I got to work on #409 some more over the weekend and got the timing correct.
Oh what a change in the way it runs. I had not put a timing light on it and
just set it by ear and missed it a mile. It got me thinking about the fact that
these engines run so well when they are right, but they run so poorly when
anything is amiss. I was lucky and when I got my car the previous owner had
bought every manual he could get. I have spent many an hour reading. I wonder
how many people are unhappy with their Cosworth because it needs to be tuned.
But I digress..........

This car is a 75 and is black on black with a 4 speed trans. and geared 373
as near as I can tell. It was garage kept in Texas for most of the last 14
years and was purchased in Knoxville Tn. by the previous owner in the early
80's. I will send pictures an soon as I get to borrow my neighbors digital
camera for a few minutes. More soon. Jon Denton......CV #0409 Maryville Tn.

When I first bought my car, I noticed oil in the radiator. This is
reason that started my full engine rebuild.

Thanks for the advice on the timing. I had set the timing by ear and
gradually made it to 8 degrees advanced before I got the light from my next
door neighbor. It really is better now at 12. I have never seen a set back
light you mention, and I am not sure how it works. However, I think I have got
another problem. The last trip out I noticed the exhaust looked like I was
starting it up on a cold day. I saw steam for about 30 seconds after start up (
it was inside the garage and it was warm weather). I think I will be sick,
because I think the head gasket did not seal. It drives fine and I see no
significant coolant loss. The exhaust clears up and looks fine in less than a
minute. I pulled the plugs and looked carefully down the holes and #2 looks
like it could be leaking (looks moist). I changed the oil and it was clean and
free of coolant. I really dread pulling the head off again, but I will as this
is the only way to fix it. Any advice on what might cause it to not seal or how
to fix it? Is this a common problem ? I will start pulling it this weekend.
Thanks Guys..........CV #0409 Jon Denton

Do a thorough check before pulling the head gasket. Check the oil,
the radiator fluid, check both levels, and also check what color the
exhaust is coming out of the tailpipe. It could be a valve seal, did
you change these before installing the head. CV 0999 has 85k original
miles on it, and the valve seals are bad. On start up, blueish smoke
comes out for less than a minute, than the exhaust looks fine. YES, I
KNOW THIS IS NOT AN IDEAL WAY TO TREAT THE MOTOR, before people start
yelling here, but currently two other CV projects are underway for
me. Anyway, do a thorough check before pulling the head,
Later,
John J, Cowall
