Those hoses look a little wet
There not leaking are they?

[Kopfjaeger]

im pretty sure they arent.( but ive shown my diagnostic skills and knowledge of this bike are crap). what i did last night was go over and over my tensioner , new gasket again retensioned and cleaned cleaned cleaned. went riggghhht over everything, took all the fairings and absolutly everything off to engine and frame and wheels only, used a loctite gasket goo instead of highttemp atv sealant( blue sensor safe stuff) cleaned and retapped threads loctite primer and then thread locker .( i know its going to be a pain in the arse to get out .... but  ill worry bout that later), 3 cans of degreaser on the engine and then a good ol crawl around and over the engine withtorch  lights and mirror, the ferrule in the airbox( top bolt) spun in the housing, broke it out, hole in the airbox now patched ( my neighbours are learning new words all the time.... this COULD BE why ol mate next got up to mow his lawn at 7 am today..... but i digress) its back to only having the fairing and tank off, going to put the tank on in half a cup o coffee or so and fire it up and well see..........    i even followed the destructions for the loctite and let it cure for almost 24 hrs!!!!!!!...... and as for the screaming for vengence.....chuckles got that... actually was interested ... you know the song they all went to court over? the i ummm song they reckoned caused suicide? i always thought it was " beyond the realms of death" on stained class..... but.... it s actually the song " better by you better than me"  go figure  i still reckon spinal tapp got it dead right.........

  I think i found it a pin hole in the front of the cam moulding just above the second fin. can get end of scribe about 1mm in and the engine is clean enough to see where its coming from. taint the coming from the back. all this because i originally cleaned it all over to make it pretty cos i got jealous of all the shiny bikes. bugger eh? i think its a case for contact cleaner and a bit of quick steel. although i do have some high temp epoxy resin they use for sealing electrical cables in underground equipment...... feck it coffee and a ciggy are in order. and then check for more holes.....

and listen to BLACK SABBATH ...." never say die"  nice and loud to repay the lawnmower this morning.

[Kopfjaeger]

 3 ways i can do this. all have merits. i throw the options to you wise gentlemen of fj land. 1. bit of stag gasket paste.( wont really get into engine but may flake off)  2. loctite quick steel.( may work into engine and is also grainy? in finish may still weep) 3. drill out to small set screw size tap and insert set screw with loctite.( best option cept for the operator ). what would you guys choose??  i used to be indesicive but know im not so sure.........

[Travis398]

I have had pretty good luck with JB weld (and the loctite equivalent) seem like the same stuff so the results have been good. I filled a hole 20 times bigger than that in my KX cases. Sand and clean it up pretty good so it will adhere well, do a couple coats first one really really small, second really small.........etc. as needed.

I can't see this hole your talking about from the picture? is it that black speck or the rust looking area?

[Kopfjaeger]

the rust looking area. took me 10 minutes to find it...( used up my vocabulary of swearing... so actually got to concentrate) that little speck in the middle of the rust area is the point its originating from. tank off bike running on float bowls and me under the bike with a torch. those headers get warm...( hence the red dot on my forehead.)

[Harvy]

Wow Neil, well done mate.......that is barely visible (and with my eyes it would not have been found at all!).

I would personally go with option 3, with a twist - a cap head screw with a fibre or copper washer under it.

I bet there was in inclusion in the alloy when the barrels were originally cast.

Thats a better pic... Yeah Im just a bit pleased that the paint wore off or I never would have found it !! I'd just like to say thanks again to all for helping , and i hope i provided good entertainment...( trust me I'm always laughing at myself... so its nice when others join in!!)   just gunna plug it with quick steel till I get access to the right gear, haven't got a small enough tap, and I'd like to use an inhex grubscrew. . Thank you linesman , thank you ball boys copyouslater!!!!

[Marsh White]

Wow - I wonder how the hell that happened?  You're sure they go all the way through right?  Bad casting originally?  I can't see how that could happen...I need some enlightenment.

Been following this oil leak posting for a while now.  I remember seeing a story on Pashnit.com about a 2ND gen bike loosing a large chunk of metal thru to the cylinder wall, exposing the piston.  He was still able to ride the bike to the next town to get a UHaul, pouring oil all the way.  I think I have seen other stories about frailties in the casting of these barrels.  But the FJ. being of sturdy stuff, never stranded their master over this.  

Has anyone else heard of any issues with this from other sources?

+1 on the JB Weld.  Never failed me yet.

Had a similar experience with a small inclusion in a brass freeze plug on an old V-8.  The small steel inclusion rusted all the way through and caused a cooling leak.  Almost never found that leak.
