1997 Civic LX Compression
Hi,
I had my mechanic check the compression on a 1997 Civic LX, he said it's fine. when I picked up the car, I got the printed results: all 4 cylinders 160 psi (give or take 1 psi). The mechanic wasn't there, and the cashier didn't know the spec values. From the message the mechanic left on my voicemail I understand it''s OK, but I was just wondering what those values should be for a good 1997 Civic LX Engine (i.e. when it was new, and for a well taken care of engine). Thanks |

160PSI is a very good reading... I would think new wouldn't be much
higher. Don't think you have any problems there.
