oily part sa engine

mga gurus, ano ba purpose nung hose na nakakabit sa valve cover ng makina going to the air intake tube(between the turbo and air filter)? medyo namamasa kasi ng oil yung connection near sa air intake tube(plastic). nagiging greasy tuloy yung area na yun at yung surrounding nya. the engine is 4jg2(trooper). well, sabi ni gary q. ganun din daw yung dati nyang trooper. is it normal?TIA.

I think thats the PCV (positive crankase ventilation).

Medyo oily din on my Pajero.

Otep, pati ba loob ng air intake tube(going to turbo) ng pajero mo ay medyo oily din? di ba yun masama sa turbo?

Yep. Meron konti. Ayoko na alamin kung masama. hehehe.

mga guys specially sa mga turbo with intercooler. PCV (positive crankcase ventilation) dyan lumalabas yung oil na moist galing sa crankcase and then going back to intake manifold. imagine kung babalik pa yan sa intake manifold maghahalo yung air and some oil papuntang combustion chamber it may cause mausok yung auto mo.kung may intercooler ka naman ang magiging cause ay babara sa intercooler. try nyo alisin yung intercooler nyo and tignan for sure oily yan. one solution dyan ay lagay kayo ng breather at tanggalin mo yung hose na pabalik sa intake tube.

otep: well, ganyan din ang pilit kong iniisip for the past few months. kaso pag binubuksan ko hood ko(to check oil,etc) lagi ko naaalala. hehehe.
yan_168: yun ding ang worry ko.
breather, eto ba yung parang filter na maliit (K&N miature) na nilalagay din sa butas ng camcover ng gas engines? di ba sya magbabara in the long run? pwede paki explain further, hehehe. sensya na ha.hehehehe.

Konting konti lang naman yung sakin, nakadikit lang sa walls ng hose. Nothing flowing naman. Engine heat pa lang siguro prito na yun.

The purpose of the PCV valve is to regulate the flow of crankcase fumes into the intake manifold where they can be burned. The PCV valve also has a secondary role as a check valve, to prevent flow back into the crankcase. This prevents potential ignition of the crankcase fumes, should the engine backfire. The PCV system is also crucial for to proper engine sealing. The system alleviates crankcase pressure, which can push out on seals and gaskets, contributing to oil leaks.

Oil in the breather filter may be a clue to gasket leaks in the crankcase or the presence of excessive blowby gases in the crankcase.

'Hope this helps...........
