Bolt size for rocker arm assembly?
 

Hey guys, had oil on the spark plugs so I replaced the valve cover gaskets and tube seals under the rocker arm assembly. upon reassembly I over torqued a bolt using this guys "how to" and broke a bolt. He gave the wrong torque specs so now i gotta extract the bolt some how. Anybody know the size and length of these bolts? cant seem to find the specs any where using google. thanks guys

which bolt broke off?

If you count from left to right its the 4th one middle Row and the one directly below it, bottom row not the 10mm on the rocker arm itself but the 12 mm ones. Need a part# or place to get them from thanks man

Best place to get a replacement is a Honda parts outlet. Bolts from auto shops are frequently lower grade bolt which can also cause problems.

The smaller bolts are 6x1 mm (10mm socket size 8.7 ft-lbs torque spec) and larger are 8x1.25mm (12mm socket size 16 ft-lb torque spec).

Did you use larger bolt torque spec on smaller bolt?

good luck

If you watch the video i posted above I was misinformed on the torque spec. Instead of 16ft-lb i used 22...I will no longer trust youtube for a DIY after this. Im still looking for a part# as the Honda outlet website im using doesnt have the bolts in the diagram. Thank you TexasHonda for your reply

Not sure on the year of your accord (I put in 95 LX for my search on hondapartsnow site)

The OEM part number is 90007-PT0-000

It is under cylinder head. I'd call you local dealership, the part would be less than five dollars.

Laughing because I did the same exact thing on the same engine once. I still remember the feeling of dread when it snapped. What I ended up doing was getting the bolt from a Honda parts website. Like TexasHonda said I would just go that route. You're not going to find a better or even suitable match I think anywhere else. The bolts are what less than <2.00 a piece. Admittedly the shipping will probably kill you but that's still less than $20.00 for peace of mind.

To remove the broken bolt what I did was:
1. Bought left-hand drill bits at Autozone.
2. As straight as possible drill in forward (not reverse) using the left-hand drill bit. Choose a bit size not too small but not too large to avoid hitting the aluminum walls of the hole. Maybe half in diameter.
3. As you drill in with the left-hand bit in forward it will bite into the broken bolt while imparting a reverse on the broken bolt since the broken bolt threads in the opposite direction.
4. Since you broke it overtorquing it should spin out with no effort since the top half of the bolt broke off there's no longer any clamping force hold the broken bit in. When I did this and got the broken bit out I noticed the drill bit barely dug in, it spun out that easily.
5. Once it reaches the top of the threads you'll need to fashion something to fish the now loose piece out. I used bubble gum on the end of a toothpick. :shrug: I would have used one of the wands with the magnet on the end but the hole was too small. You might be able to on the bolts in the middle that look larger.

I used this set:

And I recommend the bit second from the right.
