Hey guys I recently put a ZC SOHC NON Vtec Camshaft in a 88 D15B head, and I adjusted the valve lash according to what the head is required. The valves are loud, more then they should be. My friend told me they are loose, or not at the right spec. I was wondering if anyone knows the correct Valve lash adjustment for this? Much help greatly appreciated. Thanks...

 

intakes - 0.007 in.
exhaust - 0.009 in.

 

Is that + or -? because under my hood it says intake 0.25 and exaust 0.20 or vice versa IDK. Also Im using the original cam gear not ZC or SI. Thanks for the reply..

 

Well any more ideas?

 

You do know thats in millimetres?

 

Ok well in millimeters, how much is -- "intakes - 0.007 in.
exhaust - 0.009 in. ??? Thanks

 

.007" = .1778mm
.009" = .2286mm

Do you not know how to do math?

 

Obviously not like you, I hate fractions and sh^t Don't Critasize lol did I spell that right? probably not. lol but thanks for the information. I just don't want to fu*k **** up right now. But to ask one ? without negative statements, what do I set my feeler gauge to? The head is normally adjusted with a .20 gauge for one side and a .20g and .5g with the other. In=.25 Ex=.20 So what would it be for a ZC SOHC NONVTEC CAMSHAFT IN A D15B HEAD????????? I doubt they make a .1778 or a .2286 feeler gauge. So please,, Sum it down for me Thanks again LMFAO

 

No real fractions are involved and you can easily use a calculator... Your computer of phone has one built in...

We know 1 inch = 25.4mm

So to get mm from inches you:

inches X 25.4 (inches multiplied by 25.4)

To get inches from mm you:

mm / 25.4 (mm divided by 25.4)

I am not sure what you are asking??? First off what set of feeler gauges do you have? Standard or Metric?

 

Well regardless - like I said before...


.007" = .1778mm
.009" = .2286mm

So use a .18mm on the intake side and a .23mm on the exhaust side... set the valve lash cold. Also - the cam gear, camshaft, ect doesn't change the valve lash on Honda engines...

 

I need to adjust the valves so the camshaft lobes aren't ticking like they are. I don't have the stock camshaft remember, I think they are metric. But I just googled it and it said something like the CRX has the same Lash adjustment as what jlicrx posted. 0.007/0.009. .so did the CRX's have the SOHC ZC?

 

In non-USDM CRX's... you need to lay off the pipe kid.

 

Seriously that's all you got? no more specs? K TTYL Nevagetsatasfide lol

 

What are you even talking about? I broke it down for you and everything... Your engine is essentially a D16A6 with a slightly better camshaft - it still has absolutely NOTHING to do with setting the valve lash. The SOHC's have their numbers and the DOHC's have their own... What more information are you wanting? I can't hold your hand through the Internet.

 

I just want to throw this out there - is the head code relevant at all (ie PM3 or PM9 etc)? I know civicboy420 and took a look at his head and block the other day... Would valve springs/seals cause the ticking due to the ZC cams longer lift & duration?

Thanks in advance I am new to Honda-Tech, my ride is 91 Sedan ED3 with D15b2.

 

The difference is MINIMAL... so No. When I say minimal I am talking a few thousandths. Just for your information - duration has nothing to do with needing different valve springs or not. If you were bottoming out the springs you would either have already destroyed the top-end/ it wouldn't even run/turn over to begin with.

 

Yo Yo What up ED3 How's the car running? Mine? Still loud under the hood lol. Wish I could get rid of the ticking.. Anyone care to help? LMFAO And No Neversatisfied, I don't role that way. It's cool if you do, I'm not going to judge. And how is my motor the same as a D16a6? It's a 1.5L not 1.6. How hard is it for you to get that the ZC Camshaft has bigger lobes. It's not a 1.5L Cam! **** man. But Nate, I put a white cloth in front of my exaust and it was black within a few seconds. I just don't understand because my FN block is still good and I have a rebuilt head. I'm ready to just throw a D16Z6 head on there and call it good. People think there FN Geniuses on here lol I appreciate all the help I get, but from now on if you can't help without coming up with some lame derogatory statements, please stay away from my postings. Thanks again! Peace ED3

 

just get a proper set of feeler gauges that includes the .007 and .009 gauges...this set should include every gauge you'll ever need to adjust any civic.

 

Wow... you never said it was a 1.5 engine - just cylinder head. Obviously I assumed you have something done. I gave you all the information you requested - clearly you are ignorant. You can't use math to convert, you can't add feeler gauges to get what you need, and you can't adjust the valve lash properly...

How can you not understand that on a Honda the lobes can be whatever size you want - but you can NOT change the base circle. It's not like a V8 where you can run a small base circle camshaft for clearance on a stroker... The fact you bring up cam lobes for setting lash has literally made me bust out laughing. Do you not realize you set the lash on the base circle and not on the lobe? I know so much it would make your head spin... yes I am full of myself. Either way, I don't take any of this personal - why are you?

 

Im going to try and get ahold of a compression tester to get some numbers on my ride and we can run it on yours too (for the rings)... Rings could be the cause of that soot out the back, and low MPG too... The valve noise is weird, and Ide be interested to hear what improvements adjusting makes. Process of elimination LoL... Keep me posted brotha man

 

civicboy...as much as i hate to agree with nevaeva, and i do....the lobes have absolutely nothing to do with lash, you adjust the valve stems when the valves are CLOSED...not open, if you did adjust them while open your motor would be all out of whack because you can't have a gap on what's pushing the valves open, if there's a gap, the valve isn't open, try turning the adjustment screw while the lobe is pushing up on the stem, the valve will start to close..it'll take a .007 and .009 feeler gauge. there's plenty of how to's on how to adjust valve lash, it isn't a complicated procedure, and imo, more common sense than anything, the only thing you should need to know is what the tolerance needs to be, and now you know....

 

Thanks BIGD4207 I will do that. Now let me start over, I have a ZC SOHC camshaft in a D15B motor. Block is D15B and the head is a PM3 D15B2, I was told the ZC shaft is more aggressive. I haven't seen this "Aggressive" since I put the ZC in. Just loud valves. I know the shaft is in good shape, took it to a machine shop for them to look at. I just don't understand when you guys say all SOHC motors have the same valve lash, and the DOHC has there own. I'm really happy I got you laughing, you act so ****ing serious on this website, Math? LMAO i told you about that.. lol. And I do know how to adjust the valves, That's why my car is running right now obviously DUH! I was told that you adjust them differently when you add a ZC Camshaft to a D15B head. And who said anything about cam lobe setting? I was talking about adjusting valve's LMFAO. We can argue all day about this ****, and I don't care how much you know, I didn't ask for YOUR help. Anyways, Thanks everyone for all the help, hopefully one day I can figure this ticking **** out. @ED3, I cleaned the MAP and O2 sensor and it's not blowing out the Soot anymore, so I'm sure I can pass emissions now. Thanks again.

 

Thanks BIGD4207, my dad was down to rebuild the whole motor, HE has like 40+ years expeirence, and as we got to the head, we adjusted the valves occording to what under the hood says. And everything works fine. It obviously is because the car is running. Just everyone I talk to says my valves are really loud(sounds like a diesal). My last civic I had purred like a kitten. Anyways thanks again for your help.

 

Are you adjusting them in order? 1,3,4,2?

What cam gear are you using?

I cant remember if the cam timing is different between the two.

If so say there is a timing difference and say if you are using the wrong gear and say you are adjusting them in order,...its possible that your adjusting valves that are compressed by the start of the cam duration. If this is happening even though youre adjusting them in order to the proper lash it will be off because of incorrect mechanical timing.

One way you tell tell if there is a difference between cam gears is put them up to each other and see the difference. I do know for a fact the there is a different of almost one tooth between B2 and B7s

I'm just saying its a possibility that hasn't been looked at.

 

Yes I did them in the correct order. I'm using the stock cam gear. I was told the D16A6 and D15B,B1/2 have the same one. Also the head I got the shaft from was a ZC head, and I'm using that cam gear. Same as my old D15b. Thanks for the help man.. Much appreciated.
