oil caps take 1/4 turn to come off

The cap doesn't feel rattley or especially loose when locked on.
But I was a bit surprised when I bought the car at how easy it was to unscrew.
It only requires a gentle turn of about 1/4 turn before it lifts off. This surprised me as my Astra's oil cap needs a few good turns before it comes off.

Are oil caps on these Corsa's all generally like that? :boggle:




Mertin with a good suggestion of degreasing the engine to better identify the leak point. Could you recommend a degreasing product that has proved especially good in the past at removing old oil stains?

I would say your best bet is to get some degreaser and give it a good clean as it all looks pretty dirty and then once its all clean you'll see where its coming from alot better

From the pics, the top of the rocker cover looks stained with oil aswell, are the oil caps prone to leaking on these or is it just spilt oil from a previous top up? Could of been leaking out of there and running down the block to the rocker cover gasket area

I had an oil leak the same on my saxo vts, new rocker cover gasket and then turns out it was coming from the oil cap all along

Thanks for your reply.

So the way that Haynes describes it is how I'm gonna have to do it? Draining the coolant and all that?

I thought the top few covers would just slip off and it'd be a quick and easy job :'(

Taking the top section of the inlet off isn't too bad, the hardest bit is getting to the throttle body. It's also worth getting a can of carb cleaner to give the throttle body and the inlet a good clean out, because they tend to get caked in shit. :thumbs:

Thanks for the advice.
I checked online and a new rocker cover gasket from Vauxhall Parts World is about £8.50 all in.

The job looks simple enough from looking in the Haynes manual - they gave it 1 spanner for easiness.

But Haynes also says you have to remove the upper section of the inlet manifold to get at the rocker cover. Fair enough. But then it goes on to say it's a trickier '3 spanner' job because you have to:
1. install a new throttle body-to-mounting bracket gasket on refitting (whatever that is)
2. you have to partially drain the coolant!
3. withdraw the expansion tank!
4. disconnect the emission control solenoid valve
5. disconnect the manifold vacuum hoses
6. remove the fuel tank vent valve retaining clip
etc. etc.

the job seems to be a lot more involving than at first glance.
Is it really as Haynes describes it??

I've had these oil stains all over the front of my engine and the heatshield for over a year now. The oil level in the engine has remained fine and constant though. I haven't bothered to fix it due to other priority things coming up, but now I have some time.

To my untrained eyes it looks like there is always 'wet'/fresh oil seaping out of a horizontal 'join' in the engine block. But I may be wrong. It may just be accumulating there after running from another spot. I dunno.
What I do know is that when the engine is on you can see oil burning (i'm assuming it's oil!) with light smoke coming from the heatshield area. And you get a stuffy, light burning smell in the car through the vents.

Can any of you guys shed light on what this leak might be?
