Oil Temp, Oil Press, Water temp readings.

Finally got all my gauges install, i know these are cheaper Taiwanese gauges (can not even compare to DEFI, Apexi or HKS). I do know know how accurate the reading is but you can see that the oil temp tint is not even and is much darker one side so you get what you pay for. :) Below is some rough guide and readings i got from the gauge.

Oil Pressure (>2 kg/mm2): Idle (2~3), Cruising (3~5), VTEC (6~6.5)
High oil pressure : ( suddenly increases) Pressure relief valve could be not working.
Low oil pressure: Insufficient oil in engine, leakage, damaged oil pump, and worn out oil.

Oil Temp (<130 degC): Idle (85~90), Cruising (80~90), VTEC (slightly above 100)
High oil Temp: Insufficient oil level, insufficient cooling (if modded), blocked passage, damaged oil pump, bad bearing and worn out oil.
Low oil Temp: Over cooled engine, normally due to oversize oil cooler used.

Water Temp (<110 degC): Idle (85~90), Cruising (80~90), VTEC (slightly below 100)
High water Temp: Thermostat jam, insufficient water, insufficient cooling (if modded), blocked passage, damaged water pump, and worn out coolant (normally water is ok unless heavy mod engine).
Low water Temp: Wrong radiator size causing overcooling or slow heating up.

I hope the readers don mind that these are cheap gauges. DEFI, APEXI, HKS or GREDDY are way out of my budget. Those 1 unit of Japanese Gauges can buy the whole set (3 units) of Taiwanese Gauge with loose change too. Damn. But I do not know the reliability of these none Japan gauges so let see how long it can last.
