Ok my car started ticking. The tick is not consitant, hear it , then it stop, rev the car up nothing then back down to idle tick tick tick, ticks but goes away after 2-4 ticks.

Just did a valve lash today, 7 on intake and 8 on exhaust, still does it. Car seems to run better but still have the tick. Not loud like a bent valve but loud enough to notice. Any suggestions?

You probably got a valve sticking. I have heard of burning power steering fluid to cure that.

Hm good idea, But what makes a valve stick?

What engine do you have?
The B16's sometimes have issues with the "lost motion assemblies"

I had to replace mine shortly after I got it running..

B16a, also installed gsr cams 2,000 miles ago, never ticked until recently.

Foreign material in the guide. Some oils are better than others like pennzoil leaves parifin wax in the motor BAD!

Hm dam thats expensive. If my valve is stricking i did put some "mystery marvel oil" in.
i read about it on 10 diff websites people swear by it. So well see.

I think I paid like $140.00 for the set off ebay..
(brand-new ITR units)

LMAs are like little shock absorbers for the VTEC lobe
when it is not engaged..I ran/set the valve lash several times
and it still ticked.. I replaced the LMAs and it has been perfect ever since..

What happens is the spring inside loses it's tensile strength..

mine does the same thing on my b16, its the lost motion assemblies. its been like that for years. I thought it was a vavle job but had it done a couple of times.

Ok so i watch a couple vids, and dam these are my LMA, same place, #1 cylinder by intake mani. ANyways i can change these, just where to get them the cheapest?
ALso When i changed my cams awhile ago, i snapped on of the little bolts for the cam holder, the gold on that supossed to be 7lbs. Where can i get these new, cause im sure the others will snap around 4lbs.

I had the same problem before. I noticed that it happens alot with the auto b16. If your block serial number starts with a 1 it's an auto. I put the skunk2 stage 2 cams in mine and not too long after, the ticking started. It wont damage the motor, but my motor got to the point that it sounded horrible and you can actually hear it from afar. I eventually took it out.
