Thread: Overheated, Low Compression Cyl #3

Overheatign usually has little effect on these motors. Especially if it easn't an extended brutal beating overheat.

I'd try plug/plug wire/coil first and ensure that the compression test was accurate. I've seen some goofy compression readings without other issues ...typically because our valves like to carbon up.

IMHO…

1) Replace both coolant elbows, get rid of the Dexcool if you haven’t already.

2) no

4) I’d just do the front.
