Desperate<BR><BR></FONT></DIV>Arch,<BR>How loose were yours? I just took
the motor off the mount and checked them. I was able to snug them
up. They weren't falling out loose but they weren't tight/tight
either. The engine is on a FocusII. You know how the cheek cowls
are like on a French CAP aerobatic plane? I have the rear of those
opened up. I get residue coming out of that on the exhaust side and the
inside of the cowl on that side is wet too. The firewall is wet but
again only on that side. It would seem the stuff is coming out too high
up to be the injector or exhaust flange but so far all my guesses have been
wrong. I'm still batting 1,000.<BR>JLK<BR><BR><BR>

style="FONT-SIZE: 10pt; FONT-FAMILY: Tahoma">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 <BR>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 <BR>the flange that screws in to the
head. I have retightened the header flange. I have checked
the valve cover gasket. I have checked <BR>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. <BR>Any
thoughts?<BR>Thanks!<BR>JLK<BR> </SPAN></FONT></P></DIV></BLOCKQUOTE></BLOCKQUOTE></BODY></HTML>
