Valvecover gasket question? + 3 extra questions

[EgonOlsen]

So I removed a valvecover for the first time ever today, just to tell you what level we are on. /ubbthreads/images/graemlins/wink.gif
Good thing I did since it seems a crack in it had been covered with some sealant. Anyway....

it had been sealed using a lot of liquid sealant+ prolly an old gasket, hell of a job to get all that old gasket off.
But do I need to use Liquid sealant as well??
I have a brand new gasket set for the cover + another cover. so I wont need to use the liquid kind as well, do I?

Nope. Put the new gaskets in the grooves on the valve cover, then put the valve cover on the engine. Remember, the bolts are torqued down very little. Tighten them too much and you'll learn why the first cover is cracked.

some people use a little bit of silicone.

There was silicon holding a few spots in my old VC gasket, I just replaced it 2 weeks ago and noticed the silicon. Re-installed a new VC gasket and just left it as is.

 

I like to dab a little bit right where the cam caps meet the cylinder head. I do it for my own peace of mind. I haven't ever done a VC gasket without it. Don't know if it is necessary, but I do it any way

i thin coat all of it with rtv to insure a tight seal. cant hurt to do it IMO. only help.

 

[Terry Posten]

Put a small amount of grey RTV at each place the gasket rises up off of a level plane. And also a small amount where the rubber camshaft half moon plug meets up with the rubber main gasket.

So, small amounts at each corner of the cam cap humps (cam gear end), corners of the CAS hump, and half moon plug.

You should not have to use any to put this gasket on. Some use just a drop to hold the gasket in the cover, but I only use mitsu stuff when using an evo half moon (aluminum).

ok ty, I think that cleared that up. /ubbthreads/images/graemlins/smile.gif

3 other questions then.

I have a spare n/a GTI intake manifold, is that the same/usuable for the VR4?

Can I see easy if the car have upgraded lifters now the valvecover is off?
and last..
Can I see what size the injectors is without having to take them out?(just wanna confirm they are the size I was told)

 

[Terry Posten]

No clue on the intake mani question. We never had the GTI model here.

To tell what lifters you have you will have to pop one rocker off and look at the hole in the tip. If it's about 1mm wide, then they are first gen. If they are about 3mm, then they should be at least 3rd gen.

What color are the injectors? Black, blue, etc... Are you sure they are stock units?

 

[EgonOlsen]

Here is 2 pics of the GTI manifold



And no im pretty sure its not stock injectors, was told it had FIC80, which I think should be 850cc or summat. They are black afaik tell.

Looks identical to the USDM 1g DSM / GVR4 manifold to me.

 

[AWDPower]

On the valve cover, use sealant on the right angle bends on the cam caps and on the half moon seal mentioned above. I really like "The Right Stuff" from Permatex, it seals great and doesn't need to cure...

The Right Stuff

On the injectors, most aftermarket injectors I've seen have the size engraved on the body.

On the intake manifold, make sure it has the nipple for the BOV line. It should be right below the "T" in Multi, I couldn't tell if it was there in your picture.

As stated above it does not have that Vacuum nipple under the T in multi, does that mean its unusuable?

 

[mikus]

usable but you'll miss that port.

As poster said it should be carved on them, probably have to pull 'em to see for sure. My FIC 850's are black with that purple letter sticker.

 

[Terry Posten]

Just drill and tap two fittings into the back end for extra vac sources.

That intake will provide great low end power and still support 350whp as is.
