Just pulled head. Comments on valves please

[juntjoo]

I've never done this and supposedly my valves are bent but this is foreign to me at this point. Can you guys determine anything from these pics? I included some of the pistons too if there is anything to gather from them. Thanks

is it supposed to be that dirty on top of the pistons? There is all kinds of debris.

Okay, just learned about the 2 nut trick.

So do these stock studs often break? or do you guys only upgrade them for turbo + setups?

Since you are an NT you should be ok.

To do a quick check of the rings,

1) roll the pistons so all 4 are at the same level, mid stroke

2) take a quart of engine oil, and pour equall amounts on top of all 4 pistons, appox 1.5 inches

3) walk away for several hours, to overnignt

4) all the pistons should have appox same amout of oil in each bore, if one is down way more than the rest, you will have ring issues in that cylinder.

Thanks. No leakage whatsoever.

The problem with the stock studs is that over time they tend to stretch. Most just go ahead and replace them with ARP for the peice of mind. With you being NT unless you have plans for a turbo in the future I think you'll be fine with stock.

This is a great suggestion. I'll have to remember this method for future reference.
