Yeah gonna give it a go when i get back from work, that sounds easy enough, how do i go about flushing the engine though?
You may not need to flush the engine????????? The oil may have been changed 7k ago and is looking good. It may well be a mechanical problem simply caused be wear and tear.
Check filter first. If it's covered in sludge as in thick grease then best to drop the oil out, leave it drain all day as it will be cold and will not run out like hot oil, as you are best NOT to fire up the engine for fear of costly damage.
There are many links to flushing engines like flushing fluids and using diesel oil............Do a search and make your own mind up. Personally I would be giving the motor several oil and filter changes over a very short period after a fast run to really warm it up. Of course this is if the engine is quiet????????
If the filter is clean looking it's up to you if you wish to change it and the oil or look at pulling the engine down.
What year is this VE? What engine is in it? How many Kms all up? Do the books show complete and proper servicing at least every twelve months or more often is best?
