Dealing with engine oil leak concern on my 2014 Volkswagen Polo TSI


My automotive has accomplished 1.05 lakh km & I’ve had zero expense on it aside from the common upkeep.

BHPian kp.2008 lately shared this with different fanatics.

Hello people,

I left my Black VW Polo GT TSI (2014) for the 1.05L kms service at VW Bangalore North yesterday. In the course of the inspection, we observed an engine oil leak beneath the bonnet (photos connected). The SA mentioned he’d get it examined. Right now, I’ve obtained a quote from him that a number of components (totaling 37k + 10k labor) have to get replaced (record connected right here). This looks like they’re doing trial-and-error moderately than a correct RCA to know the rationale and suggest the proper repair. Request the consultants on the discussion board to assist me.

I’ve had zero expense on this automotive aside from the common upkeep – had a gearbox failure at 42K kms, however that was lined beneath guarantee.

This is what BHPian vishy76 needed to say in regards to the matter:

Evidently this oil leak will not be very fast-paced but it surely has been seeping for an extended. It is extraordinarily tough to pinpoint what precisely it could possibly be just by wanting on the underbody as a result of oil has splattered far and wide. The S.A has cunningly billed you for nearly each possible seal that may leak oil.

My suggestion is to wash the whole mess up first and ensure there is no oil residue left behind. Fill recent, new oil in, put a brand new oil filter and drive round for about 50-60km. Then verify once more. It is possible for you to to determine precisely the place the oil is coming from as a substitute of doing guesswork. All oil seals on an engine do not leak on the identical time.

  • If the leak magically stops, it is your oil filter O-ring that was leaking which was remedied once you modified the filter.
  • If the oil is seeping out from the perimeter of the oil sump, it is the oil sump gasket that is at fault. Change it with all of the bolts.
  • If the oil is seeping from the realm the place the engine meets the gearbox physique, it is the rear foremost oil seal (crankshaft seal on the flywheel facet) that’s the offender.
  • If the oil is leaking from the driving force facet engine space (close to the serpentine belts), it is the crankshaft seal on the crankshaft pulley facet that’s unhealthy.
  • If the oil is seeping from the timing chain covers, it is the seals on these that are the offender. I’m not positive if the 1.2 TSI makes use of a rubber gasket there or a gasket maker (sealant similar to Anabond). I consider it’s the latter, but it surely’s higher to verify as soon as.

One other factor it is advisable look into is why your thermostat housing is being changed. I do not assume it has something to do with the oil leaks.

This method may appear cumbersome, but it surely’s higher to be doubly positive after which try to repair this concern. From the pictures a minimum of, I’m discovering it extraordinarily tough to pinpoint the origin of the leak.

This is what BHPian SPIKE ARRESTOR needed to say in regards to the matter:

I observed the spare half prices to be a bit on the upper facet, I could also be incorrect as I am not conscious of spare half costs of VW automobiles, is that this estimate taken from their spare components database? To me, it appears inflated.
