Terry Whatley Posted June 29, 2004 Report Share Posted June 29, 2004 I just noticed oil present IN the Gauge - not a lot! Is this very serious - will it burst and spray oil behind the dash - can I repair or is a replacement jobby? The readings are OK. I endorse views of others on the Forum - this alone is almost worth the subs. Quote Link to post Share on other sites
john.r.davies Posted June 29, 2004 Report Share Posted June 29, 2004 Terry, This style of gauge is a "Bourdon" gauge - there is a coil of slightly flattened tube inside, one end fixed, the other linked by a gear train to the needle. As the pressure rises the coil, er, uncoils, and moves the needle accordingly. If you have oil in the gauge, then it is leaking from the Bourdon coil, or else at the connection at the back and into the body of the gauge. The first is terminal, I suppose, the second might be fixable by gentle tightening. I don't think oil will "spray" oil into your car - the connecting tube is very fine, so resistance is high and flow will be low, but it will certainly drip, drip and make a mess.
