After giving the cossie a hard time for two nights in a row the dreaded oil leak has reappeared again

Its got me puzzled(not easy I know), there is quite alot of oil all along the underside of the car but only on passenger side.

There is defo an oil leak at the cam wheels but Im not sure that its the main leak.

I have put all breather pipes into clear bottles to make sure its not breathing heavy etc but they were clear.

My question is, has anyone any ideas where it can be coming from?

It seems to be concentrated around the ARB bush on the passenger side and then blows under the car the faster you go.

What you guys think?

Stoo

Is this the same leak as before?

Graceland

Suspect - Rear Crank Oil Seal

PITA to get at, but 2 mins to change once you have taken the engine out

deffo engine oil?

not power steering fluid?

rapidcossie

Same leak as before Stoo.

Graceland its just had a new crank shaft seal, the leak is only on passenger side of the car.

No oil on the driver side of exhaust etc, so if it was the crank seal you would think it would be more uniform under the car?

Power steering fluid is red is it not?

rapidcossie

defo engine oil as i have just changed it and its not black yet, plus power steering fluid is still at max level.

rapidcossie

not when its dirty.....

engine oil isnt black when you put it in either

Stoo

Pisser mate. At least I can't be held responsible for this one though..!

rapidcossie

Its doing my head right in mate!

Its goes all over the back of the car when your going fast

First thought would have been the breather but if you have put the hoses into bottles it rules that out, unless there is a split hose or loose fitting under the inlet where it goes into the block.

Stoo

How come it went away for a while? I take it you found where it was coming from and now it's back? Faulty replacement seal or something?

Stick it on axel stands, lie underneath it and then get someone to run it up

its odd, i cant think of much on that side of the motor...


oil pressure switch.
standard breather port(block)
sump gasket,
does your block have the blanking plate below the dizzy? ive had a leak there before....

Mine was the same too, i'd hammer it, put it back into the garage and when i got the car back out bloody oil on the floor... ended being a leak from the sump on mine, it was throwing oil all down the car even onto the diff so it looked like the diff was leaking...

Used to come down the left side of the ARB and drip off..

Atleast it's good for under seal Euan..

probably from around the cam bearings - they need sealing in. it dribbles all down the block and drips off the sump bolts.

thoroughly clean the are first with brake cleaner and then use loctitie high temperature sealant with copper

Mine was still red when I took mine out after being in the car for two years..........

How much oil is there under the car. You said the cam seal was leaking is there oil making its way down the front of the block.

JTECH James

If your pushing towards 300bhp then you'll have to upgrade your breather system as the increased crank case pressure can force oil out all over the place. Are you near this power level?

1 bar sir

rapidcossie

It could be the cam wheels but it looks like too much for that?

It seems to be too far forward to be crank shaft oil seal so I think its something onthe engine?

Going to get it up on a ramp the mora, clean it all then go out for a run and see if I can see it.

justin.e

blowing past the dipstick?have you changed the o-ring??

rapidcossie

I didnt use any boost at all on my run this afternoon and it still leaked

rapidcossie

Its a new dipstick but its in the old tube.

that could be a shout actually mate.

Ill defo check it!

justin.e

Euan,
have seen it many times

big_wig_074

oil pressure switch?

rapidcossie

It just pulls out?

NEIL A

iTrader: (6)

check the dip stick tube and the fitting for the breather under the inlet, either of these should be easy to spot

NEIL A

iTrader: (6)

The tube should be in with a sealer and also be held in with a bracket by the inlet.

rapidcossie

Its defo no the fitting for the breather Neil but will need to check dip stick.

can only think of a few things on that side of block

oil filter housing
turbo feed line and pressure switch
breather port
sump gasket
carnk seal front and rear


thats it, so one of thos things, or as already mentioned its the cam seals

but how much oil is it

as 1 drop makes a big patch, and with ethe movemnet of the air can spread quite wide, so possibly a very tiny leak somewhere which will be a pain to find as normal

rapidcossie

ill go out and give it a try in a minute.
