But when warm oil pressure is 28psi when driving its around 60psi but cold start its below 10 and oil light flashes. Please help Quote Link to post Share on other sites
AdamB Posted February 25, 2013 Share Posted February 25, 2013 What oil filter did you use? On cold start the pressure should be pretty high, around 5 bar since the oil is still thick it creates a greater pressure. Quote Link to post Share on other sites
Chrishoughton1989 Posted February 25, 2013 Author Share Posted February 25, 2013 Was a Mann oil filter. No my pressure is deff low when cold. Quote Link to post Share on other sites
MARC MOSS Posted February 25, 2013 Share Posted February 25, 2013 My pressure was at 55-60 psi when cold lowering to 15-20 when hot on tick over, something's not right Quote Link to post Share on other sites
Chrishoughton1989 Posted February 25, 2013 Author Share Posted February 25, 2013 Is it possible the wires wrong way? Would that do that Quote Link to post Share on other sites
turbo Grant Posted February 25, 2013 Share Posted February 25, 2013 Only one wire to the oil pressure switch. That shouldn't be wrong. Could be the strainer in the sump blocked a bit. The oil change could have dislodged some shit Quote Link to post Share on other sites
Chrishoughton1989 Posted February 25, 2013 Author Share Posted February 25, 2013 I have a after market oil pressure gauge on sandwich plate for oil filter with two wires. Quote Link to post Share on other sites
turbo Grant Posted February 25, 2013 Share Posted February 25, 2013 Your on about the oil light on the dash flickering? The 2 wire pressure sensor will have an earth and a signal wire Quote Link to post Share on other sites
Chrishoughton1989 Posted February 25, 2013 Author Share Posted February 25, 2013 I have the dash light flickering from cold and a aftermarket oil psi guage. This starts at 10 psi from cold. Low oil pressure when cold but fine when warm. Quote Link to post Share on other sites
Chrishoughton1989 Posted March 4, 2013 Author Share Posted March 4, 2013 At last. Was the o ring on pick up pipe. Quote Link to post Share on other sites
turbo Grant Posted March 4, 2013 Share Posted March 4, 2013 Glad you found out the problem. Had to be some thing on the pick up side of things Quote Link to post Share on other sites
