Title: Stubborn Manifold Bolts
Post by: TandocTools on November 09, 2010, 10:24:31 am
These two manifold bolts are at such a funny angle in relationship to the intake opening that I can't get any sockets in there to turn them.  Am I missing something?  The bolt between the EGR valve and runner is so tight, I can't even get a box wrench in there.  I bought EZ-Outs, but the drill is at the same whack angle so that I can't even drill into the bolt squarely.  Is a simple breaker bar with a pivot what I need?
Thanks for looking!

swivel or universal joint adapter

these come in handy, but not sure if they'll work for this situation.

Those are pretty cool!  I'll look around the parts store for a swivel or universal that might clear, if not--I might give those Proforms a try!  Thanks!

I just use an open end wrench.

 I can't even get my Craftsman box wrench in the gap between the EGR and the runner.  I can get a box wrench on the other one, but I can't turn it.

For the one you can get to with a box end wrench you could find some suitable cheater bar to slip over the wrench.  Remember: lefty loosey, righty tighty.   ;)

Get a junk wrench and grind the box end down until it will fit

Got it!  I went to Sears and got the 1/2" short swivel for $8.99 and a $3.99 3/8" extension and it was off five minutes later!  Thanks for all your excellent suggestions!

1/4" drive swivel sockets and an offset wrench usually does it. Cleaning away all the crud helps too.
