Has anyone here used one of the Pressure testing plates that one of the vendors sells. Part # T3000-X Any idea if the rubber coating holds up on them? If you do not want to post here, PM me. I am looking to get one. Thanks, Dan
Dan a lower cost way is to just use a 1/4" thick sheet of rubber type material. Punch out the bolt holes and use the head to hold on. The plate for the gauge and hose connection can be made out of 3/16 plate material and mounted to the water inlet.
We have one at the shop made for Model A's, it's been in use for a number of years.
You are only working with a few LBs of air anyway. For looking for cracks in the cylinders, turn the block on it's top or side.
No one here has one of these?
What is a "pressure testing plate"? Are we talking about a compression guage for testing cylinder compression?
O.K.....I'm just a little bit more "dense" than usual this morning I guess. In re-reading and considering Mark's post, it sounds like a device to pressure test the engine block for water jacket cracks and such in the engine block,....sorry,.....harold
I made my own
Here is link to the tool in question.
Andy: I was wondering how the rubber coating would hold up on these. What do you use to seal the plate? Did you put cut outs for the valves like this one? Thanks, Dan
I have one for A's and one for T's. I use both extensively and will never have another block magnafluxed. I have had blocks checked with magnaflux that showed cracks that turned out to be scratches under pressure. If a block don't show a leak at 40# pressure it won't leak.
I also use mine with a vaccuum pump to make small repairs on blocks that have small exterior cracks.
I have cutouts for the valves and pistons, but I generally just have a bare block anyways. I use a head gasket. I don't know how much air I use, don't have a gauge in line. Too much will pop the frost plugs. I pressurize it and spray the block down with soapy water and look for any bubbles, hasn't failed me in last 12 or so rebuilds.
