We're going to try and get our 64 XKE 3.8 OTS running after sitting for a number of years. Car hasn't been on the road since about 1999, and it still ran up until about two years ago. Up until around 2002 it would run fine, then slowly over the next couple years it would start but die right away if you took your foot off the gas pedal, it also started making an ugly noise from the top of the engine like the lifters weren't getting enough lubrication even though the oil pressure was normal on the gauge. The last time we tried to start it was probably two summers ago. Obviously I think the problem was with bad fuel and the entire fuel system now has probably been gummed up. We're going to start cleaning that out at the fuel filter, replace the filter, replace the fuel lines that lead to the carbs, take the carbs apart and clean them, drain the fuel tank and replace with fresh gas. Anything else I'm missing? Also, for a car that has been sitting for roughly the last seven or eight years, what else should we be doing in preparation to get it running again? I've read on ferrarichat.com that a lot of people suggest putting a little marvel mystery oil down each cylinder to help with lubrication and alleviate any rust or corrosion. Thanks for any more tips and suggestions that can be offered. Hopefully we can get in running without having to turn it over to professional help.

The increasingly rough running and upper engine noise in an unused engine
are very typical of sticking valves. A compression check would likely show
low compression on some cylinders. I would remove the valve cover and squirt
some type of penetrating oil on each valve stem. Also squirt a little into
each spark plug hole. Fill the crankcase and new filter with fresh oil with
a dose of valve/lifter solvent. Turn the engine over with the plugs out to
distribute the oil. Another compression check would let you know if the
situation has improved.
After cleaning the fuel system (it should not be necessary to replace the
lines) the car should start with a lot of blue smoke out the exhaust. Do not
rev the motor any more than necessary to keep it running or you may cause
damage due to a stuck open valve hitting a piston.. After a bit of running,
it should steady out on all cylinders. You can squirt some light oil into
the intake while running to help lubricate the valve stems. You may
experience some spark plug fouling during this time. If so, just clean them
as necessary until you get it firing good on all cylinders. Avoid the urge
to rev it real fast to "clear it out". Free working valves, clean spark
plugs, and a good fuel supply will do the job.
