Hi DG.........one quart in approx 40 miles..not a drop on the ground...coolant is clean. not overheating or running wierd...cant see any smoke even on a hard acceleration...will check airbox when back at the house asap.. thank you.. rings..? valve stem seals etc ??? Theresa ps might be putting new jugs on the Bonanza in my picture .down to 20 % on one cyl.... damn turbos!!!

I brought this over so everyone could see what has been checked.

A quart every 40 miles should be smoking like a freight train, yet we've had several people indicate pretty much the same thing you're saying: no smoke with huge oil consumption. Almost makes me wonder if oil companies are putting stuff in to prevent smoke...?

There are ways to determine what the cause is from when it smokes...but that is obviously dependent on actual smoke. Best way to determine the health of the rings is a leakdown test. I hate to say it, but unless you can find a leak somewhere, it may be time to hit a dealer and let people with the proper tools (in theory anyway) make the call.

I would say you have a bad camshaft. My rincon(same engine) wouldn’t smoke but used oil. Top speed was affected too. My first cam went a 3,000 miles.

Hi please tell me what was wrong with the cam. Bad lobes. ? Bad seal? Adjusted the valves and had full lift thanks

The cam was worn down. It happened to me 3 times. Every 3,000 miles. Honda did give me one free cam and they replaced the oil pump but blamed it on not letting it warm up. One service manager said there were bad cams out there (Honda would never admit that) in 2007 and 2008 but that doesn’t explain two more bad cams. I put new rings in it at 10,000 miles.

HI Thanks for that.....my big red has lots of power...no indication of worn lobes ...as i said the lift looked good when I turned it over for the adjustment..it runs up to the rev limiter in seconds..topping out at about 42...bad cams hmmm ...ive used reground cams ..with 100 % success..on other engines VW Porsche etc...maybe bad parkerizing...just saying, thank you very much for the input...you guys are great.... dealer or American Honda didnt help at all ...saying they have no problems except stator issues....Theresa

That's great that you have the tools and know how to use them. Probably gives you a leg up on the local dealer

The one sore sport with this engine is that one occasionally eats a cam. Goes all the way back to it's Rincon debut, and is still happening in 700 pioneers. It's too much to call it "common", but it does happen. Maybe the worst thing is that there seems to be no definitive answer as to why. Low power is the sign, so sounds like you're ok.

Hi. DG. Thanks. Can’t believe I’m having trouble with one cylinder. Imagine that good thing I’m not dealing with a v12 jag engine!!!‍♀️

1 other thing if you havent checked your airbox. my dads was doing this same thing a while back ended up being pvc line going into airbox. soaking air filter so it was burning it but because it was going through the filter and basically atomized instead of being dumped by a valve. no smoke.

OK just got what your saying....so basically im spewing oil out the breather and its reburning it?..so i possibly have worn oil rings..T

 

[onesparkplug]

Hi ok so im thinking worn oil rings ..spewing blowby into air filter?...hence no smoke?....T

 

[Alan_Vander]

not exactly oil rings. i cant remember if its an actual valve like a car or not. my dad fixed his and told me what it was doing
he is snorkeled so he does have a higher vaccuum on his airbox than stock bikes. ill see if i can find the part online but it was stuck wide open so basically just pulling oil straight to the air filter

Cool im headed there now 4 hour drive if you find out the part please post it so when im there ill look at it thanks again D. D. T

 

[Alan_Vander]

i cant find it in the diagrams online just follow the hose coming out your breather if your filter covered in oil. if its not then just wipe this from your list. lol.
