I can guess
Cruddy

Those plugs don't match that cruddy header either

Indeed. Thats why im hoping its just a valve seal that went bad just after i put the new plugs in.

Rent a compression tester and see what you get for numbers. Might be ebough oil leaking to make this inconclusive.

Perform the cylinder balance test part of the code reading process and see if it comes back with a cylinder on that side. Again...might not give you a result if the cylinder is able to fire ok.

But, honestly thats a lot of oil coming down. I wouldn't be surprised if a cylinder wasn't firing on that bank. These cars drive perfectly fine on 7 cylinders and you'd never know it

Alright ran compression....by cylinder in numerical order 140/140/144/150/142/140/142/however number 8 does not hold pressure. It will go up as the car is cranked (up to about 160 or so, then when we stop cranking, the gauge pressure drops slowly to zero). We did the test to #8 a few times, same result. Also checked snugness, it was good. Checked fittings, good. This was a dry test, we did not do the wet test.

What do yall think? Googled it and its pointing towards the valve guide. Thats what im hoping as its the easiest to fix from what im hearing.

My compression gauge will hold pressure untill you hit the Schrader valve, am I missing something?
What did the #8 plug look like?

Could be valve seal too
