IO-360 is being overhauled at Zephyr engines (KZP) now. it is $$$$$$$$$ that makes them fly.

I purchased a 1965 M20C which I am restoring. IO-360 is being overhauled at Zephyr engines (KZP) now. Finding a bird that is turn key will be challenging. it is $$$$$$$$$ that makes them fly.

Time will tell, I do plan on keeping it a while.

thank you I'll ask about it.

Thanks I'll look into it.

Mkruger2021, The overhaul estimate given was $30,000. The Repair will be sufficient as most engines can run well past TBO recommendations. My last bird a 1974 B19 sport was flying well past 2650 hours before I sold it. Moreover I do not wish to overspend past the potential market value of the plane should I choose to sell it in the future. Besides the engine, the airframe including tires and avionics, paint and interior all need money. One does have to set a limit.

LevelWing, thank you for the encouragement. I sure will document the progress. When its all done I can fly over to for you to see.

Carusoam, thank you for your reply. I purchased a project that was started back in 2008. The owner due to health was not able to finish. It is my intent to have this Mooney flying by November 2021. I have ruled the overhaul out. The engine is heathy and not worn out. An Inspect, Repair as Necessary (IRAN) with new cam and tappets will provide me with an airworthy engine for many years to come. The tree things that every aircraft needs is $, $$ & more $$,$$$!

Hello all, thank you for your insight and input. Here is where I stand with the plane at present. Two cylinders were removed and cancer was found on the cam and tappets, significant corrosion. The Manager of Zephyr engines (KZPH) inspected and said he estimates the engine repair cost at $12,000. That is unless the opening of the case reveals otherwise. He also paid a compliment for pulling the cylinders. The cylinders pulled are in ideal condition with no corrosion. While the engine is being repaired the airframe will be put back together. It is estimated that the restoration including repairs, reassembly, paint and new interior etc. will lighten my wallet some 60K when it’s all over and flying. This is my first restoration project. It has been an eye-opening experience thus far. I am open to more advise and input regarding the task at hand. Again, THANK YOU!

Thank you all for your input. I spoke with a Mooney A&P and he recommended pulling a cylinder if no corrosion found then top and accessories overhaul. If the worst is found an overhaul is needed. The inspections are schedule for Monday the 19th of July. I’m naming my new bird “MO MOONEY$” in honor of my late pet cat (Molasses) and soon to be light wallet.

Greeting from KZPH Florida. I purchased a 1965 M20C that is disassembled partially and my goal is to make it airworthy. The log books show the engine has not been operational since 01/13/2007. The engine has had only one overhaul since new by Triad Aviation, TSMO is 1113.37. Last annual was 01/09/2008 with compression recorded as 1)72, 2)72, 3)73, 4)74. I was told by an old-time pilot to have the engine borescope for corrosion, if ok, do a compression test, if good then oil change and fire it up. I like to know how sound this advice is. I am thinking disassembly & inspect innards for corrosion, if ok, then reassemble having the cylinders and accessories overhauled for return to service. Your thoughts please.

I see your point. I would prefer a airworthy high time engine Mooney with decent paint and interior. Instruments and avionics maybe original.

A slightly neglected bird in need of restoration or upgrade works. Maybe a very high time engine is preferable.

Thank you for your i Understood, I believe any budget bird requires $$,$$$.

Hello all I am a previous Beechcraft owner, now I seek a Mooney M20E, M20F or M20J 1970's to 80's. I am not afraid of high time engines. I prefer individual sellers. My budget is up to $60K. Thank you in advance for your help.
