Nissan Sentra: Water mixing with Oil

**daxbrandy** · July 17th, 2011 02:24 PM

Hi guys this is my first post and I needed your help regarding my car problem. My car, by the way is a Nissan Sentra 2000 (exalta body, engine: GA14). About 3 weeks ago, I noticed that there's oil in the radiator cap and the oil in the dipstick was like a milkshake. So, alam ko na na may problema at kailangan ang top overhaul. I brought it to a car shop para maayos. Ang ginawa nila pina-check muna ang block kung warp sa machine shop. Ang findings, OK naman daw kaya natapos ang top overhaul. It took them 3 days to install everything.

After one week of using the car, eto na naman, naghalo na naman ang tubig sa langis. So ibinalik ko ulit sa shop. Ibinalik nila ulit sa machine shop ang block at dun na nakita na warp daw pala... (ibang tao ang nagcheck). So ni-resurface ang block based dun sa findings. Then gawa na ulit ang car (of course, with new gasket, new oil, etc) This is a back job so walang bayad.

Unfortunately, after one week ulit (7-days), naghalo na naman ulit ang tubig sa langis!

Ano po kaya sa palagay ninyo ang problema nito?? Workmanship ng shop mechanic? Poor or substandard gasket ang ginamit? Wrong judgement/diagnostics ng shop mechanic?

What do you think about refurbished/surplus engines? Where can I buy good surplus engines? Is it worth replacing the current engine or just buy a surplus cylinder head block? I'm planning to bring my car to Nissan and have it checked pero natatakot ako sa over-estimate/charge ng mga casa.

Need your inputs and opinion and advise mga masters. I live in the southside (carmona, cavite)

Maraming salamat po.

baka mali yung pag kaka torque ng turnilyo or mali yung torque sequence?

most probably yung transmission oil cooler ang busted not the head

or the engine oil cooler (oil filter base)

pwede rin may internal crack na. try leak-down testing or pressure testing sa specialist.

the original post indicates one thing.. the seals even after replacement keeps breaking because of pressure. pcv must have been stuck and needing replacement.
