When I removed the useless air intake components on my car to drop in the cone,i noticed something very annoying.

The bolts that hold down the valve cover were loose as hell.
I just tightened them equally at about 3/4 turn each.

It could cause some leaks or stupid problems so please guys check that out and tell me if you got that problem too!

 

strange.. i had that same problem... i lost a bolt out of nowhere. took it to a dealership... they gave me a shitty bolt which snapped off the same day. so i had them pull the valve cover and redrill the ****, under warranty. ;D

 

Apparently our cars are not built very "tight" according to a mazda service guy I talked to. But there is no excuse for losing a valve cover bolt because it isn't tight enough!

 

i had that problem too, since i had to tighen them anyway, i pulled my valve cover off and painted it. when i put it back on i did retightn in a circle at 1/4 increments-no torque wrench tho.

 

yes i just started on the lower right, gasket held, it worked out fine.

 

I lost a heatshield bolt

 

so did i!!! WTF! Why doesn't mazda tighten **** when they're assembling it?!!?!?

 

i lost mine too.

 

tightened bolt was an option came with the sunroof abs combo

 

Then I got ripped off, because I got the sunroof, ABS, but no fricken' tightened bolt

 

you let the salesman sell you the "undercoating" didnt you?
