[capsat]

time to overhaul the engine sir @ahmad.25jadoon

@ser_gtr can guide for precautions when doing parts shopping

[ahmad.25jadoon]

What you suggest can i over haul my engine as original parts is difficult to source out as most Chinese brands are available in market or simply changed the assembly the assembly with kabli one

[ahmad.25jadoon]

On wet test Compression will incraese for healty engine ?

[Hassan1991]

Dry is fine.
Do wet test as well.
Share the pictures of pcv valve as well.

[ahmad.25jadoon]

i have done both test dry and wet both .
results = 150 psi for all cylinders in both tests.

[ahmad.25jadoon]

i have cleaned my PCV valve from both ends yesterday . After that i drive car almost 60km. Now you see the picture of PCV valve with clear deposit of oil on PCV valve. Oil deposit found on the end of PCV valve is connected on pipe side.

Indus produced Corolla equipped with 4AFE as 1.6 GLi Automatic
you can buy new engine rebuild parts at reasonable price. select a workshop from PakWheels member recommendations in your area.

Rebuilding will save your money for engine number endorsement on regn papers, required to keep vehicle road legal.

[Hassan1991]

Compression is not bad.
Be sure again pcv is ok.
After that try to look at the oil leakage from intake valves.

[ahmad.25jadoon]

@Hassan1991 kindly guide me regarding wet Compression . Is the Compression of the engine should be increase during wet test ?

As after wet test results @capsat recommend me for engine overall because in my case wet test result is same as dry test .

[capsat]

Compression is not bad

sir wet & dry values are identical perhaps it is at border line for value of 9.5:1 compression ratio for 4AF-E

[Hassan1991]

Agreed, it is on the low side.
@ahmad.25jadoon if wet test increases the pressure it means rings are weak.

[ahmad.25jadoon]

It means i need to over haul the engine ... Only changing rings is not a solution.....

[SER_GTR]

weak engine.....

you may need to rebore with .25 over sized piston(if standard) with head rebuilt and all lower crank bearings done with all necessary rebuild stuff..

get estimate of parts labour to further proceed....finding all parts seals of good quanlity is most important along with good machinist who can do it as per specs...not just with their knowledge

[sardarg]

for khi jamil autoz mr.irshad ahmed 0300 223 7538 is reputed name. please sir ask him for dry & wet compression test once again to be sure.

[ahmad.25jadoon]

Yes now piston size is standard

I am in Abbottabad

[ahmad.25jadoon]

@Hassan1991 @capsat. My car (EE100) has originally 2E engine . I swapped 2E engine with 4afe almost 3 years ago. Now is it possible to swap 1NZfe with 4afe engine without alterations ? What other things i need to changed with 1nz-fe ?

[Hassan1991]

1nzfe cost 300-350k and swapping will be another daunting task. Because no one knows how to wire it up properly.
It's better to rebuild the current motor.

[capsat]

rebuilding the engine is more economical then swap.
if there is automotive workshop in your area which can do the job under your instructions it is best. You need to spare the time and supervise everything yourself.

also please visit Toyota abbotabad and seek an approximate estimate for engine overhaul charges. without parts., get it in writing.
