  1. Yes I know all about the lycoming additive vs camguard as that topic has been beat to death in Mooneyspace. I live in Las Vegas where we see 110F days and on the runways even hotter. Ive been using 20w-50 in the winter, as temps warmed up in the spring 80w+ and with summer temps over 100F I switched to 100w+. The problem I am seeing is the thicker oil is causing very high oil temps. I am in the green but on the up end of that. Talking with Philips at OSH they recommend I go back to the 20w-50 Victory even with these summer temps that I am routinely in to help get more oil through the cooler. I have gone through all my baffling, sealed everything and even went through with a pick and made sure all radiator fins are getting the max air flow. Been having to fly with cowl flaps open to keeps the temps at bay. Is 20w-50 safe for these high OATs and lowering the oil temps as well?
  2. Also for anyone needing some help or work done to these older systems, Kevin @ 539-292-0474 started working for Brittain back 1978 and has been an incredible help. Was able to get my remote gyro rebuilt and working like a charm. Reach out if you need anything.
  3. Hey all, I know the topic has been beat to death over engine monitors but I have decided to go with a JPI 900 so I can get rid of the engine instruments. Been getting prices for installation and its all over the place. Branching out to look nationwide for the best JPI installer. Been getting 40-60hrs+ quotes from local shops but I don't want to pay them to learn the install but find the guys that know this the best. Any recommendations for shops would be appreciated! I do have an AP buddy that would oversee an install myself but sounds like I maybe biting over more than I can chew.
  4. So I would like to update this for anyone that finds themselves in a similar situation, 66 model Mooneys had a separate "remote" gyro installed on the pilots side underneath the panel which can also be accessed through the outside of the plane from a panel located between the main top engine cover and the windscreen. In 1967 Mooney installed the gyro into the turn coordinator. If you have the trim knob on the yolk, you have a remote gyro. Porter Strait Instrument has a past employee of Britain that built these levelers working there with great knowledge and will still rebuild some of these units. The simple way of testing the system is to apply suction via mouth to each of the red and green lines, you will see the yolk move to one side with red and back the other way with green. I found that red was just fine, green couldn't hold vacuum. Both red and green have a T in the line and that is located in the baggage area behind the interior paneling. (the panel farthest from you looking into the baggage area). This T has line going into the tail servos (which can be access through the tail inspection panel on the pilots side) and the other is routed directly to the ailerons. After disconnecting the T you can vacuum check both the tail and ailerons vacuum for leaks. I very quickly found a leak on the green side of the line in the tail servos rubber boot hidden on the back side. I've been told people have had success using bike tube repairs. I'm going to have the boot replaced (hopefully). Hope this helps anyone out there with similar issues. After many many hours of research, calling around and talking with some guys I feel like I know this system almost like the back of my hand now. To anyone searching around and looking at the maintenance manual(highly recommend on in the download section), be very specific with what year of the diagram you are looking at because they are all lumped together. Also replacing the o-rings inside the push button cutoff valve in the yoke will make a great difference and that simply just pops right out by hand. For my original post the black cracked line goes into a vacuum filter located behind the pilot side paneling.
  5. Here is the file for 65-67, found it to be very helpful information. Looks pretty different than what I am running underneath. 65-67 PC.pdf
  6. Some great info there, looking more and more into it I found that the line only going into the filter. I finally found this schematic and looks like 65, 66 and 67 were all a bit different in the design, going to starting down any vacuum leaks. 66 Schematic.pdf
  7. I just discovered that while I was underneath, going to start following the wires, not a clue
  8. Just looking for the information on where everything goes, not a ton of information. Just trying to track down the system and see what is going on as I cannot get it to work at all. I bought the plane and the owner passed and sold in an estate sale. A local mechanic tore it down and pretty much rebuilt every thing, new motor/prop, avionics and rebuilt the PC wing level and that is why all my vacuum lines are pretty new. That diagram above really helps! Was that from Brittan?
  9. I have read about all the forums, I just can fully figure out which part I am looking at and where it goes. I appreciate the contact for Alan Fox as well, I will reach out.
  10. Recently purchase a 66 M20C and am looking and tracking down the issue to why its not working. I have opened up the servo compartments and found the rubber boots to be in good shape (pictured). But I looked underneath the panel to see the vacuum lines conditions and found this line extremely cracked line and it had fallen off. It does look like all the lines have been updated in the last few years. Obviously this will be replaced but trying to understand the system more. Looked at every diagram and trying to understand where this line even goes!
