Hi Again sorry for the delay, here is the update, first off I saw that where they had done the pressure test it must of been leaking as the sump was covered in oil that led to the sensor, also the connector to the sensor does not clip on, clip is knackered so it is free to drift? Anyway I've cleaned it all out & a long story short I put it all back together & oil flushed it twice. Now I have included a pic of my tester & would like you all to tell me if the readings are good as I don't trust myself lol, I have marked it with two red lines the lower line is idol the top one 4000 rpm, the tester needle was rock solid no shaking, & I waited for the rad fan to come on before I took the any readings. Now if you look at the pic I thought those readings were good? but please let me have your input before I charge off down the motorway. The oil pickup was partly blocked & the oil pan had some gritty crap in it bit I have seen worse, the first flush came out very black the second flush still dark but noticeable cleaner ..... What do you think ????
