89 4runner. 22re engine.

Had block totally redone. Tanked, bored, etc. New cylinder head and head bolts from engnbldr.

Torquing the head bolts down, one of the bolts was "chattering" the last little bit I was torquing it down. I don't know why it was doing this since I had put a little engine oil on the threads and spun the bolts in by hand. No problems while I was doing that. The other bolts torqued down pretty smooth, but one didn't. Didn't like the feel of it.

Should have spun the bolts into the block first before installing the head. Hmmmmmm........

I know I'm gonna pull the head back off. Would rather do it now rather than wonder if it is going to hold together after I get the thing installed. Head gaskets are cheap.

Can I reuse the bolts? And, your thoughts appreciated why it was "chattering"? Thanks.

These are older pics, but this is the machine I'm working on.

I have had bolts "chatter" as I'm torquing them down if i have forgotten to lube the underside of the head of them where it contacts the cyl head.

 

like little tick tick tick as it was turning? sometimes bolts on my engine/suspension do that as i untighten them and tighten them

 

Here's a thread I think you ought to read. Save yourself some heartache later maybe.

That's a good read. Thanks for the link.

The link talks about "hydrolic lock" (or however you spell it).........I only put a small amount of oil on the threads and the block bolt holes were dry. Must be the liquid that's doing it, though.

Thanks again.

Tighten it till it strips then back it off a half turn......grandpa yous'ta say. But really it only take a few minutes to pull the head at the point your at.......and a once of precaution is worth a pound of cure!!!!!!! measure twice cut once......when in dout check it out. You know.

 

No kidding!! I was getting in a little bit of a hurry since I had to get to work, and, I just had to get the head on!! What a dumba$$. I almost came inside and typed on yotatech "ok, I'm just about ready to install the cylinder head.......last comments welcome" or something like that.

I thought to myself "self, how could anything possibly go wrong with this?"

Hind site is 20/20 anyone who has wrenched on there stuff has made that "ooopps why did I do that ? " the learning curve can be costly, better to play it safe then sorry.

 

i don't think that warrants pulling the head back off, so long as the bolt actually turned a similar amount to the others when you torqued them. if you were able to get lets say, 1/2 a turn total on the others, and 1/8 of a turn on just this one, that would warrant removing it. buy a tap and chase your threads, blow them out with compressed air if you do take it off. and remove the black stuff from the holes drilled in the head for the bolts. have fun.

 

hydro-lock would be caused by a LOT of crap down in the bolt holes. you're issue sounds like simple dry bolt. You DID have the washer on that one, right?!?

 

22RE engines do not have washers for the headbolts. Only the V6 engines do.

 

Washer? Man, I just about $#%&* my pants there!!

I"m going to call the machine shop, the guy who rebuilt my lower end today and see what he thinks. I also emailed Ted (bought all my top end stuff from him) to see if he would chime in on his thoughts.

Thanks again.

Yotatech is sorta like the Doctors office....ALWAYS get a second opinion if you aren't 100% sure. A lot of advice given on here isn't always 100% correct, though usually given with the best of intentions.

 

Grandma yous'ta say.........the road to hell is paved with good intentions.LOL the facts aren't always the facts , we all make mistake's. I thought I was wrong ONCE , but i was mistaken. ha ha . Just kidding . Its not easy being a jackass but I live with it.

 

Have you cranked the engine up since you put the head on or are you still putting it together?

 

I"ve got the engine in the engine stand.

Took the head back off. Sure enough, winding the bolt into the block, it bound up the last little bit. Guess the machinest forgot to clean that one up. And, it's my fault for not cleaning all of them up.

Going to get the right dies and such and get them all cleaned up. Got another head gasket coming for it since I won't be reusing the other one.

20 dollar mistake. oh well........learned something here.

Thanks Jim for posting the link to my probs. Mine was doing the same thing like you read in my post, After I cleaned out those holes its tightened down clean and torqued fine

 

Before I forget, coat head bolts with a light coat of engine oil, or something else? Thanks again.
