radness 0 Posted June 28, 2008 Hi guys, A good friend of mine fitted the KR cam to my 9a'er. First and only mod i've done so far. I took it out for a drive for 20 minutes , wasn't horsing it but i noticed it did pull a bit better from 3000 rpm, and felt a bit more lively, however i used the MFA to check the oil temp and it's stuck at 160c, the coiolant is showing around 80c. Before this cam went in the engine only ever showed a max of 115c (due to my radiator switch etc..) I would assume that 160c is the max value that the temp sensor can report and so it's a fault with it, as surely oil tempature of 160c would cause my coolant temp to go skywards? I went inside and left the engine off for 20 minutes and after i turned it back on it was still at 160c, i assume something this hot would cool down quick (atlteast by 5-20c in the space of 20 minutes) Would something be disconnected? The guy that did the cam for me is a good guy and knows his onions and i dont want to go accusing him of anything as im sure he hasn't done anything wrong.but maybe i need the check a wire or something?

Dec 1 Posted June 28, 2008 The sender for the oil temp is a single pin sender at the back of the head on the passenger side. It's right at the top, near the rocker cover. so could well have been left unplugged when you had the cams changed! :wink: Quote Share this post Link to post Share on other sites

flusted 0 Posted June 29, 2008 the wire is green with black tracer, it must be earthing somewhere to make the gauge do that Quote Share this post Link to post Share on other sites
radness 0 Posted June 29, 2008 the wire is green with black tracer, it must be earthing somewhere to make the gauge do that I haven't had a look yet, but i was thinking about it lastnight while i was trying to get asleep...does anyone else do this? Anyway, a good bit of oil was spilt on that side of the engine (passenger side) , does oil act as a conductor? Quote Share this post Link to post Share on other sites
Dec 1 Posted June 29, 2008 Nope, oil wont conduct; especially for a low amp 12v source like that sender. Chances are that the wire is hanging down somewhere and is in contact with the block etc. Just take a look back there, will most prob take 30 secs to fix! :wink: Quote Share this post Link to post Share on other sites

boost monkey 0 Posted June 29, 2008 Good news! If you see your oil temp hit 160 there are some serious issues though! :shock: Quote Share this post Link to post Share on other sites
