Is 120psi compression too low for 2004 Toyota sienna


The most important part of the compression test result is how even the cylinders are. That is, the lowest cylinder should be at least 80% of the highest. So if the highest was 120 lbs, as long as the lowest is 96 lbs or more, the compression is OK.

Good day I want to find out, what is my compression test results on a Renault kangoo van 1.4 8V 2005 model


In pounds, all should be 140 LBS psi more or less and all within 5 lbs one way or the other. psi=pounds per square inch - measures on a special gauge for this reading. Hope this helps. http://www.auto-tune-up-and-repair-options.com/worn-motor-treatment.html

First have the saw checked for compression. It should be between 115 lbs and 150 lbs. If the compression is good, check sparkplug, air filter and fuel settings
If this fails, have your dealer do a pressure / vacuum test.

Have a compression test done on the unit. Should be around 125 - 155 lbs of compression. If compression is good, may be the carb.

Hard to start any weather


Generally 2 stroke equipment that is hard to start has low compression. I would advise you to do a compression test and ensure that you are getting between 100-150 lbs of compression. If not your saw needs a piston, jug, and piston rings. If your compression is good I would suggest checking your fuel filter and carburetor.

# 4 cylinder 30 lbs compression


it indicates a sticking valve or lifter. you will have to do a leak down test to rule out the piston rings for that cylinder. most engines should have 140 to 160 cranking compression. a low compression on one cylinder indicates a bad exhaust valve. have a good day !!

Car not starting right


My first thought is low compression, run a compression test and see what the values are, if they are below 75 lbs. then you probably have lower end problems, if they are all above 100 lbs and one or two are at less than 80 lbs, you probably have a cylinder head/valve problem. Hope this helps, let me know.

Compresshion specs


Compression tests are almost always done in psi, not ft-lbs - if you get the gauge from a parts store, it's likely in psi.
