Hi Guys,
I took the TR6 south to Oxford, OH for the 6-PACK Trials last week,
probably less 600 miles total. The Trials were great. The Six had a few
issues.
The first was a low RPM miss that caused her to chug some when
accelerating. Usually in 3rd or 4th with OD engaged but not always. She
would chug
some regardless of speed but usually below 2500 rpm's. Once above that she
seemed happier with only a few chugs. Not enough of a problem to leave me
on the side of the road but very annoying.
So I pulled the Bosch Platinum WR7dp plugs : #1 thru 4 look reddish brown,
#5 is brown & #6 is bright white. I must be sucking in some air back
there, Huh? From the manifold gasket? I hate to just start ripping into that
w/o the wisdom of the List but the bright white is an indicater of a lean
condition in that cylinder, correct? What else could it be? The Six also
got very hot once when I let her idle for 5 minutes which would confirm a
lean condition.
I have had this problem before with the Six and also the TR250. Seems
like they both want to blow up manifold gaskets. What am I doing wrong? I
have tried the method of putting two gaskets on back to back. I forget which
way they go it's been so long. I only have one on now.
Any Tips are appreciated,
Darrell
