Done the sump gasket on the ashtry on Friday, made sure all the surfaces were spotless, followed the Haynes manual to a tee, bolted it all back together, looked fine, took it for a spin, put it back in the air and there was oil pissing out everywhere .
What the sodding hell has gone wrong??!?!
The Haynes manual say's to apply sealant to the gasket which goes between the block and the baffle plate and don't put sealant on the other gasket (baffle plate and sump). Put sealant on the bolt threads and bob's your auntie. Done all this and it's worse then before!!
im doing this next week have no problems fitting a turbo and designing my own mounts to fit f28 into a cav mk2 but i am not looking forward to fitting this sump gasket, are you not suppose to use thgread lock on the bolts im still not sure where the sealent goes vauxhall told me down the sides of the sump but didnt tell me whether sealent is applied on both gaskets or just baffle gasket and is it to be applied on both sides of the gasket.
havent or cant find a torque rachet thats is small and gives 10llb of pressure, ill be usinf a standard rachet are the bolts slightly nipped up.
well i wouldnt expect it to leak straightaway, usually takes a few months for the gaskets to relax and start leaking.
I dont want to be a scare-monger but did you perhaps overtighten the bolts, and crack the sump ? Its very easily done, usually get hairline cracks around the bolt and just below at the angle to the sump. Ive done it once on mine, but that was because one of the dowls had fallen out on assembly and allowed the sump to distort on the tightening sequence.
I bought a second hand perfect sump off of animal, and i have my old one which i had alloy welded up, as a spare. (if you get desperate)
You can actually see it weeping from the gaskets and forming a drip. As I said, we followed the haynes manual EXACTLY and it's worse then before. I'm thinking of putting the sealant on every gasket and every 'contact area'.
I think I will give that ago then. For the moment we have done a super duper bodge job (still leaking though). Basically put sealant round the whole of the sump gasket area. It ain't pretty but it's holding up for now. I've ordered new gasket's and whatnot already
Try using the gasket/baffle part intended for a 2.0 16V Ecotec, the rubber gasket is pre-bonded to both sides of the baffle and is thinner to prevent shrinkage, this worked on mine, the only precaution was to add a washer to the bolts to stop them botteming out, oh and the obligtory clean flange face.
Right I need to do my sump at the weekend, and went to vaux to get the RTV stuff, and thought i would ask the techincian how they did the sumps, especially 20xe ones, he basically said that he recommends that you put the RTV round the oil pump end and NO WHERE ELSE. In other words leave it dry, so i will try that and report back
no, the swines have kicked me out. more important people to patch up obviously, gotta go back tommorow. wouldnt be so bad, but they never gave me any codeine or anything. Bastids, dont pay my national insurance for nuthing.
