Hi all,

Sorry for posting this rather than finding in a search - but for some reason search function isn't working for me.

I have an oil leak on 2004 VXT that turns out to be coming from a rusty scab on the sump oil pan. Can anyone direct me to where I can buy a replacement pan?

Cheers

Kev

Replaced mine about a year ago. I paid about £130 Inc VAT back then but they seem to be north of £200 now. http://www.vauxhall-..._-_9158192.html http://www.genuinepa...tnumber=9158192

Just checked. I paid £151 from Autovaux using a 10 percent black Friday discount. You'll also need a new gasket at about £20.

Gasket part number is 90502090 https://www.speedste...ings/index.html

Many thanks mate - given up expecting things to be cheap just because they are GM

I presume replacement is as straightforward as it looks? Remove retaining bolts, clean up surfaces, bolt onto new gasket? Or did you use any gasket-seal as well?

I'd like to say yes Kev and I'm sure it is. But I had mine replaced during a service by Matt Bentley.

How about a used part, alot cheaper - http://www.csautos.n...parts-603-p.asp

Good find Dave! They are rare to find without corrosion.

You're a star Dave...many thanks (now ordered). If you ever need an upper sump you know where there's a free one for you 👍

The chap is called Chris, I have met him once - I had a mk4 astra sri turbo  (z20let)   

 

I found him on ebay many years ago,  his best prices are found on his website.

 

He buys a lot of LET / LEH and breaks them for spares

 

 

 

Glad I could help  :-)

Hi Kev, Are you sure its coming from the sump? Its very common for the banjos on the pipework to the filter housing to leak...definitely worth checking 👍

I have used Steve @ Vauxhall turbo spares , Essex for gearbox without problems

Mine was failing exactly like Kev describes. It's a common failure on these sump pans. I have a picture but cant seem to upload it on here and of course photobucket is no longer an option.

Yep...no sign of oil around the sides of the pan and a thick scabby lump of rust on the bottom of the pan that oil is dripping from. Was a surprise to me that such a thing could happen, especially since it is protected from the elements by the undertray. I presume (worryingly) that this is a drop of water sitting inside the pan under the oil that leads to corrosion.

I'll get a picture when I do the swap

It think it happens because small amounts of water moisture can get into the oil. When you switch off, it sinks to the bottom of the sump as it's heavier than the oil. As the water can have contaminants that make it acidic, it has a tendency to erode the steel at the point at which it collects, or wherever there is a scratch or dent maybe.

 

The best thing to do is to try and do longer runs and get the engine/oil hot to try and turn any condensed water back into steam and drive it out. Lots of cold/short drives tend to cause this problem.

avoid a sump from a FWD donor car as they are exposed in the engine bay to all sorts of damage , whereas the VX is protected by the undertray. same goes for the gearbox , you notice they are almost pristine when taken from a VX

[kevster]

Sorry, another question. What is the correct torque for the oil pan bolts and should I use a gasket seal with the gasket? Cheers Kev

[Wolfstone]

http://www.vx220.org...s/?fromsearch=1 Not sure on gasket seal.
