Re: [AlbinVega] Compression testers...(read this one instead)

Hi Pat,brbr

I'm really liking your idea...brbr

I just spent the night on the net finding out all about adaptors and gauges. So it sounds like you just purchased a standard gasoline engine compression gauge which goes up to 300 psi. The diesel ones usually go up to 1000 psi.brbr

You know, i just now looked in the MD6A shop manual that I have and it looks like it says 23-25 kp/cm2 (327?355 lbf/in2). That looks like 327-355psi to me.brbr

If it is 327psi, do you think I can get a diesel gauge and do the same technique you are talking about?brbr

The orientation of the MD6A in my Vega will prevent me from putting my full body weight onto the gauge. brbr

ghbrbr

ps. One idea I did come across that was interesting... Some diesel mechanics will just take an old injector and have a compression gauge fitting welded onto the end and use that as an adaptor.brbrbr

Hi.:
reading all these ideas on how to measure the compression
makes me think of dialogs between Flintstone and Barney.
They couldn't have said it better.
Whatever you do, just please disconnect the water intake to
the engine. Remember, whenever you turn the engine without
having ignition, the water pump still sucks in water, but
the exhaust doesn't spit it out! If you keep running the
engine- whether manual or with the starter, the water will
back up and eventually enter the engine. Close the
sea-cock, you're doing yourself and the engine a favor.
