[NSRCA-discussion] Desperate

[Archie Stafford]

John,

 

Check the backplate bolts.  I had similar symptoms and it was raw fuel
coming out of the backplate.  The motor still runs fine because it doesn't
depend on pressure for fuel delivery.  Check all 4 of the bolts on the
backplate,

Jason,
I'll try to track that down.  It seems that it's confined to the exhaust
side.  Very clear residue.  Exhaust...?  Raw fuel..?
Man I just don't know...

What about the o-rings around the valves

I have a bad fuel/exhaust leak on my YS 1.60.  It started just before my NMP
header split but continued after replacing with 
a Hatori header and 821 muffler.  I'm getting pretty desperate trying to
find it.  I have replaced all the fuel lines.  I have snugged up 
the flange that screws in to the head.  I have retightened the header
flange.  I have checked the valve cover gasket.  I have checked 
the head bolts but it still leaks.  I consider the leak bad enough that if I
don't get it fixed by tomorrow I will have to miss my second contest in a
row because of it.  It really soaks the inside of the engine compartment on
the left (exhause) side.  Bad enough that when I run my finger down the
firewall it is wet with oil.  The engine mount beams on the bottom sides are
almost dripping.  
Any thoughts?
Thanks!
JLK
