Dodgy Oil Pressure
Posted: Tue May 24, 2005 9:24 pm
Over the last few weeks, whenever I started my track Sprint from cold, the oil pressure would rise very slowly to around 20-25 psi then after maybe 30 seconds or so it would gradually creep up to it's usual 70 psi. Last weekend I started it up and the oil pressure light wouldn't go out and the gauge reading 0 psi (even with a tickle of the throttle). <!--EZCODE EMOTICON START :eek --><img src=http://www.ezboard.com/intl/aenglish/im ... ns/eek.gif ALT=":eek"><!--EZCODE EMOTICON END--> <br>
<br>
So I drained the oil, binned the filter & removed the oil pump. Re-fitted with a known good pump, new oil & filter, started it up again and still the oil light stayed on, but this time only for a short while, then rising slowly as before. <!--EZCODE EMOTICON START >D --><img src=http://www.ezboard.com/intl/aenglish/im ... s/grin.gif ALT=" >D"><!--EZCODE EMOTICON END--> <br>
<br>
Time to take the sump off, me thinks. So I removed all the sump bolts & dropped the sump. The first thing I noticed was the oil strainer/pick-up pipe had worked itself loose. So instead of drawing oil up through the strainer it was drawing air. <!--EZCODE EMOTICON START :D --><img src=http://www.ezboard.com/intl/aenglish/im ... /happy.gif ALT=":D"><!--EZCODE EMOTICON END--> (sigh of relief).<br>
<br>
Anyway, I took some piccies of one of the mains & one of the big end bearings. There is slight scoring & pitting to them. Do I fit a new set of each whilst I'm there ?<br>

Where's the cheapest place to get them I usually use Rimmers. I need .030 U/S big ends & .020 U/S mains.<br>

Oh! I forgot to say, don't forget to remove the dipstick when dropping the sump off. It makes life a lot easier. <!--EZCODE EMOTICON START :o --><img src=http://www.ezboard.com/intl/aenglish/im ... rassed.gif ALT=":o"><!--EZCODE EMOTICON END--> <br>
