Hi there. I've got a 2005 hawkeye sti on 30,000 with a full aps 3" decat exhaust. Asp induction. Fuel pump remap and it's running bout 350 bhp 350 torque. It's normally used 5 out of 7 days but today was the first time I've used it to day in about 5 days. And when I started it the oil pressure light on the dash went off on start up as normal but the pressure on the defi took longer than normal to build up. I only noticed as the defi warning came on. But once built up was fine. Could it be a sticky gauge or sender. Or could oil pump be on its way out. Or is it normal if the car not been used and its getting colder. As I said the oil light on the dash went off as normal


Thanks a lot.
James

 

Did the pressure fluctuate once it was running? Could be evidence of a cracked oil pick up pipe.

 

What sort of fluctuation is considered normal?

My Defi fluctuates by about 0.2-0.4 bar.

It wasn't fluctuating before I replaced the T-loom adaptor with a Y-connector in order to have both the OE low pressure sender and Defi connected.

 

Maybe extra cold weather?.

 

No. Once started went to 6 bar and went down as warmed up as normal to bout two bar

 

And how can I Cheak if oil pick up cracked and how easy to replace

 

Its a sump off job to remove the oil pickup pipe to see if its fractured.

Ok thanks everyone

 

Sounds fine, pick up pipe issue is rare. Cold weather will have an effect.

 

To b honest it's only started doin this since its been colder. And the oil light on the dash is goin off as normal
