Thread locker or no thread locker added

[pairrothead01]

Folk,

Doing some cooling hose replacements while I have removed most of the intake parts getting to the plugs and ignition coils to replace.

I found while removing all the long bolts of those assemblies ..... there was blue compound on all of them.

I assume it is blue locktite.....but in the FSM, it does not have any reference to applying a thread locking agent.

Advice welcome, I have blue locktite if this is a norm for DIY reinstallation as a prevenative measure for success.

Never noticed any thread locker on Nissan intake bolts. I haven't used it on them either.

While it's apart, check the power valve screws, if you haven't (if it's an automatic).

Thanks for the notice.....inspected the valves and 4 of 6 were loose.

Shouldn’t have any threadlocker on the intake bolts. Definitely do the powervalves though

Power valves done.
Used blue gel locktite

Sorry I didn't take a pick or two....the valve flap, looked as if it had a countersinked hole from the movement.
The screw had flatten threads under the screw head also.
Hope that doesn't comeback to bite me.

Will I see some performance improvement from this fix?

I'm not sure, but I'd be surprised if it gained enough power to notice. I wouldn't worry about the wear so long as the screws still went in all the way and the assembly moves without binding.

All good on bought parts...
Thanks
