irishfield Posted October 16, 2010 Report Posted October 16, 2010 UUGGGHHHH !!! I don't mind doing this so much when it's a paying customer.... but this is my own machine! I'd much rather be fishing on a friday afternoon, that's for sure. They don't make fuel like they use to... exhaust valve guides shot after 215 hours. Clearance is like throwing a wiener down a hallway.
vinnimon Posted October 16, 2010 Report Posted October 16, 2010 Dont feel bad Wayne! Im in the same boat! What im doing to prevent any stress is go fishing first, for relax time then go at her!Engine that is!
Roy Posted October 16, 2010 Report Posted October 16, 2010 I know you love that kinda stuff, Wayne. It's all Greek to me though.
danc Posted October 16, 2010 Report Posted October 16, 2010 I don't know Wayne. They look fine to me. I think that perhaps you were just a little bored.
spinnerbaitking Posted October 16, 2010 Report Posted October 16, 2010 Checking maps of Simcoe & packing for a Clubbie out of Barrie, hope we figure something out, but if we don't I have a great Boater & we'll have fun any way Richard
Nipfisher Posted October 16, 2010 Report Posted October 16, 2010 like throwing a wiener down a hallway. I knew a girl like that.
irishfield Posted October 16, 2010 Author Report Posted October 16, 2010 That's about how it works Raf. New valve guides and we'll "buff" them to size! lol Tomorrow I'm gonna change the oils in the Verado and Kicker, winterize the plumbing and get the boat ready for Muskie hunting!
Terry Posted October 16, 2010 Report Posted October 16, 2010 maybe you can just slap a VW motor on that thing LOL
Tybo Posted October 16, 2010 Report Posted October 16, 2010 Thats it, a couple of bolts. Thats so easy peasy. Man did I ever get into the wrong trade.
aplumma Posted October 16, 2010 Report Posted October 16, 2010 Did they start adding Ethanol to avgas??? or is it the lower sulfur?? that seems not near enough hours to burn exhaust guides. I have never seen/worked with aircraft motors but in diesel language it seems like a short time. I am sure you will get it straighted out and back together quick enough. Art
irishfield Posted October 16, 2010 Author Report Posted October 16, 2010 Art, the old WWII technology is designed to run on 80/87.. which has about 5 times less lead in it than the 100LL that we can only get now. 100LL has about 15 times the lead in it that our LEADED regular car fuel use to have. It's the extra lead that causes valve sticking and erosion. The guides don't really get burnt, they just get worn away until they get so sloppy the valve stem can coc k and break. I hate the smell of car gas in an airplane, but I'm thinking I'm going to have to go that way and use premium and lead additive to create something similar to the 80/87. Just becomes a PITA constantly checking fuel sources for ethanol before filling the jugs/aircraft fuel tank. As ethanol is an absolute no no in an aircraft and it's sealed fuel tanks.
irishfield Posted October 29, 2010 Author Report Posted October 29, 2010 (edited) Well I made the right call pulling them all off and it's the best $1200 I ever spent. It was going to be a WHOLE LOT MORE expensive if I let it go for a few more hours... as it was going to be catastrophic! Now to put "humpty" back together again, now that the cylinders/valves are all redone. Edited October 29, 2010 by irishfield
bigbuck Posted October 29, 2010 Report Posted October 29, 2010 Cracked Valves!! Ouch, that will leave a mark!!! I'd hate to imagine what would happen if it broke during flight, you'd have a real nose heavy glider.
Terry Posted October 29, 2010 Report Posted October 29, 2010 yeah real good call but you should be muskie fishing instead
fishnsled Posted October 29, 2010 Report Posted October 29, 2010 yeah real good call but you should be muskie fishing instead Agreed. It looks like a great winter project. Since it's still fall...go Nice to know that you'll be around for a while and didn't leave this repair until it was too late.
