The intake side exhaust stud, 2nd from the right.... I couldnt get my arp stud to thread for some reason. It didnt thread down like all the other studs. It would fall half way through, and you would have to thread the stud in, and after twisting it 15~ times, it would drop 1/4 inch, and I couldn't thread it into the block, I tried a different stud, I moved it at every angle I could, nothing. So I decided to re use the stock stud, without torquing it =/ My torque wrench is 1/2" and I only had the one socket for the arp nuts. HG leaking, and before looking in the radiator to confirm it, I heard an exhaust leak coming from under the intake manifold, which is where that stock head stud is, honestly I think if I went back in and torque is to 80ftlbs I would be fine but I don't think that is safe/smart and I'm not sure if thats bright for a stock stud.


I have my work cut out for me this weekend, just gonna remove the goddamn head like I should have.

This was the first time ripping out any cams, on any car, and even though this failed, I'm happy I was successful reinstall the cams and getting the timing right (I didnt remove the crank pulley)


So pretty much when I do the HG, I gotta remove the crank pulley, timing belt, and thats it huh? (n make sure to mark the pulley, and block. I'll leave the IM and EM on until I completely take the head off, unless theres an easier way. I have never changed a HG so this will be another first. I will have the head surfaced when I pull it out. Should I clean up the top of the pistons and block while I have it ripped out?

Ugh I was looking forward to upping my boost tomorrow but thats a no go!

 

Oof anytime you have threading trouble like that usually means they are F'd up which is way worse than the HG leaking. Honestly I would try just torquing the stock head bolt and seeing if the HG seals. Its not any worse than you've already done...

Did any of the thread material come out on the head stud or bolt when you removed it? It sounds like its gulled or really dirty.

 

I didnt want to hear that, ****, guess I gotta try it. Should I torque it to the 75lbs that all the other studs are at?

No material came out, the bolt was clean.

 

Remove the head and clean the threads up with the proper size tap. This should be done anyways so you can correctly torque the headstuds in. It doesn't take much to booger threads up. Hope its good news and not bad when you get it back together.

 

If this is this first time taking the head off remember to take the coolant plug in the block out (right under the exhaust studs) if you don't you'll have water in your cylinders..

 

Thanks, me too. I think i'll do fine.

 

Which exhaust studs, head studs, manifold studs? I'm not familiar with this plug. Can you supply a pic? Thanks

 

You should see it on the block facing the front of the car. Its probably like a 19 or 21mm.

 

ah ok. I thought it was an external plug. Thanks

 

It is, look on your block to the left/behind your header, its the big plug

 

you probably have oil in the thread holes and it's not allowing the stud to thread all the way down....you need to be careful or you could damage the threads.

you are better off removing the head and doing it right the first time.....

 

 

This is exactly what i was thinking....if you put to much oil on that thread and its puddled up on the bottom then its not going to allow the Head stud to bottom out. Basically as you screw it in its going to compress the oil and it will feel like its bottomed out. IF no shavings came out and its screwing in fine until halfway down that def could be youre issue

Get a straw and suck that oil out of that thread youre having issues with. It could have even filled with coolant or oil? who knows just makes sure there empty of fluid

 

thanks for the help yall. pulled the head in about an hour. Thanks for the tip with the 19mm bolt

Also, after pulling the head, the troubled head stud went right in without issues, WTF!

I noticed these little bearings came out from a few head studs, where do these go?

 

Little bearings? You need to post pictures ASAP, before you continue.

 

 

Those are dowel pins they go in the block in the top left corner in the pic

 

and on the other side as well?

 

 

Make sure you replace with a NEW head gasket...... sounds like you're a "first timer", head gaskets are not reusable (with minor exception).

 

No, they go on the outermost head studs.

 

so 4 total?

 

There are only 2 dowel pins that you will need. They go over the headstuds on the outside studs at the front of the engine.

 

may be the first time pulling a head but I'm not an idiot

 

just want to be 100% certain. The studs circled in blue?

Thanks.
