2002 corolla (now 91000 miles) makes rattling sound


Thats good that you are getting a second opinion. A Toyota dealer will be able to check it and see what the noise may be. See what they come up with. I dont think a worn timing chain or guides would cause a low oil pressure problem. But, if it does indeed have low oil pressure, that is a serious problem.

Wet Plugs


If the oil was still wet it probably wasn't coming from inside the combustion chamber. Oil in the combustion chamber would show up on the plugs as white ash (usually). It has been my experience with those toyota motors that the oil comes from deteriorating o-rings that seal the valve cover to the spark plug tubes. They're not very difficult to replace. Remove the valve cover (you'll need a VC gasket) and there are 4 big holes in it that fit over the spark plug tubes, which you should now see sticking up out of the head. Replace the o-rings around them and you should have no more oilly plugs. I don't think this really affects the performance, but I can see where it would cause plug wires to fail prematurely.

Car/1990 Toyota Corolla


If Biggy1 has described it right, I think when you remove the WIRE to the spark plug ( not the plug itself ) and oil jumps out, there is a cylindrical seal that needs replacing and one does not need to even remove the cylinder head.
I have the same problem with my corolla. On the other hand if Biggy meant when removing the SPARK PLUG oil was on the contacts....
