2.3 Compression Test Specs
I have searched through the forum looking for the compression test specs for a 2.3 engine. I've got one in my sites to buy. I have a compression tester and want to check a couple of cylinders before I buy it. What is the acceptable range of pressure? The truck has 145,000 miles on it.

Go ahead and check your compression. Do you have any reason to suspect something to be wrong?
Really, what's most important is that compression is the same on all four cylinders. If you have one that's got less than 80% compression of the other three, that points to a problem.

I'm looking at buying a 94 with 140,000 miles on it. I haven't seen the vehicle yet. Thought the compression check would be an indication that the engine would be ok for a while. Not the final answer, but if it was way low, or not about the same, it points to a problem.

If the engine is running smooth as silk, then there's no real need to check compression. Testing the compression is a diagnostic check when there's a problem with the way the engine's running when everything else checks out ok. A lot of us will check it while changing plugs because its an easy 'while your at it' kind of simple thing, but again, usually only if the engine was running poorly to start with.
If you start a thread on what to look for when buying a high mileage used truck, you'll get hoards of advice, hee hee. I believe that there is an older thread about it, but I cant think of a keyword that would dig it up.
