Hi Manuel, There are a number of different engines used in the Corolla, knowing which would be a great help. The engines used in the 1993 are of the 'A' series and 'E' series. The torque for the A series is 29 nm + 90 degrees. When removing the head begin loosening from the outer bolts. When the head is off have it inspected for warpage and skimmed if it is required. Tightening any cylinder head always begins at the middle or centre and works outwards. As my friend has said, the camshaft caps are tightened to 9 nm and the inlet manifold goes to 24 nm, and the exhaust is 27 nm. The tappet cover I think is 29 nm. The tappet cover is tightened on the A series with nuts onto the plug tubes. Regards John

Cylinder Head Bolt Step1- (25 FT.Lbs) Step2(45 Ft.Lbs) Step3(65Ft,Lbs).....Intake Manifold(35Ft Lbs)....Exhaust Manifold Center (20Ft Lbs) All Others (20 Ftlbs).....Thanks

Don't have a way to send a diagram. Calif. emissions and 4wd vehicles is 10 degrees BTDC @ 800 rpm. Federal emissions is 10 degrees BTDC @ 700 rpm. Hope this helps.

what is the torque specs on 4afe 1.6 toyota corolla connecting rod & cylinder head

EGR stands for EXHAUST GAS RECIRCULATION.

This is a loop back system between your exhaust manifold and the underside of your filter.

The EGR valve is located between the inlet (exhaust manifold) and the outlet (intake manifold).


About 8-12" below the air filter....toward the passenger side.


EGR carbon built up can be clean.

Check the soft membrane on the EGR valve and see is it crack/torn. If it's in good shape then you may reuse it.

The professional use a vacuum hand tool to determine the travel of the EGR.

There are carbon built up inside the EGR air passage tube too,


Make sure you give both a good cleaning.


The EGR base gasket MUST BE REPLACE!


Order one before you start the job.


Please post more info on the comment window.

remove the exhaust manifold with a 14mm. socket and pull off old gasket, may have to be scraped, install new and torque bolts to 33 FT. LBS......... same with intake manifold but 10mm. and 12 FT. LBS of torque and drain coolant.
