Pressure testing block
Posted: Sat Feb 11, 2023 5:09 am
I have a 3.9 block that Im trying to test . I have made flat steel plates with 2mm thick rubber stuck to them to blank off holes , fitted a pressure gauge and put 30psi in .
The gauge doesnt move at all for an hour but had dropped to 20psi after another 4 hours .
I have done the soapy water thing round all my fittings and the tops of the liners and cannot see any evidence of a leak .
So far I have only done one side of the block .
Is this much of a leak to much ?
Thanks
