CarlW Posted November 28, 2016 Share Posted November 28, 2016 Hi I seem to be having an issue with my oil pressure gauge. When I turn the car on, engine not started, the gauge shoots up to three quarter. When I then start the car it treats that level as the base and essentially reads off the scale. Has anybody seen this before and do you reckon the fault is with the gauge or the sender? I'm thinking about changing the gauges to check as they're on eBay for £20. I called my local stealer about the sender and they are quoting £120! Thanks Carl Quote Link to comment Share on other sites More sharing options...
Aashenfox Posted November 28, 2016 Share Posted November 28, 2016 (edited) Problems with this gauge are extremely common it seems to be a weak point. 90% of the time the sender is at fault, though I haven't actually seen the exact symptoms you describe in order to be sure, I've just read a lot about this because I bought my car with a bad gauge/sender. You already noted you can get the gauges themselves for next to nothing, I just wanted to point out something about changing the sender. Basically, don't do it. At the factory, the sender is torqued to the hand strength of a 10 year old (11lb-ft) and RTV is used, apparently it is very common to split the oil pan (the metal shears around the thread) when tightening the new one with only hand strength (some have even done it while REMOVING the old one!). What I've seen recommended (and what I'm going to do, as my sender doesn't work at all), is put an oil filter sandwich adapter and connect the new oil pressure sender to that (it's a 1/8 BSP the sender, so you may need a 1/8 NPT adapter). Then simply leave the old one in place forever. In our cars, we are lucky, oil filter is right next to sender. Get a second hand sender from one of the vendors here for about 15 quid and a sandwich adapter from anywhere for another 30 quid and DIY next oil change. This is a really easy DIY. EDIT: Source in case anyone is wondering... http://my350z.com/fo...ml#post10111517 Decided to finish up my own research, so here are the parts I'll be buying, if it helps... (I already asked for a sender from a vendor) Sandwich adapter: http://www.ebay.co.uk/itm/231714278165 and here's the thread adapter too... http://www.ebay.co.uk/itm/111430856008 Edited November 28, 2016 by Aashenfox Quote Link to comment Share on other sites More sharing options...
