Overheating and no VTEC...WTF???
 

my car was overheating so i changed the oil pump (renr's) with another used one (the one that came with the block, beau's)

now it doesnt overheat as much but its still up there and for some damn reason my vtec doesnt work but it gets the 12v input
(vtec hasnt worked since i put the new y8 block in).

i bought this block a while ago from beau, so if u remember what could have been wrong with it, it woulb be greatly appreciated

check oil pressure, check all oil galleries, clean vtec oil screen

Re:Overheating and no VTEC...WTF???
 

before vtec comes on it has to have 55 psi of oil pressure..though the ecu...

check that screen on your solonoid, could be plugged.

if its overheating it will not go into vtec. so you need to solve that before you can fix VTEC.

I agree.. you need to fix that over heating.. are you sure you got the engine temp sensor wired correctly??

is your rad fan coming on at all??
