Compression testers

[gordon stephenson]

There is a difference in cylinder pressures, petrol is rapidly ignited and causes a rapid rise in cylinder pressure, Diesel ignites and is a slower burn giving a longer push to the piston.

tyre valves don't have any problem at 350psi.
This gauge has a pair of tyres valves in it. I just chopped the rubber off the
brass bit and loctited it into the steel/aluminium bit and then screw the valve in.
Two valves are needed, a vent and the compression valve[as close to cylinder as possible].
1,000psi gauge wasn't needed, 400 psi is probably ideal.

Around 35 Bar minimum rings a bell for the Golf (though I'd have to look it up again to be sure)
Looks like there might be another addition to the projects list...
Best try to fix the faulty one first though I think...
