Rebuild or swap?


Recommended Posts

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?

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.

Looks like he needs to rering it or "Rebuild" it......

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.

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.

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.

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.
