Hello familyguy and a very warm welcome to the forums.
First up the
leak could very well be coming from the sump plug. It is a small worry in as much as it's not going to get any better. Also could be coming from the
filter housing. I think I have read on the forum about the filter working loose. Also could be the dip stick tube. At the bottom of the tube is a rubber seal that goes hard with age. Easy to replace, just unbolt the tube and pull out. replace the rubber seal and refit. Best thing to do is park the car over a clean piece of paper one evening and check were the
is leaking on the paper. this will give you a better clue.
Not too sure about the vibration you describe, may be a little bit more info?
Tyre pressures are:
Wheel size: Tyre size Front Rear
6 x 15 185/60 R15 33lb 33lb
6 x 15 185/65 R15 T 33lb 33lb
6 x 15 195/60 R15 33lb 33lb
6.5 x 15 215/65 R16 T 29lb 29lb
As for the engine
I would recomend giving your local Renault dealer a quick ring. Renault seem to change their idea about
on a regular basis.
Hope this helps. kind regards Oilyrag.
