Re: valve adjustment on my d15b vtec what do i adjust the valves to (89HTACH)
you need a feeler gauge from a pars store, and then you need the factory specs on what to adjust them to. I know the d16z6 has .007-.009 on the intake side and .009-.011 on the exhaust side. Im not sure if they're the same though...

Here's a basic how to on valve adjustments: http://www.c-speedracing.com/h...t.php
I believe (not %150 sure) that the D15b shares the head of the Z6, so the clearance specs should be the same.

Once you get the cover off, you'll see the adjustment screws. The process is the same as the DOHC, but the access is easier. You don't need the special tool, just a screwdriver and box wrench. Put the feeler under the screw, loosen the nut, turn screw till tight, lock nut. Rinse. Repeat. Sounds like you might want to get a little help with the job though.

****. A little harsh. Funny, but harsh.
Remove your valve cover.
Turn Crankshaft to TDC (This is for Cylinder # 1. Aligns Camshaft Sprocket to TDC for Cylinder # 1 aswell).
For every 180* turned on the Crankshaft, 90* is turned on the Camshaft Sprocket.
Loosen the 7mm locknut for Cylinder # 1 and do all 4 valves. This means you need to loosen 1 locknut at a time, stick feeler gauge to proper spec on top of the valve and tighten it with a flathead screwdriver.
After checking clearance 2 or 3 times, tighten down the locknut to spec.
DEFINITELY use a torque wrench to tighten down. If you over tighten them, you can break the rocker arm.
Do this for all 4 valves.
Turn Crankshaft 180* (90* on Camshaft), this will bring you to Cylinder # 3.
Do same as above.
Turn Crankshaft 180*, this will place you on Cylinder #4.
Do the same as above.
Turn crankshaft 180*, this will place you back on Cylinder # 2.
If you're not sure what Cylinder you are on, remove Distributor cap and look at what plug it points to. Also, get a Helms. It helps you to see where EXACTLY 90* is at on your Camshaft Sprocket. Or, do it the ghetto way and stick a long piece of wire (like fence wire) and move the Crankshaft and see where the wire is. Once it reaches it's peak, it's on TDC for each Cylinder.
I know this might seem a bit confusing, but it's not the simplest thing to do. If you can't turn a wrench, don't do it. Pay someone else to do it.
