Hey, just put a new rb20 in my r32. Its running a HKS2530, 5500ccinj, microtech etc. was driving it hard the other night, and noticed i could hear a very loud "ticking" sound from under the bonnet.
i pulled over and checkd under the bonnet, and it sounded like a lifter on the intake side. whilst idling at 1000rpm, the red oil light would come on, revs drop, then go off, and revs pick up. it would repeat this.
the standard oil pressure guage also reads very low. I am pretty sure my last engine died of the same symptoms, would blocked turbo lines cause this? Anyone got any ideas?
