Dieseldude,

one more time.

my battery just gave up this afternoon....i jumpstarted it using a battery from a nearby batt shop...upon starting, white smoke came out and after a few acceleration there's still white smoke but on the way home it was black again during sudden acceleration....i found out that the solenoid connection is loose...had some checks with the batt shop using a meter....batt shop said nothings wrong with starter (probably), alternator and battery..problem is with the wirings.

ang palaisipan e bakit ngayon lang nangyari e matagal nang lazy starting ang engine...with regards sa short-to-grounds, mabagal na trabaho ito kung meron man...

plus i've read from a foreign forum that timing retard also causes turbo lag...mejo may koneksyon ito sa problema ko kasi nga di ko na marinig sipol ng turbo kapag acceleration.

kindly enlighten me sir. TIA

Dieseldude!

tanong ko lang kung bakit naging delayed yung shifting ng pajero ko after magpacalibrate? sa inyo po ako nagpagwa mag 2weeks ago na pero before naman magpacalibrate ok naman shifting ko ngayon ang hirap pumasok ng 2nd gear at 3rd minsan hanggang 40 lang ang natatakbo ko kasi ayaw mag engage ng gears at pakiramdam ko tumigas yung pedal ko 2days ago ko naramdaman yung pag tigas ng pedal. Babalik ako tom sa CDC andun kaya ikaw tom?

Hello Rio..... Lumuwag lang ang downshift cable adjustment, chaka nilubricate ang cable. Kamusta na ang shifting ngayon?

Hi sir andun ba kayo nung ginagawa pajero ko? parehas kayo ng sinabi ni sir antonio:D much better naman kesa before pero di padun ganun ka ok ano kayang maadvice niyo saakin?

Pasyal ka nalang kung may panahon ka. Tayong dalawa ang mag test drive.

my engine overheats faster than before prior to the HG replacement. What is the HG?

would an injection timing be the cause? during the reassembly i accidentally rotated the IP sprocket about 1.5 turns cw when installing the timing belt.... engine power also feels lower plus it seems my FC increased. engine is 4D56B air cooled turbo. Check injection pump timing.

i replaced and retightened all loose bolts connecting battery and starter motor yet it still starts at a lower rpm. Weak battery maybe? How old is your battery?

TIA

kindly enlighten me sir. TIA

Is the CKP rotor on a diesel engine vital to engine starting? We overhauled a diesel Hyundai Santa Fe and were not able to make it start ever since. After a co-mechanic suggested the CKP, we tore down the engine again and noticed the wheel with several notches bent..

ocge po sir anong oras kayo pwde tom? baka pwde niyo ma PM sakin ang contact number niyo para ma text ko kayo bukas pag papunta na ako salamat sir!

Salamat ng madami DD sa replies....

nga pala HG is head gasket...sorry sa abbreviation.
my battery is motolite gold N70 which is about 1 year and a month old.
4d56 diesel mated to an automatic tranny...i drive it about 5 days a week with A/C running most of the time...i suspect that the A/C kills the battery fast...checked the alternator and it was good using the Sun vat meter at the battery shop.
i'll have the timing checked this afternoon and i'll update regarding sa performance....
thanks again

sir DD,

just came from the pump specialist...told me the timing is good as long as the timing marks are aligned...yet he adjusted the shift cable for the transmission plus tightened the fuel adjustment screw because it is leaking...the acceleration feels smoother now...

as per his (mechanic) observation of the exhaust gases during sudden acceleration, the engine is fine except for some blowby. the blowby is acceptable since the engine is getting old.

Is the CKP rotor on a diesel engine vital to engine starting? Yes.

We overhauled a diesel Hyundai Santa Fe and were not able to make it start ever since. After a co-mechanic suggested the CKP, we tore down the engine again and noticed the wheel with several notches bent.. Why did you initially overhaul the engine? Did you ever find out the cause for the bent teeth?

Sent you PM Gio.

sir DD,

Good. Are you now happy with your car's performance?

as per his (mechanic) observation of the exhaust gases during sudden acceleration, the engine is fine except for some blowby. the blowby is acceptable since the engine is getting old. Possible...

Since the wheel was bolted at the end of the crankshaft and was not taken out of it, we know now the crankshaft was unknowingly dropped by our mechanic or still possible, while being at the machine shop as evidenced by the scratch marks on where the teeth are bent.
The engine was overhauled due to mechanical knocks caused by poor oil change intervals and prolonged low oil level.

Will you replace or repair the wheel?

My boss will go to Korea tomorrow so we will buy it there, but lately we were having problems with the availability of some Hyundai parts from there so I'll have the wheel aligned by the machine shop to be sure.

sir mejo OT lang useful ba ang oil catch can for our 4M40? what are the advantages and disadvantages of using this?

Alignment by machine shop is possible. It should also be balanced to prevent vibration at high rpms.

Why do you want to do this?

ingat lang po sa pag-gamit ng oil catch can dami na kasi akong nabasa nasira ang engine dahil dito, gusto ko rin sana lagyan ang frontier ko kaso nagbago na ang isip ko nung nakabasa ako ng mga negative results ng oil catch.
