rocker cover gasket replacement

Recommended Posts

Hi there, so my rocker/valve cover gasket is leaking and wants replacing. Would this be a big job? Really have no idea. What other gasket should I order for the job? And where is a good place to get gaskets?

 

My thanks

Hello, you need to take the inlet manifold off to do this or at least the upper part of it so you need new gaskets for this too and the throttle body, I would also buy new bolts too if they look corroded.

 

Get the bits from VW to avoids getting parts that don't fit.

Hi,

 

Thought I would use an old thread rather than starting a new one...

 

I'm replacing the rocker cover gasket (plastic covered VR6 one) and just thought I would check something. On the rocker cover there is a small plastic tab on the airbox side of the head that sticks down over the half-moon rubber bung thing that covers the cam hole.

 

Does this tab need to push into the half-moon bung (i.e. pushing it down, which feels too tight), or should it sit next to the half-moon (which doesn't seem to align up very well, pushing the half-moon inwards slightly)?

 

I would go with the latter, but thought someone on here would know for definite!

 

 

Lastly, is using instant-gasket definitely advised, as my old Mk2 golf seemed to leak less without sealant?

 

 

Cheers all,

David

This may seem obvious, but..........

 

The gasket has steel washers in it where it goes over the studs. Make sure that you remove the washers with the old gasket (i.e. don't leave them behind) otherwise the gasket will not seat properly. It shouldn't need any sealant if you carefully clean both machined surfaces. Don't over-tighten the nuts. DO tighten the nuts as you would a cylinder head, that is to say working from the middle outwards and in a progressive way.

 

One or two of the manifold screws will be rather inaccessible and can be quite tight, being steel into aluminium. I found it easier if you release the front engine mounting and jack the engine up a little to give more clearance over the slam panel.

 

If you get new manifold screws from VAG, make sure that you also get new washers; you can't get the washers off of the old screws!

 

Make sure that you stuff rags or paper temporarily into the lower inlet manifold stubs and drape a cloth over the cams and chain whilst working with the cam cover off; you don't want to go dropping bits and pieces down into the bowels of the engine.

 

Best wishes

 

RB

Cheers RB, all helpful. But the studs bit... Isn't that on a metal rocker cover only? Mine has bolts through the rocker cover itself (unless I've misunderstood you).

 

 

As for clearance - thats not problem as the whole front of the car is off :-) (This is part of a head gasket rennovation).

Started dismantling mine today will let know how it goes gaskets Cover, manifold and throttle on order.

 

I fancy cleaning up manifold what about painting and paint type.Should it be heat resistant.

 

Anything I should be looking out for.

Hi Ron - I think you may struggle to source a throttle body gasket - was told these are now obsolete by VW.

 

In terms of the manifold, I had mine media blasted back to bare metal which I think looks great - nice and clean. As yours isn't a daily I'd say you don't necessarily need to consider painting, but a high temperature engine paint such as this would probably be best for some durability: http://www.halfords.com/motoring/paints-body-repair/specialist-decorative-paints/halfords-very-high-temperature-aluminium-paint-300ml

 

Would need to be heat resistant really because of the amount of heat soak from the engine.

 

Might also be worth whipping your injectors out and getting them refurbished? Once the upper manifold is off, it's not a huge amount more work to remove the fuel rail to be honest :)

 

If you decide to replace other nuts and bolts used around the manifold, the covers, etc - all the rest of them seem to be available from VW no problems and not crazy money.

MrInjector can refurbish your set, they'll do before and after flow tests, paint them and provide new seals for around £75 iirc but give them a call. You can get some gasket paper for the throttle body gasket Ron. Just trace out your old one onto the paper then cut it yourself. Easy and cheap to do if you can find somewhere local to buy it and match the thickness of your old one. (Obviously go slightly larger as the old one will have compressed a fair bit over time).

Hi Ron, have been reading through this post. We (JMR) can clean your fuel injectors as we have been providing this service since the days when we used to see you at our workshops. With regard to your can cover we can powder coat this for you and this would be the most durable finish possible. Give us a call, would be good to hear from you

Got to make a decision now do I or don't I get my injectors cleaned while I have my valve cover and manifold off.

VR has done 113k and fuel filter is changed as per maintenance schedule.

Would it make a difference as there is nothing wrong at the moment co and MPG is good.

 

Cheers Jim for advise got paint and it looks good.

After talking to John at JMR injectors were successfully removed tonight and are ready for cleaning.

 

All I need to do now is degrease the area so it is clean for putting back together.

Worth adding a few other bits that they sell too to justify the shipping cost Ron, as they come from Germany. Thats what I did anyway as shipping isn't cheap! They do have some extremely hard to get hold of parts though that simply aren't available in the UK anymore.

Need some advice in process of putting VR back together after removing valve cover to renew gasket. Been given a Victor Reinz one but heard not very good.

Any advice would be welcome.

 

Thanks in advance
