bust EGR valve, i have one if you need.

hi there how much and is it easy to fix is this a common fault thanks

you sure it's coming from up there, as I would't have thought much oil could get past the egr valve, as it has no connection to any oilways. Sure it's not a bit lower down, around the top little pulley area (arrowed on your picture)

[dazrecoverymad]

it possibly could be from the pulley area is hard to tell though theres quite a bit of oil around the whole area /i will have to give it a steam off and keep checking it what is the pulley connected too ?

[winterheating]

if theirs oil all over its more likely that its from a boost pipe or EGR valve. DEpends on what the engine is breathing like, what type of oil is used and what condition turbo is in.

i was just goin on what aph said /that there was no oil connection with egr valve /it does look like its coming from there though turbo is on opposite side of engine thanks/does egr valve have a connection with oil system

[winterheating]

turbo boosts air in the boost pipes , oil seals can pass a small amount of oil normally, but sometimes a lot, EGR valve is inline with boost pipe to intake.

oil leaks are more common at the vac pump and gasket though (arrowed)

[dazrecoverymad]

could possibly be the vac pump then /do i have to replace the whole thing ?

Sometimes it just leaks from the gasket between vac pump and water pump, so replacing the gasket can often do the trick.

[dazrecoverymad]

is it hard to replace the gasket thanks
