Nissan Navara NP300

mga 2000KMs na since i blocked the EGR. hinintay ko lang matapos warranty.

2 blocking plates ito, tanggal yung tube. medyo madami na soot yung tube. tanggallin lang hose going to the air intake and accessible na yung EGR ports.

no check engine light so far. more responsive on low end, and mas 'usable' na sa city and mountain climbs. nahahabaan kasi ako sa gearing nung 7AT.

another reason of blocking EGR is for cleaner oil - lahat ng blocked vehicles namin medyo golden pa oil sa dipstick, compared sa open pa EGR at 5000KMs na sobrang itim na.

nagtatanim na lang puno to compensate

Kumusta ang egr mod, wala parin CEL? Antaas ng upshift RPM ng 7AT need manual mode everytime sumisibak, next project ko after warranty baka pwde trans reprogramming kahit sana 1.7k rpm ang set upshift.

Tailgate additional damper mod.

bolt-hole of lower bracket is off-centered, needs some shaving using round file.

Damper cost P900

Sorry ngayon ko lang nakita, walang CEL with the EGR blanking. Mas may 'oomph' on lower RPMs and at about 1.8K kaya na niya mag upshift.

Meron akong P0380 code pero walang CEL. Glow Plug/Heater Circuit A.

Accessible yung glow plug when you remove the top engine cover pero masikip.

Gusto ko sana i test yung resistance para malaman kung failed glow plug nga ba, or relay/timer, or etc.

Nakita ko yung glow plug relay just behind the left headlight (facing the NP300, katabi ng air box). Nag continuity test ako sa 2 connectors and OK.

Pero walang lumalabas na value sa VOM ko? I only have a cheapo XL830L now and walang mahiraman na ibang tester.

Kahit naka 200ohm setting na wala pa din lumalabas. Nirekta ko na din yung probe sa mismong tip ng glow plug and 0 pa din. Di ko matanggal yung glow plug kasi nga masikip.

Nag sanity check naman ako and tested resistance sa isang unpainted bolt and may lumabas naman.

Kung may dead nga na glow plug yun lang sana palitan ko instead of the whole set lol. Tumawag ako sa mga ilang auto supply and yung OEM glow plug is around 3K+

Analog multimeter gamitin mo para real time. Pero kamo shinort mo test leads at may reading pero wala sa plugs? bka nga busted. Wagmo muna tangalin hangat wlang kapalit, minsan kasi na stuck yan sa kalawang need mo ibabad brake fluid bago tangalin.

Ang issue lang talaga ng D23 yun rear brake shoe maingay sa una. Sana naman sa next facelift gawin na disc brake likod wagna tipirin, si greatwall nka disc brake narin.

May nahiraman akong tester pero cheapo one din. Same result walang resistance.

Thought na impossible ito so nag probe ako ulit sa mismong glow plug. Walang continuity to ground?

Nissan calls this part Timer Assy, Glow. Not sure kung may iba pang glow plug relay, wala na ako makitang related sa parts catalog and sa engine fuse box.

I disconnected it from the connector below and ok naman from cold start.

This attaches to the thing above. From the pins papuntang glow plug connector, meron continuity and resistance. Pero pag nakakabit na yung connector sa glow plug, walang resistance and walang continuity sa ground.

Not sure kung user error

Bro, what do you mean by "mas 'usable' na sa city and mountain climbs"?
Thanks

googling,
"the normal resistance should be no more than 6 ohms.", whether analog or digital yung tester.

are all your glow plugs dead?
yike$!

and yes,
i wouldn't remove 'em, just so's i can check 'em, for the same reason as given above.
dapat may ka-palit na, or sa shop ko patatanggal.

Before nagloload lng ako ng 33 sacks (25kilos/bag) ng bigas including sa loob ng cabin using stock EL coil spring pansin ko hindi aabot ng 1ton ang load. sag na maxado tignan ang navara namin. ang ginawa ko naghintay ako ng may magreplace ng coil spring ng 2023 model. Kc nakadual coil rate spring itong latest model. so binili ko yung kanyang stock dual coil spring. at ayun kaya ko magload ng 1ton sa likod nahindi pa natatamaan ang rubber damper nito. 1 ton load + 3 person inside sa cabin.

nakahanap ako ng replcement glow plugs at around 3200 for 4 pcs, pero ayaw ko kasi maging parts replacer and dasal na lang.

i want to be certain kasi and na exhaust na all possible troubleshooting steps para di sayang pera.

umakyat ako recently to a mountain town and it knocked on startup

nawala naman when it warmed up. i guess it will behave like this everytime it is cold until i fix it.

blocking the EGR resulted in earlier shifting for the vehicles that i've done it.

not sure kung tama understanding ko, instead of redirecting a portion of the exhaust gases back to the intake manifold, when you block the EGR diretso kaagad sa turbo so the turbo spools quicker.

around 1800rpm nagsshift na yung 7AT, while before you need to push it around 2000rpm pa. and the intake will be a lot more cleaner when you block the EGR. cons lang is higher NOx emissions pero LTO doesn't test for it.

magkano and saan kayo nakakuha nung newer OEM coil spring? pag nagkakarga ako ng lupa halos sumasayad na pero still within the loading spec pa din naman.
