Compression tester

[Junk]

Need to finally buy a compression tester and guess I need a start button too. How about recommending one up for me? Don't need bells or whistles, just want a damn good tester. Besides using it on the truck, will soon be buying a bass boat so will be using it for testing out a few outboards as well.

So no one has any input on a compression tester?

Not that you would want. Mine is from HF. It works, but I don't know any better- it may not work well, if you get my drift. If I were looking for a decent one, I'd check out NAPA, unless I just wanted to bend over and chase down a Snap-On truck. Bring your own lube of choice if you go that route.

I have used one similar to the craftsman with good results. Works well wet or dry and is not too spendy.

Craftsman Compression Test Kit - Model 47089 at Sears.com

I also have used this starter button.

I haven't used my compression tester since I bought a leak-down tester. Much more useful.

Thanks for the info. I'd still like to go the compression route as I'd like to be able to do a more thorough prepurchase investigation. I think it would be one thing to convince the owner for a compression test but asking him if I could pull the valve cover, adjust the rocker arms and hoping he has air available would be pushing it. I'm not saying I disagree with your post, in fact I appreciate the input, but just indicating why I'm looking at the compression tester.

I have an old one from sears that I stole from my dad...The spark plug end has two different sized threads on it (small diameter and large diameter) with an o-ring seal. I recommend the thread-in type opposed to the type you have to press against the spark plug hole. The gauge end has a check valve with a release pin so the gauge reading hold pressure until you push in the release pin. The hose connects to the back of the pressure gauge, not the bottom as so many of them do. I think this makes it easier to install the hose (you can spin the gauge face like a handle) and easier to read.

Ah, OK. Good point and reason. Ya, it's much easier to do the compression test, in fact you can do one on a non-running engine. Another down side of the leakdown test is the engine has to be up to full operating temp to be accurate.

I just picked up one from O'Reilly's. Worked fine for checking a 22RE I was getting ready to pull. Only around $30. I compared it with one from Napa - looked similar but $20 less.

I got my stuff from AZ I think. Just the basic trigger starter and basic compression tester. Works.
