what thickness?
on the back of my engine theres all sorts of bracketryt for water sensors, coil packs and stuff. well i don't need all the brackets so
i've done away with it. it leaves a hole on my cylinder head where the water is though. what thickness of ali should i use for a blanking
plate?
10mm perhaps? can i go thinner?
just trying to work out a whole list of bits i need made up

8 or 10mm,that would be fine.id think
thinking about it it depends on how big the hole is,if its only small go thiner than that 6mm should do it

Hole where the water is? IE hole in the water jacket. That stuff's under reasonable pressure. The thickness required will depend very much on
the shape of the blanking plate / number of bolts to hold it in place / clamping force etc.
10mm ali with a cork gasket and maybe a bit of blue will probably do the job but

hmm, ok, pictures... hang on. i'll see what i can find
see, i did have some 19mm ali to do it with, but everyone said it was too much. going to have loads of bits water jet cut, so re-thinking it as my
attempt with a jig saw and file was terrible

this is the bit i've taken off, its gasket is about 14cm across, 5cm tall. the hole in the water jacket is only about 25mm diameter.
my pc seems to have something against opening photoshop AND ms paint, i was going to put up a photo of the gasket, but i can't at the minute
i can do this one, where you see a bit of the round piece where the sensor goes

yeah the photos huge, but resizing is out of action right now... bear in mind the dimentions above
the passage below is something to do with the exhaust gas recirculation i think, which i'm doing away with as i'm running carbs. so the
opening in the water way is tiny compared to the size of the plate

Locost approch of What have you lying about.
Anything from about 5mm upwards will do the job IMHO
Did you know - Core plugs for a V8 Engine are only about 3mm Thick

That looks like the EGR valve holes to me..so it'll be exhaust gasses on one hole and the inlet manifold vac on the other.

how thick is a tin of coke? and that if you shake the can gets to pretty high pressure. not a true comparison though due to shape.
for a 19 mm hole 3 mm is more than planty so anything thicker than that will be more than adequate - also depends how many, size, how close the fixing
bolts are and if washers to spread the load are used.
think how thick steel core plugs are, then work out equivalent thickness of aluminium for the same strength.

sure is. but blanking them all off.
3mm ali? not arguing, but seemed a bit thin to me. could always go a little thicker to please myself, 5mm, then see how that goes i guess
cheers

Why not try the Omega/Vectra fix method? They use a coke can, with the original valve to hold it down. Chop the top off that, use the coke can and

^ erm, not entirely sure what you mean, but the whole thing has to come off as i've got about 2" space behind the engine before the
bulkhead. so it'll need to be a waterjet plate. thanks for the suggestion though

3mm will be more than adequate for blanking off EGR ports. As long as its flat. If you are unsure, use 5mm plate.
There's no real amount of pressure there, certainly not enough to distort 3mm plate.
