Right last night while in work while just having a quick check of the engine i notice dwhat looked like a oil leak at the bottom of the engine , looks like its the oil sump? ( sump directly behind the plastic drip tray?) so had a closer look and its got a large rust spot / bubble about the size of a £2 coin right at the front and the oil is starting to seep out from the edges of this :'(
So looks like i need a new sump?
How costly are they?
How easy are they to fit?
or....is there a quick fix i could do, maybe some sort of sealant over this rust patch? as im working alot of over time at the moment and might not have time to get it into a garage :'(
I'll leave you guys to ponder this one while i head off to bed and will check the results later :y
-
Get a replacement one from a scrapy.
they should not be that hard to change depending whats under the sump. but normaly its unbolt the old one clean and then replace the gasket and bolt on the new one
-
so hard to find omega parts in scrap yards around here thats the problem, anyone got any ideas what a new one from the dealers would cost?
So there no quick fixes for this problem? no products i could buy to just patch over the hole?
-
Just rung Vauxhall and its £135 for a new sump :o :'( and none of the local scrappies got any, so i guess its the dealers for me. Surely its not normal for sumps to develope rust spots that then split it?
-
I dont think that theres an easy fix for it mate. sounds like a bad spot.
Try and pm one of the breakers on here youll find them on the parts for sale. they could help you out with a replacement.
-
Just taken it to a local garage and they've said that yeah its a bad spot on the sump and its starting to rust through :'( as they are just a small garage though they are worried the engine might need to be lifted out or up to replace the sump , does anyone know if it does? and they arent sure if it has a gasket or it uses sealant?
-
I used some of this ..... http://www.devcon.com/products/products.cfm?marketid=1&familyid=116 on my Senator's petrol tank! It worked brilliantly! Might be worth a try as a temp fix.
I always find it amazing that something holding oil can rust through! :-? :y :y :y
-
cheers :y will give something like that a try as just typical with my luck with cars, when im doing normal hours in work its fine not a problem the second i get overtime! the dam thing breaks! lol im working the next 19!!! nights so dont really have the time to get it into a garage ::)
-
I'd settle for welding a small patch over the hole myself (seam welded obviously).
-
i was thinking a similar thing maybe just weld a patch on it but now in the day light when the guy at the garage had a look its got 4 other rust spots on it , so id just end up constantly having it fixed ::) i agree with a previous poster, how can something that holds just oil rust right through! ::)

By the time you removed it to weld you would have fitted another/new sump ..... unless you're going to weld it with oil in there! :-? :-?
-
Has anyone here replaced or removed the sump before though? the garage said theres a cross member in the way and that needs to come off but like i said they are a bit worried about whether the engine needs to be lifted :question
-

The paint on the outside has come off over time and it's rusted in, from the outside. A deep stone chip will accelerate the rusting through in a particular spot.
If you can wait till your nights finish, just keep checking it, it shouldn't cause any problems unless it's really bad.
I'm sure someone on here will come up with one for you.
-
Its actually not leaking too bad, but im just worried if i hit i bump or something, it will split the sump right open as its obviosuly weak right now and the car will drop its guts all over the road ;D
-
if you,ve a manual it will tell u in their if u have to take engine out or lift up

If it's as small a leak as the OP leads us to believe, then there would be nothing wrong with welding a small plate over the top of the hole while the sump is in situ and filled (unlike the epoxy resin solution, which really needs to be "clean" while it cures).

It's easier to re-apply ythe epoxy putty if need be than put the the fire out in the engine bay after you set fire to it! ;D
-
Right my co-worker last night put some sealant over the hole but im not sure it designed for things like this, as the sump gets very hot and im guessing it will just cause the sealant to come loose ::) but its a quick fix for now till i got the time to get it sorted.
Haynes never did a manual for the Omega did they? i got told that the 2.2 from the vectra is the same engine and you can use the manual for them on the omega, is that right? :question
-
yes haynes did do a manual for the omega goes upto a t reg 1999 but the mechanics are more or less the same
-
mines a 2004 though :( so the omega manuals wont apply to mine
-
as said the mechanical bits are more or less the same throughout from 1994-2004

Try these UK spare parts locator sites.

cheers :y will give them a look
-
IIRC the sump is in 2 parts, if its the part with the sump plug i'm sure you can remove it with the engine in situ
-
Yeah i think its the part of the sump with the plug , the rust spot it right at the front of the sump, i think the garage yesturday said the sump is in 2 pieces the front streel and the back aluminium.
-
you might want to try this (quicksteel) another epoxy putty

Right im just on my way to halfords to buy some of this epoxy putty that you guys have recommended as a tempory fix for the sump leak, but while on their site i was treatments for rust , i was just wondering do you think this stuff would be worth adding first before the putty? just to help seal up the hole :question
-
heres the product i was thinking of getting

I would'nt bother with that for a temp fix - it may get you an extra month or so - no idea
you have a few rust spots on the sump but it does not mean you need to replace it. the spot that is leaking, it is on a flat part of the sump? If so I'd suggest a good, drop the sum as best you can and fit a bolt through two flat washers, one inside and one out. tighten up and you are there. As to the others, i'd clean down to bare metal, then pain with primer, then two coats of hammerite paint who cares what it looks like if it doesn't leak!
-
the rust spot from where the oil was leaking is on the flat part of the sump right underneath, and its about the size of a £2 coin so pretty big, ive actually put the putty on now and so far so good no drips, no leaks, so as a temp fix its looking promising :y but say i decided to leave it as it is with the putty on the sump covering the leaky rust patch and i had an MOT done....would it fail on the MOT due to this quick fix patch on the sump :question
