AndrewPatry Posted January 21 Report Posted January 21 Is anyone familiar with DLC coated lifters and where to source them. I read Airworx is FAA approved. Looking for quick off the shelf. TSIO-550-G2 Acclaim Sent from my iPhone using Tapatalk

AndrewPatry Posted January 21 Author Report Posted January 21 Given the condition of that lifter, I'd like to see the cam.Cam passed the pick test. But that lobe is not the prettiest, Supposedly the DLC coated lifter will polish the lobe . Sent from my iPhone using Tapatalk

I'm sure someone will be along shortly to correct me, but I have not seen DLC lifters used on Continentals. Usually it's Lycomings that eat lifters and cams, while Continentals eat valves. If the cam looks okay, I would probably replace all the lifters and move on. They are pretty easy to check at each annual. 2
N201MKTurbo Posted January 21 Report Posted January 21 There are Facebook posts that says these guys can DLC coat Continental lifters. There is nothing on their website that mentions it. Maybe they can only do it on their rebuilds. https://airworxaviation.com 1
jetdriven Posted January 24 Report Posted January 24 Call them, but on their Facebook page and via email they said they are FAA authorized to coat L C and F lifters. Byron, We have approval to do all of the Lycoming, Continental and Franklin lifter bodies. Sincerely, Chris Collum COO Airworx LLC. 251-809-2959 1

I would have had to buy at AirPower and ship to Airworx. Told me 4 weeks turn around. Sent from my iPhone using Tapatalk
AndrewPatry Posted January 24 Author Report Posted January 24 4 weeks in aircraft parts time is an hour and a half in real time.No kidding. Couple years ago I waited 6 months for cylinders. Supply chain has improved but nowhere as efficient as construction or automotive. Waiting for piston pins Wednesday and the new lifters Thursday. I feel for the shop that it’s ripped apart in.

kortopates Posted January 25 Report Posted January 25 Its nice to know the DLC treatment is available for Continental lifters, but what you found should only happen after sitting for a very expended time period if not periods. Since they are easily replaceable in TCM engines, unlike Lycoming lifters, I am not sure I would I spend anything extra for the coating - its not the problem it is in Lycoming engines; especially when flown regularly. 1

C&B in South Dakota has an approved carbide surface but I couldn’t find a good phone number for them. The plane really never sat. Its last teardown was 200 hours before I bought it. I have flown it another 803 hours in 6.5 years, always in a hangar at home. Before my ownership it sat outside at Palo Alto. The problem was that lifter was ground and an ECI rebuilt. Anyone considering a top overhaul should ship a new set to Airworx before it’s taken apart. Learned a life lesson. Sent from my iPhone using Tapatalk
kortopates Posted January 25 Report Posted January 25 ….Before my ownership it sat outside at Palo Alto. The problem was that lifter was ground and an ECI…Those are two solid strikes against them all before your ownership, parked on the ramp right by SF Bay, and using ground lifters over new. Superior Lifters were less than $100 back then and still under $150 now.Corrosion is the number one killer of our engines, but it’s really uncommon to see a TCM lifter get that bad; especially with how easily they are to check.

I've heard of insurance companies paying for an engine teardown after a prop strike, but never for worn or corroded parts. When the bank owned it though I could see them making it airworthy with the cheapest parts possible during an annual or pre-buy. 1
