That's because it/s a different dash! mine's a /95. I think that you think I'm maybe a UK idiot or something. My whole thrust on this is that yes, I've noticed the light coming on for a few months. First off I checked and replaced both PRESSURE senders, against my gut instinct as oil lights are not normally wrong, it's usually down to deteriorating engine condition in my view. Anyway, having done that and changed the oil for Mobil-1 (as usual every 7500 miles). the symptoms eased. HOWEVER, as I've said a few times, I'm just looking to get the cooler to control the oil temp at a few degrees lower than 100. I totally get that the temps at present are within normal ranges, but can you not get that the gradual build-up of these symptoms is maybe an indication of bearing wear, and that by reducing the oil temp a few degrees would extend engine life considerably?

The next step before pulling the motor to me are:- 1) maybe change the oil cooling from a water/oil heat exchanger to air/oil H/E; 2, fit a proper analogue gauge, as the one in the dash is only calibrated at 0 and 550 kPa, with quarters and half way point. 550 kPa is 79pisg. Maybe other way around on the order! By the way, at highway revs (1500-2000rpm) oil pressure is showing 1/4 full scale, or around 20psig.

 

Your correct, your '95 does not have a digital oil pressure gauge.
Now you can see the importance of always listing the year of the car when asking questions.
The C4 ran from 1984 through 1996, and there were lots of changes during that time.

Also, your '95 does not have any type of factory oil cooler.
The water/oil heat exchanger your referring too was on the earlier models.
You could install an aftermarket oil cooler of your choice though.

 

[QUOTE=Tom400CFI;1587772720]Well, I'd say your opinion is wrong. Highway trips in NO WAY, "flog the life out of it" That just ain't true, regardless of your "opinion". Car can go right past 300k doing highway trips. As for scaring people; you've gone and scared yourself right out of driving it, and now you're posting misinformation about how highway driving is detrimental, which just ain't true, man.

People tell me riding my motorcycles is dangerous but I don't listen to them... As for scaring people and posting misinformation "man"... you'd have to be pretty weak sort of person to be "scared" out of driving your car as much as you want if that's what you want to do. I thought Yanks were like Aussies... I think I have just changed my opinion on that also and I will say goodbye to this forum.

 

No! Absolutely not. Lowering your oil temperature "a few degrees" is in NO WAY, fixing the problem, or is it going to "extend the engine life considerably". No way. The ROOT PROBLEM here, and what you should have posted in the first place is that you have low oil pressure and what can you do about it. Year would have helped a lot, too, as RollaMo-LT4 stated.



Finally, some useful data! That is barely adequate. Spec is 10 PSI/1000 RPM, so your indicated 20 PSI @ 1900-2000 RPM is "good enough". However, no healthy SBC actually runs at 10 PSI/1000 RPM so that value would indicate to ME, bearing wear, (odd given your mileage and maintenance intervals), oil pump issue, or gauge issue.

Again, I'd put a mechanical gauge on it FIRST. You have to know what is going on in there. Have to.

Second, if the pressure was low, you could try a higher weight oil, since your right on the cusp of acceptable.

Last you could drop your pan and replace the crank and rod bearing shells in the car, which THAT would "extend engine life considerably".



^This.



Hey...I'm just pointing two things;
1. You have gone and scared yourself, out of driving your own car as much as you want, so...
2. People come on here, not knowing, in search of good info. They read your post, and think that driving the 'Vette on road trips will hurt it and that is wrong. It's misinformation!

Get butt hurt and leave if you want....OR hear what I'm saying and learn something.
