I recently put new type r LMA's in my stock b16a head because they were bad. Now the motor makes a clicking sound, but everything went back together the same way I took it off. The valve adjustment I used was for a gsr and type r, out of the hanes manual .007 intake, .008 exhaust. Any ideas? Do you need to run different clearances on a b20 vtec? I'm also running 11.5:1 pistons.This same noise is why i replaced the LMA's in the first place. Thanks for any help...

 

????

 

No ideas????

 

help help help

 

if its making a clicking sound its lma's or valve's need to be adjusted correctly.

 

Do you know what to adjust them to? Right now there adjusted like a type r. Do you know if b20 vtec is different? In.007 Ex.008???

 

Did you prime the LMA's? Is a random ticking or a consistant ticking?

 

clearances/tolerances are the same

 

what do you mean by prime them? I spun the motor (no plugs) to get oil pres. before I started it . And its a constant ticking 2400-3700rpm's then the motor is too loud too hear, but I think it probably still makes the noise. The motor run fine though, but clicks????

 

he means soak the lma's in oil. just adjust the valves like a b16 -.7,.8 int, i dont remember off the top of my head but if you adjust them perfect and that dont fix it then change the lma's

 

I did soak them in oil for about a day and a half. The new LMA's only have 300 miles on them, and its been making the sound since start up. The LMA's were brand new from honda.

 

any other ideas?

 

11.5:1? im assuming you have forged pistons, could it be piston slap you are hearing? damn, new lma from honda must have been a pretty penny

 

It might be piston slap, but I don't know what would cause it. It came out of nowhere, and yes 8 honda LMA's were not cheep.. Still confused.
I dident change the cam timing or anything like that???

do a compression test to see if the valves did hit you know if your loosen compr, and did you try to adjust the valves? take the v.c off and check and see if there loose.

Ill recheck that stuff, but it was all good last time I checked. Over 200psi comp. and valves adjusted perfect.

 

11.5.1 should be atleast 240 psi in each cylinder

 

My comp. checker only goes up to 200 psi, and it goes past that but i'm not sure what to exactly.

 

well.. i do .006 intake and .007 exhaust. Then once I am done I turn the motor over twice and double check alot of times it changes a few thousands and I have to re adjust them and check again. I suggest you check the clearances again

 

I'll give it a shot. Thanks

 

Valve adjustment is still perfect. Confused and lost????

 

change your oil

 

change your oil and check clearance
