 My engine is underpowered even by 914-4 standards, low compression one cylinder, bad clutch and back oil leak. So dropped the engine. Now what? Any suggestions on how to find out if its bad head vs cylinder? plan to replace pushrod tube seals and clutch as well as SS exhaust. anything else I should do? Thanks in advance. |

If you take the heads off, do a "spirits test". Pour paint thinner in them and see if the valves leak. If they do, you can take the valve out (need a valve spring compressor) and see if you burned one from your valves being tight/held open. A good valve will have shiny ring around the edge where it seats. A burned one won't have that. Chances are you find a burned valve on the cylinder that is low.
