Customer Question

Hey I have just bought a 1997 ford transit custom 2.5l turbo diesel and it seems the oil breather pipe has been dodgied up with another pipe running into an old bottle with what looks like the pipe that should go on there is blocked off

There is a lot of oil around that area car is running perfectly no smoke just seems funny. The pipe that is bloked off runs into the air intake pipe

sound like the engine started making more breather gas or using a bit of oil and a previous owner has bypassed the regular feed back to the intake

now in theory this is fine but you will get a lot of fumes coming out of the neck of that bottle and the gases can often be explosive so I'd say its worth trying to put it back to normal to see how bad it is like this

if it starts running badly then I'd consider doing a compression test next to confirm that all the cylinders are within 10-15 psi of each other

Okay thank you there is quite a lot of oil too so I'm a little unsure of putting that back into the air take what could that be?
Expert:  Matt replied 1 year ago.


this sounds like the engine may be breathing quite heavily so the blow-by gas is pushing out past the pistons you will get a small amount of oil carried over in the gas

this is normal - but if its excessive hen it can give running issues
