Rocker gasket - ABY

[Dave W]

After engine had been running unevenly for a while, an ex home tune/AA mechanic had a look at it. Oil was visible on the middle spark plug. A new rocker cover gasket set was ordered, and when replacing the centre part it was noticed it had gone very hard, hence the slight oil leak onto the plug. Car now runs properly.

Cam Cover Gasket PN

.... Oil was visible on the middle spark plug. A new rocker cover gasket set was ordered, and when replacing the centre part it was noticed it had gone very hard, hence the slight oil leak onto the plug. Car now runs properly.

I have seen an AAN with all FIVE spark plug wells filled with oil and was still running fine. The owner didn't even notice. That was surprising to me. But if you think about it, oil is not a good conductor. Ask what is inside of all those large electric system transformers = high flash point oil. That said, I do not advocate running with even just a drop of oil in the spark plug wells. The part number for this cam (cylinder head) cover gasket is shown for item 17 here:



There are no "rockers" BTW hence cam cover or cylinder head cover.
