Correct Torque Spec for the Side Cover on a 79 2F Engine (1 Viewer)

[1979 FJ40ish]

I've gone through all my manuals and checked the torque listing in the FAQ but didn't find a spec listed for the engine side cover.

Does anyone now what the correct spec is?

Thanks

I couldn't find any torque specs specific to the valve lifter cover either?

Here are some like specs....

Timing gear cover 10mm bolts....12-17ft-lbs
Oil pan... 53-104 in-lb

Those torque specs are in the 3FE Factory Service Manual; 91 inch-pounds if memory serves. Many people way over tighten those bolts, which squeezes the cork gasket away from the sealing surface and makes it leak.

I did 84 in lbs or 7 ft lbs... it still tried to squeeze the side cover gasket out in places. I found that spec somewhere here on Mud - didn't just pull it from where the sun don't shine and I'd say it's right based on the "squeeze out".

FSM doesn't specify as far as I know, but contains the standard torque specs. Here's some pics.

I used 90 inch lbs and split the gasket. Had to do over. Used 35 with good results. Also used some Toyota FIPG (thin coat) on the bottom half.

Thanks everyone. I was able to find this in the 3FE Engine Service Manual

Make sure you use a sealer on the bottom half

Side cover gasket....



This is where your Gasgacinch or Caterpillar 5H-2471 Green cement come in and shine...clean the cover and the sealing surface of the block very well agian with brake cleaner or other fast evap. solvent. Use some contact cement on the gasket and cover, attching your gasket to it. After the gasket has set up on the cover, I use just a bit of black sealant on the lower half, just to help keep things leak free. (sorry about the crappy first pic)


Hope this helps!

This brings up an interesting dilemma... Since I have already installed my side cover at more than double the apparently recommended torque (84in lbs vs. 35), should I back off of those bolts and re-torque? I could see that not working out as the gasket might not decompress enough to fill the additional space created between cover and mating surface.

Thoughts?

Leave it alone.



When it starts leaking again in a few years, address it then.

Thanks Poser - Any thoughts on how long these gaskets usually last before breaking down and leaking?

 

[Poser]

A long time, properly installed. Not properly installed? A few months or days...

Hell, I couldn't remember either knew wasn't much.
