check your intercooler piping, a coupler may have came loose

For the 9 or so years that I have been reading posts on forums, this is the new record holder for longest run-on sentence. I mean seriously, did you text this post in from your phone or something?!  -Check the pressure lines to the EBC too. -What are the plugs gapped at? -The loud ticking you heard upon startup is probably just your lifters don't worry about it. It goes away after a few seconds right? -Does the click on the left side of the motor cause anything to happen to the idle or engine tone? It isn't the injector harness grounding out somewhere is it? -The coolant is rusty because your engine is about 15 years old and has probably sat in a junkyard for the previous 5 years. It takes a while for the rusty crap to come out of the block. My coolant is still turning a little rusty even after I rebuilt the motor.

what can i say i just rock with sentences hahaha but yeah i have checked the lines leading to the ebc i think i might have a boost leak but with all my searching and tightning of every clamp! none seem to be leaking but while i was driving yesterday it sounded like i was boosting but my boost still showed a negative vacume and i felt no boost so im sure there has to be a leak of some kind? the clicking noise does not affect the tone. how could i check to see if the injector harness is grounding out

If your sprayed your intercooler piping etc that wouldnt really affect ur rpms. I think you gotta spray your vacum lines for that trick to work.

if you were spraying Carb cleaner on areas of possible vaccume/boost leaks, it would actually raise the idle due to the combustible fluid that it contains.

Yea i know but I thought he meant he sprayed like the pipes going into the intercooler and coming out. Isn't that always pressurized? It wouldn't be sucking air in through there though.

Did you do your swap? If so, I have a RB25 sitting in my garage. Maybe you could help with some pointers.
