Default Time for a new cylinder

Itís now time for a cylinder replacement. My purchased new IO540 in 2015 now has 857TT and 1100 Hobbs. Number 2 had a low compression reading 80/18 and after new valve guide, Iíve decided to just replace it with all new.

My question is this: Anyone have experience with a certain brand of cylinder replacement such as Superior, etc? If so where did you order from and which model?

Any advice and ideas will be appreciated and thanks in advance.

Thor

Before replacing anything Iíd want to know how a 1000 hr cylinder can have such poor compression that canít be fixed with valve work?
As to your question: I used to hold Superior in high regard, but after the crankshaft fiasco (where they wonít make good on brand new cranks) Iíd be cautious about doing any business with them.

I would worry more about getting a cylinder of any brand than what manufacturer. They are very scarce at the moment. You might want to consider a rebuild on that one if it is in fact a cylinder issue.

I had to replace a cylinder at 800 hours on a factory new engine. I had something get stuck under an exhaust valve, which overheated the valve and seat. At the time, I was able to obtain a new Lycoming cylinder locally the same day. I then sent the old cylinder out and had a new guide and valve installed and the entire cylinder overhauled. It took about 2 weeks to overhaul the cylinder. I keep this spare cylinder in case I need it in the future, it's on hand.

In today's environment, you may have a hard time getting a new cylinder. Update It appears that Airpower and Aircraft Specialties has the 05K2-1104 in stock.....

Default Cylinder Work

I recommend Sal's Aircraft Cylinders in Prosper TX 972-346-3339. They are an old-time shop and Sal and his son have many years of experience. They do good work and are pretty fast.

I just had 4 Titan x-340 cylinders overhauled by Gibson aviation. Turnaround took about 8 weeks but they look good.

Thanks Bill. I just ordered a new LYCOMING for 1800, full set. I am going to let them install my old cylinder with new valve and guide as its in good cond. and install the new one this winter as i know #2 takes the most stress anyway. I am down here in Mexico and very happy with the mech., not to mention $200.00 per day rate.

Bob, The valve is showing hot on top and the guide needed replacement. They commented that the cylinder and rings looked in excellent shape. She doesn’t burn any oil and i bought the LYCOMING new in 2015 and since have 1100 Hobbs time. I would show a picture but i doing know how to upload.

I donít know if anything is happening fast these days; my set of 4 cylinders have been at Salís for over 6 weeks with no end in sight. They are ECI Cerminil jugs though, so apparently they need extra processing and time.
