Turbo apex problems, need help

[03rmking]

So here's the background...

2006 Apex, MCXpress turbo 4200 miles. For the past two months the sled has been using oil. Probably put in 4 quarts over 20 rides. I thought the seals in the turbo were bad because it was blowing oil out a loose fitting on the wastegate side of my turbosmart boost controller and also blowing oil out the top two small hoses that come off the top of the intercooler. But it hasn't been consistantly using oil. Sometimes I'll ride several days and not need to add any. Some other times it uses a quart in a single day seems like. And I haven't rolled it either.

So last ride out, sled is running fine for first few hours of the day and then starts bogging when in a wide open pull. Clears out sometimes, other times not. Throughout the day the bogging gets worse. Gets to the point where it develops a low end bog that is has trouble clearing out. Now it's puffing black smoke out the exhaust, the side of the 5 gal can on the back was black after about 30 miles. Get back to the truck and it's worse than ever. Now it won't idle. Have to give it gas to keep it running. Shut it off, start it half hour later to load it up and it's running on two cylinders and flashing a code. Don't remeber which code but it was either 33,34,35, or 36 which are all...

"Fault Ignition"
"Open circuit detected in the primary lead of the ignition coil"
"Cut the injection of cylinder in the same group with the cylinder that the error is detected."


So I pull the turbo apart thinking it's dumping oil. But it's bone dry on the intake and exhaust sides. Pull the intercooler and there is no oil in it. Only traces of oil are in the two small hoses off the top of the intercooler. I capped these off with a zip tie so I think the oil has been there since I first found it blowing out oil there. No traces of oil anywhere else.

So any ideas what could it be? Does it sound like a oil change and fresh set of plugs would be the answer? Still don't get why it's been using oil and why there was oil blowing out on the loose boost controller fitting and the boost leak on the two hoses off the intercooler. How'd oil get in there.

Any ideas?

The rings might be ****y

I would look at all the plugs and do a compresion test and start eliminating some possible problems. Really sounds to me like bad rings though

I would definetly do a compression test first off. My sled has also been using oil. Not a whole lot but enough that I need to add half a quart after every 4 rides or so. The motor was built with relatively loose tolerances for pouring on the big boost. Not sure weather to be concerned or not. Keep us updated with your results. Good Luck

start with the simple and cheap things first,what oil did you put in?hypoid,semi or full syn.,what are your spark plugs gapped at,remember you can't gap them at .028-.032 and run 15-18 lbs. boost,regap to .022-.024,what does your filter look like?maybe I'm thinking like a diesel tech,but boost is boost,what controller are you using maybe too much heat.Might be time for a tune up.I will shut up now,anyone else?over brother

leave it be it just wants to be a 2 stroke burn oil and run like garbage... lol

i would get an artic cat and turbo it that would fix the whole thing

Hey now..... we have a little hickup here, no sense in going to that extreme.

Your sled rips! But I would like to see you get anywhere near 5000 miles on it! I think I'll go with an impulse nytro for my next sled. After all it's was the winning sled at the BDSO

Great suggestions, will snap pics of the plugs and do a compression test asap.

i got 1500miles and still going i wonder who will win next year what about that artic cat 1300 i hear its fast

Your sled is a runner for sure! Looked like a ton of fun to pilot. Ran into one of your buddies at a gas station just south of the border. He was sure wondering how the orange cat did!

this seems to be the norm for low comp pistons je are better than the wisecos but the still go through some oil it has got to do with the rings.outlaw motorsport is getting je to cut there pistons to fit the stock rings & it seems to have stop the problem.

couple other things to check are your return line from the turbo & you should pull the cover off the oil return pump & make sure everything is good in there some of the pumps have had probs over the years & will cause oil loss.as for the missing prob check you 2 boxs up front they get water in the plugs & will creat all sorts of crazy probs.

How much compression should it have with a head shim?

Maybe the little orange kitty should go back to the kitty cat forum where he belongs....

It was fast for sure but there is a lot of chest pounding going on for not being the winner. No matter how fast you are or think you are there is always someone that will show up and put you in your place

i like to think of it as the tiger of the cats maybe you should bring your boosted hevy weight out for a race

 

[up-high]

Maybe you should start your own thread and let 03 get some info !

Wow thats some funny sh$it--- All I have to say is while you guys were getting frost bite we had powder. This is kinda like Nascar he who has the most money wins.

The compression test is a good thing but I would do a cylinder leakage test that will tell you if you have ring problem-intake valve problem or exhaust valve proble it is way more accurate than a comp test it would be Ideal if you could pull the plugs and post some pics I know that is easier said than done but none the less you need to get them out and the comment about gap is very important if you gap is off by much(to large) under high boost the cylinder pressure will blow out the spark and will cause several issues. If you do the compression test make sure that you check it 1st stroke second stroke and third untill you get the max and then compare each 4 readings against all 4 cylinders.
