Hi, I have a -97 s1 with turbo, my problem is that the engine is burning up my engineoil, i thought that the problem was that i didnīt get rid off the oil from the turbo but thatīs not the problem. So can it be that both head gaskets has blown at the same time. Sorry for my bad english Iīm from Sweden Ronny | ||

sounds like it is time for a top end rebuild. Do a leak down test to see if the rings are bad If the leak down test passes more than likely all you will have to replace is your valve seals. But do yo know the last time the top end was refreshed? It may be a good idea to just throw some new rings, maybe cylinders or bore the cylinders out and throw in some oversize pistons and do a valve job... | ||

Thankīs, the bike worked perfect in october when i put it in for the winter, the problem came on the first ride this year so i take off the turbo and the headers and both exhausts look the same black and (carbon). I will do a leak down test tomorrow. | ||
| Firemanjim |
What turbo? And is it a blow through? After those questions are answered I will go from there. | ||
| Ronny |
Good morning Yes itīs a blow through and i thought that the problem was that the lubrication oil to the turbo didnīt evacuate fast enough so i drilled a 14mm hole in the cam cover and drained the oil that way. before i had the oil drained in the plug between the cylinder base, there i build an extra breathing hose so i get rid of the pressure in the crankcase. Now i will do my leakdown test, see you tomorrow, thanks for your answers:-)  | ||

Nice looking set-up. If it was running well before I'd be looking at what you changed last. How are you feeding fuel? What is AFR under boost? Is it a ball bearing turbo? Won't be head gaskets, maybe rings so leakdown will tell that. Did you do some full throttle runs and go lean, burn a piston? How do the plugs look and what plug are you running? Reread your posts, sounds like sitting messed something up--stuck needle and seat flooding too much fuel ?? Let us know what you find. And give specs/details on your turbo set-up. | ||

That does look really nice. Out of curiosity, what kind of exhaust are you running? And I wouldn't worry about your English. It's better than a lot of people who speak English as their primary language. | ||

I run turbos on my cars. It could be a seal letting go inside the turbo, sending oil directly from the turbo center section to the exhaust. It's hard to explain...but turbo oil smells different than engine oil being burned in the combustion chamber. It's more crispy-smelling, if that makes any sense, it doesn't smell like grandpa's old beater car burning oil at all. Compare the exhaust ports at the engine to the exhaust outlet on the turbo and see if one is greasier than the other, or if they match. If they match, it's in the engine; if the turbo dump is slicker, it's the turbo seals. How's the turbo shaft play? (pull the filter, grab the turbine shaft and give 'er a wiggle - it should barely move). | ||

Has done a leakdown test, no leak. But i think i have solved the problem. Now i`m taking out oil with a T-connetion on the oil pressure conntact and dumps it back in the crankcase, and that oil shouldn`t be in the engine at all because the oilpump don`t evacuate the crankcase quick enough. So i thinking of build a catchtank for the turbo oil and pump it direct to the oiltank with a electrical pump. The turbo wasn`t on when i put it in for the winter. I will be back   | ||

Ron, you could plumb into scavenge side of oil pump to suck the oil out. | ||
| Ronny |
Hi Firejam What does scavenge mean? Is it the suction side from the oiltank to the pump | ||
| Ronny |
Sorry Firemanjim, missread your name | ||

Ronny, it sounds like the seals in the turbo are leaking. It is a very common problem. You can put some seal conditioner w/ fresh oil and run it. If it works than you know your turbo need a rebuild. What are you using for a fuel pressure regulator??? Just wondering. BILL | ||
| Ronny |
Hi Bill There is no oil in the compressor house on the turbo so I don`t think that`s the problem, and the turbo is new. Iīm using a walbro pump and a liear Malpassi regulator. I will test Jims idea before I buy an expensive oilpump. Ronny | ||
| Ronny |
To Mudshuvel The exhaust is made by me with a supertrapp megafone  | ||
| Ronny |
I got an idea don`t know if it is a good or bad one here it come. If I take out oil from the drainplug in the crankcase and pump the oil up to the tank. What do you people think of this idea? Ronny | ||
| Limitedx1 |
I dont believe there is a drain plug for engine oil in the case.....the drain is off the oil tank. my opinion is a high volume oil pump and tap the feed line to the turbo, then a return line to the oil tank | ||
| Hugie03flhr |
Ronny, Zippers makes a pump with two scavaging intakes. You can use one for the turbo. I may have misunderstood but oil can push into the exhaust side of the turbo. That is the side that fails first because of heat. Good Luck that is some nice fabrication work!!! PS do you have a web site for the companies you got the fuel parts from? | ||
| Ratbuell |
What kind of turbo? If it's a garrett, I've got a guy that I've used for YEARS on my turbododge stuff, he does awesome work. Even got Carroll Shelby's attention in 2001 - he was looking at my car, an 89 Shelby CSX-VNT, and pulled one of his engineers over. Carroll: "We didn't put a turbo THAT big in those, did we?" Bob: "uh...definitely not. But, it's still a VNT..." I ended up giving Carroll one of Chris' cards. Last I heard, Carroll was running the same 60 trim VNT that I have, on his 16v 86 Omni GLHS  But yes, it does sound like your turbo oil seals could be on the way out. | ||

you have a turboed S1 and you're running the stock brakes????? you're crazy!!!!!!!!! | ||
| Firemanjim |
Another thing to take into consideration is what sort of bearing is in the turbo--Buells have low oil pressure compared to cars/other bikes as they are ball bearing cranks. I have an aftermarket oil pump and it has several extra scavenge ports--I plumbed my turbo into it. | ||
| Ronny |
Goodmorning everyone Hugie03flhr or Jim. Do you got a partnr. for this oilpump from Zippers? My sister lives in Fresno so i can get her to send me one. Italian don`t worry the bike doesn`t work yet. Jim you may have a point there with the oilpressure. I have always run suzuki before this one and they have ball bearing crank to but they may have more oilpressure. There is a harley tuner here called Tassen Racing that have a old xr1000 racebike, he drilled a hole in the crankcase and buildt a tank under the engine that he pumps the oil from after that he get 1100 rpm more out of the engine. The sping is gone it`s snowing outside  Ronny | ||
| Hugie03flhr |
zippersperfomance.com and #613-140 is the part # for the pump. | ||
| Hugie03flhr |
OPPs that number is #613-150A for the 4 stage pump. The other number is for 3 stage. | ||
| Ronny |
Thank`s Hugie I will send an email to zippers and ask for a price. I found the problem with the oil, donīt now if i want to tell you what it was because you gonna laugh at me, what a hell here it comes, I change the swing arm to a newer model in the winter and i had squeezed the scavenge hose and a breathing hose, so now i told it. Now to the fun part the, bike works almost great it is onley some small tuning before it is time fore the Dyno. Ronny | ||
| Hugie03flhr |
Ronny, what do you have for ignition? I found with a turbo, keeping the timing from advancing until 2500-2800 helps alot with drive ability and pinging in a stock compression engine. The stock ign. won't let you do that. | ||
| Ronny |
Hi Hugie I have got a email from Zippers, the pump costs 782$ so i will wait with that one. I`m still having stock ignition and it seams like it works. I still have some fuel problems to work with but I can say the engine got a lot of torque that haven`t been there before. Ronny | ||
| Ronny |
Hi I`ve solved the fuel problem yesterday and now I have to fix my clutch. The bike runs perfect no misses or dipps in lamda I hav`t got it up in the dyno yet so I don`t now the hp and tourgh. Ronny |
