Hey I've got an S5 NA short block that I'm told is good by a good friend of mine, But I'd like to test that the coolant o-rings don't need replacing before I do all the work putting it into the car. I was thinking of capping all of the coolant passageways, & then leaving but one open, the highest one, probably the thermostat cover. I'd then fill with water, & cap w/ a piece that has a valve on it, which would allow me to pump it up using a bicycle pump, or similar device.

Will this be a sufficient method? Is there a better way to do this? Thanks for the help.

I should add- looking through the Leading plug holes, both rotors look quite dry, w/ no corrosion or rust/water, & just a slight bit of oil residue/dampness near the apexs of the rotors.

That method should suffice, but let's be realistic, you should take the motor apart and check tolerances and replace those seals before you put it in the car.

Pineapple racing sells a tester to do just that. It bolts up where the waterpump would go

honestly, the more i think about it, the more this is what i'm leaning toward doing... Probably going to break it open on one of the next up coming weekends. Thank you for the help!
