#106063, "Compression test results"


          

Hey these seem not so great/weird to me.

Test 1 dry

170 170 180 135

Test 2 wet

180 210 205 260?

I first did the dry and checked a couple of them twice to make sure readings were right. Then I added a little oil, added a little too much to cylinder 4 though, would that cause it to go so high? It seems to me like it would be safe to say I have some worn rings especially on cylinder 4. Anything I can do to help this without rebuild? I hear about seafoam every once in a while would that be good to use or can it make things worse?

Another thing, afterwards I got a CEL, did a keydance got codes 12, 43, 43, 55. Two 43's that seems weird to me. I haven't reset the comp yet though to see if they still show up.

Well, you can either re-ring or you could re-ring those are your only 2 options to fix the problem. Make sure you have a machine shop look at the block and at least hone it to make sure its true for a good seal.

Seafoam cleans inside your engine it doesn't make your rings expand lol.



2 sets of injectors is better than 1 =)

I know lol, some people claim that it can increase compression with old rings, how this would happen I have no idea, I think that it would just make it worse. No chance on it getting re ringed, just going to live with it, doesn't bother too much to drive, just wont be putting the extra money I had been thinking about putting into the car.
