Ya know, I was just gonna post about loose push rod V8s. They're not like this hi strung straight 6.

Maybe a valve adjustment will net one HP on a 440ci V8 or really change the power curve, but not on this car.

Also worth noting that setting valve lash can have more (not a lot, again) effect on rich/lean and when the power's made - not that more power is made because of retarding/advancing the cam.

Like albino already alluded to, we've got Vanos anyway.

Might wanna choose another thread Brett.

Also, I don't like what you said about me responding the way I did because it's coming from you. The only bias I have is that I expect more from you because you know more about these cars than most and are a great DIYer. I don't have any other bias than that about you.
The thread was not the point. Your post was.

I don't get your point I'm afraid.

The point was you have already been presented with this topic. You don't take it seriously.


What is it that you think aftermarket cams do? Playing with the lash is a free cam change, just on a much smaller scale. A few hp here or a few torque there versus 5-10x that with a whole new cam... or does the VANOS negate that too

I was actually the one arguing earlier that a tighter clearance is like a hotter cam!
My other contention is that it's a very marginal amount.

We tell people they're in their heads when they claim to feel a 3whp increase from an exhaust, but now a .5 or 1 or 2 hp from a valve adjustment (one where you're adjusting all 24 valves I guess) is something?

I'm over it. We're OT anyway. Bottom line to the OP, it's possible to not need any adjustment, but more likely that a few need it. Worst case scenario being a little out of spec is a fractional loss of power and maybe running a little rich/lean. There are people who go 100k without valve adjustments and their cars are "fine."

I'm replying to this because of a later edit you made after a post. In bold is how not to use the feeler gauge. Selecting the appropriate gauge that fits the gap and feeling the resistance based on whatever analogy you subscribe to (as defined in the video) is the correct method. The correct method is how the OP described it and this is why I quoted Ian.

As far as the power from valve lash. Yes agreed, it has gone off topic. I was only pointing out the long time accepted understanding in basic form. Anyone who wants to understand more should take the time to look up the pros, cons, and realistic expectations. I'm not out to be the educator of that, which is why I said, use whatever you feel is best.

If .178 (intake) feeler fits in the gap, you know you're not too tight. If it doesn't slip in, you're too tight. If .229 feeler fits, you're probably too loose. If .254 fits, you're def too loose.

That's what I meant by go no go.

You're getting too pedantic and over complicating it or have too narrow of an idea of how to use a feeler gauge. If you want to decide the tolerance by using one feeler and feeling the resiatance, good for you. You can also use multiple feelers to deduce the tolerance by wether or not a feeler fits.

You're over complicating this and just saying exactly what I already said and posted a video of. Please watch the video. It is explained properly and matches what the OP said.

Go or no go is not an appropriate method to describe feeler gauge use. Someone with no knowledge can interpret that into "if I can cram this in, it's good to go".

Jesus Christ Brett. Where did I or anyone say anything about cramming it in? I said "slip" and "fit." I know how to adjust my valves, thanks for your concern

Get over yourself. I'm not out to teach you anything. I posted to describe the correct understanding of use for others. You chose to respond with your go or no go nonsense which required clarification for OTHERS. Own up to your incorrect description and move on.

FFS. I'm done here.
