I have a Fiat Tipo 1.3 MJET II and I noticed more oil consumption that usual when the car starts up it will blow out smoke and I believe something leaking overnight I’ve been told it’s Oil sump then told it is valve stem seals the bottom end is strong, fresh timing chain, turbo so the car basically has a rebuild and the mechanic may have messed up on the valve stem seals is this a big problem or no? I put In supercharge oil treatment and the consumption drastically reduced I might need to look into increasing to 5w40 and change FRAM oil filter to MANN
