hi all 1st time for everthing so i hope some one can help with a little question i recently tested a rx7 when it is on tick over the oil pressure was fine but when we road tested the gauge dropped off to just above 0 psi but came back when the throttle was blipped i was told this was normal and a common fault with the gauge the oil pressure came back on idle is this true !!
thanks
The oil pressure senders are known to go faulty over time which will make the guage act funny
thks kash
could you tell me can it be concerted to a pipe fed oil gauge
If it helps, mine does the same - jumps up to correct value (between 4-8kg/cm2) on start-up then drops to zero as the oil warms up. As soon as I go on boost though the oil starts getting pumped through the engine and turbos and all is well again!!
I wouldn;t worry about it too much!! You should be checking the oil level every week anyway!! :p
thanks trotter that exaclty what it does
as Kash said it will be the sensor not the gauge. A lot of us put aftermarket gauges in to a oil sandwich plate so you get a true reading of pressure
