Long range tanks on a M20K might be able to do it. 104 Gal at FL230 and 9.5 GPH with that tailwind. Even have enough for 45 min reserve. Heck of a long time to be sitting in a Mooney though. Sent from my iPhone using Tapatalk
Yes, we’ve scoped, done compressions. It’s dry inside. Compressions are good. Everything forward of the divider is clean. Through a process of elimination we’ve arrived at the Garlock seal at the vacuum pump. Also evidenced by a rotary spray pattern on the top cowling that gets distributed a bit by the intercooler flow. Hopefully this fixes it and the pump lasts a bit afterwards too. Sent from my iPhone using Tapatalk
Merlyn was already on so I can't comment on its price, but the Turboplus Intercooler was about $5400 and then 12 hours of labor for install.
As a followup, we've done a few washes, ground runs,and seal changes. Looks like the culprit is the vacuum pump garlock seal at this point.
My oil consumption was a quart every 25 hours or so much like yourself. Performance gains as advertised from the Turboplus, very happy with it. Hopeful to get to the bottom of this today or tomorrow.
6.5-7 was its happy place. We’re resealing the oil filler cap and line today and then going to do a bunch of runs checking the seals at the starter, alternator, and what not. Could be a long day. Sent from my iPhone using Tapatalk
Yeah that would be on a good 3-4 hour leg. It’s about half that or less on any other flight. And on the rare occasion it doesn’t vent it’s usually at least made a mess of the left nose gear door. Sent from my iPhone using Tapatalk
I’m quite aware of the purpose of the breather tube. Compressions are all mid to high 70’s, its a 300hr engine. The only modification was the installation of the intercooler.
I’m wondering if anyone else has had this similar situation. 1 qt of oil out the tube every flight is getting annoying. And yes the dipstick is correct. We added oil 2 qt at a time to 6 to verify that a wrong one didn’t get put on when it was overhauled 4 years ago.
Again I’ll say that the only modification was to the induction system in the form of the intercooler install. We talked to Mooney about it initially and they had nothing. Said there’s a reason they all come with separators now. Their words not mine.

Hey gang. Have an M20K 231 with the -GB, Merlyn wastegate and Turboplus Intercooler. I had the intercooler installed last year. Ever since that install my breather tube is making one heck of a mess. We’ve washed the engine down several times. Used that special flashlight to detect oil leaks. Seals are all good. Bought an Airwolf Separator to hopefully take care of this, although I’ve been told it may not actually help despite their claims. Found the install instructions on their website, seem to be much better then the generic book they sent us not mentioning actual instructions. Doesn’t look like they accounted for an intercooler STC. Anyone have pictures of this install or opinion on my breather tube pukefest in general? Mike Sent from my iPhone using Tapatalk
depends on the throw of your throttle but 2/3 of the way in is a pretty good start. Put your index finger at that point and slowly increase until your finger tip is touching the stop. Your turbo should come in about that point. As you accelerate you will need to fine tune the last portion but that should be a pretty good starting point.
Like mentioned above the merlyn will not give you overboost protection.
