hi too all
now that its summer here is australia my 1uz hilux is starting to ping on hot days where outside is about over 30 degrees celsius
what i do know is when im statinary for afew minutes stopped at a set of lights the engine must get abit of heat soak and as i drive on light throttle after that it pings its head of very badly sometimes
its a very strange problem becuase i cannot pin point a cure for it
there are a few things i think
1 fuel pressure is ok checked with gauge but metal lines from the efi intank pump are 6mm then just ater they exit the tank goto 8mm from efi fuel filter then 8mm to engine
i dont htink this is a prob but just wondering if with 6mm pipes maybe causing a fuel flow problem
2 Radiator not big enough thermo fan switch on and off ok so engine doesnt overheat i think but maybe the radiator which is std hilux one maybe does not flow enough water therfore the back of the engine gets hot
3 the hot air under bonnet is not expelled properly which i have put spacers under the back of bonnet didnt fix problem fully
it is annoyinh this problem because i dont know exactly what to do
if i could just replace or upgrade a part then its easy all i got to do is pay money
i run an octain booster in the fuel on hot days but the right side back of engine pings badly so im sure its heat soak or bad water flow at back of engine
just wondering if anyone has had these issues before
maybe its abit lean at light throttle
maybe i should try a 72 degree thermostat or maybe even try fitting a better radiator which flows more water
if anyone could suggest anyhting it would be great
thanks
