Hey,

I appear to have an oil leak, when my car sits there it seams to leak oil i have cleaned engine up a bit and noticed a big fresh drip of oil around this bolt bear the bottom (see attached pic)

My question is how do i fix it? is it a simple tighten the bolt job? ( didnt want to do it incose the bolt is important)

Or is it the bolt any other possibles?

Cheers,

Mattlav

That bolt is your sump plug, where you drain the old dirty oil out from. It has a copper washer on it to seal between the bolt and the gearbox. If this washer has had it then you will loose a bit of oil. You could try nipping it up a tiny bit tighter to see if it stops it but whatever you do dont overtighten it. If you strip the threads in the box it will be disaster. You are better off getting a new copper washer, they are only about 50p from Minispares.

Hi Matt,

the large bolt in the photo is the oil drain plug (sump plug). If you are sure the oil leak is coming from this bolt, and not from somewhere higher up, i would suggest fitting a new copper sump plug washer. This should be done on every oil service really - have you had it serviced recently? I would not sugest tightening the bolt as the threads can easily be stripped in the sump.

Procedure:

You will need,

24mm socket & bar, torqure wrench for doing it up afterwards

5L of 20W50 oil (MUST BE MINERAL - not semi synthetic - do a search for good oil, but people generally say millers/halfords classic/duckhams / unipart)
New sump plug washer - pence
New oil filter £2-5

Remove bolt.
allow oil to drain
remove copper washer from bolt, fit new one, screw in bolt. Tighted to 25Nm, does not need to be tight.
Remove old oil filter
Fill new filter with new oil, smear a little oil on the rubber seal.
Refit filter.
Refill oil to max on dipstick.
Run engine a few mins to circulate oil, recheck level and top up.

Should take 30mins or less.

Ryan.

Lovely thanks guys.. like i say i noticed an oil leak i cleaned it up and it seams to be very rich with fresh oil around that bolt so i try doing what was instructed and see if it sorts it thanks for you help!

just remember that when you will remove that bolt all the engine oil will come out. so get someothing to collect the oil in

One point added... Saves the bearings a little stress
