Alright I have a compression test numbers! Per all-data standard compression is197 psi.And min is146 psi. Difference between cylinders should be 28 psi. Here's the facts . I remove all the spark plugs for a compression test and disable the fuel injection and spark. Fuel injected into the cylinders during testing can skew results. WOT gives more .

Expected results vary a bit depending on the compression ratio, which varied a lot over the years, but a brand new engine might be in the range of 190 to 200+ psi. Mazda's . My results seem to be good, and someone on ClubRoadster.net has said anywhere between 160-190psi is 'good'. His results were 179-180-172-181 on a 1.6 1992 .
A compression test is useful in detecting major internal problems, such as broken pistons/ringlands, damaged cylinder wals, or stuck/bent valves. These problems are indicated .Anyways, it was mentioned that a compression test can give a good indication to see if you have any leaks. Test was done with all plugs removed, and wide open throttle. The results of my . When doing a compression check, how much of a difference will a cold engine vs a warm engine affect the numbers? Will a cold engine make the numbers higher, lower, or would they be so skewed they can't be trusted? I'm deciding whether or not to keep the engine so I did a quick compression check today, but didn't have time to warm the engine. In the Miata configuration the coolant can take the path of least resistance and somewhat bypass the back of the motor. .

His results were 179-180-172-181 on a 1.6 1992 Miata. I also documented the condition of the plugs which seem to all look healthy (light grey coloured ends). Bearing in mind . The Suspension package, and particularly its grippy tires, give the Miata a quick-steering, glued-to-the-road feel. Grip matched that of the last test Miata (also "packaged") at 0.88 g. A good number. A compression test is useful in detecting major internal problems, such as broken pistons/ringlands, damaged cylinder wals, or stuck/bent valves. These problems are indicated when on cylinder is significanly lower thatn the others. But a compression test is NOT very meaningful for actually determining the general condition of the engine. bill
I decided to do a compression test today since i usually do one before i buy a car but anyways i was pretty happy with the results but havent found exact numbers for an acceptable range but just going by what most my hondas were suppose to be in then i expect being similar displacement and such to be a similar range. 2000 Miata LS w/ 147,592 miles with approx. .

Either your car is going to misfire or it's not going to start. Thankfully, testing the engine compression, in your 1.8 Mazda Protegé, is not that hard. What makes the engine compression test easy is that the spark plugs are easy to remove. On a 2000 JRSC'd Miata with 40K miles on it how do I perform a compression test? I know the basics but do I remove the fuse for the MPI and if so where is it? Do I unplug the coil lead to avoid shock and where is that? I am inspecting this car for purchase and I really want to know the cylinder compression.

Doesn't appear to burn oil and clutch still grabs well but weeps/drips enough oil to add ~0.5 quarts between oil changes. Within the last 2,000 miles I installed a FM downpipe, FM Intake, and tuned on MSPNP3 at 9.5 PSI. Motor runs strong. Just picked up a U.S General compression tester at a garage sale and performed my first compression test.
I performed a compression test earlier to day with the help of my father. We ran the car for roughly 10-15 mins to let it warm up and a few mins after, we began our compression test. We tested each cylinder 3 times (cylinder #1 twice in a row, cylinder #2 twice in a row, etc. -- then one last sweep, cylinder #1, cylinder #2, etc). Spec compression for your engine is 192 psi, with 135 psi the low limit and max alllowable difference between cylinders of 28 psi. But this needn't be taken as absolute, as some factors not relating to engine performance can affect the numbers, such as: Test procedure used -- some practices return higher or lower numbers, and the accuracy of the guage -- I've seen .

2000 miles later, the coolant tank was empty for a second time. In both situations, I checked the radiator and everything was fine there, full to the top. I would like to start investigating with a compression test and then move onto a pressure test. No .

According to the manual, this is "as new" compression, so you guys who have nearly 180 lb after 150,000 miles are doing very well. Hells bells, these motors are tough !!!! The relatively small increase from dry to wet compression could be the result of oil control rings oiling the compression rings ala a wet test,so I think your oil consumption is due to stuck oil control rings. One leaked quart of oil will make a rather large mess, so I doubt the lost oil is leaked. Let us know the leakdown numbers. First thing I want to say is, that's a great way of presenting compression test results; clear, readable, and easy to check everything! From what I am reading (and I am just reading as I go here; I don't have lots of compression test experience, so take what I am saying with a grain of salt), you want to do the compression test without fuel; so if you aren't sure . We get some expected, but bad numbers from this test.HOW IT HAPPENED: https://youtu.be/AJTBG5ZY0dMLet me know what you guys think, comments and suggestions a.
Pumping fuel into the cylinder during a compression test 'could' cause a lower than normal reading on the wet tests. The gas would thin the oil and allow more 'blow by' during the test creating a false low reading on the later cylinders. On the dry test it may or may not affect the reading depending on your perspective on the matter.Today I decided I wanted to compression check my Miatas engine to make sure it was still healthy after a lot of miles. Overall pretty happy with the results .
Miata NB Compression Test
Break 'um in the way you use them. Slow and careful break-ins often never seat the rings. First 50 miles often tells the story. Race engines have good compression or they are scrapped/rebuilt and many never see the total miles some people think of as 'almost broken in.' 9. If compression is low, pour teaspoon of oil in cylinder and recheck. If compression improves, it's the rings/piston/cylinder wall. If compression stays low, it's the valves. If the compression in adjacent cylinders stays low, the cylinder head gasket may be defective or the cylinder head distorted.
