cold-start piston slap or you need an oil change. mine does it too after 2500ish miles.

for a new car, i also found my ms to have alot of valvetrain noise on startup, but its the same as ever other 2.0fs ive heard. synthetic oil of course. maybe because you changed the cams, the effect is more audible than with the stock grind.

i have some valve tick as well

Have you measured valve lash with the new cams. The FS motor uses a pill/solid lifter design. Mazda makes a few different sized pills.

you can have a machine shop shim it for you for around 100 a cam at a good shop.

you can do it yourself,If my mind is working correctly,I think there should be around
.022 gap between the cam and bucket.make sure the valves are closed for that cylinder when measuring..

I can tell you tomarrow if no one else does first.

stock lash is .010 +- .001 Of course that is with stock cams, I don't know if its the same for the JDM ones.

 

[wicked]

I think it will be safe with the same lash,I doubt they will bind

 

[DonSVO]

you definitely need to make sure that you are adjusted correctly for lash. they sell different buckets *sit on top of the valve & spring* so that you can correctly adjust the lash.

 

[Paul]

i am so confused right now.

 

[wicked]

It's not hard to understand,but if you really need help,you can take it to a machine shop,or even mazda.
were do you live?

it's not the buckets you would need to buy,they have shimming pills in the top of the buckets,they come out with a fine flatheat,and a magnet.

 

[Paul]

why would i need to get this done?

 

[wicked]

so your valves fully open and close,and you don't cuase unecasser ware on your valvetrain
