Replacing the intake manifold gasket on the 04 Corolla. The Haynes manual says torque to 22 ft lbs. Online I find 14 ft lbs. The block is aluminum so 22 seems high for a bolt, seeing as the spark plugs are 14 ft lbs. Any one know for sure.
I compromised and tightened them to 17 ft lbs.
No more PO171 code anyway.

Thanks Bud. Yes I got the updated orange one from the dealer.
I will loosen all fittings and retorque to 14 ft lbs.
Hope I didn't cause any thread damage, it's got a days driving on the slight overtorque.

lol I have never torqued those down to spec, just tight enough with a long ratchet, I have never had any issues with them.

You can never go wrong torque to spec as long as your torque wrench is accurate.

I guess I never did torque the intake manifold to spec because when I was using the OEM Toyota service manual it wasn't listed in the Cylinder Head Reassembly section

30Nm -22 ft lbs Per Alldata

Those are nuts that go on the studs right? You are not putting much strain on the threads in the head.

2 are nuts on studs yet 4 are steel bolts that anchor into the aluminum block.
Thanks Trav

Too late for that!! The gasket is already compressed to 17 ft lbs. If you loosen it up and re-torque it too 14 ft lbs, you run the risk of getting a vacuum leak.

Probably to late now, but I'd just leave it as you did the first time. It'll be fine.

OK, I slightly backed off the fasteners and retorqued to 15.5 ft lbs that's where I'll leave it. The updated gasket is silicone so it will seal better than the original rubber gasket.
Thanks guys, if there is a Heaven there is probably an express line at the gates for BITOG'ers
