I replaced a cam while the engine was still in the car... I don't recommend
it.
It took the better part of a month of a couple hours here and there... I did
relpace all the tappets (it was when TRF had that run of bad tappets). I
used BFE's sleeved Ford tappets and their Babe Erson autox cam. I tried to
get the bulk of the metal shavings from the old cam out, taking special care
to flush and blow out the oil passages. I also used a magnetic sump plug.
Still over the first year as I used it as a dailiy driver, I was sure every
strange sound was my motor "cashing in its chips"...
I got over it. It ran just fine for the next few years... Joe Boruch can
take up the story from there.

That's not a leak... My car's just marking its territory...
