Corolla SE Saloon 2002 1NZ-FE Swapped

[margallar]

i was getting that in cultus. yehi 100% masla tha

we even replaced headgasket. checked 1000 times, head was absolutely flat, block too.

in the end it was stupid welch plug in the head, which is exposed to coolant on one side and engine oil on other.

We replaced that plug and the white cream was gone within 20 minutes of driving car.

else it was same as your case, 1 liter of water every 2-3 days. Now same car is trusty workhorse

I don't get it how a leaky welch plug can cuase white cream on engine oil cap?

[margallar]

head mey tappet walay area mey oil hota hai, aur uske neche wali side pe coolant hota hai. plug head k andar laga hota hai, aur uski aik side exposed hotee hai.

Coolant pressurized b hota hai, tou wou engine k andar leak hota hai, bjye k engine oil coolant mey jye

One more thing I should mention that I was previously using 20w50. But because I heard that it is too thick for this engine I shifted to HX5 10w40. After shifting the mayonese appear after driving few kms and coolant started losing more than before.
I have poured whole 4 liters
Now I have driven 1000 km and the dipstick showing a quarter is less than the full mark and oil is dark in colour
I think it may be because thicker oil creates more pressure.

[margallar]

its not due to engine oil change, its just that the thin oil flows more and splashes around more, so it makes the moisture more visible. it didnt make it worse.

If you keep driving it like this, it may hydrolock and sieze

[hasankhurshid29]

I am parked the car and not driving it

[margallar]

good, let me show you, what i am talking about , looking for a pic

[margallar]

see the caps, i highighted with red marks

inke neche coolant ka channel hai, yeh agar leak kar jye tou head mey paani aata hai.

iss trha ki caps apki gari mey b hein. engine thori der chalaa k, tappet cover kholein, aur dekhen inn caps k aas paas cream tou ni bani hui. koi needle wgera rub krke dekhe inpe. aksar leak wyse pata ni chalta

@xulfiqar does this engine have welch plugs in head? is my theory applicable on this engine?

[dani_kk]

Wet test is really important for Cyl with 150 psi..
& for valves we need wet test information too.
& 20_25psi is not a good sign, nor you can consider it healthy by any means

[hasankhurshid29]

If we look closely zooming into picture
cyl 1 2 3 are at 170 psi
And cyl 4 is at 155 psi
15 psi difference only

does this engine have welch plugs in head? is my theory applicable on this engine?

yes - it has, infact in very similar spots too.

[hasankhurshid29]

yes - it has, infact in very similar spots too

So they may leak and can cause mayonese in engine oil cap?

[margallar]

yes it is

Going for the brake service of se saloon auto tomorrow early morning inshALLAH, after approx 1.5 years. Any suggestions or guide to take care of while doing brakes work? I also experienced car going on left side over 60km/hr speed. Should i go for alignment as well ? And also at 60km/hr speed emergency brake is not that effective. and move to left side and only left tire skits.

why not doing it yourself .. ?? servicing / replacing brake pads shoes are the easiest of DIY.

[def3nder]

My dad is not allowing me to do it at home, sadly Otherwise i would love to do it at home. If someone guide me properly, and the other factors regarding brake issues. as i have mentioned above.

[capsat]

ok. ask the garage to open & check the master cylinder over brake boaster, replace the kit with new one, check the front disc pads & rear brake shoes , replace with the a Grade item available near you , flush the brake fluid and bleed the system with engine reving at 1000 rpm. do not bleed with engine off.

adjust the rear brake shoes for hand brake. correct the tyre pressure in all 4 tyres and if vehicle pulls to left on free movement & when brake is applied, sure please go for alignment check.

good luck

[def3nder]

Thankyou.

Anyother input by any other brother ?
