Has anyone taken a compression test.

My '28 showed 59-60 lbs across all 4.

Sounds good to me.

Any comments or opinions?

Thanks,

SteveG

I plan on doing one tomorrow night.  I'll let you know where I'm at.  59,300 on the clock and a broken speedo cable sometime long before I got it.

That looks good to me. Mine had 65 accros the 4. Makes me not want to rebuild the engine.
As long as the compression is even between the 4. Then all is well.

I think mine is in this same range.  It's been awhile, but someplace between 45-60 sounds OK to me.  I think the main thing is consistency from cylinder to cylinder rather than a higher value. 

My 2.5 cents.
