Went to work today. I found traces of the white (oe?) sealant under the red RTV that was on for the timing belt, and I assume valve adjustment, at 80k. Cleaned everything on and off the mating surfaces and hand washed the old rubber gasket. When cleaned, it felt like it had some life in it, so I'll reuse it. It turns out the black high-temp sealant I got is not OXY sensor friendly, and I have a new one going in soon. So I have to grab some RTV, plain blue, I guess.
As a side note, I will do the gasket, drive a week, drain the oil and then put the OXY sensor in a week later. Is that advisable to wash out the silicone?
A few questions-
How are the cylinders numbered, right to left?
It seem like for each possible 90 degrees of crankshaft, one cyl will have all 4 valves not "loaded" by the cam (loose to the touch), one cyl with all loaded and the other two will have two of each exhaust and intake "loaded". So, I guess you could adjust half of all the valves at once. I'll only do it on which ever cyl is at TDC... at a time. I'm confused about the positions, but think it's ok to procede. "TDC" means the valves are loose to the touch and not "loaded" by the cam and CAN be adjusted???
As for feeler sizes, here's the specs and what gauges I have...
Intake calls for 0.003" to 0.005" and I have .006", is that ok?
They are so tight now I can't get the feeler in at all. I was thinking to re-adjust them all at .006". (.001" out- loose)
Exhaust calls for 0.006" to 0.008" and I plan on using the .008" feeler...on the loose end of the scale. They all vary a hair in tightness with that gauge, and none of them currently allow the .010" gauge in.
So, my understanding is that the valves tend to tighten over time. Should I adjust them as described, loose to .006" and .008"?
Where and what do I use the torque wrench on? The posted directions say I need one on the list of tools, but don't give specs???
btw- my heads were cleaner than the ones in the instruction link pics, at 130k almost silver. Light stains around the pcv intake were soft and wiped away. PO was a 3k guy, a sprint racer who kept it for his wife.
This was the f/s pic 2 years, 40k ago...
