This may be a stupid question but, I have a Westfield V8 (4ltr range rover block) which started leaking oil somewhere towards the front following an oil change. It has a Mocal remote filter. The leak is bad enough to need attention so I'm going to take the front off to gain access, the stupid questions are, why following an oil change? and are there any "usual suspects" for leak points? as its all a bit mucky at the moment its hard to see where the leak(s) may be but I'd guess at right at the front and possibly something to do with the remote filter. Any pointers before I get the front off will be gratefully received.
