Best gasket sealer?
Discussion
I'm utterly fed up to the f
king back teeth of resealing my rockercover on my PD130 (Bora) just for it to fail again leaving a stream of oil down my street and oil fumes being pumped into the cab!
I want to seal it up once and for all so was wondering what is the best Gasket sealant out there? All i have tried so far are Hlafrauds special shyte and it just keeps failing!
Cheers Guys

you need to work out why the gasket keeps failing
is it because you car clamping it down to hard ?
the surfaces are out ?
not normal for gaskets to keep failing for no reason
I guess you cold weld it all up ??
Apparently it's a common fault that the top right hand corner (front on) of the rocker cover gasket fails. I think its something to do with the arrangement of the bolts (being sis it because you car clamping it down to hard ?

t) that contributes to this. I want to go down the route of sealing it up first as Volkswagen want £120 + Vodka for a new rocker cover plus the gasket!! They don't/won't sell them seperatley! Barrrrstuds!

VW do a sealant for some of their sumps that don't use a gasket, it's about the only thing we've found that works on them. It's best to leave it 24hours or so after using it to make sure it's cured properly. Not cheap but it seems to work.
Thanks I might give this ago.. seriosuly pissing me off now! You think you've done it then you see the rainbow stream of oil running down the road and just want to take a sledge hammer to the fking thing!
hylomar for me every time - and I used to have an Imp engined car so I know a bit about gaskets.... http://www.ready2race.co.uk/shop/shop.php?action=f...
Surely there must be an after-market gasketout there even if VW won't sell one - otherwise it might pay to look at cutting your own out. If the gasket has failed, the oil will find the weak spot.

I wouldn't like to try cutting my own out:Surely there must be an after-market gasketout there even if VW won't sell one - otherwise it might pay to look at cutting your own out. If the gasket has failed, the oil will find the weak spot.
The gasket looks like an upside down T as a cross section and is rubber...
There are aftermarket ones, but as per usual aftermarket products, they don't offer a 100% fit which is a pain...
I have bought some Locktite so will give that a go. I'll take everything off and degrease, clean and seal it all up an give it a go...
When you apply the sealant don't clamp down the cover straight away, it just squeezes the sealant out. Put the cover on the engine with a couple of bolts screwed in just enough to ensures it's aligned correctly, push it down enough to ensure there is a continuous bead of sealant all the way around and then wait for the sealer to cure for a couple of hours before tightening it down properly.
Also, give the rubber gasket a good going over with a solvent (e.g. brake cleaner) to remove all traces of oil and if the rubber has a very hard, shiny surface, try removing it with e.g. scotchbrite pad, or a carefully applied knife edge used as a scraper. This removes the hardened material at the surface and exposes fresh, softer rubber.

Best not to use a silicon on engines... Unless you are very careful it squeezes out inside the engine, goes hard, becomes detached and then blocks things up... I have seen so many bike engines damaged by this
Loctite do an anaerobic sealant made for the job, give it a try, it's never failed for me yet. It dries when air is excluded, so any that squeezes inside the engine is washed off into the oil and does no harm

Hi, new to this forum so forgive me if I only open my mouth to change feet. Read all the comments above while looking for answers to a similar problem. I have a Passat tdi pd 100 with the same issues. After a mild cardiac arrest when vw asked for £130 + the usual (sorry, you haver to buy the cover as well), the parts guy took pity on me and directed me to GSF. They supplied a gasket only for £10.74 inc VAT. There is a warning that there are some "older" covers may not be compatible, so I have to keep everything crossed until it stops raining long enough to check, but thought this might help someone else. FYI the gasket is made by Victor Reinz. Will post results later, if not, going with Hylomar Blue as have stuck many bike bits back together with it!

Holy thread ressurection batman!!Been a long time since I had this issue. And, unfortunatley, I had to succumb to the £120 cost of a new rocker cover and gasket kit from VW.
Was a good job though, upon closer inspection, my old rocker cover had actually warped which never gave it a good enough seal!
For the amount of money I speant on oil and sealant, I would recomment sucking it up and buying a new kit from VW. It makes sense in the long run!
Oh, and welcome to PH!
