Hi guys, Have I to use Loctite 5900 for nuts and for the gaskets to? So i have to put I line of glue and put the valve cover later? And I have to do the same for chain tensioner one or is not necesary for that one?

Regards and thanks.

If you are talking about the valve cover gaskets, and you've got the factory ones, you don't need any goo. Clean the valve cover channels and the mating surfaces on the head very carefully... and check your valve covers to ensure they are as flat/true as possible. That's important.

Also you only need to tighten the nuts to 7 ft. lbs. That's only wrist-tight...not much at all.

Just make sure you've used some means of nut retention. (Insert punchline, here.)
7 ft-lbs isn't much to keep a nut from rattling off in a high vibration environment. That's purely my opinion.

If the nut has some anti-backing feature (eg. a 'nyloc' nut) that's fine.
For a free-spinning nut, I'd recommend a little dab of blue loctite.

Otherwise, I've never used anything other than the valve cover gasket to achieve a leak-free seal.

I am pretty sure the valve cover kit comes with fresh nyloc nuts no?

You are correct.

The kit I got from PP had what I call "crush nuts", but I guess the actual term is "distorted thread lock nut". Anyway, I think they are better for this application because the locking of the nut is not affected by heat or oil, which can make Nyloc nuts less effective.

Pelican sent me a kit (2-3 years ago) with plain, spin-on nuts.

Talked to them and they credited me the cost of nylocs I purchased down at my nearby Lowes nut bin.

Subsequently I buy my own 'kit' components separately.
Bought a box of 100 squeezed nuts (as shown above) for around $10 from McMaster Carr.

(This DIY stuff can become addictive!)

I bought the original nuts.. so what could I do? some loctite?

Ken D

The original Porsche nuts are locking nuts - so you should be all set.

The nuts I've purchased from Pelican have always been nylocks.
