Does each valve pair have to be exactly the same?
On the front bank, I have one intake and one exhaust that is one feeler gauge tighter than the rest. None are looser than specification. I'm using my own metric feeler gauge set.
I dread the rear - that's the bank that I think I've got problems with.
I didn't do the valve adjustment at 210K miles, and over time I've had one cylinder that seems to stop the cranking - even with a new battery, it will literally stop cranking. I also am burning oil, and it could be related to the cylinder locking problem (drain-down on a valve guide?). I'm running richer than the computer tells me too - it will reek of gas after a week of daily driving, but not after sitting for months (which I think is why I have a slight rod knock). Yes, I replaced the cats, and the new ones behaved the same - OK for a week, then couldn't keep up anymore. And, it has a consistent hesitation from 2K to 32oo that has been getting worse over time, despite me doing everything else for the 60K (along with the new cats and cat-back). It pulls hard to 7600 RPM (well it did until I heard the rod knock), so it's not a breathing issue overall.
The front bank appears to be fine, all within specifications, though as I mentioned two valves are slightly tighter. I really hope I find a badly out-of-spec valve on the rear bank to justify the engine's behavior.
On my old '94 Honda Accord, all my Plymouth Crickets and Ford 2.6L/2.8L/2.0L motors, it was easier to get them exactly the same. I don't think I'll have too much trouble with this (first time doing it though), I'd like to get guidance as to the necessity.
