30 psi lang pag solo performance, pag me sakay sa likod add lang konte up to 35 psi.

Thnx bro. Nasubukan mo na ba around 40psi? naka-indicate kasi sa gulong up to 65psi max.

Anyway isa ko pa problem is pumapasok sa radiator ko yung engine oil kahit napagawa ko na, sabi ng mechanic mga tira-tirang engine oil daw yun na nanggagaling sa engine block. I hope so kasi advice nya sa akin weekly ko daw i-drain yung radiator ko para luminis. Pero ang gawa ko is every 2-3 days linis ako radiator then palit tubig. Sana nga wala naman crack yung engine block ko kasi napa-top overhaul ko na po ito.

Yup nasubukan ko na 40 psi, matagtag especially me add-on ako na leaf spring sa likod. 30 psi ayus na yun.

If you don't mind bakit top-overhaul ang ginawa sa makina mo anu ba naging sira?



* Col_em around 350K would be a good figure... diesel naman kasi kaya mataas resale tsaka Isuzu. Lam mo naman marami tyong mga panatiko sa Isuzu diesel hehehe

Hindi pa po nakaranas palit ng oil cooler yang makina? Yan ang sakit ng OEM oil cooler from thailand. Na experience ko yang problem. Naipost ko dito somewhere in isuzu thread.
I suggest bili ka ng oil cooler at palitan. Oil cooler yan mismong pinapatungan/kinakabitan ng oil filter. Maybe 4K or a little more ang price just my guess.

*blue_gambit,
naging problem po ng hilander ko is baka daw nagka-leak sa oil filter, or sa gasket ng engine block or my crack mismo engine block ko kaya naghalo yung tubig ng radiator at engine oil ko. Tama po ba na top-overhaul ang gawin? bale nilinis kasi yung buong radiator kasi nga dami ng langis at baka daw pati yung tubig eh pumasok na sa engine mismo. Tapos linis din yung engine sabay change oil na din (due for change oil na din kasi), then tune-up. Hirap ng walang masyadong alam sa sasakyan. Ngayun kasi may napasok pa din na engine oil sa radiator ko, pero tira-tira na lang daw po un kasi di na po nalinis ung mga sulok2 ng engine block dahil sobra kipot na daw po pa tanggaling yung oil leak. Tama po ba ung proceso na ginawa ng mechanic?

Comment naman po mga experts jan.

*weisshorn,
Thnx for the reply. Any particular brand po ng oil cooler na gamit nyo ngaun? Matagal po ba bago nawala yung oil sa radiator nyo? Tama po ba top-overhaul? May chance po ba talaga na pumasok ung tubig sa loob ng engine? Sorry ha dami kong tanong,

Not sure kung nakapagpalit na ito ng oil cooler kasi July 2010 ko lang po ito nabili (2nd hand).

Oil in the water or vice-versa usually means a busted head gasket. Are you overheating? Change the head gasket first if budget is limited. Hopefully, that fixes that - or at least lessen the problem. If not, save up for an overhaul.

After all the works done to your engine I'm pretty sure that the oil cooler is the culprit. I've been in that situation before. First I suspect head gasket so I pulled out the cylinder head. Nothing found there. next I pulled out the oil cooler. done hydro-test. at first I cannot see any significant leak but after about 20 mins that the cooler is submerged in the water I've seen one small bubble, yes only one bubble. That's time that I conclude that the oil cooler is leaky. Yes only one bubble but when the engine is running and temperature is hot this leak will be stronger. After changing this cooler the problem was fixed. This was several years ago. If you care to back read/search you will find my early post. Good luck.

By the way all were DIY.

If there's crack in the water jacket, cylinder head or any parts adjacent to the combustion chamber this will result to combustion leak going to the water side. You will smell combustion leak in the radiator and observe water bubbles. Amoy usok po yan. Also this will give white smoke out of the tail pipe. In the absence of this means leakage is somewhere else.

Thanks for the reply. I had it top over-hauled, replaced the head gasket. Pero may oil pa din sa radiator ko. Tama po ba explanation na tira-tira na lang yun from the engine block or kailangan palitan na mismo ung pinaka-socket (don't know the term, he3) ng oil cooler? Please keep the experts opinions coming. Thanks in advance
By the way I didn't experience overheating kasi I regularly fill up my radiator especially on long trips.

I was asking why the need for top overhaul. Does it burn oil? nag babawas ba ng oil? over heat? loss of power? loose compression? before it was overhauled by your mechanic... If No to all, no need for top overhaul and your mechanic was wrong I'm afraid.. those are the only basis where full or partial overhaul is performed .. IMHO

If his analysis was correct, His workmanship is poor. Sorry...


I would concur with the consensus of our fellow "Hi-Lander's" that the oil cooler is the culprit. It's the base where you mount the oil filter and also where oil and water run through a channel closely. any leak from either will produce the symptom your experiencing... oil and water mixing in the radiator..
