Oil sump change nd gasket help needed

[Ricky180b]

Hi all I'm changing my sump as its got a crack. I've got a new sump but I need advise on the best way to do this and have no more leaks. So far I've been told to get a baffle plate gasket from vauxhall for a c20ne 8 valve engine nd vauxhall sump sealant. Can anyone please shed more light thanks

[Ricky180b]

Also I've been told that if I use the new baffle plate it only has one rubber seal on it. That's all I need no other gaskets butto change the bots to 20 mm. Do I still need to use the sealant and could some please give me te torque number settings for the wrench please

[planetc]

I'd use the sealant, and let it set for 8hrs before putting oil in as that's what we did in the dealers. Can't remember torque figures though, just nipped.

Don't bother with sealant on the 20ne baffle plate pal. Make sure you get shortened bolts

[Ricky180b]

many thanks for the advise. so just to confirm is it just the baffle plate with the rubber seal i need and shorter bolts and no other gaskets.

[Ricky180b]

ive just rang vauxhall for shorter bolts there saying all they do is 30 or 22 or 13. ,

[btcctroy]

22mm I believe

What engine are we talking about? XE? LET? Either way make sure you drop the oil before you begin

[Ricky180b]

Well my engine is a standard gsi cavalier engine

[humbucker]

XE then. Yes the 8v is a single piece baffle/rubber seal whereas the original items for a LET/XE are multi-piece and difficult to line up. I think you have to bend / remove a bit of the 8v baffle though to stop it fouling the pick up pipe.

[btcctroy]

Mine fitted perfectly no need to bend pipes

[gsi pie]

baffle only needs to bent if the xe has a late chunky crank fitted

early light cranks dont hit






both my gsi's have had them fitted both being 20xej's so eraly light cranks
