I have a Titan 370 in my RV-8 and I'm still burning 1 qt of oil for 5 flight hours, with 225 hours on my engine. This has been an on going issue for several years, obviously. Talking with Titan, Bobby Looper and all, I used Phillips X/C 20W-50 for break in oil and continuing on with it, as per Bobby. According to Aeroshell, that was the improper oil for break in and it appears to be too late now. Talking with Continental at Oshkosh, I was told to borescope the cylinders and send them the pics which I did today, haven't sent the pics yet. There was oil sitting in two cylinders. Several people have suggested it needs a light hone then re-brake in the engine. Talked to my engine mech at the airport and he said carbide nickel cylinders cannot be honed. So, I am here to find out from the vast knowledge of information here what course of action do I now take. Live with it? What about the long term potential damage? Can't hone, so the other options is new cylinders, extremely expensive. Ideas please?
