Blown 2009 600 E TEC

My brother's 2009 600 E TEC, with only 1100 miles, seized this week. No compression in one cylinder. Didn't have any prior warning, always ran great. Now he's worried that after spending quite a bit for the rebuild it won't be reliable. Hate to see him sell it. Does anybody have any history on this motor, especially following a rebuild. A reputable Ski Doo dealer is doing the work.

The Ski Doo dealer that I spoke with about this motor says; they come into the shop all the time blown up.

I haven't personally had experience with one. Too new and toooooooo lean.

"2-stroke DI way to go" NO WAY. All the new 2 strokes, poo and doo especially are running wayyy too lean. There's no way to make these last forever and run so lean on gas and oil.

I think they're just too new. They don't seem to have any troubles with the outboards with similar technology.

I think if I owned one of these sleds....I would be dumping some oil right in the gas tank to keep the sled a bit richer....and maybe give them a bit longer life.

Maybe something wrong doing it, but seems to me you could do that and improve your odds of the same thing happening....??

Can they change the programming to richen them? Sled was getting nearly 20 mpg which seems to indicate running lean. Didn't have any Hi Temp light prior to failure though.
Biggest concern is whether the cause will be repaired along with the rebuild. If it is due to a factory setting will Ski Doo back it at all? Went out of warranty in November...

Any word from the dealer on what was the “cause” of the failure? I would want that question answered prior to rebuild…have seen a fair # of 09’ 600 E-tecs with over 7000 miles on them with no troubles but there are always exceptions.

I agree with Marty P 5900 miles on mine no problems, ask the dealer what caused the problem.

I've heard of very few engine issues with these. How have the 800's been doing?

I have also heard good things about the 600 etec, however the 800 Ptek has had issues with the crank bearing going bad, my brother in law is on his second one and seems to be doing better his was a 05 and now he's running the 08 without any motor problems. Just a bad chain case, bad hand warmers and a bad drive shaft all covered under warranty. lol

My buddies 600 Etec went down the same way but his was still under warranty. When the etec goes down with no warning lights it is not a fuel/lean issue it is a crank seal/ leak on the bottom end which will cause any motor to go bad. The dealer told my friend they were told about this occurrence and it will not show up on a dummy light because it comes from the bottom end.

I would encourage your friend to call BRP because I believe from what I understand this is due to a bad crank seal. And there should be no reason other than a bad seal that it fails in 1100 miles.

I have a 2010 etec with 2500 miles and it runs great!

Putting oil in your gas actually creates a LEAN condition. Your thining out the fuel by doing it and it WONT prevent a burndown. You however will have well oiled crank and rings with a nice hole in the top of the piston. diluting gasoline with more oil does not equal prevent burndowns created by a lean condition. Might prevent a seizure (maybe) But if you have a air leak or bad fuel to air mixture issue it wont help.

uh, than why do all the manufacturers and dealers recommend adding oil to the fuel during break in period? True, the oil does not change the air/fuel mixture, but the additional oil makes up for at least some of the dryness and heat associated with the lean fuel mixture, sometimes preventing, and certainly minimizing the damage of a burndown.
Adding oil does not "dilute" the fuel and create a lean condition, either from the fuel/oil perspective, or the air/fuel perspective. Fuel injection settings and carburation manage that. In the case of modern fuel injection, knock sensors, if installed, richen the amount of fuel relative to air, to correct a lean condition, but to my knowledge, no change occurs in the oil injection volume, but i could be wrong on that point. might want to run that one past the local mechanic or engineer...
Folks, If you are concerned at all about an air leak or lean condition, especially out on the trail, add some oil and burp that throttle for extra oil injection!!.

You won't blow it up from putting in oil. If it runs hotter, the extra lubrication will make up for it.

This is completely false!

Adding more oil DOES make it run leaner. Oil does not evaporate and take heat with it when it enters the cylinder. Gas on the other hand evaporates and takes the heat out of the cylinder through the unburned fuel. That is why they say leaner is hotter. Adding more oil reduces the amount of gas through the injection or carb openings. The reason you don't see burn downs happening from adding to much oil is the engine just will not run well and foul the plug before the burn down. Bottom line is more oil will not prevent a burn down from a lean condition.

Again, false. Reread your post. How can you think it even comes close to making sense??
