Viking 130 Oil Consumption - Zenith Aircraft Builders and Flyers2024-03-28T16:05:15Zhttps://zenith.aero/forum/topics/viking-130-oil-consumption?commentId=2606393%3AComment%3A844117&x=1&feed=yes&xn_auth=noThis is a very informative an…tag:zenith.aero,2022-12-03:2606393:Comment:8844142022-12-03T16:17:03.753Zcharlie rosenzweighttps://zenith.aero/profile/charlierosenzweig
<p>This is a very informative and helpful discussion. I do not have a viking engine; I do have 140 hours flying an R18 Honda engine that does not typically use any oil. (I did find it low 3/4 of a quart once). I have my engine venting both the crank case and the valve cover into a single catch can. I do have a turbo but I only use boost on take off. Sometimes my 16oz catch can will get full in 3 hours of flight, sometimes it takes 6+ hours of flight. I am trying to narrow down…</p>
<p>This is a very informative and helpful discussion. I do not have a viking engine; I do have 140 hours flying an R18 Honda engine that does not typically use any oil. (I did find it low 3/4 of a quart once). I have my engine venting both the crank case and the valve cover into a single catch can. I do have a turbo but I only use boost on take off. Sometimes my 16oz catch can will get full in 3 hours of flight, sometimes it takes 6+ hours of flight. I am trying to narrow down conditions that cause the accumulation to be higher than other times. I highly suspect it is a combination of high rpm, high MAP, and/or high altitude flying (over 8K, over 25" map and over 4500rpm) that are the most likely circumstances that will cause the catch can to fill more rapidly that other. I am also considering separating the crank case and the valve cover in to separate catch cans to see which one is venting the most oil. </p>
<p></p>
<p>So when it comes down to looking at oil consumption and or high catch can accumulations, The type of flying is a significant factor on how this varies between engines. I.E. how much of the flying is at high RPM? If you have a catch can, is it venting the valve cover only or the crank case vent or both? What altitude are you normally flying, and how hard are you pushing it when you fly? </p>

<p>FWIW I would suggest someone start a new thread on that bolt/mount interference. It is arguably a Servicde Bulletin level topic. Kudos who who found that. f</p>

<p>One thing that Alissa can't know is how was the car/engine treated before they got it, was it taken care of? or was it abused and used like a street racer. </p>

<p>Haven't flown it for a little over a month now as life and other things get in the way.</p>
<p></p>
<p>Currently the engine has ~120hrs on it in the plane. Since these are used engines directly from Viking, I'm not sure how much use the engine had on it when I got it. No significant change in oil consumption has been seen over the course of the 120hrs I've been using it. </p>

<p> Seems like the rings did not seat properly. Did Orlando have a long taxi time prior to first flight ie. 3to 4 hours? Did he vary throttle settings. How long did he run the break-in oil, did he put a load on the engine?</p>

<p>We have over 1000 engines out there - no it is not a common thing. We have had three people report this past two years (Orlando, Samuel and another) we haven't pinpointed the exact issue. One has been solved with the use of break in oil without issue - the two others not as much - which both seem to be low wings - so not sure if that is also coincidence. Both at different density altitudes and both have good compression. </p>
