is it normal for my car to make a tapping noise after a bc3 cam install.. i asked mechanic to set the valve clearance of .08 and .07 i think.. and he says its good and it just makes that sound because of the cams. it sounds like loose tappets..

 

i used thread locker on the valve tappets after my bc3 cams install. But mines still make a bit of noise also. Running supertech dual valvesprings, i don't know if thats also a reason why they are noisy.

 

my Omni springs and retainers , with blox b's are very loud (compraed to stock)

 

check your lma's

 

Your LMAs are blown. Dont worry about it they are just there to keep your Vtec rocker from bouncing all over the place. They have a little spring in them and when you use a bigger cam it can break the spring. They cost quite a bit to replace and you will just end up wearing them down again. It causes a loud tick that sounds just like a sloppy valve tick. Dont worry though you are not damaging anything at all.

 

alrite thanks guys!! so it wont be anything do to with my valve clearance right? because it would sometimes sound as if my engine was knocking... but it aint.

 

Most of the guys here around town with after market valve train/cams are noticibley loud, I would say its normal

how can you make a statement like that if you havent even heard this guy's engine in person?

abnormally loud vavletrain is NOT normal..no matter how big the cams are...they may be a bit louder than stock..but there should not be any tapping or clanking at all...


pchan:
re-check valve clearance with the engine cold, and check those lma's they can both ruin your engine if not normal..

Please tell me how LMAs being worn can damage your engine?

A lma can bind, what do you think will happen if a cam cant turn when the rest of the engine is?

 

thanks guys! can i check valve clearance with just removing the valve cover? or would i have to remove cams and all?

 

have you never done a valve adjustment?

 

nope never but i am a aircraft mechanic so im pretty sure i can do it with some guidance. lol i guess i'll just a book.

all you need to check the clearance is a feeler gauge set and the ability to set each piston to TDC. If you need to make any adjustments, you can make your own tool.

you'll need a 10mm deep socket, lock wrench, and a flathead. Or you can buy the tool from snap on or ebay. i bought my tool on ebay for 23 dollars.

Are you sure you know what and LMA is? They have nothing to do with the cam turning. They are simply there for the Vtec arm to rest on when the motor is not in vtec. The only problem you would have is if you removed them completly then the rocker arm might bounce around to much and damge your cam.

bc3 spec 111 are set at intake .08 and exhaust is .09 your cam should of came with the spec sheet and ive also called buddy club to confirm the spec sheet that came with it.

oh ok... they have nothing to do with the cam turning?



keep your misinformation to yourself..and keep believing whatever misguidance you have..

 

so just a feeler gauge and not having to remove anything other than the valve cover right? and set each piston to tdc.

 

yup

also, check the lma's by pressing the middle rocker down, if you feel any lma getting stuck upon pressure or a noise at all, i would rec to replace them..

 

It doesnt even come in contact with the cam. Most of the time the LMA is in the up position. When the cam spins it presses the rocker arm down which in turn presses the LMA down a very slight amount. Now with a bigger cam it pushes the LMA more. Sometimes the little spring inside deteriorates and the LMA doesnt return all the way into the up position. So now the rocker arm moves and extra milimeter or 2. How the hell does that have anything to do with the cam spinning. If anything it would spin easier, because the vtec rocker arm is now lowered slightly.

 

ok picture this all a B-series lma is, is a small spring inside of a metal sleeve per say,

what happens when the spring fails in turn binding when the cam is turning??

The midlobe is always in contact with the the mid rocker thus pushing down on the lma when the engine is in motion whether in vtec or not... if the midlobe cannot compress that lma when the whole engine is in motion what do you think is gonna happen to the rest of the engine when that cam cannot turn?

maybe break the cam?

break the t-belt?

valves hitting pistons??

im done argueing with you and spreading my knowledge..if you dont wanna listen thats your own problem..

 

But your wrong. If the LMA fails it just doesnt pop all the way back into the up position therefore the rocker arm isnt in the way of the cam. My LMAs, and about three of my friends LMAs are blown. Its been nearly a year, and I have no problems just ticking. We are all running Buddy Club Spec 4s except one guy running 5s.

 

So are you saying it is common for Buddy Club cams to blow out the LMA's?

dont argue with him, him and his buddies have proved us all wrong already...

 

Not arguing, just wondering why he and his pals keep blowing LMA's with Buddy Club cams. There must be a reason.
