Hello,

You will need to disconnect the battery to start, drain the coolant and when you get the heads off have them resurfaced. You can get the head gasket set at Rock auto or amazon.

Here is step by step how to remove the cylinder heads and the bolt torque specs.

Check out the diagrams (below).

Let us know what happens and please upload pictures or videos of the problem.

Cheers, Ken

This is a big job, do you have the required tooling and experience to do this work? I would not like to see you get started on removing the heads only to see you get over your head so to speak and stuck with a car half pulled apart. Do you have a work shop manual? As there is so much information involved it would take ages to write it all down here. Also, a manual will give you step by step instructions with pictures to assist, and I can be here on the side to talk you through anything that you do not understand. What is your took kit like, do you have a torque wrench?

What were the symptoms? With the engine part dismantled you cannot do any further diagnosis to see what is going on.

The electrode was wet with oil? Was it misfiring? Did you do a compression test? Or was the spark plug boot section wet with oil. I need to work out exactly what you have going on first.

Was the engine over filled with oil? I just think that there is another problem rather than a head gasket that has caused one bank to oil up. But as you cannot run the engine diagnosing the problem will be very hard now.
