Compression gauge for the home mechanic?

published by Mightyrollaman on Tue, 02/11/2004 - 23:06

I've finally decided to add a compression gauge to my tool collection. Can anyone suggest a good quality (not too pricey) example suitable for use in all vehicles? Also, where is best to buy them?

In my opinion the best type of compression gauges are the type that SCREW into the plug hole....this way you can do a compression test without having to have a mate/gf hold the gauge or crank the motor.....But after saying that the best type for a busy workshop is the push in and hold type because they are alot faster but take two people to use......
ABW make a good screw in type and these can generally be sourced from good quality parts shops.....I personally steer away from and do not use/recommend tools from Super Cheap
Most reasonable quality units will do what the home mechanic needs......a close if not exact static compression reading that can be used to judge engine condition...Snap-on make a very accurate one that comes with an assortment of fittings but as with all Snap-on you will be paying a lot for it

Thankyou very much two heads. Very interesting point about screw in vs push in. Are the screw in type a pain in tighter engine bays (I have a WB Statesman on gas)? I will investigate further....

Because the hose on the screw in type is flexible I haven't found a car that I can not use it on........one hand to turn the gauge head and the other hand to guide the threaded portion in and let the hose do the work.....might be a bit fiddly down the back under the air con box but not too bad.........If you want one and can't find one I should be able to source one for you ...........cheers
