Port Plugs ( lack of other name )
 

In Question 8ba.Rebuild.

How many plugs ( oil port ) are there to be removed & replaced & there location.

I know Some in crank--- How many?

I Know behind timming gear --- How many?

And where else ? How many in each location?:confused:


REMEMBER I'M STILL A NEW "B" So don't laugh :D

Just done a 8BA. One plug behind the timing gear none in the rear. 4 in the crank,one on each throw.

I always thought all Flathead blocks had a galley plug in the rear located somewhere around the cover for rear cam/idler/oil pump gears.

The early 8ba's did have an oil plug in the back of the engine, right above the camshaft gear cover plate, also they did not have a fuel pump rod bushing... picture below shows the plug ...

Vergil, you right, that's a real early 8BA from a 48 pickup. I've only seen a couple of them. That rear plug was there so they could drill a small pee hole in to the main oil line to feed the fuel pump push rod witch as you say does not have a bushing. Also those engines had head studs and not bolts. Walt

Then apparently the only 8ba type block that I own is also an early version that came out of a '48 pickup because it does have a rear oil galley plug as shown on Vergil's picture.

Walt when I got the engine it did have studs in it, didn't have cylinder heads but a very clean engine inside. It had been on propane but had been stripped of everything. Another thing to mention is the oil hole for the fuel pump push rod is larger then the ones in the bushings. It is large enough to lower the oil pressure if it is not blocked off unlike the bushings.

Bill, when I saw the title of your thread I thought you were an old sailor referring to the left side spark plugs. :) I am one and when I started on this forum I always used port and starboard instead of left and right but soon concluded not many would know what I was talking about so changed to the popular vernacular instead. :cool:

Yea, Ford was experimenting with the 8BA in the 48 pickup. They learned a few things that first year. Walt

Ford was experimenting with the 8BA in the 48 pickup.

At the same time, Ford Canada was also experimenting; They were equipping trucks with a C69A engine. These babies have the early style bell housing, no freeze plugs in pan rails, 8BA style valve assemblies with valve rotators, hardened valve seat inserts on the exhaust only, shell big end bearings of same thickness as the floaters, and the best feature of all is the super thick cylinder wall thickness! Definitely the block of choice for larger displacement engines.
