Compression Test and Inspecting Spark Plugs

[nwbDSM]

Hi,

I just did a compression test. Here is what I got

172, 175, 175, 178

I only know that it is okay, if the differences across 4 cylinders are not more than 15%. I'm new to the DSM motor. Are these numbers good enough or too high?

I also got a chance to look at the old spark plugs. Here is what they look like.

What does it tell you? I don't know how to inspect the spark plugs, too rich or lean?

Thank you

For one thing, it tells me you're running the wrong plugs.

Try some NGK BPR6ES gapped to .028".

Your compression numbers look good. : http://www.dsmtuners.com/forums/articles-engine-fuel/338152-compression-leak-down-testing.html

You also need to fill out your profile and include any mods done to your car.

Whatever plugs they are, they aren't what should be in the car

The plugs are NGK BPR6EKN. To my excuses, these came with the car. I already got a set of BPR7ES waiting to be installed.

I thought I just did update my profile this morning including a picture with my mods. I'll double check again later. Weird.

Thanks for a quick reply.
