Sir Johng napanuod ko video nyo kasi may plano akong 4jj1 swap Kaso paramg mali. Pag mas mataas ang RPM mas malakas ang blow by....... kaya lalo dapat naka buka ang PCV valve.....infact many Diesel engines na Common rail din walang PCV valve Baka idol ang PCV valve na iyan ay para sa "vacuum" pag bitaw mo ng gas pedal.... some sort of engine break (altgough wala naman engine break ang diesel kasi walang sumasara na Throttle)
Sir, More RPM should be more blowby Pressure in the crankcase side, ang more vaccum is in the intake manifold.Kaya Once High RPM PCV valve should open.
wid ol due respect bro, ARE U SURE ABOUT 4:50 to 7:18??? Ahouldn't it be the OTHER WAY AROUND??? when on IDLE position blow-by gases are @nominal rate while @ HIGHER RPM they tend to accumulate more...so HOW COME the PCV is at a CLOSED POSITiON when u need to ventilate the most? at IDLE position the throtle is simply ajar that tends to create vacuum due to AIR need defficiency thus the TIMELY NEED to OPEN the pcv for unused gases to be able to return to the intake??? KINDLY ADVISE...thx...
Sir kakapalit ko lng po ng valve cover gasket ng 4hji, dahil nag tatagasan ang oil, binuksan ko Yung PVC valve diapram , Wala xang espring, rubber lng, nag hanap ako sa outosuply Wala akong mabilis
Good day po, possible po kaya na yan din po ang cause ng whistling sound na parang hangin ng basyong ulan kung binibilisan ang takbo? Bale po nasa bandang air filter po ung sound kung papakinggan talaga ang pinagmulan
Boss patulong nman po kc yung 4hf1 engine bagong overhauled cya pero bkit tumatalsik ng langis s depstick..ngpalit nku ng pcv valve pero gnun prin...anu kaya problema nya boss.
Sir tanong ko lng po, saan po talaga nka pwesto ung spring ng pcv valve ng isuzu sportivo 4ja1? Cover then spring then diaphragm or cover then diaphragm then spring? Salamt po sana matulungan nyo po ako.
Sir good morning ask ko lang 1. May lumalabas na usok sa deepstick 2. Mausok na puti sa exhaust pipe Minsan nman nawawala 3. Ang isuzu hilander may pcv valve din ba
sir ung sken po 4hf1 ELF Truck, nag palit nko PCV Valve dahil sira rubber. pero my talsik prn sa dipstick talsik ng oil. pero pag inalis ko Breather hose nwawala. anu po kaya mganda gawen? Salamat po
Sir. Sa akin po tinanggal yong diaghpram niya. Kaya naka open na lang. Ang tanong ko po open na po siya pero bakit po may usok parin sa deepstick? Wala nga lang talsik usok lang po. Ano po pwede gawin sir? Thank you
Sir tanong ko lng po, pareho lng ba ang mechanism ng pcv valve ng 4jj1 at 4ja1? Kasi po ung nabili ko ay nasa loob ung spring nya between rubber diaphragm at cover. Salamat po
My Isuzu Panther (crosswind in philipphines, 4JA1L) has these problem : 1. White smoke coming from the dipstick 2. White smoke and sometimes black smoke coming from the exhaust pipe 3. White smoke coming from the breather hose that connect the pcv and the air intake hose 4. Oil in the air intake hose, turbo, and turbo hose (the one going to intake manifold) Please give me recommendation.. If i change the pcv valve (diaphragm) can my engine be free from those problem? Thanks 🙏🏻
1. Normal 2. Normal 3. Normal if no power loss 4. Coming from the PCV If theres no power loss i suggest bypass the PCV and cover the turbo inlet. Use long hydraulic hose so the oil vapor wont make a sticky mess on your engine. Long enough to go inside your chassis. Let the oil vapor lubricate it to make it water resistant (only if you wont get in trouble with the law in you country). If the pcv bypass is a problem for you use Provent Brand OCC.
@@JongTheDIYCarGuy wow, thanks for the quick reply ! So the suspected culprit is PCV ? There is power loss, i cannot run past 100 Km/h even in fifth gear (its a manual transmission) with the pedal fully depressed..
Sir Jong gud evening sayo.... Pwede ba ako magtanong? Ang d max ng kapatid ko, tumatakbo ng ilang kilometro tapos nag check engine tapos namamatay ang makina.... Please patulong po, ano kaya ang problema..salamat sur jong ..
Good afternoon sir.. Ung alterra ko may usok ang dipstick pag normal idle, pag rev naman nawawala, pcv valve ba possible na sira? Binuksan na ng mekaniko, buo naman ang rubber at spring nya..sana matulungan nyo ako..kakabili ko lang kasi, 2006 model, 213k odo..tnx n god bless
Sir sa akin crosswind tiningnan ko first time pa natanggal pcv diaphragm nasa gitna ang spring tiningnan ko kasi na notice ko na maraming oil ang napasok sa catch can ko mali ba yong position ng spring?
Sir ask ko Lang 4jj1 blue power euro4 engine ko lakas nang pressure nya May talsik nang langis sa engine cap at usok pero sa dipstick walang talsik nang oil pero may konting usok bago pa lang unit ko 2018 13.500 palang odo nya normal lang p ba yon sabi sa group nang Dmax normal lang daw Kasi overhead dual cam daw Ang 4jj1?
boss pa help nmn po be1 po bagong oberhaul at bago na lahat ilan palit na din kami ng ring pero itong last nasira un gasket ng diapram namin ano kaya sira may lumalabas na hangin sa butas na gasket ngdiapram ? ok paba diapram namin or sira na kc may hangin na lumalabas doon ?
