Sir tanong po. Paano po noong hinihigpitan ko yung drive shaft ng injector pump ay nag click 2to3 times yung parang umikot siya tapos noong inistart ko nag kakrank lang Pero ayaw na mag start at malakas vibrations tapos may naamoy akong nakakahilong amoy. Salamat po sa pagtugon.
I have a 2L engine I tuned the same way :) how I did the real test was making sure I have a nice road and at 100km/h I suddenly hit full throttle. I can feel the power. But I found if it's too rich the engine will produce a lot of smoke and the power will decrease slightly untill a higher speed was achieved. So I back off the fuel screw 1/8 of a turn at a time untill at 100km/h again I can hit full throttle instantly and I feel no power loss and still observing the smoke. When it's got perfect power it's a mild gray minimum smoke. It's an odd way of testing but too much fuel it will bog down and I have a feeling that's due to the advancement mechanism inside the pump at a given rpm and load. So 100km/h was my base to start it with. The 2L I have is fully mechanical and non turbo. Really enjoyed watching your video too :)
Thanks for the video. My 1995 Strada always felt a bit underpowered and after watching your video I tuned the fuel pump. It's so much better now and Im loving the new found speed. Thanks for sharing your video.
Iam looking for something on 4D56. Glad I found this. Good DIY, BTW nice clean engine....Love to see engine clean. Mine L049 1991, local assembly in Malaysia.
Great explanation and easy to follow and great video coverage which is clear, you can see the details you are doing. Btw saw your other video, are you based in the Phils? More power to you
Hello. I noticed at the end of the video there that you have some oil on the block of the engine. Is it leaking from that metal plate at the side of the engine?.. if yes... i have that same issue and would like to know how to fix it.
Very helpful, I have same engine. Can you please explain what increasing the fuel do to the engine temperature & how the power will increase. I run my engine at 12psi boost. I am told not to run it over 14psi.
Hi sir. Do you happen to have a video on how to adjust and introduce more diesel to a bosch CRDI fuel injectors? I specifically have KIA Sorento 2004. At cold start it has low power and having hard time to run but after being able to start running everything normalizes. The problem is from idle to start running. I replaced the fuel injectors the problem was solved but i want to know how to somewhat repair the defective fuel injectors and introduce more diesel to the injector. Thanks
Hello, very nice video, i have a galloper with d4bh engine, the compretions are 350 psi, i don't feel any lack of power, but it smokes badly, i had change the injectors new, maybe is the diesel delivery
Love your videos but my 4d56 is a turbo and electric throttle will it have the same screw as I’ve changed injectors and it’s still chucking a lot of black smoke thanks
Thank you and im sorry.I believe what you have is the 4d56hp d1-d common rail. Cant say im familiar with that sytem, still learning, but i doubt you can adjust that manually. Everything is controlled by the ecu ( computer box). I believe the best course would be to get an OBD scanner and check for error codes.
Have an L200 4d56 turbo intercooler giving me a lot of white smoke after diesel pump was serviced. Also timing mark on pump pulley is off by 1/2 a tooth. What am I missing?
hello , i have a hyundai galloper, with the d4bh engine which is the same as the 4d56t , thats in the pajero. , my engine has same fuel pump, my question is , on cold start , it is low on rpm i have to keep my foot on accelerator until it warms up and then it stays on the 700 rpm mark (normal) , how can i adjust the cold start idle but keep the same hot idle ?
great tutorial as always. I noticed that my injection pump fuel enrichment screw has a cover which keeps me from accessing the screw. Is it safe to just pull the cover off and wont it damage any of the parts near the screw..My van is Hyundai starex 97. Thank you in advance
Be careful when adjusting the fuel enrichment screw. If fueling is too high, not only will there be excessive soot production, the exhaust gas temperatures will get exceedingly hot. In some cases, cause the engine to overheat. Don't ask. Take it from my experience.
Which is better? A lot of black smoke or no smoke? More smoke = more power? Or how? And about tmperature..is this affecting temperature as well? Like .too much fuel can caused engine overheating? Is that true?
You need to find the balance, more power will give more smoke and higher power also increases temperatures. I believe the stock configuration of these engines are on the near-rich side, because since I decreased minr, (theres too much smoke whenever I speed up) I cannot reach 100kmh anymore lol
i am having a hard time turning over the engine after installing rebuilt injectors. i thought i bled the lines of air but perhaps i did not do a good job. i have tried cranking 20 seconds at a time and letting the starter cool at least a minute in between and i have not been able to start it yet. any suggestions?> thank you
@@MrDIYer okay i will try that. it started before i took out the injectors, though it was hard starting. i watched your video on crank/no start as well. i tried my best to bleed the IP all the way to the injectors. i have clear lines like you and i can see the IP has a solid line of fuel, but the outside of the IP won't fill the line with diesel. is this normal? will it fill once the engine successfully turns over? it tries and gets close to starting but won't stay running. i wonder if i flipped the shut off switch or something.
i have Pajero 2.5td is this video for 2.5td engine? i have problem with power, i put new turbo and still dont have power and have lot of black smoke? what i must to do?
you might want to check for excessive blowby. turn d engine on. open oil cap. if you see a lot of oil spewing out thats an indication you have a worn out engine especially if theres is white smoke coming out as well. do the same procedure on the dipstick hole as well as the pcv. if youre engine is burning oil as well.
Sir ask ku lng ung 4d56 matic pag nakalagay sa P and N bigla taas ng Rpm abot ng 1.8 almost 2 na..pag nilagay sa D balik sa normal na Rpm 1, wala po sya aircon.tnx
I have a 1991 Pajaro 4d56 turbo engine with a idling problem and I can’t figure it out When start start it idles up and down up and down but it rev very good with a lot of power and no smoke What should I do New lift pump and new filter already installed
Hello i adjusted mazda b2200 like you and it wont run anymore just starting i tried to adjust it back to where it was and still not starting could you help me?
Mababawasan ba usok sa ganito? Pasado naman ako sa emission pero parang mas mausok sya kumpara sa iba. Kapapatuneup ko lang (palit engine oil and filter, air filter at fuel filter, adjust valve clearance).sabi ng mekaniko, ok pa ang head gasket. Naisip ko lang na baka rich masyado ang air/fuel ratio ko
Hello, I own a Kia Cerato 1.6 crdi 136 HP vehicle. My car is at 86,000 km. Diesel is mixed with the engine oil, the oil level is constantly rising. There is no problem in the operation of my vehicle, the idle is normal, there is no noticeable black or white smoke from the exhaust. It works immediately with a single start in the morning, there is no problem. The technician said it could be the DPF and he removed the DPF and cleaned it in the machine. The DPF was around 40% full, but it was still cleaned. But that was not the solution either. Engine oil level continues to rise in my vehicle. I think there is no problem with diesel injectors because there is no indication of injector failure. The vehicle engine has a timing chain. Could it be from the high pressure diesel pump seal? Or what could be the problem? Could you help? Urgent. Thanks in advance
Check oil level only after 2 hours or more after the engine has been shutoff. Check the condition of the oil, it might be coolant mixing eith it and not diesel.
@@MrDIYer hello i have the same engine and i have a question about cold start mechanism of the pump, when you have it on can you hear the diference in the engine running? becouse i cant understund if it works or not, thanks
1 question bro, I have a vehicle with 4DR5 engine the problem is the engine idles rough at cold start I have to hold my gas pedal for like a min or 2, what do you think is the problem? Thank new subscriber here
Can you please help me sir, saan po pwede makabili inlet pipe o return line kung twgin ng iba? Inipit po kasi ng mekaniko ko yu pra daw tipid, e nag compute ako ng fuel consumption ko same lang dn kaya gsto ko ibalik kaya pi naghhanp ako baka po may alam ka po? Hindi ko po mai send dito yung picture n sinasabe ko baka may facebook kau pra maipadala ko po ung picture. Salamt
mabuhai, I have an L200 4x4 with same engine that I purchased recently. This pickup run underpowered and make lots of black smoke but only when accelerating. I haven't try anything yet the engine is very dirty and my plan is to clean first, But my though is if no one have touch the the fuel pump what can it be the issue? Thanks for your valuable reply
Have the same issue on our 4x2 L200, and the engine is NA and don't come with EGR btw Had thr injectors cleaned, smoke was reduced greatly but still not enough so I'm gonna do this soon and have the exhaust cleaned up
Sir pag ng adjust po ba nyan yung position ng injection ok lng po ba na nka gitna or original position ng injection pump ksi pg umaga hardstarting yung adventre tpos white smoke sya tpos few minutes mwawala na
depende. kung ang cause ng vibration ng engine mo ay low rpm, pwede. pero kung may ibang sanhi tulad mg worn out engine support o out of timing ang balancer shaft di mo maayos yan sa pag adjust lng ng fuel screw.
Why after I adjust the screw counter clockwise...it get harder to start..after that I rotate again clockwise to position before adjust..but still same harder to start..and after adjust idle to around 900rp..after I try to put on throttle..and release It stall to 400 for several second like It want to shut off
Sir yung pajero 1992 ko 4d56t hirap mag 100kph black smoke tagal bumaba rpm pag nag rev bago fuel pump, air filter and serviced intercooler. Maybe faulty injectors or fuel pump calibration at pwede din ba ibahin nozzle tip from 4m40??
