Hey guys, I was in the process of replacing my oil pan gasket for my d-16 and when I was putting the bolts back in and torquing things down I came across one bolt that will tighten and break loose. Did I strip the threads?
Options?

 

NotARacist posted about a stud kit for the D and B series oil pans. Same kit.

It can be had at http://myhondahabit.com/index.php/my...-stud-kit.html

If you contact them maybe you can get just the stud kit without the gasket being you don't need the b series gasket, just the studs. They work in either B or D series NotARacist mentioned.

 

Thanks but in this situation I am worried that I may have stripped the threads. I am kinda lost because I hand tightened everything then grabbed my torque wrench and it just kept turning.....

 

Exactly. Being you may have, the stud kit replaces the studs in the bottom of the block, thus also replaces the threads on the block. The nuts are a dime a dozen so that end doesn't matter. The biggest issue is the bolt studs.

You can always take the nut off the suspect stud and inspect both the stud and the nut. See which is stripped.

The stud kit is a stronger stud that you put in, like ARP head bolts or studs for the head. Much stronger than the OEM studs. Same thing. You basically unscrew the OEM studs from the block and put in the new stronger studs from the kit, then breaking/stripping is a thing of the past. Might strip a nut afterwords but like I mentioned, the nuts are a cheap thing to replace.

Unless.... the stud hole threads in the block are stripped. That would mean an oversize tap and an oversized stud and oversized nut.

Another possibility is the stud came loose when you were taking the nut off so will be tightening at the same time you are trying to tighten the nut. The studs unscrew counter-clockwise from the block just like the nuts do from the studs.

 

They sell the stud kit separate. I was looking around on there after reading the other post.

could always just tap and make it a little bigger.

 

Rather than going to an oversized stud, the better fix would be to use a helicoil. You might even be able to rent a helicoil tool from a NAPA store. That would at least keep you from having to drill a larger hole in the oil pan and have one oddball stud/nut combo.

 

Time out. There are words being thrown around incorrectly, and I have a strong feeling that we're not all talking about the same thing.

OP, you said a bolt keeps turning. Is it a bolt, or a nut on a stud? If it's a bolt, remove it and inspect it. If the bolt isn't damaged, then the block is, and you'll need to helicoil/timecert/retap the hole. While the stud kit is ******* awesome (no seriously, if you're replacing your oil pan gasket and not getting this stud kit, you're doing it wrong), it isn't going to fix a stripped block.

If it's the outside of the stud that's stripped, or if it's one of the many nuts, then yes, that kit will perfectly solve your issue.

 

Yeah, I tried to just re-tap the hole the same size as the bolt. No avail. I guess Il try a size up and hopefully that will work. I really don't want to have to drill into the block.

 

So you have bolts not studs?

Either way, helicoil will replace the stripped threads in the block and let you stick to stock size bolt or stud (whichever is your setup).

 

TomCat, about half of the pieces holding the oil pan in are studs, and the other half are bolts.

 

I am going to take a look at how the heli-coil works and maybe give it a try.
The two main things Im trying to avoid is drilling and taking the pan back off. Thanks guys.

 

Gotchya, I've already forgotten what mine looks like. The only part that comes to mind is the nuts by the transmission holding the inspection plate up. I've already forgotten all the rest of when I was retorquing my pan bolts and nuts. I can't seem to mentally visualize much of any of it.

Not that it is really important with the information the stripped portion is the threads in the block though. Doesn't really matter if the hole is for one of the few studs or for one of the bolts. It's either over size time or helicoil.

Good luck, I'm hoping it works out well for you ElswickB22.

 

Well good news, went out and got a tap one size up and a bigger bolt. Got it in and tightened to spec. Started it up and let it run until the fan kicked on and no leaks! Gonna let it cool down and go for a drive!
Thanks for all the help!
