Hilarious Stupid Funny Tricks/Works By Mechanic Ustaads

Hmm

Ask them why 2jz only takes 5 litres

[flyingfeather]

Took my city for oil change and booth guy be like “ sir 4 litre k dabba kyu lete hn 3 litre dala krn engine chota ha company n aese he itna bara oil chamber lga dia ha. I inquired if he knows how a vtec functions Seeing the blank look i asked him to just pour in 3.7 litres and finish the job

[anon35615524]

kiun k 4.250 ltr oil 1800cc gari mein dalta hay, is hisab se 1600cc mein 4 ltr or 1300cc mein 3.5ltr dale ga

And by that analogy, my 2.4L Accord should take 5.67L of engine oil, whereas in actual, and as per owners manual, it only takes 4.4L of engine oil with oil filter change, and 4.2L of engine oil without oil filter change.

Buss ALLAH Pa'ak Hi Reham Karein, and aesay mechanics sey Bachayein...

[anon35615524]

Never follow Mechanics Just tell them do task XYZ whatever it's And if somebody has doubt, ask on forums anyone can guide

one can't rely solely on these roadside Mechanics

Agreed. And not only here, but I think, in other countries too.

I later called that gentleman and asked him to fill up the quantity of engine oil as per owners manual, and never go to that oil change booth again.

I own the same car and i pour 4 ltr with change of filter each time. The oil level stays fine. Why pour 4.2 ltr? BTW i ve observed that not all but many manuals kind of overstate the qty.

[xenerking]

2JZ japani gati ka engine hay, aur wo japan aur europe k mosam k hisaab se bana hay wahan Karachi wala mosam nahi hota hay garmi kam.hoti hay aur hawa mein gutka naswaar aur tobaco bhee nahi hota is liye engine saaf rehta hay oil bhee kam dalta hay, wesay bhee japan ne itna kamal engine banaya hay sirf 5Ltr haaaail poore 10 ltr wala kaam karta hay us mein oil galleries aise banayi hain k oil double circulation karta hay...isi liye 3000 km par change hota hay..

Aur kuch mere laiq

[anon35615524]

Why pour 4.2 ltr?

Because I believe its mentioned in the owners manual, rest, let 1.6L Altis owners explain, what does Toyota Indus mentions in the manual about engine oil quantities?

The oil level stays fine.

Let me share another example: I have owned 3rd gen. 2015 model Vitz with 1KR-FE, and in the owners / users manual, it has been written that 2.8L of engine oil with oil filter change, and 2.6L of engine oil without oil filter change.

At 2.8L, engine oil touches the max. mark on dipstick.

Now if you pour 3L, level still remains the same, i.e. it stays at the max. mark on dipstick, and not crosses it.

I read some posts few years ago, in which some members stated that their "oil change mechanics" poured 3.2L, 3.3L, and even 3.5L oil in 2nd gen. 1KR-FE Vitz (where manual suggests ~3.1L of engine oil with oil filter change), and level remained at the max. mark on dipstick, and did not cross it.

[anon35615524]

So my point is, over-filling and under-filling both may be avoided, and dipstick may not be considered as a yardstick for measuring the exact engine oil quantity in engine. Of course dipstick can give a fair idea about oil level, but not 100% idea about the exact engine oil quantity present in engine.

I am of the opinion that oil may be poured in the exact quantity mentioned in the manual. If oil level drops, then it may be topped up accordingly.

[anon35615524]

but many manuals kind of overstate the qty.

But if they will overstate it, then leakages may start due to overfilling of engine oil, and none of the car assemblers / manufactures will want that the engines fail prematurely, or multiple problems arise in the form of leakages, etc.

Still, the question remains? how can under-filling damage engine seals?

YES. I know that overfilling is dangerous and it brings its consequences in different forms, but how can under-filling damage engine seals?

[xenerking]

i always thought that oil level showing between minimum n max points on dip stick is absolutely okay...it should not go below lower and not above the upper point....

and once i did overfill a mehran by half a ltr as i was tuned to 3.5 ltr...it was going okay then it started splashing oil from the dip stick tube and created such a mess which i cannot explain....however there was no leakage etc after the recovery process...Allah ka shukar...

so i know for sure that overfilling oil is really BAD for the car....atleast it creates a mess..
under filling ( a lil bit for upto 300 / 400 ml ) should go harmless....afterall all big engines consume oil of such magnitude...so how do they survive with a bit lower oil level in engine...

[anon35615524]

it started splashing oil from the dip stick tube

Of course it will do so, and overfilling can also make a layer of foam above oil level in the oil pan (due to splashing), and oil may not be able to fulfill its intended function (i.e. lubrication of different engine parts), bringing Havoc to engine.

under filling ( a lil bit for upto 300 / 400 ml ) should go harmless....afterall all big engines consume oil of such magnitude.

Agreed to a extent, still I am of the opinion that oil must be filled as per quantity in the manual, as you become worry-free after pouring in the exact quantity. Just check oil level after every week or 02, and if you drive it for ~4-5K Kms, and oil level on dipstick drops from the max. point to the mid, or let's say, slightly above even min. mark, still OK. Drain all oil, and refill.

However, if oil is already short of 300-400 ml, then one will have to periodically and continuously keep a check and balance on oil level on dipstick, as to when it drops / gets reduced? Nai tension...

Then 300-400 ml shortage of engine oil in a car which requires 5-6L engine oil, VS a car which merely requires 2.4-2.6L engine oil; lots of difference between the 02 IMO...

[Xulfiqar]

The reason the oil doesnt creep up the stick on overfilling is because the sump gets extremely wide above the required oil level, and putting a litre extra causes foaming (which can kill your engine) or pcv to stop functioning as air from under the cylinders cannot move in its correct path

[anon35615524]

YES. Totally agreed! And that's what I meant too by foaming (when engine oil is overfilled).

[Retaliator]

So my point is, over-filling and under-filling both may be avoided

That is alright. But since you have mentioned upper mark couple of times, my point it is not necessary to target the upper point. As long as the oil is somewhere near it then let out a fart or take a burp.

dipstick may not be considered as a yardstick for measuring the exact engine oil quantity in engine

how can a dipstick used for measuring oil anyhow? it doesnt have any gradation or has it?

[anon35615524]

Dear no idea about it.

I think, dipstick only gives a tentative idea about engine oil quantity / level in the engine. Rest, let experts guide better.

Sharing a recent debacle of a Mechanic Ustaad!

My Colleague a real innocent chap Owns a City 2007-2008, if you guys have read i posted a city which had to have an engine transplant it is the same car. a couple of days ago the speedo stopped working, My colleague took the car to his usual mechanic (who had ruined the original engine) and asked him to check. the Ustaad advised that the cluster must be taken out and repaired and handed and estimate, i called my collegaue just to check where he was and he told me all about the circumstance. i asked him to bring the car to office and give me 10 mins. \

i just opened the VSS, Sprayed some contact cleaner (happened to be present in my own car) Fixed it back and the speedo has been working fine since.

[ahmedstudio]

Guys can we please go back to incidents/stories around mechanic ustaads on this thread. Please do share your experiences.

[xenerking]

ustaad n team replacing mounts on a vitz 2001, installing new mount needed some adjusted and chota was ordered to lift the gear a bit so that mount could be aligned, super efficient chota immediately sources a scissor jack, put it under the gear n started lifting till we heard a cracking sound..

it was an auto gear n sump made of silver cracked with oil leaking...response from ustadd was worth listening...

on the same day, same chota lifted civic 2005 by using same jack under the front 'gadri. result was that only bonnet started lifting and wheels remained on ground....still remember the look on the owners face

[ahmedstudio]

Similar to this...read here a story by someone whose uncle got a new Corolla. It was his first experience of owning a car.

They met after two years and the guy asked his uncle: "aap iska engine oil kitni mileage ke baad change kartey Hein?"

Uncle replied: "engine oil change karna hota hai???"

🥴

This wins. Standing ovation for chotta.

(Read the first post in this thread...how a cvt gear ended up as a total useless piece of junk...just because of ustad's attempt to save his 50 rs + laziness by not installing a bolt)
