    Well, it could simply be caused by fuel with too low an octane rating, especially in hot weather. To test, wait till fuel level is quite low and add a half a tank or so of premium gasoline.
    If the knocking ceases, then it was knocking (aka detonation) due to fuel with insufficient octane rating.

    As far as I know ALL 91+ Escorts aside from the S/R require regular octane fuel, not premium.

    Yes, but my LX knocks in hot weather (like today), possibly due to deposits in the combustion chamber, or extra poor local fuel, etc.

    65K for a dropped valve seat might be a record here!
    We have a thread for that here:

    Well if you manage to not drop a valve seat, you get to do the head gasket anyway as the head bolt on the front left seems to either break or come loose. It happened to me and several other people here (denisond3 more than once) and on Youtube. It's always in the same place too! I have no idea if these head bolts need to be retorqued after installation or of it's a questionable design or casting that causes the initial problem, but it seems to cause a coolant leak at the head gasket and usually the oil and coolant don't mix. You can often drive for years with the problem.

    And let me provide my favorite opinion - that to rebuild that engine, the pistons need to come out of the cylinders, as piston damage following a valve seat insert drop is almost 100% likely. The cylinders may look perfect, but piston damage will kill the engine before long.
    If you are gong to have a Ford dealer do the work, I suppose I would opt for the used engine.
    Sorry to say I dont know anyplace to get rebuilt engines at good prices. In that arena I suspect you get what you pay for; although I might want to have an independent shop do the actual engine replace. And while the engine is out, get a clutch if its a 5-speed, or think about betting a rebuilt trans if its the automatic.

    I would say the matter of the front driver's side head bolt giving trouble is a weak point, except I have experience with flathead ford V8's and the Lycoming V8's in Cords - all of which were much worse designs.

    Could be, whenever I have a light throttle misfire or ping, I blame EGR or more specifically a dirty DPFE. I'm only right like 10% of the time though.
