rocker cover engine oil leak
Hi
First time poster here. Not much of a mechanic head but I’m learning as I go!
I have just purchased a 2014 Mokka 1.6L for an absolute bargain of a manager from my workplace - biggest known issue is it has an oil leak. I believe it may be from the rocker cover as it’s only over one side and isn’t severe however I want to sort it out.
I topped up 1L of oil just to drive it to an accessible space for the tow truck to pick up and drop off to my location (so I don’t damage the engine driving it home) due to the leak.
I noticed when I started the engine, after a minute or two I get a very little amount of smoke which smells like burning oil. Is this normal?
Notable things are: head gasket is fine, oil and coolant aren’t creamy whatsoever, as they should be. So I can assume it’s not the gasket?
Also do you think in your professional opinion if I buy a replacement rocker cover with the seal new bolts - will potentially fix the issue before I take it to the garage to get a further look?
Thank you!
