From memory:
2 on each head
2 on each side of the block
a few (!) behind the flywheel (one large for water, other for camshaft from memory)
Think there's 2 or 3 at the front of the engine behind the timing cover backplate as well?

How do!
I've just bought a Ford packeged kit from Burtons which has 1 at 2" dia, 1 at 1 5/8" dia and 12 at 1 1/4"dia.
Clean the holes in the castings to remove rust, find a socket or similar that fits inside the cup side of the core plug, use some good quality gasket goo around the edge and radiused corner, tap them in until they are just flush with the casting. Make sure they go in perpendicular, aligned with the hole axis.
Regards Brian.

thanks very much,i wont be fitting the larger ones as i hopefully dont need to remove the gearbox(famouse last words) ill wait till it needs a clutch then change em
I did manage to fit the ones on the side of the engine apart from the one behind the starter today plus the 2 at the back of the cylinder heads,nice and easy to do as the body is now 10 inches above the chassis i also used the sealant as suggested so hopefully no future leaks,thanks for that top tip,now ive got a few days free over easter so ill be under the car painting the chassis ,also trying to get my mate to do the small repairs that the chassis needs as he is a welder by trade

There's no point in changing blanking plugs (as opposed to core plugs) because they don't corrode. However I'm not sure how many there are or the position of them other than the obvious one that closes the camshaft tunnel.

in my experience its usually the largest one that rots out first, well worth changing if you have the plug

In my experience, the ones at the back of the engine only start to leak just after you've fitted a new clutch....

Jim, if you need to be careful removing the cam plug at the back, what is the recommended procedure? I have a weeping, damaged one! Thanks, Geoff.

Ideally you would use a broom handle from inside (cam removed)

If you need to do it from the outside, the plug won't rotate as it abuts the rear cam bearing, so I think you'll either have to try and pull it out (self tappers) or simply seal it with JB weld or similar (which I think I would do unless the engine is out)?

First option is out of the question as my mother-in-law needs her transportation........

Engine is out of the car so it's a little easier. Is it a conventional core plug, i.e. not threaded? Thanks again.

I'm not aware of any threaded core plugs on the Essex (there are threaded plugs but they are used to seal oilway drillings - and there a few of them which rarely get removed to clean the oilways; Coupe Racing has mentioned them several times in the past). They are a (very) tight push fit.

Just to clarify , the very small plugs that have a recessed hex in them are threaded and not a push fit.
All waterways core plugs are interference (crush) fit and can be tight
I always paint the rear of all my core plugs to help prolong their life

I don't feel it's necessary to replace the cam gallery plug unless it's externally corroded and then the worst you will get is an oil leak

It looks like the cam plug has had an attempt to remove it, unsuccessfully, and it's suffering due to this. While the engine is on the floor it makes sense to replace it properly, have you ever removed one externally Coupe Racing? Cheers.
