Sir dieseldude, medyo out of topic po, pero maglalakas loob lang pong magtanong, ok po na maglagay ng 2T oil sa diesel na 1 part 2T sa 200 parts diesel? Navara 2009 po ung ginagamit ng tatay ko. Safe po ba ito. Pasensya na po kasi newbie po talaga ako sa diesel engine. Many thanks in advance.

Hindi ako makakabigay ng tamang payo sayo dahil wala akong formal advise galing sa FIE manufacturers. Chaka wala din akong experience dito.

Ngunit, sa usapan namin ng mga diesel technicians, delikado mag halo ng oil sa diesel dahil lalapot ang viscosity ng fuel. Baka masira ang common rail nozzles dahil napaka liit ng spray holes nito compared to the older designed nozzles.

Hello All!
1) I tried the "search this forum" button but could not find info on my question (closest i got was oil bypass filtration,or maybe its somewhere there??). I`m pretty new to diesel. I have a 4dr5 powered highhood jeep. There apparently is no built in Fuel/Water seperator! Is that normal for the 4dr5 or is it hidden somewhere? Otherwise, is there a correct specification fuel/water seperator (even an aftermarket aka replacement)? Or can i just use anything that fits? I just had some fuel system work done, so sayang naman if i dont take care of my engine.

2) Also my element type oil filter leaks at the point where the oil filter housing contacts the base (the one you screw the housing to with a single bolt) even when i tighten up the bolt on the filter housing. I`m used to tightening up regular spin off disposable filters tightly by hand only, masama kaya yung bottom oil filter oil ring ko? Its a new o-ring! Thank You! patrick

I have a 4dr5 powered highhood jeep. There apparently is no built in Fuel/Water seperator! Is that normal for the 4dr5 or is it hidden somewhere? Yes it is. The 4DR5 does not originally come with a separator. Otherwise, is there a correct specification fuel/water seperator (even an aftermarket aka replacement)? Or can i just use anything that fits? I just had some fuel system work done, so sayang naman if i dont take care of my engine. Any separator for a similar engine displacement will be fine.

DIESELDUDE-
Thanks for your reply! I got a nippon water seperator. Sa oil leak question ko, i just meant if there was anything out of the ordinary that might be causing the oil leak. Ok, i will doublecheck the usual things like tightness, or even wether the flange surface is contacting the filter correctly(??), etc.. Thanks again! patrick

Thanks for your reply! I got a nippon water seperator. This is ideally mounted before the feed pump. Does it have a filter and glass bowl? How much did it cost?

Check the square-cut oring which goes into the groove of the filter head. Thanks again! patrick

P280 for filter only (i have the old mount) and no glass bowl. I will check oring. thank you!

Hi DD,

My choking problem keeps on going back everytime my fuel level reaches slightly below 1/2. Ano kaya ang problema? I already replaced several fuel filters, scv. Napansin ko lang lately pag full tank ulit ako biglang nawawala ang problema. I think there is air going in the system. Whats the first part I should test?

Thanks sir!
