Showing my nievity a little bit, but in the buying guide it suggests you get a compresstion test done. What's that all about and what readings should you get!?!

 

Thanks,

Compression test will check the compression of each cylinder - It is a fairly easy job - no more than changing all the sparkplugs coz that is basically what you do - insert a compression tester into the sparkplug of each cylinder and then crank the engine.

 

What it will tell you is the and indication of the state of the Pistons + Rings, Cylinders and Valves / seats Etc, basically it is a good indication of the internal condition of the engine which can't be visually inspected without a teardown.

 

Nissan reccomends Compression figures should be :

 

TT:

128-171psi

NA:

142-187psi

Maximum difference across cylinders 14psi

 

If the test does fail you can do further things to see if compression improves to give you and indication of the problem.

 

Enjoy.
