Replacing head bolts

[97fortieth4me]

Did any of you guys replace the head bolts when you did your HG?

Is it recommended? I was planning on it anyway, but I was just wondering if any of you did replace them.

We should have the head out by tonight, and off to the machine shop tomorrow, hopefully.

Wasted money (price the Toyota bolts before casually saying you're going to replace these...). They're fine for reuse and there's a spec in the FSM for measuring them before reusing.

Thanks for the reply Doug!

I just got a price check on them. Looks like they're about $10+ each, there are 14(?) bolts.

I think I'll reuse the old ones.

unless LC's are different, it's never been recommended to re-use headbolts on 4Runners or mini-trucks. And particularly, on the mini trucks, the 22R/RE headbolts tend to get full of carbon, gunk, and even oil, and they tend to stretch.

At a bare minimum, make sure to chase the threads in the block and on the bolts, clean out the holes perfectly clean, and put just a tiny bit of lightweight oil on the bolt threads for reinsertion. Don't put loads of oil on the threads, or it will fill up in the holes and cause the bolts to falsely bottom out (oil doesn't compress).

I don't know if ARP makes a kit for the LC, but they do make a reusable stud kit for the 4Runner/pickup engines. Might be worth a look.
