ok so i really need help here my current situation is i have a b18c (type r) block with a 90' b16a head and I'm using type r cams also. I assembled everything correctly tightened everything in sequence and correct torque specs. the head is still off the block btw i turned both cams to tdc both marks on the gears lining up and arrows facing straight up also but when i look at the under side there are some valves that are not seating correctly in cylinders 2 and 3. Im confused as to what is the problem is I've read other posts that said itr cams in stock b16 head is great and should be no problems. Did i do something wrong assembling everything? Do i have a head with already bent valves? Do the cams need to be installed a certain way? Do the valves just need to be adjusted? They are type r cams with adjustable cam gears, do the adjustable cam gears make a difference?Any help would be awesome thanks!

 

You did identify the intake and exhaust cam's correctly right? You did zero out the cam gears right?

 

Yes intake and exhaust are correct but about the zeroing out I don't know what that is. I hope nothing is messed up if I have to take it back apart to zero out the cams I will this is why I made he post of there was a step I missed or somthing I did wrong, whatever help I can get is great

 

Have you already set your valve lash to spec?

 

No, what is valve lash?

 

Find stock b-series vtec cam gears and don't use the adjustables until you know what you're doing with them.

 

Basically it's the clearance between the cam lobe and rocker arm. It is possible to adjust them with "negative" clearance which will result in the valves starting in an open position and never actually seating or closing.

 

Wait...you have the cams in the head.

And your asking about why some valves are open???

 

lol

bro just take the head to a shop have them inspect it! then when you confirm the head is good then put it on the block and assemble the engine.


But the fact that you don't even know what the valve lash is just drop all the tools you have take a step back and sit on the computer and search then search some more and when you think you have an idea on how to build the engine search some more before you go and attempt to do something you have no clue on how to do. This is how people **** there engines up and then make a silly post here on why the engine blew. Building a engine is not like building legos!

 

I don't need anyone's "bashing" negative bulls*** Alls I said was I need some help as to what my situation is.. I bought a b16a head and Installing itr cams, this is not an unheard of setup. The cams already had the adjustable gears on them (which I don't care to use) I would like to know HOW you "zero" them out or how do i set them to where it's like stock cam gears bc I don't have stock cam gears at the moment. So again can I have some actual help please, if anyone knows. From my understanding the problem is adjusting these cam gears correctly bc installing type r cams in a stock b16a head has been done countless times with no problems it's the same cast

 

Your getting bashed cause your asking to be spoof fed info that you can just research your self or by reading a manual instead you want to skip out all the hard work many do themselves and want to get your answers, well this forum don't like that! lazy people get no where in life!

Ill be nice and tell you your issue isn't with the cams or cam gears.

If your stuck thinking you have bent valves pull out the cams, flip the head on its side and spray a good amount of brake parts cleaner in each cylinder port and let it fill up and watch the valves on the bottom of the head for leaks, if no fluid seeps out then the valves are not bent.

When you set the cams in whether its after market cam gears or stock, if its aftermarket gears make sure the middle line is at 0 which means its not retared or advanced. you must line up the two arrows pointing up and the middle lines on the cams should line up as well, once this is set the cams are at TDC then confirm the crank is at TDC and install the timing belt and go from there.



Stock gears set at TDC,







Aftermarket gears set at TDC,,

 

As you can see they are both set at TDC I never touched them this is how they were already set but no1 can seem to tell me why the valves are sticking out in cylinder 2 an 3 I've researched enough and can't find answers from you or anyone appearantly I've done timing I know what stock gears and tdc all is. And I did also do the brake clean test there is no bubbles coming out

 

Look for the fluid to seep out not bubble, it should leak out around the valve face if its bent. The cams should open the valves in 2 cylinders cause the cams are torqued down in the head. When the cams are out the valve should all be closed.


B Series Valve Adjustment

 

Ok I will try the brake clean test again but When the cams were out of the head all the valves were closed just fine only when I installed everything is when they popped out alittle just like you said in your last post here is a pic of what it looks like now (with the cams set to tdc)

 

If the cams are installed in the cylinder head, and the cam caps are properly torqued down, there will ALWAYS be a time when one or more cylinders have valves open. If you look at the cams and rocker arm pads above where the valves are open, you should see the high point of the cam lobes on that cylinder facing down toward the rocker arms. If you remove the cams, and you still have valves open... then you have a problem.

What you are showing us could very well be normal.
