mrmark Posted July 18, 2012 Report Share Posted July 18, 2012 I just did a compression/leakdown on my A14 and #2 has 90% leakage thru the rings with 30lb compression. All the other cylinders are up around 220 lbs and less than 5% leakage. No clue how many miles are on it and i'm pretty sure that my head is shaved to get up to 220 lbs? but not sure. So, do i tear down and see what I have(probably will do this anyway) and then try to find a match and rebuild the bottom end. Or do I just suck it up and do the KA24E swap I've been itching to do anyway? Quote Link to comment
mrmark Posted July 18, 2012 Author Report Share Posted July 18, 2012 BTW, the car doesn't smoke or make odd noises, just a little low on power. Quote Link to comment
DanielC Posted July 18, 2012 Report Share Posted July 18, 2012 D F W Y T. Don't **** With Your Transportation. I would remove the A14, and see if it is an easy fix problem. Get the car running again. Then work on getting the KA 24 E swap ready to go, while your car is running. Quote Link to comment

DRIVEN Posted July 18, 2012 Report Share Posted July 18, 2012 I would try a product like Sea Foam or maybe Marvel Mystery Oil to see if you can free up the rings before tearing into it. All the A-series engines I've had apart had alot of carbon around the rings that caused them to stick in the grooves. Can't hurt anything and costs less than $10. You might not get the compression all the way up but might improve it enough to delay a re-ring for a while. Also, if you have access to a bore scope try to look inside and check for a burnt piston or badly grooved cylinder. Quote Link to comment
mrmark Posted July 19, 2012 Author Report Share Posted July 19, 2012 Anyone ever try Restore Engine oil additive? I figure it's worth the 8 bucks to see if it raises compression. I have my doubts but if it works, I'll do the swap when i'm ready. Quote Link to comment
Z chopper Posted July 19, 2012 Report Share Posted July 19, 2012 I have used lucas oil stabilizer and it seemed to help cure low compression for a short while. go full out build up the ka and swap it in asap Quote Link to comment

I have my doubts but if it works, I'll do the swap when i'm ready. I think the theory behind Restore is to "fill in the scratches" in the cylinders to raise compression. I would suggest using something that is more solvent based to dissolve the carbon and free up stuck rings. I've used Sea Foam with good results. I pulled the plugs and poured some into each cylinder and let it sit over night. In the morning I cranked the engine over to make sure there was none left in the cylinders (It had all seeped past the rings). Then I reinstalled the plugs and fired it up. The last step was to pour the rest of the bottle down the carb throat (while revving it up a bit) and go for a drive. Expect a LOT of white smoke out the tailpipe. Quote Link to comment
ggzilla Posted July 21, 2012 Report Share Posted July 21, 2012 You won't need to rebuild the bottom end. Just take the head off and inspect the cylinder in question. Probably has a broken ring, might have a little score on the cylinder wall. Mic the cylinder carefully and if in spec, just put new rings in that hole and keep driving it. Quote Link to comment
