ryoder Posted December 18, 2014 Author Report Posted December 18, 2014 Yes its never been majored and the details on a top overhaul at 1100 hours are nonexistant but referenced in the engine logbook two. Original engine logbook mia. One new cylinder in the 80s also. I agree that a major is the better option if I have a bad cylinder. This one might just foul the bottom plug. Id like to scope it though.
Marauder Posted December 18, 2014 Report Posted December 18, 2014 I dont have an engine analyzer. The cylinder is at 2500 snew. Are you interested in one? I'm pulling my 830 and installing a 900. 1
Hank Posted December 19, 2014 Report Posted December 19, 2014 Sounds interesting, Alan, if it can replace my factory gages. My panel is somewhat full . . .
drapo Posted December 19, 2014 Report Posted December 19, 2014 So what would your cost be if you had a C? I'd say, around $1500 with labor!
rbridges Posted December 19, 2014 Report Posted December 19, 2014 So what would your cost be if you had a C? it's considerably less. you can also go with ECI brand. I believe the IO360 cylinders are only made by Lycoming IIRC.
MB65E Posted December 19, 2014 Report Posted December 19, 2014 If it's a first run cylinder I would have it repaired/overhauled vs buying or exchanging...
jetdriven Posted December 19, 2014 Report Posted December 19, 2014 That's one of the time where you're happy to own a C... Just learned that I'll have to change a cylinder on my E, with labor, it's going to cost me $3000 just in time for X-Mas! That seems a bit high from my experience. Swapping a cylinder on a Mooney is around 6-8 hour job plus parts. You can get a new cylinder, piston, and ring kit for 1200$. so around 2K laid in. http://www.aircraft-specialties.com/o-320-o-360-replacement-cylinders/?sort=alphadesc inspect the cam very carefully before opening the cylinder kit. If there is any unusual wear, rust, pitting, or spalling on the cam or the lifters, send the cylinder back. You need an engine overhaul. Dont be like the guy I talked to a couple weeks ago. They pulled a cylinder off to inspect the cam on a prebuy, it "didnt have too much rust on it" so they closed it up and bought it. It was a MSC, too, BTW.
drapo Posted December 19, 2014 Report Posted December 19, 2014 That's about the estimate I came up with for my E, 6 hours labour and a new IO360 A1A cylinder assembly, which is the Angle valve Wide deck Lycoming at around $2300... Pretty close to $3000! If I had a C, the cylinder assembly would cost around $1000 and 6 hours labor for about $1500!

They pulled a cylinder off to inspect the cam on a prebuy, it "didnt have too much rust on it" so they closed it up and bought it. It was a MSC, too, BTW. I found out about corrosion in the crankcase of this 600 SMOH engine only after buying the plane. I did know from the pre-buy that one cylinder had an exhaust leak from a bad valve guide- the other 3 were good on borescope, and no metal was in the filter or screen. To recondition and re-install that 1 cylinder cost me $1200 total. Unfortunately pulling it off did reveal a few spots of corrosion in the crankcase and a single small pit on one cam lobe. But otherwise the lobes and lifters themselves were all in good shape- no spalling whatsoever. Wish I had known before buying, but a tear-down seemed premature? Doubt it will make TBO, but it didn't sound unsafe to fly. Per the MSC mechanic, the lifespan is unpredictable, but it should give plenty of warning with metal in the filter when the time comes.
carusoam Posted December 22, 2014 Report Posted December 22, 2014 Dev, Anymore detail on corrosion in the crank case? It's a machined aluminum casting, not known to have this challenge. This would be the first I have heard of corrosion in this location. We have plenty of aluminum corrosion issues in other places. Best regards, -a-
Wakeup Posted December 22, 2014 Report Posted December 22, 2014 Question for the guys that opened up there engine and noticed corrosion. Have subsequent oil analysis showed what you already know?? Thanks. Troy

Best regards, -a- Question for the guys that opened up there engine and noticed corrosion. Have subsequent oil analysis showed what you already know?? Thanks. Troy Sorry - did not mean the crank case itself- superficial rust was seen on a couple of exposed areas on connecting rods. When the issue came up, I discussed with a couple of other mechanics besides the pre-buy A&P, and no one seemed to think it merited a tear down. The engine was underused for the first few years after the last overhaul and then was flown a lot more, so the corrosion has likely been there a while. It's getting an oil change this week after breaking in the reconditioned cylinder, which will make metal so no point in worrying right now. I'll subsequently watch the oil analysis, screen, and filter for a few 12 hr interval oil changes to make sure things are acting stable.
