<VV> Fix or rebuild 65 110hp engine?

[shortle]

Hi Paul, You need to do more tests before condemning the piston rings. If I was in your position, I would make sure the valve train is proper (valve spring, rocker arm, push rod, etc.). You will have to remove that valve cover anyways so I would start there. Have you done a leak test? (to determine where your compression loss is). Were there any symptoms to this? Rings don't just fail all at once on 1 piston only. Let us know what you find. Timothy Shortle in Durango Colorado 81301

>Folks,
>I have a 65 110hp engine in my convertible. I have had this engine since a complete professional rebuild 1980. Today it has probably 20,000 miles (since rebuild). It sat for long periods without being started back in the 80s and 90s. It now has a bad case of blowby which I have isolated to Cylinder #1 through a compression test (0 PSI on 4 different tests). I suspect broken ring(s) on #1. It took me from Kansas City to Denver and back last summer and ran OK but it seems to be deteriorating. It won't idle in drive now. I can drive it but have to put it in "N" at a stop. So here is my question. I'd really like to just fix the problem with CYL #1. By that I mean replace the rings on that piston. What kind of problems am I going to introduce? What are the ramifications of just doing the 'repair'. Comments/opinions appreciated.
