jury Posted July 27, 2006 Report Share Posted July 27, 2006 i changed the domes in my noss head and i guess i didnt get the o-rings all set in right, it started running on one cylinder and radiator fluid came out of the over flow, i took that side apart and there was fluid in the pipe, and so it was in the cylinder too, i rode it for a while (not knowing that had happened) before i noticed the prob. anyone think that could of hurt or done some damage to the bearings in the crank or piston??? thanks Quote Link to comment Share on other sites More sharing options...
dajogejr Posted July 27, 2006 Report Share Posted July 27, 2006 Oh boy... Your best bet is to take the top end off, stick a syringe with a tube down past the crank into the cases, and suck whatever you can out. I just went through this. Crank rusted a little (bearings were fine) and it popped a crank seal. Next time with that head, use a thin bit of high temp RTV sealant on each of the rings. It helps seal, as well as helps keep them in place when putting it all together... If you've got fluid in the pipe and cylinder, I'd bet my money it worked it's way down into the crankcase as well. Your crank bearings and pistons are probably fine. It takes more time to remove the engine, split the cases and replace crank seals than it does to do a top end, though... Your best bet is take the top end off and get whatever fluid is in there out....better safe than sorry. Quote Link to comment Share on other sites More sharing options...
jury Posted July 27, 2006 Author Report Share Posted July 27, 2006 alright well i took the topend apart and looked down under the crank and theres no fluid down there ( i took it apart 3 days ago) so its been sitting open, and the temp has been 100+ for the last week so i think anything in there evaporated, should i be good to go with new o-rings and a little high temp gasket maker around them?? thanks Quote Link to comment Share on other sites More sharing options...
dajogejr Posted July 27, 2006 Report Share Posted July 27, 2006 Evaporate? more than unlikely. At least stick a rag down there and fish around. Blow some compressed air in there...just to be sure. for 20 bucks, get new ORings, and use just a hair of hi temp RTV on them to hold 'em and seal 'em. The coolant hose fitting in the back of the head where it attached leaked on mine out of the box, and it was tight. I took it off...little RTV, and good to go.
