7AFE swapped into corolla 1998

[SER_GTR]

Hmm My steering is leaking a bit and noisy so i am thinking of replacing it. The Electrohydrolic one motor is fitted in the column or in the rack? Steering in a good condition I am getting for 6500Rs very neat peace.

If the electronic one comes with Rack than i will straight go for electronic one.

Zulfiqar bhai i got that big Bosch alternator in my 7A.

That's Your Steering Pump Right There Sounding....!! Leaking What?? Rack Leaking Or Lines....!!!

@Xulfi Bhai...Yaar Tell Us About Replacing Rack Seals....Most Of Times Rack Got Leak And People Prefer To Replace Them With Another 2nd Hand Kabli Type......!! I Wonder What If We Replace Seals And Make It Work.....There Must Be No Rocket Science Involved Beside Precise Sizes And Perfect Seals...

Even MEchanic Keep Scaring And Saying "" There Are 95% Chances It Will Leak If You Put On Seals...So U Have No Other Chance Rather Than Saying..."Yea B**** Do Whatever U Wanna Do But Make It Work All Good "

^^ Same issue I am facing. The Driving side seal is leaking of my Steering RACK plus its making noise on bumpy roads so replacement is the only option. As the replacement of these seal they say dont work.

I use to have a very soft steering but I had a pipe leak and all oil got leaked I was with family coming home So I drove the car without Power Steering oil for like 5 KM after that the steering is hard and pump is also making bit of noise.

The seals can be easily replaced, just remove the rack ends and replace them - the reason they leak is that mechanics try to lever it out with a screwdriver which scratches the rack. The correct technique is to use two screws and screw them into the seal body and pull out the seal very gently. When putting it back in the seal spring cavity is filled with vaseline to prevent the spring from popping out on installation.

When proper mechanics rebuild the rack they remove the valve body first then the rack then the seals - install in reverse.

@ sinner - the electrohydraulic pump is mounted to the body on its own bracket which has rubber shoes to isolate humming, its connected like a rack is connected except that the rack has a motion sensor on it. It switches the motor on and off via the little brain box. That little brain box also has speed signal to eliminate assist at high speed.

I Will Give It A Try...I Was Wondering Same...They Might Have Scratch The Polished Side Using Improper Tools...!

The Only Way They Rebuild It Was When Rack Is Not Available And That's Also On Your Own Risk...

VSS Signal To Brain Box = Safety

W/O Brain Box...You Are Good To Be Dead On High Speeds...!

Driving W/o Oil Is A Big NO Specially For Oil Pump.........!! The Noise Will Be There Even If Wrong Oil Is Poured Which Mostly Happens...

you said you get around 170-180kms per cng tank on this engine. i have a 2E which i want to replace. i would like more power but also economy, enough so that i can get from Peshawar to Islamabad on one tank full. i was looking at 7afe but it doesnt seem to fit that requirement. would a 4afe be better choice then?
anyone having 4afe let me know about its cng consumtion so i can decide.!

GO for 5AFE than. Though I had 5AFE before and my 7AFE gives me better average on CNG than 5AFE. Reason you dont have to push it too much to get it goin.

5AFE its a good engine. Powerful enough and gives good economy.

[salal777]

am kinda confused abit now. if 7afe gives better average on cng and also has more power, then shouldnt i go for it instead of 5afe? i take it from ur reply that 5afe will b less efficient. clear me up if u dnt mind.

[Vaqas1]

To be honest I tried all 3 Engines. 7AFE and 5AFE in my car and 4AFE was in brother's charade they all give identical fuel economy all three are designed for economy.. 7AFE and 4AFe are identical interms of power but 7AFE got better low end torque or we call it pick. 5AFE is weaker interms of power then these 2 but its still at least 50% more powerful than your 2E :).

So its upto you if you want more power 7AFE gives you good low end torque.

BTW If you swap please please make sure you buy an engine with completely uncut wiring which is some time hard to find in Peshawar.

[salal777]

that low end torqu/PICK is what i've been longing for for a looong time 1.5 maybe good but its the 4/7afe which i wnted to decide between. good info on your part. i was thinking about 7afe the most out of all 3 so i think i will get it.
and about the wiring, yes thats 1 thing i have been hearing from everyone so i will look for the uncut

[salal777]

i also read somewhere that there are 2 varients of this engine. 1 with distributer another with coil system. and some say distributer is better for cng while others say the coil type is better suited for cng. can you shed some light on this?

[Vaqas1]

Distributor one will be more suited for CNG but if you can afford a LR original Advancer that costs around 6500Rs which people dont install than the distributer less will also work fine on CNG. BTW Distributor one is also more powerful.

One more thing that will confuse you more is 7A had one known issue if you search online the first gen the distributor one had this oil burning issue which was solved by toyota in 2nd gen distributer less. So make sure the guy you buy engine from gives you proper guarantee of one month as few of these distributor ones burn oil.

[SER_GTR]

Go For 7A If You Can Find....Else 5AFE....!!

7AFE Is Preffered Bcz Of Its Low END Torque....!!

[salal777]

im opting for the 2nd gen distributor less since its the newest after the 1st one. and i hear that its cheap too. since the early distributor1 has more power it will also have more consumption than 2nd gen. meaning the 2nd gen will be more efficient while still having good enough power, which in turn makes it a good choice for me

[Vaqas1]

Yes distributor less one is more economical. Its also has Lean Burn function.

[SER_GTR]

LEAN BURN If You ARe Using it On Petrol....!!

[Vaqas1]

LEAN BURN If You ARe Using it On Petrol....!!

Yes Yes. CNG per its already very lean and dry that your plugs turn white and valve seat burn

[salal777]

LEAN BURN If You ARe Using it On Petrol....!!

i thought it was settled that the engine with that function was better for me since i will be using cng not petrol ?!?!
or do u mean something els

[SER_GTR]

ALmost No Use Of That On CNG....It Won't Be Working As LEan Burn Then......So Get A Regular Type....
