NORMAL DIESEL BLOW BY - DONT BOTHER TO DO THIS 

When he said “I don’t want you to worry about things unnecessarily” thanks dad!

Thank you for this, I traded in my MU-X for my dad's hilux and I never bothered checking for blowby until last week. Until I watched this I was worried as heck that the truck might fail on me as I was driving. No smoke out the exhaust even near red line, fuel efficient as hell (12km/L city) and no observable power loss. I thought that I accidentally got a junker because it was shooting out droplets of oil from the fill port on norml operation when I took the cap off. I can't tell you how relieved I am. Thank you

I genuinely thank you for this video

Very important infos 👍 we need another video showing us how bad blow by look like

Thank goodness, I just bought a 2nd hand Prado and got it home last night to see this amount of blowby. Thought I got a 🍋

Thanks for the info, I experienced the same with my chevy. And was freaked out when spray/sprinkles of oil was coming out of the oil filling cap. Thanks again.

Good informative, straight foward, no messing around. Excellent 👍

I agree there good engines my d4d hilux has 390000 on clock and has not missed a beat just had first set of new injectors put in at 380000 and a new starter motor and radiator a couple years ago that’s all I service it my self oil every 5 oil filter every 10

Its normal as long as how strong it tend to push the cap, the vacuum tends to suck it down. Whats important is that vacuum is as strong as how strong blowby is. It should be equal. Whats not good is that at cold start when you remove the cap, it smells like a over roasted beef or something like a cooked hair. Also at cold start, it should not have even a tiny bit of smoke coming out of the filler cap. But at normal engine temp, it should smoke the moment you remove the cap, but for 2-3 secs only. It should not smoke also at the oil dipstick. No smoke at oil dipstick means engine is at best condition. Dont worry if it has a tiny bit of blowby gas coming out of it, its absolutely normal.

The blow-by on 4JJ3 (MUX) is the same as in this video and I was a little worries and confused until I found this video. Thanks.

Thanks for the video. I have seen the same chicken little videos and posts about blow-by. All engines have blow-by. The more cylinders your engine has the less noticeable the pulses of vacuum and pressure. If one hooks up a manometer, they will also see pulses of both vacuum and pressure. This is normal as each each piston reaches TDC and BDC in cyclic pattern. If you set your manomter to log the average of those pulses, and your crankcase ventilation system is working properly, and you do not have excessive blow-by, then you will see an average reading of vacuum, generally less than 1 inHg. .

Thank you for pointing this out I'm sick to death of telling people this BS test is nothing.

Legend thanks 😂. We just worry about our Babies

Thanks mate I was starting to freak out until I seen this video

Yes I loved that choo choo, much rather hear your impersonation than hear it from my qd32t 🤣

Cheers mate I have a 1kz-te prado and i did this and was a little worried but its just had a top end rebuild and piston and rings done so i was a bit lost as to why it would be happening

Good video and straight to the point.

Great informative video. You’re a life saver

If you hear a humming noise from the oil filler hole and air pressure and oil bieng pushed out and your engine is burning oil there is something wrong with your pistons

The blow by on my 1.6hdi 300k+ km is double that and it runs fine, idles fine with out leaks. You might start to worry when you see white smoke from your exhaust

Thanks man for the video.

Mate my 4D56 motor runs pretty much identical as that motor in the video. If I take the cap off it splatters oil all over the place, but it has no blow-by at the Crankcase vent hose that runs to the catch can. There is plenty of hot air being pumped out of there but its always dry. I have done 65,000 K's and the catch can has been on it for 30,000K and the catch can filter is still as clean as a whistle. It's not all that noisy for a Triton either, it never runs hot & it goes like a rocket on the highway. It has got me miffed because I haven't seen any others do this. Most of the Triton's I have seen seem to pump out tons of oil through the crankcase breather tube.

Excellent video thanks keep it up 👍

What if theres an oil and smoke coming out of a dipstick?

What does it mean if you have small amounts of what looks and smells like exhaust smoke coming out of oil filler & dip stick hole?

What is there is smoke

Thanks for sharing Anthony. HooRoo

Where to find (positive crankcase ventilation 2GD-FTV hilux 2019

Hello I have an 06 Toyota hilux3.0 d4d 1KD engine I rebuilt the engine and one of the bolts on the injectors return pipe were loose so diesel flooded the engine I drained it tightened the bolts changed the oil it’s running but is there a probable chance I count have damaged the engine Please advise and thank you in advance.

Goood example chu chu thanks bro

Apprentice mechanic just did that to my 2015 Hilux ute, had 4 speckles on his hand and said it requires a rebuild, he's out of line?

Hello, good video, I had my motor repaired, replaced pistons, cilinders, valves, and still have a little blowby coming out from the oil filler. It may be normal, I hope until the piston rings get their possition. Now it has 6000 km of repaired. thanks.

1CD-FTV is blowing every oil seal, there is significant pressure building in the PVC pipe. I did the injector seals, no difference at all. Is it blown or something I could have missed?

Nice work

If it throws a lot of oil drops instead of steam is it considered to be blowby?

Just remember diesel the best

*Hello sir, when u take the video is the engine cold or normal working temp???*

What about when it sprays and covers your hand? Some have a little like yours but a petrol mazda? My hand has covered in black oil spots

Thank you

Interesting. Always asked myself if blowby is enginetype specific. The pressure is going to the air inlet. Depends on how this is designed?

what about smoke from oil cap ?

Hi mate, thanks for explain, but it’s normar too if there are Vapor?

Just did a rebuild (new crank, bearings), was running sweet, took for a 10min run, changed down gears from 5th to 4th & started to hear a rattle/knock?

Can you explain what's making that to happen over there. I'm talking about that small amount of blowby.It doesn't happening over the oil dip stick hole right.what the reason only for it to come over from oil fill cap port?

In my Skoda Alh, the cap dances and the crankcase blowby pressure is high. The breather/PCV is cleaner without any blockage. There is no oil spills anywhere. Is this normal?

is it normal to see smoke on 2.0tdi audi, when u open the oil cap??

They worry about that ahahahhah, bro my mechanic drained my gearbox and added aditional 5 liters to engine. 🤣🤣🤣🤣🤣

I've got a 1kz with 450k km+ and it has significantly more blowby through the cap but it's clean, zero smoke. Is smoke the indicator of a real problem?

Thank god

it is normal?? my 2.2 dicor Tata safari engine also have same cap jumping ( no gas come out from oil cap )

I turned the cap loose and it shot straight up in the air and now I can´t find the cap anymore, should I be worried?

I had this jerk tell me the pistons was gone in my van which was up for sale.. He had it running then taken the cap off..I couldn't understand how he could tell from just lifting the cap?

I nearly want to scrap my diesel vitara bcoz theres a little bit white smoke came out from the breather..can somebody tell me is that normal?

What does smoke mean ? The blow by looked normal but a fair bit of white smoke - also I could hear something electric sparking once engine turned off ???? Any tips guys Thanks heaps

Yep the mazda I mentioned

I laugh when i see guys on the isuzu pages taking the cap off and the chain flings oil out everywhere

Is it ok if engine blows up the air from dipstick? When you pull it out when engine is running... Thanks

Where is this blokes shop?

Why is the 1kd so loud??

I opendeed it and smoke and some oil cane out but not much air was blowing does smoke mean it’s bad?

Thanks for this video!!

And the cap rattles off into the fan and takes the radiator out 😂
