If oils getting into the cylinder then its the oil ring on the piston has broken,[con-rod needs taking out to get at piston rings } or the oil seals on the valve stems are u/s,,to due that job,take cyl head off ,remove valve collets and springs then you can get at the seals

Oil in spark plugs


If you saw fresh oil, you were looking at valve cover gasket-seals leaking into the spark plug tubes.

crankshaft sensor, or computer on toyotas then it was usually the distributor or the computer, but the crankshaft sensor might be bad too thats what helps to get you spark.

it could be your transmission not ingaging into 3rd or 4th gear. or your plugs or plug wires were damaged in the process.

I have a 1991 Toyota Corolla. I have put new spark plugs, spark plug wires, rotor button, and distributor cap on it. I have also put a new battery in it and had the alternator tested. I can't get it to...


you need to determine if you have spark or not. if not, is the cam turning? does it sound normal whan turning over? take the oil filler cap off, and see if cam turns while someone is cranking engine. if not, the timing belt is broken. if you do have spark, then the engine isnt getting fuel. you may need a shop to get further into it.

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.

You need to do a compression test on the engine cylinders. It appears one of the cylinders is not firing and dragging the rest of the engine down in power. The compression test will show if one of the cylinders has a problem.

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....
