If you have oil pooling in the spark plug wells from a leaking valve cover gasket or sloppy top-up, before you pull the old plugs use an engine cleaner such as Foamy Engine Brite(R). Hose the engine off while it is cool then start it up and run it to boil off the water. Any little bit of oil left after that is not a concern. You should put a little anti-seize grease on the threads of the spark plugs going into an aluminum head, anyhow. A little oil in the threads will serve a similar purpose.
All you have to do is take the ht leads out (or rail if you have one) take the spark plugs out, put a rag over the holes and turn over the engine. This will spurt the oil onto the rag. Leave open for an hour or so and the oil will drain away. Clean with a rag and make sure you clean the plugs and leads too. Replace and your car should run much better than before!
I just got spark plugs from a local napa store and the gentlemen told me to gap the plugs before installing. .032
plugs can get bent in shipping! it is best to check gap before installing.
remove the coil packs then the spark plugs dont just drop the plugs when installing this will damage the electrode
Ensure that the engine is cold. Disconnect the wire from the plug. Clean the plug area with an air canister. Turn the plug counterclockwise to remove it. Calculate the proper gap before installing the new spark plug.
the spark plugs should be gapped when you buy them between .050 and .055 but check each plug before installing
I recently degrease my wifes 1990 miata, and had the same trouble. i found that being twin cam . the water had gotten down in to the spark plugs. I first removed the plug leads, then blew out the water with compressed air. then removed the plugs and wiped clean, with a rag down the spark plug holes, then finished with a clean of contact cleaner , then reassembles and yay no more splutter . so spark plugs were shorting cause it was all wet down in there ?

I understand that, originally, receptacles had 'nipples' that locked into the holes in order to hold the plugs in place. Although I don't think this is still the case. Anyone else out there to confirm this?
remove the plugs from the drainage holes located in front of the rear tire wells

They go into the sides of the block to seal the casting holes.
