OK, now I remember (I get my Healey engines mixed-up sometimes). I
replaced the tach drive cable and it was a PITA; I think it's a good
candidate for the leak as it seems to be coming from that area. I'm
gonna pull the carbs and manifolds and install your PCV kit after I
get the grill back in the BJ8 (just installed a DWM steering shaft).<br>
<br>
Thanks,<br>

<p dir="ltr">No, on the BN2 the tach drive is a skew gearbox taken
from the top of the oil pump shaft. Very conveniently pasitioned
under the exhaust manifold. Bit of a pain to remove because a
couple of the tappet cover screws are in the way. The tach drive
is on the distributor of the 6 cylinder engines, much more
conveniently located. </p>

<div> Ah, yeah, now I remember having to route the OP line
across the scuttle. But, the tach drive is off the
distributor, on the R/H side, no? I replaced the seal when
we rebuilt the engine.<br>
<br>
Tappet cover, IIRC, is on the L/H side; that was my first
guess since the oil isn't contaminated (until it hits the
pavement). I didn't learn until after the rebuild that one
of the tappet cover screws has to be shorter, lest one of
the tappets hit it; always wondered if I did that right or
not. <br>

<div dir="auto">The oil pressure take off is on the right
side of the engine Bob. My guess would be the tachometer
drive, the seal on the shaft hardens and cracks (
probably only about 70 years old, they don't make them
to last) or the tappet cover. I have found that the
tappet cover screws need to be gently retightened af a
few hours of operation. On the 100S they were all lock
wired which tells you something!!

Just noticed, after a short local drive my BN2 was
peeing oil out the <br>
driver (L/H) side of the engine. I won't get to a
diagnosis and fix for <br>
a couple weeks; just wondering if anybody has a guess.
My first thought <br>
was the OP gauge fitting came loose or the line broke,
but the gauge was <br>
indicating fine as was the temp gauge.<br>
<br>
Any guesses?<br>
