Hello folks,

Checking the oil level over the past couple of weekends (check it religiously) and i've noticed that there is the tiniest of oil leaks coming from what looks like the timing chain sporcket bolt hole. (the hex bolt thing that is slap bang in the front of the cylinder head)

It seriously is like a dribble.

Wiped it away and a week later, it's back.

Any ideas as to what could be causing it? Is there a tiny seal / oil ring in there that could have moved? Is it a big job to replace, or is it simply get that bolt out and replace the seal?

Thanks

 

Yes - there's an O ring in the back of that which may need changing but you really need to read up on the how and why as if you remove that bolt too far when changing the seal you can drop the entire timing assembly down into the guts of the block

From memory ( you need to search again) you wind the bolt out just far enough to get at the O ring but there is a specific torque that must be adhered to when you tighten the bolt up.

 

Piece of cake to do just follow this link https://www.s2ki.com/s2000/topic/832...g-weeping-oil/

 

Jesus, there isn't ever anythign with this car that doesn't have consequences is there - unscrew too far and you loose a sprocket, don't screw back in tight enough and you get crank walk!!

 

Ok the Honda manual states 49NM to torque this down to. Do I go tighter, knowing Honda?

 

If you want to deform the new washer & cause another leak then yes.

Honda TQ settings are usually pretty tight. It's just that nasty harmonic around the front that makes it whine & shakes the plugs & filter loose.

 

Fixed this yesterday with Ray's help. As soon as we got the ring off, it crumbled in our hands. Definitely a part to replace every so often.
