hey guys.
did a rebuild on my bike. when putting it all back together, i noticed a dent/chip in the metal of the main cylinder block where the head gasket goes(around the cam chain tunnel area).
in the photo is where the chip/dent is exactly. its not the exact photo of my cylinder on the bike but where the red circle is in the photo is exactly where the dent is and where it ends. the rest of the metal surface behind it is fine.
it's definitely deep enough to get a finger nail in it and deep enough to be able to seal up with putty or something. the cylinder head with the head gasket has been torqued down to spec but the head gasket hasn't quite bonded into the dent fully.
im just wondering, should i bother to even get this fixed or not?(i can take the cylinder back apart if need be).
and is there any way dust could get in, perhaps from underneath the head gasket/where the chip is(where the gasket doesn't quite seal with the uneven/dented surface)?
sorry if its a silly question but just wanting to make sure. i want no further issues with the bike.
Bike is a KTM EXC 2004

the head gasket and cylinder head is already on and torqued down.
did you mean the put a light bead of silicone/gasket sealer around the cylinder head gasket area to help seal it? because that's what i was thinking of doing but wasn't too sure if i should or not.
its only at the front/outside of the cylinder. behind the divot is still all flat and smooth. there's about half a width of metal behind it.
its deep enough to feel with a finger nail and deep enough to be able to "patch" the divot with silicone or JB Weld.
why couldn't i put silicone around the head gasket area where the divot is? if that'll keep dust out and will stop it from leaking out? cos i don't particularly want to take it all back apart if i can avoid it.

Silicone it on the outside and see if it leaks. That area shouldn't see any significant crankcase pressure like others have said. The spot either leaks or it doesn't. You probably only ride the thing a couple of hours at a time at most. You aren't flying it to the moon either. Seriously, it's a 2004 and it probably leaks worse somewhere else already.
Ride it, add oil to it if you need to, and get over it.
its kinda funny how some people are quick to dismiss a topic/issue/question by just focusing on the year or age of the bike therefore labelling the issues as totally irrelevant and like nothing matters just because of the year/age of the bike.....but to some others, such as myself, despite the year of the bike or how old the bike is, we care about our bikes, its our pride and joy and we want to be able to ride with no further issues(seeing as ive had plenty of them with the bike thus far).
some people actually care about their bikes and pride and joys a lot. just because some people don't like to make sure and check up on things, doesn't mean others don't. ive spent a lot on it, therefore am trying to avoid any major issues for a while, thus why i wanted to ask and make sure.
the old mindset of ride it, put oil in it might be how some people go about it, but to some others, we like to make sure everything is all good and fine.
i was more concerned about dust being able to get in or not......not so much oil leaks.
don't be so rude and dismissive next time. some actual friendly help and advice would be more appreciated next time.
there are no oil leaks currently from it. was just concerned about dust possible getting in.
how would i seal it without taking it back apart if i end up needing to though...by using the sealant around the edge?
stop worrying and go rip the shit out of that old thumper
this isn't from the bike exactly....but this is exactly what the chip/divot looks like and exactly how deep and how big it is.
the divot goes from the very outside edge of the cylinder where the red dot is in the original photo from post #1... to about half way(width wise/toward the cam chain tunnel area).
behind it(where the divot ends and where there is about half a width of flat even surface), the head gasket seals perfectly and the surface is flat.
thanks
Post a reply to: dent on side of cylinder block(water pump side)??
