XFlow rocker cover gasket

[dern]

Sorry, another westfield/XFlow related question ...

What do people use as rocker cover gaskets for their XFlow engines? I replaced the squashed rubber one that was leaking a bit with a cork one when I did the valve clearances. If I tighten the bolts up to a reasonable level the gasket moves and causes a leak. If I don't tighten them up quite so much they come undone (happily I haven't lost any and the cover stayed in place... at least my engine won't rust now ). Burton's sell cork and paper gaskets, has anyone had any joy with the paper ones?

Do people use and kind of sealant like hylomar to fix the gasket in place?

The rocker cover is a Burton alloy job so I'll call them on monday but wondered if anyone had any experience of this kind of thing.

Thanks,

Mark

Looks like you're going to have a busy weekend Mark!

When I ran a X-flow with alloy rocker box many years ago I used the standard cork gasket with gasket sealant both sides and can't remember having any problems. Or leaks.

If i remember correctly, Burton's alloy valve train covers used to have a felt gasket.

The cork ones shouldn't be used with those covers as their isn't anything to stop the gasket being squidged as you describe.

Maybe the thick hard card/paper gasket is needed.

Hmm, I have one cork one left (I anticipated doing the valve clearances fairly frequently rather than replacing the gasket on a daily basis) so I'll try that one and then give burton a call on monday and see what they suggest.

Thanks again,

Mark

As an aside I bought some ford cork ones for the 2.9 v6 in my old s3 and that had little metal discs embedded in the cork either side of the bolt hole. You basically tightened down onto those and the gasket was compressed correctly and you have tightened the bolts against something so the bolts don't come lose. It's an excellent idea, can't see why they all aren't like that.

The ford rocker cover for the OHV engines had a metal flange that covered the gasket, this in effect did the same job as the embedded metal pins by stopping it being splayed outwards.

Evening Mark,guess that mail the other day has sprung you into gear!!!!.Don't use the cork one,and when you get the papery sp? one from burtons,then clean the face of the rocker cover with petrol etc and then use a silicon sealant to glue it to the cover.This then allows you the poss of removing it without splitting the gasket when doing the tappets.

Certainly did. I MOT'd the car last weekend and it sailed through with a bit of prep (well, it needs a new track rod end but that's it) so I thought I'd sort out the rest of it now.

Cheers,
