My38 Posted May 30, 2013 Report Posted May 30, 2013 (edited) hey, ive got a 4K with a 5 speed, and there is a small leak from where the trans bolts to the engine. not sure what it could be. could someone please help me. is there some sort of seal that could need replacing? thank you :) Edited May 30, 2013 by My38 Quote
ke70dave Posted May 30, 2013 Report Posted May 30, 2013 Either the engine rear main seal, or the gearbox input shaft seal. Probably the engine rear main though. Quote
My38 Posted May 30, 2013 Author Report Posted May 30, 2013 alright, is that easy to replace? guessing you would have to take the gear box out? Quote
My38 Posted May 30, 2013 Author Report Posted May 30, 2013 is it a big problem? or would I be able to leave it as it is? Quote
ke70dave Posted May 30, 2013 Report Posted May 30, 2013 yeah gotta take the gearbox out, flywheel and clutch off. The rear main seal sits around the crankshaft and seals against crank case. i dunno what engine this is, but the 4k will look pretty simliar http://forums.pelicanparts.com/uploads18/Rear+Main+seal+depth+just+below+bevel+marked+in+red+Photo+credit+Tyro+Rennlist1299935335.jpg The thing in the middle with all the bolt holes is the crank shaft (bolt holes are flywheel bolt holes). and the rubber thing around the edge is the seal you replace. howeever, be VERY carecful you do not scratch the crankshaft surface, or the block surface, or you will never get it to seal. http://www.rollaclub.com/board/topic/26273-how-to-remove-front-and-rear-main-seals-on-4k/ if you don't have an engine manual, get one! they are really good for stuff like this.

My38 Posted May 30, 2013 Author Report Posted May 30, 2013 thank a lot :) ill take the gear box out when I have time and sus it out :) it should be alight to drive with it like it is though?? Quote
ke70dave Posted May 30, 2013 Report Posted May 30, 2013 Well the worst thing is you are losing oil and making a mess of the concrete. I wouldn't put it in the urgent category, but the sooner the better. Quote
My38 Posted June 3, 2013 Author Report Posted June 3, 2013 alright :) thanks for that :) cheers for the help Quote
kickn5k Posted June 3, 2013 Report Posted June 3, 2013 I've also seen two K50's with the input shaft seal plate that has a crack from top to bottom. Both were behind stock 4K's. Quote
corollaart Posted June 4, 2013 Report Posted June 4, 2013 I would work out if its gearbox oil or engine oil ,no use making work for you self. rob Quote
My38 Posted June 4, 2013 Author Report Posted June 4, 2013 what would the difference be?? and how would i figure that out? Quote
kickn5k Posted June 4, 2013 Report Posted June 4, 2013 Used gear oil stinks. But honestly you have way more of a chance it being a rear main crank seal than a gearbox plate crack. Didn't mean to alarm you just saying I'd seen it before. Quote
My38 Posted June 4, 2013 Author Report Posted June 4, 2013 Aha that's alright! I reckon it could be the engine oil! It's doesnt stink at all! Quote
ke70dave Posted June 4, 2013 Report Posted June 4, 2013 You will know if its gear oil, its an aweful smell. Sounds like rear main then. Quote
My38 Posted June 4, 2013 Author Report Posted June 4, 2013 Yeh I'm guessing that would be the case! Do you know where I would be able to buy a new one? Quote
