Took my rig in for a RWC today. Went in to pick up car seen on the sheet, " Remove blow off valve".
Im thinking hmm, what the hell. Any way let the mechanic run through the list and then he got to the BOV and I go mate its a factory BOV, it recirculates, nothing is released into the atmosphere. Should have seen the look on his face, priceless. He soon crossed it off the list. It has Nissan on it and a part number, same type of casting/colour/make as inlet pipe. Moron..
The other good one was my intermediate/middle muffler was less than 10mm to low. The clearance is supposed to be 100mm and we got it to 115mm, When I say we my mate runs his own exhaust shop. The mechanic said to fix it just put a jack under it and jack it up. Yeh right mate...
