Guest Danny. Posted July 18, 2006 Share Posted July 18, 2006 Hello Supra people. My car had a water leak from one of the rubber heater hoses at the back of the engine bay today. It didn't lose all the water and the temp gauge didn't show above normal (halfway). However since the hose problem the Low Oil Pressure light (the red one) is coming on at low revs and the engine is rattling quite badly from the bottom end, also only at low revs. Compression test is OK. I presume the engine will have to come out and have everything checked over and at the very least the conrod bearings and main bearings replaced. But what could be causing the low oil pressure? Should I change the oil pump while the engine is out? What else could cause low oil pressure? Thank you -- Daniel 1997 VVTi TT Auto Quote Link to comment Share on other sites More sharing options...
DannoSupra Posted July 18, 2006 Share Posted July 18, 2006 Stupid question, but have you checked your oil level? Quote Link to comment Share on other sites More sharing options...
Guest Danny. Posted July 18, 2006 Share Posted July 18, 2006 ah yes, I should have mentioned that. The oil level is fine. Quote Link to comment Share on other sites More sharing options...
wkdtime Posted July 18, 2006 Share Posted July 18, 2006 At what revs do you get the rattle and Low oil pressure light flicker on? Quote Link to comment Share on other sites More sharing options...
Guest Danny. Posted July 18, 2006 Share Posted July 18, 2006 Only at tickover when the car is stationary or below about 2000rpm while driving. Quote Link to comment Share on other sites More sharing options...
wkdtime Posted July 18, 2006 Share Posted July 18, 2006 I wouldnt Drive it anymore mate until you get to the bottom of the problem, May be a worn oil pump or if your lucky the oil pressure switch...? Quote Link to comment Share on other sites More sharing options...
bondango Posted July 18, 2006 Share Posted July 18, 2006 If any of the ends have been going over time, you will get a build up of swarf on the oil pump filter gause, this gradually builds up until the pump cant do its job 100% and the end usually goes at this stage. If the noise rises inline with revs and is very noticable at around 3000rpms then yup i would say defo an end bearing. I Think the hose episode just happened at the same time but is totally unrelated. Quote Link to comment Share on other sites More sharing options...
bondango Posted July 18, 2006 Share Posted July 18, 2006 Danny theres one other thing it could be, watch this video..(7mgte but 2J's give a similar sound) http://video.google.co.uk/videoplay?docid=166330623163766700&q=engine+knocking Have a listen to that knocking, its not as constant as an end bearing would sound, and usually indicates the oil pump drive is fooked Quote Link to comment Share on other sites More sharing options...
