A favorite thread i like to visit discussing the Z head vs Y

Camshaft Specs
Special Note:You can use a D16Z Cam in a D16Y Head but you have to use the Cam Gear from a D16Z because it'll be a 1/2 timing tooth off..same goes for D16Y cam in D16Z Head,just use Cam Gear for a D16Y..Do NOT buy any aftermarket Cam Gear for a D16Y from a company if they only have one Cam Gear available for the 88 thru 00 Ds.I recommend and use a AEM Gear,they have the right Cam Gears for 88-95s and 96-00s

How to Adjust D16 Valve Clearance
CAUTION:Always rotate engine in direction of normal rotation(counterclockwise as viewed from front of engine). Reverse rotation may cause timing belt to jump time.Rocker Arms are made of aluminum and can be damaged if lock nuts are overtightened so be careful.
Note: Valves should only be adjusted when engine is cold with temp of it less than 100 degrees F.

Step 1...Remove Valve Cover.Remove Upper Timing Belt Cover.Rotate Crankshaft counterclockwise until No. 1 piston is at TDC of the compression stroke.Up mark on camshaft pulley should be on top,TDC marks should align with cylinder head upper surface or TDC groove should align with pointer on back cover..see pic below

Step 2..Loosen adjusting screw lock nut on cylinder No. 1.Adjust valve clearance to spec on all valves for No. 1 cylinder.Turn Adjustment screw until a feeler guage slides back and forth with a slight drag.Tighten lock nut to spec and recheck valve adjustment..Cylinder No.1 is done

Step 3 Rotate crankshaft counterclockwise 180 degrees(camshaft pulley rotates 90 degrees) Up mark on camshaft pulley should be on the exhaust side.Adjust all valves for Cylinder No.3

Step 4 Rotate crankshaft counterclockwise 180 degrees(camshaft pulley rotates 90 degrees) Up mark on camshaft pulley should be down(both TDC grooves will be visible again).Adjust all valves for Cylinder No.4

Step 5 Rotate crankshaft counterclockwisw 180 degrees(camshaft pulley rotates 90 degrees) Up mark on camshaft pulley should be on the intake side.Adjust all valves for Cylinder No.2

Step 6 ..Ensure crankshaft pulley bolt is tightened to spec


Timing Belt Adjustment
CAUTION:Always rotate engine in direction of normal rotation(counterclockwise as viewed from front of engine). Reverse rotation may cause timing belt to jump time.

Note: Timing Belt should only be adjusted when engine is cold with temp of it less than 100 degrees F.

Step 1. Remove Valve Cover.Remove upper timing belt cover.Rotate crankshaft counterclockwise until No.1 cylinder is at TDC of compression stroke..see above pic.Loosen timing belt adjuster bolt 180 degrees,see pic below.

Step 2. Rotate crankshaft 3 teeth counterclockwise on camshaft pulley to create tension on timing belt. Tighten adjuster bolt to spec.Ensure crankshaft pulley bolt is tightened to spec.Reinstall valve cover,timing cover and your done!

Nice to know on the D16's..
Thx

RyanEJ8

Good info

LANL02

EXACTLY what I was looking for. I thought it would take me a while to find all this information. Thank you.

Just a lesson out there for you kids.....the search button really does work and can give you mana from heaven.

RyanEJ8

You just added a bunch of **** that's going to be real helpful to me tomorrow.

ExospeedAMcrx

Dont Forget Andrew Yang's CRX with turbo D16y8 back in 1997/98.
was doing 10.2 or 10.4 i believe.

Wil

D-Man

Andrew Yang was that Fast? I couldnt find much on him and the fastest Ive ever found on him was 10.6s..but thanks that is also good new for me since Im using the Y8 head and I was getting worried I made a mistake between what Zex-Man said on that thread up above and the HP/ET West was making w/a D16A6. I'll keep looking for info on Yang...of coarse he doesnt post on HT right?

A Pic I found of Yang in action in 1999
