ok heres the deal, my oil pressure guage isnt working. (im hoping its the oil pressure guage). My pressure guage reads zero or below while im cruising(like its not even getting power) and every once in a while it will come up to a somewhat normal level. Then sharpley drop off again...
Has anyone else had this problem and if so what was the culpret. I have driven it aobut 75miles since this started, and nothing unusual with the way my engine runs.
I have an auto-x this sat and sun and would like to get the problem fixed before then.
Thanks for any help!!

 

Sounds like the guage to me.... sending unit possibly.... Use the hayne's manual to check it... I'm pretty sure it's checked by resistance...

SO do you think I will still be able to auto-x this weekend?? or should I not risk it. ITs the last meet for the season :-( and dont want to miss it.

 

check for leaks and check the oil. if all looks good go run it.

Yea, nothing new or out of the ordinary just kinnda worried me when im driving down the freeway and glance at my guages and reads zero pressure... but guess ill just live with it for now...
Thanks guys!!.

if anyone else has any different advice would love to hear it.

 

Run the event!

If your oil pressure truly is zero, you'd know by now. Our gauges are not known for being reliable (or accurate for that matter) so I wouldn't worry about it. Besides, if the oil pressure was gone, the gauge should still go up a little when the car is revved, unless there's a hole the size of a quarter in the oilpan.

 

Whoo Hoo Will try to get some pics from this weekend!!
Thanks guys!

 

You just described mine old one in my 85 to the tee... I bought a new sender from the dealer and all is fine now... Make sure the wiring connection on the old one is clean, and if you have to buy a new one, be sure to take vaseline with you to the dealer, its 57 bucks

 

ok someone needs my oil pressure sender. i got what i think it is off of a parts car of mine. is it the sensor lookin thing right under the water oil cooler that needs a 14mm wrench to get off and has the weird slide on connector?

 

yeah ... that sounds like it.

also keep in mind that the sender "might" be just fine, and the wire that attaches to the sensor may be loose or crammed with oily crap. just something to consider ... try taking it off, cleaning it, and seeing if it fits any more snug. if that doesn't work, then condemn the sender unit.

about the autocross, i agree with everyone else. if you really had no oil pressure and drove 75 miles, then the title of this thread would have probably started with "F@#K! my motor just ..."

 

All right, today I changed my oil and filter, and all of a sudden it works..... my oil was petty clean, so I dunno. still running great.
thanks for the help. will try to post some pics.
My first auto-x since I got the Kosies and BFGoodrich G-force Kd's. so pretty excited.

 

yeah, i had the same problem, i wasnt smart enough to get out and call AAA, now it sits in my driveway waiting for a rebuild....back to my search for a cheap kit

Same thing happened to my FC right when I bought it... the guage was really sparatic is working, sometimes 0, sometimes shooting up to 60, floating back to 25, then dropping back to 0. I got worried, dumped some 2stroke oil in it, and no sooner then I spent the $ on the oil the pressure read normal again... I went home, changed the oil and filter and haven't had a problem since.
