of oil flow due to it being at the end of the oil gallery. > By flipping a plane around, you may increase it. > Nah. Almost all the oil goes out the breather or your inverted oil system if you have one. On a tight engine, (read good cylinders and rings) the amount burned is negligible compared to what you'll dump overboard doing akro ..... unless you're really good and only pull + Gs. > Lycoming also states that it is safe to fly an IO-360 on as little as two quarts, but the additional oil helps provide cooling. > True. However, if you fill the oil to the 'full' mark (8 qts), you'll lose the first two rapidly out the breather. Bill Gunn has already covered WHY it says fill to 8 qts!!!

However as a rule it is best to not leave a a lot of stuff for later. The pile of unfinished odds and ends can get to be a bit annoying during the painting seasions when you start finding all that stuff you meant to do earlier. I had to drive across town today to machine dimple some screw holes so that the priming for final paint could continue.

The fuse structure is quie different than the RV 6 series. Maybe another RV 8 builder will chime in on the subject?.

I remember posting a question back in March I think it was abouit trying to bring my 6a down on Jeff county Ga at idle from 10 mi out at 5000'. I ended up overshooting in spite of slips and stuff. I remember quite a few responses re trying something simular. Just wondered if anyone had tried a long gluide successfully since then??

"rocket-list" , "rv10-list" --> RV-List message posted by: "JOHN STARN" The Lyc IO-540 J4A5 in HRII N561FS has the internal oil system that sprays oil on the bottom sides of the pistons. This "spray" would increase air borne oil droplets who could then find their way out the vent system. Have been told that this spray system is used on Turbo'ed optioned Lyc. etc. to increase cooling on the higher HP engines. The J4A5 in 561FS is only rated at 250 HP. Not sure IF or what 320/360's use this system but I would assume this type of system would also be on certain 4 cylinder Lyco. too. I do know anything over about 9 1/2 qts. in 561FS gets pumped overboard. Check the archives IF your interested IMNSHO in what I've posted on oil separators. (not favorable).

If in real doubt, take it to your local EAA tech advisor. One of the adages we use in my work is, the greatest enemy of good is better. Regards, Michael Wynn RV-8, Empennage San Ramon, California
