'94 camry missfiring - Toyota Nation Forum : Toyota Car and Truck Forums

I have a 94 4cyl camry that is only running on three cylinders at the moment. Ive been told theres a leak somewhere around the spark plug which is allwoing coolant to leak in around the plug. It can be temporarily fixed by taking out the lead and blowing compressed air in and around the spark plug to dry it out.

Is this an easy problem to fix?

To me it sounds like you have a Blown Head Gasket if coolant is leaking into the Cylinder. It's far from an easy fix. Only real way is to change the head gasket.

yea, thats what i thought. But the guy that looked at it said it was something to do with the sleeve around the plug? BS?

Are you sure he didn't say oil was leaking in around the spark plug, rather than coolant. That would be more common and wouldn't take a new head gasket to fix. If that's the case, you can try retorqueing the 4 30MM spark plug tube nuts that are exposed when the spark plugs wires are removed, to 17 foot lbs in 3 even passes. Many times that cures the oil around the spark plug problem. If that doesn't cure the oil leaking in, then you will have to reseal the spark plug tubes. Resealing them is still a much easier and cheaper job than replacing a head gasket. This is all assuming that the problem is oil and not coolant leaking in around that plug.
