I have a 1st gen b16a and it does slightly tick, although the problem your describing seems a bit out of the norm. My friend had an identical setup, but his head ticked liked crazy, and I'm talkin loud. I can't offer any real good advice on what to do, but it seems like a normal thing that can happen from time to time, but I did hear someone mention lost motion assemblies once on here in another thread. OH, but don't use anything less than premium fuel(91 or higher) if your engine is jdm. That's what's recommended for our engines, and that's what u should use, and actually, I read that 95 octane is what's recommended for jdm b16as. For some cars that require premium, anything less can cause engine knocking, pinging and ticking, so that could definitely be your problem.
To check your CEL code, look under your passenger side carpet at the window on the ecu. The red led should be blinking. Post up the pattern and I'll tell u what the code indicates.

 

So there is s red LED on the ECU? Ok... I will post it up after work. Thanks man.

P.S. What is a Lost motion Assembly? -- EDIT

NEVERMIND, I looked it up...

 

I got 2 different codes : Long Long, Short Short Short
That would be (23.) = Knock Sensor - Defective circuit or unplugged / Defective sensor.
Right?

And : Short Short (2.) = Oxygen sensor "B" - Defective circiut or unplugged/ Defective sensor.
Right?

Well, the Oxygen sensor "B", is prob not hooked up, I have a header, and I only have one oxygen sensor in the header (under the car at the end of the collector). I take it, that would be (the A sensor?)

Is the B oxygen sensor a 2 wire green plug? If it is, then I know where the plug is.

So that would be why I have that code correct?

As far as the knock sensor, where is that located? So I can check to see if it is even hooked up..

Also, would this clicking cause it to read as knocking?

 

What ECU are you using? I thought OBD1 B16a's only were supposed to have one oxygen sensor? Figure that out first.

I get that knock code once in awhile, I just ignore it. I just make sure to run good 93 gas, like Shell which is top tier, I've only got it once since I switched to Shell a few months ago and I used to get it a lot more. I wouldn't worry about it too much unless it is constantly coming on.

As for the ticking, I think this is normal. I can hear mine tick pretty noticeably coming through the air vent left of the steering wheel. I adjusted my valves a while back, and this made it a little quieter. As far as I can tell it's normal and the engine runs fine. I think it's just the way they are.

 

Check your other thread. It is your lost motion assemblies. Common problem with B16s...especially 1st gen.

 

Thanks, I have heard 1st gen B16A'z and the clicking I heard is not like mine.. mine is much louder, and its random, not constant with the rpms...

 

1st gen b16as have 2 sensors, both are in the exhaust header.

 

k thanks

 

I know that, ours are OBD0. I was wondering which whether he updated to OBD1 or not because otherwise he would need 2 in the manifold. OBD1 is one in the manifold.

 

How can I tell what I have? its a JDM swap, does that matter? I dont know much about this car or the engine yet, still learning...
