problem installing pcv blanking plate (bsh)

[cheungy]

Okay got a cheap stage 1 bsh blanking plate today ...

As soon as I got home, I went to work fitting it, it was more or less easy job using a torx screw driver removing the 4 torx screws.

Everything was going fine until the last part where I start to tighten the screws up... the 1 screw on the top left of the blanking plate will not screw on tight and im not sure what happened, however the other 3 on the otherside are fine and held on pretty tight except for the odd 1 on the left (speaking as if you were infront of the pcv plate).

I took a closer inspection and compared the other 3 holes and the 1 thats odd had no core? so as soon as you put screw in nothing will bite on as if its a bit too big? Im guessing all 4 screws are the same size (not checked this yet).

What should I do atm? the car is driving with the 3 held in however it would be nice to get the 4th one in aswell so that the plate is tight and flush.

*a mate of mine told me to use some silicone/adhesive in the hole and then press the screw in wait for it to harden then slowly screw it on tight again?

Did it unscrew ok Dave when you were removing the std PCV?

Anyone else been messing with it? Sounds like it may of stripped.

How about cutting up a plastic rawl plug, push a bit in, then try the screw again?

Don't think silicone will be good enough.

 

[cheungy]

nope its only been removed twice, once to inspect, and twice to remove for the pcv plate.

Its odd, it was biting at first, however it was losing grip quite quickly

I haven't use a rawl plug yet but I mite just try it.

old diy tricks, like rawl plug, match stick (wood bit) ...

 

[Cupra R]

The old ones are the best ;-)

I'll try the rawl plug now let you know just cut shorter right and see if that works?

Mine fitted on ok dude. Sure I still have it too. Can take a look if i go in the loft.

bad news ...although its biting its not closing the gap on the left side so its not fully sealed and when i took it for a blast @wot im getting the flat spots so defin a problem...I'll go search for some garages tomorrow to see if they can retap it prehaps find bigger screws unno

Sorry to hear it didn't work mate, I'm trying to think of something you could maybe fill the hole with and then drill out again, but it's something that has got to allow a very good ite. Because obviously if it isn't sealed 100% it will still cause you problems.

 

[cheungy]

Yea cheers for your advice...

so far the screw is still out however the 3 is holding but its all on the other side (typical).

the best i got it was with the plug you mentioned chopped in half and knock it in to the hole then screw on however it doesn't go all the way in and looses grip again.

Already visited...a garage or 2 and they advice to have it retapped and use a screw one size bigger to secure it.

my car has a service with a local vag specialist next wednesday so I'll leave it until then. It will drive however there is defin leaks @wot (as if its not holding correctly).

I don't want to buy anew valve cover because of this, aleast i hope i don't have too.

Dave, worse case, can you not go straight through, then put a small nut and bolt through?

On a mate's car when fitting his boot spoiler (Clio Cup) the predrilled holes were too big. We cut a rawl plug in half (but length way's, not to shorten it) to fill the hole, then the screws held it in place no problem.

From what I remember the BSH plates hole's are more or less the size of the screw's, so you may have to open the plate out too if going this route.

Wonder if an Epoxy Resin would set hard enough and allow a new hole to be drilled and still give enough for the screw to bite to.

The Rawl Plug was a good suggestion however when you do the screw up the plug slowly comes out which then pushes the plate back out even tho its been chopped the sized and pushed in so that idea won't work out

thought of using the resin too ...wait for it to dry and redrill but need to use the car really no time for the 24hour to cure.

the only idea is for me to take to the garage or service even, then have it retapped and anew screw (1 size bigger to be added)

worst case scenario I'll need to replace the rocker cover for 80 quid

Can't drill all the way as i would be drilling though the cover itself and no end to use the bolt for the screw if it was on top of the plate and not bottom then its a different story (not a bad design just i unno wish it was metal and not plastic.

Sorry if this sounds dim or you've already dismissed it but Araldite Rapid...? The new stuff is spot on.

 

[cheungy]

No I haven't tried that product yet...so just fill the hole up push the screw in, let it cure for like 5-10mins and screw in? only thing, will it be hard enough to hold.

thank you for your advice though - i just want it done asap than waiting until wednesday (service) lol

 

[Sooty torques]

What I'd do is make sure the hole is clean - try to get a bit of petrol in there and clean out any crud, followed by some Meths to be really clean and grease free - then mix up the glue, push it in as deep as you can / get as much as you can in there and then slap a bit of cellotape over the lot to keep it in while it sets. Make sure everything around is covered with rag in case any dribbles out or gets smeared around. Should be able to drill into after 20 - 30 mins or so - even sooner if you need to. Sets in about 5 mins or so, but full strength takes a bit longer - read the packet before you part with any cash.

If the hole contains a rough surface, such as the original thread, it will hold really well.

When the blank plate is off is it 100% flat with nothing sticking out on the face side? When I fitted my catch can plate BSH I cut my connecting pipes as they stuck through and held it off the cam cover.
Although your other fixings are at one side if it's flat it shouldnt bow out on the otherside.
Somethings amiss mate.

I initially thought this too mate, but it's just a blanking plate, it hasn't got the elbow's on that protrude through the plate.

The Araldite could be a winner

 

[cheungy]

Just a update...I have left some Adhesive cure for 24 hours (more or less) but the stuff that cured did not become hard enough for the screw to hold on (wasted effort, though I did use something called "serious stuff" and not the Araldite.

Going to give up now as everytime I am playing around with it the hole is slowly getting bigger and its making the other screws weak aswell. I am hoping my VAG specialist can do something about it on Wednesday, If not I'll just replace the rocket cover with a new one.

*for the time being, I put the old pcv back on as it covers alot more surface than the bsh plate. (happy for now that the car drives.) Very annoyed that this happen to happen

 

[Sooty torques]

Araldite is the one to use tbh - I have used a whole range of glues over the years, but for serious sticking, Araldite is always tops but you have to pay out a few more shekels.

Anyway, sorry it didn't work. Good luck at the garage.

 

[cheungy]

cheers mate

I am dying to go to halfords and try it again, but its likely to make it worst because of me... So i'll leave whats left on the cover and see if the garage can do anything for it. I'll let guys know How I get on.

 

[markgb]

Just a few questions.

1) did you get the sealing issue resolved

2) did you change this because of idling issues

3) how does the car run now

4) do you need the catch can, or is it a stand alone item

Thanks.
