okay, honda-techies....here's my set up...i have a del sol vtec...the motor is a b16a3...there is a loud ticking coming from the motor right above cylinder four where the intake rocker arms are at...i already did a valve adjustment at Honda with no help...i bought a new distributor and the noise is still there...i've been told that it could be the lost motion sensors, bent valves or carbon build up on the valves...any suggestions or help?....all inputs are appreciated...thanks...

do a compression check to see if your valves are messed up. thats a good start!

buy a new set of LMA that happend 2 me.

by the way the b16's are known to get that ticking noise, the culprit i believe was the LMA, it was the problem my cuzn had in his b16

I would deffinitely assume valves or rocker arms tapping/out of adjustment.

LMA=?.....btw, thanks for input everyone...

Wow, am I glad I read down further before posting...

My 96 Del Sol VTEC has this SAME exact issue. My friend says "rocker arms" but he is not for sure. I almost paid a $50 diagnostics fee to find out what this annoying problem is.

BTW what is LMA?


Thanks!

hey what a coincidence...my 94 Del Sol VTEC makes the same noise as you guys, on the Cyl 4 as well. What is an LMA anyways?

orientalgunz_00

i found a link to the lma...this was what i thought was called the lost motion sensor, but i guess i was a little off....here's a link to what it looks like and where it's located guys, just so you know...

Thats great, and I found this

maybe it will help more?

Also, if the LMA's are bad, what does that mean will happen? Like is it going to throw a rod any time soon? As you can tell I'm a noob when it comes to mechanics but I really dont want to be driving my car too much if is about to die. I just bought it!

Probably just injector noise.

orientalgunz_00

haha, injector noises shouldn't be this loud...plus i think it is the LMAs...which actually stands for Lost Motion Assembly....i'll try this and let ya'll know...thanks for the help everyone...

lmas are quite loud
test them

Where is a good place to buy some LMA's and what kind of job are we looking at here? Dropping the engine, tranny, how many hours?

orientalgunz_00

you can get them at hondaautomotiveparts.com or at any dealership...they sometimes come up for sale on this site too...no, you don't need to drop the engine...as far as i know, you just need to remove distributor, vtec solenoid and cam gears so you can pull out the rocker arms...then you just pull out the lma...do a search...plenty of info on lma...

who-got-rice

how many miles on your motor? wanna laugh i picked up a car that one of the cams was rubbing on an inside piece of timing cover clicked pretty good as it turned, couldn't see it, very deceptive sounding as far as where it was coming from, i thought it was the dizzy, also picked up a honda that had a water pump that was loud and had a clicking sound, b and h series are pretty tough and over all don't have tons of lma issues
