yes thats the site but i dont know if im supposed to unscrew the fitting in the head or just pop the hose off!! i took the hose off and its just a nipple with a clamp on it!! and that site kicks buttt!!! hey rawilliams do u know of neone looking to sell a hx30 40 or s300 im startin to think its the turbo

 

I have a feeling the restrictor was removed on 99+ trucks for more heatercore flow. I know my rig is pretty chilly come winter. If you remove the hose, and look down the nipple you should be able to see a restrictor if there is one.

I can't say that I know of anyone selling a HX35, 40, or S300 at this time. You can always put a post in the Wanted To Buy thread.

How about the other side of you air system, the dirty side. Manifold to turbo flange gasket and bolts? Manifold to head gaskets and bolts? When I bought my truck I noticed a bolt fell out from the #6 exhaust manifold flange.

 

i checked every bolt to the manual that i could find!!! i have to change the vp44 tomorrow not enough time today!! but i guess ill git to see some more lines while its off..... i did take the cai off to tryin watch the impeller but couldnt rilly see it due to it spinnin soo damn fast but it becomes really noticeable when its around 1500rpm

 

Similar issue here. Anyone know of the fix before I go tearing into it?

Thanks

 

I installed a new BHAF air filter on my Cummins and now I have a slight whistle too. I think It is finally getting enough air to Boogie.
