I did a compression test on my h22a1 cylinders 1,2, and 3 were at about 225-235 but when I tested cylinder 4 it was only at about 170-180. I'm pretty new to Hondatech and just kind of wondering where I should start and what I should do. I know my friend has a leakdown test so I figure that's my next step?

 

Yep. Compression tests tell you how the cylinders compare to each other. If one is out of spec, a leakdown test is in order to see WHERE the lost compression is going.

 

This thread isn't directly related to machine shop work and assembly it's diagnostic.

Have moved to misc/tech as it doesn't have specific car information, just a motor.

Thanks.

 

Thank you
