Sonoran Dave Posted February 26, 2020 Author Share Posted February 26, 2020 Green chile flapper! My wide open crankcase breather wasn't up to the task of handling crankcase pressures correctly, and I spewed a bit of oil out the breather, dipstick tube and prop hub. The amount of oil loss has lessened considerably as the engine accumulates hours(It's up to an 1 1/2 hours now). I was told by another pilot who has been flying 1/2 VW's for many years, that a crankcase flapper valve would help a lot with oil control. I guess the pressure gets vented, then the valve closes, allowing a bit of vacuum to develop inside the case. This vacuum is supposed to help keep the oil inside the case. It is essentially a PCV valve...just like in all modern vehicles. Now I could have just gone down to an auto parts store and sourced the biggest PCV they had, but this project could not have gotten as far as it has...if I solved every problem with a credit card. So made my own PCV out of some junk drawer parts and can of green chile. 5 Quote Link to comment Share on other sites More sharing options...

Guest Posted February 26, 2020 Share Posted February 26, 2020 I hate to be Bob Bummer regarding the Pcv, but my inner pessimist warns me of risks to the engine should the pcv grenade and the engine eat some of it. It has no basis on your design, but is based on recent threads on Suby forums( with new Subiroos ) having defective pcv, followed by subsequent engine failure. Have you considered a screen between the pcv and engine, as well as an AOS downstream of the pcv? Quote Link to comment Share on other sites More sharing options...

I think I have room to cram something in, and I have an idea how I would implement it. I am waiting to see the results of this experiment first. I dont want to add any unnecessary weight. 4 hours ago, BMc said: Cool Dave! Can't wait to see what you do with a can of enchilada sauce !

Guest Posted March 2, 2020 Share Posted March 2, 2020 (edited) I think with another 159 pounds to go Sonora will make it, easy, under the 254 max weight limit. There is always the "cloud hook" (103.23C) exemption to augment slightly overweight airframes. Edited March 2, 2020 by Guest Quote Link to comment Share on other sites More sharing options...

There is always the "cloud hook" (103.23C) exemption to augment slightly overweight airframes. Last time I weighed the fuselage, it was 121 lbs. That is basically complete except for the wings, tail and engine. Wings come in at 35-40 lbs each, 20 for the tail and 100~ish for the engine. I expect it will weigh close to 325 by the time it's done. 70 lbs over FAR 103 definition. The majority of ultralights out there are overweight, but in today's snitch society...some nosey MF'r will call the FAA and complain. It has happened to a few other builders. The only option seems to be the legal route, or pull everything about the project off the interweb...and just fly it. Rarely I have I heard of anyone actually being weighed the FAA. I have heard of someone having to show pics of their build on a set of scales(good time to insert cloud hook eh?). 2 Quote Link to comment Share on other sites More sharing options...
Guest Posted March 2, 2020 Share Posted March 2, 2020 I would guess the C.G. being situated properly is a greater concern than being a mightly portly. Does FAA poke there nose into that? I assume it is centered about the cockpit? What do female pilots call that area? Quote Link to comment Share on other sites More sharing options...

The CoG range of this design is approx 25-30% of the wing chord. Meaning ~30% back from the front of the airfoil.

Maybe the FAA figures that since they have no control over pilot weight, regulating airframe weight is moot. Quote Link to comment Share on other sites More sharing options...

I think it is more of a manpower thing. So they lay low and wait... for some moron to poke his head above the crowd. I bet all kinds of fun "regulation" will swoop in at that point. I downloaded the application for my N number a few days ago and will be dropping it in the post directly. I don't want issues with the fuzz. 1 Quote Link to comment Share on other sites More sharing options...
Sonoran Dave Posted March 23, 2020 Author Share Posted March 23, 2020 It finally stopped raining long enough to allow me to resume work on the engine. I had planned on ditching the oil filter after break-in was finished, but lately I have been wanting to make the oil filter a permanent fixture in the oil system. The size of the filter (Fram HP-1) kept me from doing this before. It was too darn big...and too heavy. I did some searching and came up with an alternative filter that fits the same filter bases as the HP-1. Wix # 51393 is also much smaller! The smaller footprint allowed me to tuck it behind the number one cylinder. You can see in the pics how I adapted my existing brackets. I ran new 1/2" oil lines to the filter head. This has worked well so far. Moving the oil filter required relocating my ignition coil, which was easily switched to other side of the case. I also added a vacuum port to each intake manifold. This will come in handy for carb tuning and when installed in the aircraft, a tap for a manifold pressure gauge. I also received my new TinyTach and got it installed. I don't plan on running the engine again until the weather warms up some, but hopefully it will work fine when I do. 2 Quote Link to comment Share on other sites More sharing options...
Guest Posted March 23, 2020 Share Posted March 23, 2020 Unless you buy a high end Fram(ultra or whatever they call it) I believe the Wix is better, overall, bang for your buck/quality. I think "bob is the oil guy"'s forum is pretty keen on anything Wix makes. As for carb equalizing, you could always disconnect one sparkplug(then the other) and tune each carb to a similar RPM Quote Link to comment Share on other sites More sharing options...
Sonoran Dave Posted March 23, 2020 Author Share Posted March 23, 2020 Wix filters are great. I have used them for years. I have a couple of old vacuum gauges which makes that whole process much easier. Quote Link to comment Share on other sites More sharing options...

Old Tom Posted March 27, 2020 Share Posted March 27, 2020 Dave, you could have gotten my 1968 Square Back I sold a couple of weeks ago. Would have given you a real deal bro.

Old Tom I have wanted a Beetle since I watched Herbie the love bug as a very young kid. I grew up and forgot about them, as we don't see too many of them in Alaska. Now that I live somewhere warmer and I have been re-exposed via the airplane engine and Patches the tube buggy...I really wanted one again. I have a plan for it, and it will be a solid little car capable of highway or off road travel. The interior on this one is in fantastic shape. I think it's been re-done before. The rust is minimal and the engine runs. It will not idle though. The carb needs to pulled apart and rebuilt. Next week, I'm going to do a compression check on all 4 cylinders and based on that, pull the engine for rebuild or just fix it. 2 Quote Link to comment Share on other sites More sharing options...
