Thanks Larry but I replaced the NMP header with a Hatori.

Are you using two copper gaskets between the head and the NMP Header?
 
Not sure if it’s the same as the 140DZ problem…I needed to run three washers or it would leak by. One on the inside of the NMP Header and two on the outside. I also had problems with the Header vibrating off.
 
I ended up at Lowes and bout a 4 foot copper pipe and a pipe cutter and made my washer. It was a bit thicker, worked perfect and hasn’t vibrated off since in about 50 flights. I keep checking after every flight...still good to go…
 
A side note, I’m not using a header brace. The one I had didn’t fit and since it still hasn’t vibrated off with the thicker washer, I didn’t worry about putting the brace on.

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
