RB26DETT Rebuilt engine nasty valve train noise on start up I just replaced the head gasket on this engine. I accidentally started the engine without priming it. After the start up, it immediately developed this nasty valve train noise. Does anyone know where is the noise originated from and how to fix it. Here is the you tube video: https://www.youtube.com/watch?v=51lzWDkK2nw

Is it possible that tight valve clearance on the exhaust side can cause little to no vacuum on idle...... This is regards to a RB25DET NEO i got...Re done the head installing tomei 1.2 head gasket and lapp over the valves however after that was done the intake side was at nissan specs of 0.012 and the exhaust is way tighter(0.014 to 0.015) on all 12 of the exhaust... will this cause such issue... secondly my last chance was to check to see if my timing was off Running tomei poncams 260 9.15 Intake and 262 9.15 Exhaust
