First valve adjt on my 99itr today , it went pretty well , back to spec now , but all intake were around .009-.010 exhaust .010-.011 was it really tight or really loose ???
lmk thx

 

Thats loose.

Spec is
In .006
ex. .007

 

 

Wow it was really loose then ! I`m glad i did this !

 

Mine were all lose as well. Exhaust note changed considerably after the adjustment too. No more crappy Subaru gurgling at ~2800rpm.

 

Yup mine sounded more like a JhonDeere lol . Really nice and smooth now

 

.009-.0010? That is a huge range (.008"). Typically the range is .002".

.0010-.0011? Those values are small with a narrow range (.0001"). If you actually set it to that, you will end up burning your valves with clearances that tight.

Are you sure your measurements are correct?

 

No no sorry my bad ,big typo , i set it at .006-.007/intake and .007-.008 on the exhaust ,but i found them before the adjt between .009- .010 roughly all over !

 

I saw that coming a mile away.

 

its lists it under the hood bro

 

Is this hard? I am at 56K, was thinking about going to the dealership due to time being short.

 

B18C is one of the easiest motors to do a valve adjustment. It's easy because you feed the feeler between the cam & rocker rather than the rocker & valve. This makes testing super simple. If the desired size fits, and the next size up does NOT fit, then you're right no.

Head over to Sears and buy yourself this 26-leaf offset feeler gauge:

Just make sure you do it in the correct order and you line the timing marks up on the cam gears correctly for the cylinder your working on. Also be aware your switching back & forth between two different pairs of blades as you go. Don't want to get the settings mixed up between intake & exhaust.

 

not trying to interrupt your thread,i thought this might be a good place to ask..
does anybody know what it means if you CANT loosen a valve anymore?the rocker arm is slammed against the cam lobe and i cant bring it down anymore...any ideas?it's like this on a few of them..



Note: While all valve adjustments must be as accurate as possible, it is better to have the valve adjustment slightly loose rather than too tight. Burned valves may result from overly tight adjustments. Perform the valve adjustment for each cylinder in the same sequence as the firing order: 1-3-4-2.

1) Be sure the engine is cold; cylinder head temperature must be below 100° F (38° C). Overnight cold is best.

2) Remove the cylinder head cover and the upper timing belt cover.

3) Set the No. 1 cylinder to Top Dead Center (TDC). The word UP should appear at the top and the TDC grooves on the pulley should align with the cylinder head surface or the mark on the rear belt cover.

4) Valve clearances are:
B18B1 engine: Intake—0.003-0.005 in. (0.08-0.12mm), Exhaust—0.006-0.008 in. (0.16-0.20mm)
B18C1 and B18C5 Variable Valve Timing and Electronic Lift Control (VTEC) engine: Intake—0.006-0.007 in. (0.15-0.19mm), Exhaust—0.007-0.008 in. (0.17-0.20mm)

5) With the No. 1 cylinder at TDC, adjust the valves of the No. 1 cylinder by performing the following procedures:
Hold the rocker arm against the valve and place the feeler gauge between the rocker arm and the camshaft lobe. There should be a slight drag on the feeler gauge.
If adjustment is required, loosen the valve adjusting the screw locknut.
Turn the adjusting screw to obtain the proper clearance.
Hold the adjusting screw and tighten the locknut(s) to 18 ft. lbs. (25 Nm).
Recheck the clearance.

6) Turn the crankshaft 180 degrees counterclockwise; the cam pulley will turn 90 degrees. With the No. 3 cylinder at TDC, the UP marks should be at the exhaust side. Adjust the valves on the No. 3 cylinder.

7) Turn the crankshaft 180 degrees counterclockwise; the cam pulley will turn 90 degrees. With the No. 4 cylinder at TDC, both UP marks should be at the bottom. Adjust the valves on the No. 4 cylinder.

8) Turn the crankshaft 180 degrees counterclockwise. The No. 2 cylinder will now be on TDC and the UP marks should be at the intake side. Adjust the valves on the No. 2 cylinder.

9) Install the cylinder head cover and upper timing belt cover.

 

Be patient ,i was a bit paranoid like a parrot lol check ,re-check ,check ,again !

 

I would think that means your not on at TDC on the compression stroke. All 4 of the rockers should already be a little loose (wiggle each one) if your at TDC on the compression stroke.

 

Just to add a slight notation to the excellent comments above from 94eg!, make sure your motor is stone cold.

 

but,to my understanding,i am adjusting them while bringing them to tdc..i am making sure the cam lobe that i am adjusting is pointing upwards..
are you saying that i need to rotate the motor again to be on the next stroke?

 

I'm saying you need to make SURE your AT TDC on the compression stroke (not "bringing them up". To do that you need to look at the markings on the cam gears (see below). If your at true TDC on cylinder #1, all 4 rockers on cylinder #1 should have some wiggle to them before you touch anything. Cylinder #1 is the one closest to the timing belt.

If you are 100% sure your at TDC, and your rockers are tight, you have a serious problem.

 

thats EXACTLY the procedure i took to do this..so whats the bad news doc?what does it mean..it is still jammed against the cam lobe..

 

Are you turning the adjusting screw the right way (loosening)?

I can't imagine what's wrong here. recessed valve seat, wrong cam shaft, I have no idea.

 

Ill try to remember to take a picture later tonight and show you what im talking about.
i am loosening it all the way,all the others are fine except for the few that are jammed against cam lobes.
this is b18b cams/valvetrain in a b18a

 

It sounds like your trying to do them all at the same time. You know you can only do one cylinder at a time right? You can't do all 16 at once. After you do the 4 on cylinder #1, you have to spin the crank and move to cylinder #3, then #4 then #2.

 

yes i know,im definitely doing it correctly..
Ill post pics and maybe a video, if that would help more.ill have them up later tonight.

 

Was ur engine running prior to this or you just finish a built and can`t ajust the valves ???

 

i just finished the build and can't adjust some of them..
