john c Posted October 7, 2016 Report Share Posted October 7, 2016 Oil pressure upon starting from cold with choke is 70+ on gauge, a stable tickover when warmed up, reads 40, if no traffic stops no problem. However, after an hour of use with regular traffic stops, the temp tends to rise, though the fan cutting in restores temp to just above normal, the oil pressure reads 65+ @2000, but if traffic persists, tickover oil pressure can fall to Minus 5. blipping of the throttle will restore to 30. Getting back on the move will keep it above 50. Starting up a couple of hours later, pressure is 30-40 at tickover and 70plus at 2000 revs. I would appreciate your views on what may be need sorting?, thanks and regards, john Quote Link to post Share on other sites
TR5tar Posted October 7, 2016 Report Share Posted October 7, 2016 Hi John,I don't think it's unusual for the tick over oil pressure to drop when the car is fully warmed up, I know mine does that. I'm sure that others who are more knowledgeable will be along shortly to advise. However, so that your post is easily found by those that can offer you more help, it might be better for you to re-post it under our Technical Forum, either under Technical Chat - http://www.tr-register.co.uk/forums/index.php?/forum/22-tr-technical-chat/ - or one of the sections devoted to specific models. Hope that helps. Darren Quote Link to post Share on other sites
boxofbits Posted October 7, 2016 Report Share Posted October 7, 2016 Hi John +1 on Darren's comment but the only thing you could check is the oil pressure release valve which might not be seating correctly maybe. I take it your filter and oil are good. I've never seen a gauge which will register a minus figure, and can't think what use that would be. You've either got some pressure or you haven't .
