Topic: No boost reading (0 PSI) and code P0106

[TomatoSoup]

Yesterday I discovered I was getting a solid 0 PSI boost display on the DIC, but the car seemed to run and accelerate fine.  I thought it might be "one of those things" but it remained over a couple of engine off cycles, so today I plugged in my cheap Sears OBD reader and saw it had thrown a P0106 code.

So looked under the hood and found the intake hose bulging and not properly seated in the (T-bolt) clamp at the rear of the driver-side intake tube. So I loosened the clamp, reseated the hose and tightened again.  Cleared the code and drove it - all now seems fine.
 
Bottom line, I must not have tightened the clamp properly when I replaced the factory clamps - I was very wary of over-tightening in case I crushed the intake tube.  Anyone give me an idea of how tight is 'enough'?

Stop just before you crush the tube  -  sorry couldn't resist 

[TomatoSoup]

Yeah... err... thanks.

It's about a 2-grunt with a 1/4" drive.  Slightly less than a grunt if you're using 3/8" drive (well, depending on how long your ratchet handle is)

Thanks, but I'd prefer if we kept my ratchet handle out of this!

between 6 and 9 inch - pounds that is,   I got to stop this 

Okay straight face and being serious.  Military term grunt torque.  One grunt - tighten until it is tight and then one grunt more.

tight is tight, too tight is loose again

Tighten it until the tube crushes or the bolt shears then back it off a quarter turn.

GJ is on his way to Hellinois so it may be some time before he chimes in.  Moby, its your turn.

Roger that ESAY, this is Moby.

I concur with everything Jiggle said in the third post after the post about the horse that got loose.

Over and out

Soup - I had the same question when I did my clamps this spring.  I went with "That seems tight enough" theory and blew off the same connection as you.  I asked and nobody new then either how tight to go, so I went with "One more turn and please God don't let this crush it".  Redid all the clamps that I originally wossied out on as well.  Cleared the code and haven't looked back!


See - I can actually stay on topic when I'm sober!!!

TS,

KWhale is right.  We all were a bit hesitant at first.  I have cranked mine down several times now.  I don't think there is any way we can actually crush the pipes.  The rubber will start to deform pretty good, but that should be ok.  I am still having P0101 issues and may try to tighten them up again.  I was able to break a clamp on purpose (I was testing to see how tight I could go) but it was with WAY more grunt than needed for these clamps.
