hey guys im in the process of putting on the GMPP manifold, but am having a very hard time getting the stock nut-bolt out of the flex pipe flange and the stock manifold. for those who have taken off the stock manifold is there a trick to doing this. i have gotten nut off, pulled one stud out, and can not get the 3rd one to budge. i have soaked them with PB blaster, but the just get harder to turn the further they come out. please help and Merry Christmas!

 

I had this problem in a my truck before. I went out and bought a cheap socket that was in Metric size, and a smidge too small. Then I hammered it onto the nut.
If you've got a socket wrench that wont snap( Or I just used a monkey wrench, since the socket was gone anyway.), and enough leverage, it'll either come off or snap the head off. If the second one happens, it wasn't going to come out anyway.

Then again I may have what you described completely wrong in my head, In that case, just ignore me like everybody else does. Good luck!

 

yeah thanks man but im not going to do that haha

 

Yes the secret is... get a friend who can bench a fair amount (250+) and have him break that bitch loose. A buddy of mine who can bench 275 got under there, and practically lifted the motor out of the car, then BOOM the bolt broke loose. Thats after 2 straight days of being soaked in WD-40.

 

damn looks like i need a longer wrench... my dad is pretty damn strong and he was lifting himself off the ground trying to get it out

 

NO NO NO!!! Get underneith it on your back, push up on the bolt so your pushing your back against the ground.

 

i dont see how thats possible because its the top one!

 

and did the 9 studs coming out of the face of the manifold come out any easier?

 

Yeah, the only ones that gave me trouble, were on the collector of the manifold. The bolts that go into the head wern't that difficult. The ones on the far driver side are a bitch because there is .00000001 square inches of room to work with

 

k any other advice besides raw strength guys?

 

Not that I can think of. If you need any more help PM me

 

god that brings back memories.....

wd40 and bloody nuckles (from trying so hard and then my hand flies into the block lol)
^^^ thats what did it for me.

try a torque wrench

 

how hard would it be to get a impact in there with say a swivel head, etc.?

 

i dont think an impact will be stong enough to be honest

 

PB Blaster works better than WD40. let that sit for 20 minutes and you should be ok.

 

I tried a MAPP gas torch on mine, didn't do ****
EDIT* Except ignite the WD-40 that was on it

 

Hey, stu, im no wuss , you could have gave me a shout.

 

thanks but thats what i said i tried, and it was on there for at least an hour

 

i wasnt going to bother you on Christmas man!

 

dude, in my opinion xmas is over by 1pm...lol anyways, did you get it off yet, or what. If you need anything give me a shout. I should be free all week.



btw- i believe the mods in your sig need to be updated.

 

not till i get times haha. my dad is bringing home some different tools today so we should get it off.

 

Cool, have you tried a breaker bar, or will it not fit in there?
