Hey About to change the sump on the mk2 whats the better gasket to use ? Paper Cork or Rubber ? Cheers
if you get a rubber gasket you need longer bolts, I'd just use the cork gasket if staying std. you could get a windage tray from a diesel mk3 if you felt like it, but again need longer bolts
With cork and paper gaskets I like to warm up the engine after and then let it go cold again and retorque the bolts. Theory being as the engine warms, metal expands and crushes the gasket a bit more. Then it contracts when cold leaving the gasket slightly "loose"
The thick card/paper type every time, OE spec on earlier vehicles. Also look at using “weldseal” works a treat on paper etc, never ever leak. Cork splits if over tightened, rubber only with windage tray or with ally inserts to stop the rubber being squashed too far and pushing it out of the side
actually that being said i think i used a paper one on my MK2, basically whatever GSF supply. I just nipped the bolts up and never had a problem.
the vw one i got for mine was rubber and only cost a tenner or so. 10nm on those little bolts and thats been fine since
yeah yours is an abf so it has the right length bolts already, if your car has a cork/paper on from zee factory you need longer bolts
high tensile m6x20 socket head bolts from screwfix = 2.31 inc vat for 50pack toffee m6x17 hex head bolts from vw = approx 70p + vat each and you need 20 if you go with the rubber/windage option just use the new m6x20's as they fit fine although 2 will need a washer behind them. will be obvious when you fit them which they are.
tip of the day: do the 3 bolts at each end of the engine last as they go into ally plates and if you do them first there's a good chance you will pull out the threads. not that I just did it of course...
Hi folks, sump gasket was leaking, have got rubber gasket and slightly longer bolts N90592703, question is do you need sealant for rubber gasket, I was thinking not but just making sure
I used some sealant only on the space between end seal flanges and block. Even if they are rubber if used again will leak. Happened to me on valve cover and sump. I read some do not use any gasket just sealant, i believe this works, i have seen on cars from factory, vauxhall combo c for example.
That's common on newer stuff, as the surfaces are more rigid and machined more precisely. The sump on a mk2 is far too flexible though.
Well it's fitted anyways, used a little sealer with gasket as suggested, was straight forward as gearbox out☺️cheers for replies
