Help regarding oil leak!

[tomoeshinji]

Hi guys,

*Disclaimer*: Halos wala po ako alam sa sasakyan.

Tatanong lang sana ako, pinacheck ko kasi yung sasakyan kanina kasi nag lileak yung oil ko. Pagtingin ko sa oil level halos wala na although matagal ko na alam na may tumatagas. Dati kasi nung nagpachangeoil ako sa casa na determine na naloose thread daw yung drain plug ko, sabi na kelangan irethread at ibaba yung oil pan kasi maglileak nga daw. So kanina dinala ko sa isang shop and sinabi ko na yun ang sinabi sakin sa casa. Tapos ngayon tumawag na hindi daw yun ang main reason kung bakit tumatagas ang oil, sabi nya yung front crank shaft oil seal at rear crank shat oil seal daw ang reason. Halos negligible daw yung sa may drain bolt. Ngayon tinanong ko kung magkano, sabi nya 9k, sabi ko mahal, kaya nya daw ibaba sa 7.5k. Ganun ba talaga kamahal yung paayos nung front and rear crank shaft oil seal? Sabi nya ibaba daw kasi pa yung transmission? If mahal, can you suggest a shop near makati where it is cheaper than the given quotation?

Please help, it would mean alot to hear your feedback/suggestions.

Thanks!

Hi sir,

Dapat humingi ka muna ng detailed job order nung gagawin sa kotse mo and kung ano ung parts na papalitan nila. Mura lang naman ang oil seal ng front and rear crankshaft.

Kaya siguro mataas un price eh mapupunta sa labor lang kasi madami kasing kailangan kalasin para lang palitan ung oil seals.

Ang gagawin daw is, bababa ang transmission, replace rear crankshaft oil seal, balik transmission. Then baba fan blade and something about timing belt, then palit front crankshaft oil seal, then balik lahat.

Tama ba yan?

Vehicle is Nissan Frontier 2004 model 2.7S btw.

Front seals R&R usual price is : >= PhP1k (requires removal of engine accessories, fan, radiator, belts, chains, covers, pulleys, etc.)
Rear seals R&R price : price greater than the front since it requires removal of transmission, propeller shaft, flywheel and clutch assembly while doing it lying down on the garage if mechanic does not have a car lift.

Eto mga nasa isip ko ngayon na parts:
1. Chain (if ever loose). If im not mistaken your engine is TD27 right?
2. Front Seals (crank, cam, balancer if so equipped)
3. Rear Seal
4. Clutch if heavily contaminated with oil
5. Check release bearing if it needs replacement since your mechanic is "already there".
6. Oil pan gasket

Good Seals are cheap pero the R&R labor is not.
