I'm installing a Motordyne 5/16 spacer and I've got evrything back lined up with all the bolts hand tight. I set my torque wrench to 40 lbs. The first bolt #1 on the instructions gets almost all the way tight and snaps! I took everything back apart and naturally it snapped flush with the lower plenum. any idea's on how to get it out? Has anyone had problems with these bolts in the past? I double checked the torque wrench and it was set for 40 lbs. But I use in on my lug nuts. What should I use for a replacement bolt.
My first major mod and its gone bad...

try callin motordyne... they may have a solution.. i bet it has happened before... the only way i know is to drill it and use an easy out...

did you have it set to 40 inch pounds or foot pounds? it needs to be set to 40 INCH pounds

^ +1 and you shouldn't tighten any of them all the way until you've gone around tightening them in the correct order

Your right Kennymo. I'm such a f***ing idiot! It was set to 40 foot pounds not inchs. I was able to get the bolt out with a pair of needle nose pliers. Now I'm just wondering if I can use one of the old bolts until I get a replacement.

40 ft/lb will crack your plenum for sure

the bolt size on these torque requirement is 8.5 ft/lb for that size bolt - but usually they get tighten more than that - i found out that the factory tighten them around 18 ft/lb = scary

but i guess that's the way they do it so they don't have to retighten the bolts one they leave the factory

you can go back and set your torque wrench to 10 ft/lb or 12 Newton/m which ever your type of wrench preference setting your have is easier to set - you can use the old bolt until new ones come but since you cracked something i would go and epoxy that crack with metal type and wait for the new bolts rather than doing this again and again - but i think that 5/16 is very low so the old factory bolts should fit with not issue only that if is NOT AS GOOD as the md longer bolts

didn't anybody read about my blox spacer instruction thread in Gspot???

i specifically stated that 100 60 40 inch/lb conversion to 8 6 4 ft/lb or 12 8 6 N/m

since we're on the subject - a little common sense goes a long way

important car parts??? engine bolts etc need correct careful handling

not so fragile parts??? tires rims bumpers go ahead do as u please cause someone else will do it for u

i got a question. i know the 6 cents bolts on the plenum are longer (the ones you get when you buy a plenum spacer. ) but do the outside bolts need to be longer also? or will the stock ones work?

I know I know. The Plenum is fine, no cracks or anything and the bolt came out pretty easily. Motordyne is sending me a new bolt.

Loctite blue on bolts

I'm supprised this hasn't happned before, even though MotorDyne provides high quality hardware and instructions. It's their lack of knowledge on torq settings where members get in trouble. Torq wrenches come with instructions, I keep the two close.... Loctite "RED" on suspension parts....end links etc.

it has happened to tons of people. there are tons of threads about this happening
