just need reasurrance really, normally my oil pressure is really good, on cold start its 5bar and takes a good 10-15 mins before it drops 3 bar at idle, then shoots straight back to 5 when any throttle applied, all perfectly normal.
but yesterday idle pressure fluctuated between 2-3bar eventually dropping to 2bar, and taking a little bit longer to rise when revved, now im pretty much assuming its down to lots of traffic and warmish weather, thing is ive been stuck in traffice in warmer weather and not had this, and oil is changed regular.
which got me thinking about the oil cooler, if the thermostatic valve was faulty the oil wouldent be cooling as much (obviously) i suppose the only way to monitor is by adding a oil temp guage, then again if it is working the pressure could drop due to the extra travel through the cooler.
i know 2bar at idle is not a problem and as long as it doesent drop at high revs it ok , just wondered if any one else was noticing changes??
