96 Indus Corolla problems

[pwuser149294234830]

@pwuser147983858371
yes you are right their is problem in my car wiring and computer is also repaired as yousaf bhai told me and original japanese engine is expensive thats why yousaf mechanic demand is bit high and he said that we should clear every thing.
but still my question is that what is the guarantee of fuel consumption that new engine will give me 15km\ltr at least on long with light foot and manual gear.

[trouble_maker]

I can almost gurrantee you that a 5afe will never give you 15km/l in city it is a very old engine with a "dumb" ecu

[pwuser149294234830]

@trouble_maker

i am asking 15/ltr on long

[pwuser147983858371]

If wired properly than 5AFE can give 15 on long.

Thanks to every one one last question

I have purchased this car Xe Gli 1.6 isb number black colour about 4 months ago in 7 lac and if i change the engine and also tyres because not in good condition and little more work it will cost me 8.50 lac so plz guide me what should i do,
1- switch on cng
2- spend money on this car like sswap of complete Engine
3- or sale it and go for any other car
very upset

waiting for your kind opinion

@SER_GTR and @CAPSAT have done a swap of 5AFE in a indus last year.

the yard engine despite our careful extra ordinary surgeon eye inspection it spitted over our face as in consuming oil in under 5000 kms again.

Now the old engine we have kept is under overhaul. as per FACTORY Specs., we used ustad workshop as base station engine is almost assembled and ready to come back into engine bay. THE present 5AFE is consuming oil and we plan to over haul it later part of year when time permits.

5 AFE surely can produce a nice fuel average of 12+ with ac in city and close to 15 over highway. make sure that Burraq does the compression test and valve seal check up etc before engine is rigged in the car.

your money your call. It is winters now & CNG load shedding will be announced anytime soon in KPK & PUNJAB.

[SER_GTR]

My Advice...Sell The Car Or Overhaul It....The ECU And Wiring Will Not Cost More Than About 10k-15k.....

For Smoke...Do Dry/Wet test...If Compression Are All Good And You Have Smoke Issue...All You Need To Do Is Get Valve Seals Changed...

Even Changing Rings And Seals On This Engine Shld Not Cost Above 10-15k Itself...A Proper Mechanic Who Knows Work Can Sort This Issue In Less Than 30k...My Rough Guess

I Have Been Through These All...Changed Swap Engines So I Know Yard Engines Speciallay A Series Do Need Ring Changes Due To Failure Blockage Of Its Favorite Oil Ring Issue

Swapping And Expecing 15km/L From 5AFE Is I Guess A Very Tough Call

My Advice Remains Same...Sell Or Buy Later Gen Car And Invest On Purchase Money ...Or Find Someone Who Can Mild Rebuild This Motor ....@vaqas1 had enough of these things mentioned with his car...contact him for better advice of mechanic

@SER_GTR @Vaqas1

Thanks
yes i am also thinking to sell the car or switch to cng,
and what you think by overhauling the engine and complete new wiring+ECU the fuel average will be better.

or if i sell the car in between 6 to 7 lac and arrange the amount upto 8 lac then which type of car (diggi wali) i can buy in this budget but remember i need good fuel average.

[capsat]

2002 onward model resaonable corolla can be sourced in that budget of 800,000

[SER_GTR]

A Proper Diagnosis Can rectify It If You Do Open And Close Engine Down Precisely

If Compression Are Strong But Oil Issue Is There...Its A Damn Dead Valve Seal And Oil Ring Stuck Clogged

If You Think Someone cannot Do...You Better Sell It And Get Something Better By Checking Issues Before Buying

Mostly Corolla's Do Face These Issue After 100,000 Km Due To Bad Oil/High Viscosity /Long Oil Changes ..Their Oil Ring Stuck Clogging Holes Making Oil Go And Burn Passing Compression Rings

[pwuser147983858371]

My corolla altis 1zzfe 2007 1.8 when it showed 325000kms on odometer started to reduce 1L oil after 5000kms and it was valve seals not more than this. But rings and pistons were still good and engine had 165 compression on all cylinders

[SER_GTR]

A Regular Oil change And Using Good Oil/ Filter Change will prevent this from happening

[rockstar.mij]

Brother I have 4efe engine under the hood of my 86 corolla...I am using caltax havoline 20 50..when should I change the oil? After 30k?
I have also done ring plus valve seal job last year 10jan..engine is perfectly fine..even silencer is clean...and should I shift to 10...40?

[pwuser149294234830]

@rockstar.mij

brother when i was using 4-EFE engine in my 84 corolla i mostly used to change oil after 2500km.

[pwuser149294234830]

@SER_GTR

I always change oil/filter on time.

[mujtabaayan1]

how to diagnose if O2 sensor is working properly or not on 5a-fe. I have disconnected the O2 sensor but there is no error code. Please help.

[SER_GTR]

reset ecu and check again...old toyota ecu are dumb and act stupid sometimes...you need to test voltage values using DMM to make sure its working....

[mujtabaayan]

I have already reset the ecu by removing the battery terminal but it had on impact. I have tested the voltage through multimeter both at diagnostic port and on the output of O2 sensor and it varies from 0.1 volts to 0.3 volts max.

[SER_GTR]

It Shld Vary From 0.1V To 0.9V But Thats When You Remove And Bench test It

Installing In Car It Remain Around Same...A Dying O2 Sensor Will Drop And Raise Voltage Slowly.

Salaam
I switched my car on cng and i am satisfied with its mileage as i am getting up to 200+ km in 55 kg one tank on long.

This car was Automatic and converted to Manual by previous owner

Now i want to convert my car from Manual to Automatic gears because I am facing some disk slip problem and due to this i feel lot of pain in my left leg and can't use clutch frequently.

Please guide me that it will be good or not on cng because petrol average is not good as i mentioned already and how much it will cost and which parts are going to change like Gear,computer and wiring etc.

Engine of my car is 4AFE 1.6

Thanks
