I read on JK's website that after you drill and tap for the boost gage install, you should change your oil right away afterwards. What about if you take the intercooler pipe off completely, have a buddy weld a bung on, then clean out the inside of the pipe well before reinstalling? Seems like it could be easy enough to do that way instead.


I guess I don't know enough to know why to change the oil soon afterwards anyway, please educate me (sorry if this has been covered before).


Thanks,

either I don't understand, or that doesn't make any sense!?


If you're installing a pre-turbo pyrometer - why would that have any effect on the engine oil?

corona,


That's what I was thinking. I wasn't planning on getting anything in the pipe since I was going to take it off completely. Maybe I'm just retarded (easy, Diesel Power, easy). Here's a clip from his site:


Boost Sensor Installation

I prefer, whenever possible to plumb the boost gauge to a solid part of the engine. On the 2002 and 2003 models, the casting that feeds the intake (from the intercooler) and houses the boost sensor and intake heater is long enough to provide a simple installation. I drill and tap to 1/8” NPT. To do this, I remove the intercooler hose and insert a shop vac hose to draw out any chips as they are produced. It is also not a bad idea to change the oil shortly after doing this. The alternative is to cut and tee into the wastegate hose. This is a simpler operation, but does not provide a firm mount.



The directions on his site were awesome and the hoot method worked great, I am just going to rewire everything a little cleaner now when I get a part or two in.


Thanks,
Dennis

i think JK's reasoning behind the oil change is if you didn't quite get all the aluminum chips out of the intake, they could contaminate your oil and if you were doing oil samplings, it would/could read high for the aluminum after being run for a while with some chips going through the combustion process...

Okay, that makes some sense now. I guess I just didn't think that if the chip made it into the cylinder, that much would happen to it. Kind of like passing dirt or something.
