Ford FE 390 intake Manifold Oil Baffle
mwatterson
I have a 1970 Ford County Sedan with an FE 390 2V. There is a baffle
underneath the intake manifold which is attached by what appears to be
rivets. I can tell there is quite a bit of gunk in there and I want
to clean it. Are there any tips to getting the baffle off?
Thanks for any help.

it is not a big thing if it is not there.
i have removed it from all my FE intakes, and the aftermarket 4 barrel
intakes don't even come with it.

Jim Warman
used (this is the valve on one exhaust manifold that closes when cold -
sending exhaust gasses through a passage under the carburettor). The baffle
is meant to act as an "insulating" zone to keep oil from splashing against
the bottom of this passage (which can get very hot) and turning to hard
carbon deposits.
These deposits can flake off due to thermo cycling and always have the
chance to wind up in places they aren't really supposed to be. "Required"?
Weeelllllllll... Cheap insurance? Yup....

Thanks for the advice. I removed the baffle and there was a large
amount of deposit underneath. I cleaned the manifold and now I need
to decide if I want to reinstall it.

Did you remove the drive screws to get the baffle off, or did you just pull
it off over the heads of them? (IIRC, they are drive screws instead of
rivets- kinda like a small nail with thread-like grooves.) Like Warman was
saying, it's cheap insurance to prevent unwanted stuff from entering your
cylinders. If it was me, I'd put it back on, even if it meant drilling new
holes.

SC Tom,
I was able to remove the screws. I hit them with a chisel in a North,
South, East, West pattern until they were loose enough to pry up. The
pan in intact, but one of the screws is questionable for reuse now.
I do plan on putting it back on. After thinking about it, I want to
keep it as original as designed as I can. If Ford put it there, I can
only assume there was a reason.
Now, I need to find out where I can get more of these screws. I would
doubt a hardware store will have them.

Mike,
They're called type U drive screws. If your local Lowe's or Home Depot or
similar doesn't have them, they can be had on-line at McMaster.com.
Unfortunately, they come in packs of 100 to 10,000.

Tap the holes to accept a common machine screw.

I just checked McMaster, and 100 costs less than $5. I'll check
Lowe's and Home Depot first though. Thanks for all the great advice.
