hi would vtec engage right if the lost motion assembly is worn down or put in incorrectly ?

 

Shouldnt make too much of a difference.. How can you put a lma in wrong?

 

it was just a thought so iguess there is something else wrong wit it

 

Check your vtec filter..

 

its clean

 

Whats it doing?

 

seems like its engaging vtec but its not and power dies after 6k power dips way too much on the vtec cross over

 

if you run a cat check it out it could be clogged.

also I ran into a customers car with the same problem, after hours of checking **** out it was a dirty *** intake filter....

check those out first

 

it usually is the simplest ****

check air, fuel, vtec filters. Cat as mentioned. also might bew the valve adjustment. timing is off.


it could be a couple of things
hope this helps

 

If you have a worn LMA you will hear a loud tick, similiar to the sound from incorrect valve lash adjustment. That tick sound should stop upon v-tec. In some cases, but rare, you will only hear a click/clunk upon v-tec engagement/disengagement.

u can put it upside down
i ran into one that took me a very long time to figure out
it the lma was upside down
so vtec will never engage

Speak of the devil.. My car started doing this last night.. Does it kinda sound like a lifter tapping in a v8 engine??

I pulled the valve cover off and pushed the vtec rocker down with a screw driver and it "clicked" back up so im assuming thats what it is..
