Hi, firstly forgive me if this is in the wrong place!
i am currently replacing head gaskets but cannot seem to find solid information on torque specs for the head, I have a my97 Ej20g and the manuals that I can find are always missing my year out.
The 1993-1996 manual I have specifies tightening all bolts to 29Nm then 69Nm, back off 180 x2, 29Nm then 90°, then 45° Then bolts 1 and 2 a further 45°.
The sheet supplied with the gasket that is listed as fitting years 94-99 specify tightening 29Nm then 69Nm, back off 180 x2, bolts A & B to 34Nm, C,D,E,F to 15Nm, all bolts 90°, all bolts further 90°.
Can anyone advise which spec they have used with success? As I have read on Nasioc that the second set of instructions I have listed are for a sohc engine and that I should be using something closer to the first method - the info there was pulled from an 04 sti manual and one number does conflict with my “93-96” numbers that being 49Nm rather than 29Nm but the tightening off all bolts to a single torque is the same - link for reference just in case I’m confusing you - https://forums.nasioc.com/forums/showthread.php?t=1780049
Pictures of 93-96 manual also attached for reference
Any help would be massively appreciated!!
Cheers
Jake
