Valve Stem Seal Replacement
So gonna go through this process and wondering which type of valve spring compressor is recommended for head on engine job. The lever arm version or the wind down bolt version. Winddown is convenient as it frees up a hand when under compression - main issue is fitment?
My theory is this is fouling plugs over time and we get the smooth running mess. Plugs do look on the oily side of good on that bank - and I get the occasional blue puff on cold start.

Only the press down will fit due to the springs being so far down the valve spring hole. I have done it a few times swapping springs out with the press so it is easy but for sure TIME consuming.
