Oil PSI question

Put a temp mechanical gauge on it and try again.

 

A long time ago I made one with a very long hose and just routed it inside the car and taped it somewhere convienent. At that point you are going to have to duplicate the circumstances that cause the trouble.

The other choice is to just put a new sender in it and give it a try.

 

At the temps you quoted I would be hoping it was cheap oil breaking down but even that does not explain all the symptoms. The motors are really good, especially the bottom ends. It is a very high probability that it is a gauge problem.

 

Hey Brian are you kidding me?! taking on another oil presure issue. You planned this right? Wasn't there some sort of balloon or oil pumps with no oil in them or.... what the hell did "doubtful that I have any brains" say about that oil presure thing again? Is that you in the avatar? LMAO. Regards, Vern

 

I know, just call me stupid. I have burns from the stove on both hands, seems once is just not enough.

The above link is not for a Ferrari, just a starting point for your hypothetical oil pressure question.

Have you looked to see if you have any oil in your coolant or coolant in your oil?

 

In my 550 I have had the pressure gauge, showing both increased pressure and no pressure in similar circumstances. After four new senders over a period of less than 12 months, I have had my car converted to a mechanical gauge.

 

Nice idea. Any details available about that conversion? That would be a nice gauge to have.

 

It was very straightforward, same as done with Porsche race cars. (apparently they use the same bodgy sensor) I don't have all of the details here on the fittings required, but can post them in a couple of days.

 

Are you implying he has a blown headgasket?

 

It comes from laying on top of the motor.

 

LOL!

No, mate! Just wondering if he'd had a look-see (just in case). It was a hypothetical question, after all.

 

Thanks, Stephen. The mechanical gauge would seem to solve quite a few bad readings from the electric units.

 

Ok,cool Just trying to keep you on the straight and narrow

 

ditto on my GT4, it took me an hour and $150 to convert to mechanical after I got all the gear together

 

FYI, Aussie ADR rules (and general common sense) dictate that no engine fluids (or vacuum/boost lines) should enter the cockpit.

If you're approaching a corner at the end of a straight, or just going for a long fast drive somewhere, and the oil line decides to spray hot oil in your face/crutch, you'll understand more!!

This is why mechanical pressure and temperature gauges were phased out long ago.

They should only be used for diagnostic purposes.

 

I recently had a question on the accuracy of a stock sender/gauge. In order to check the system, I put together a test jig. By welding a nut (the size to fit the sender) to an air fitting, I was able to verify the reading of the dash gauge compared to an accurate air regulated supply. I found the stock gauge read low acros the board, but not in a linear, or predictable way. That is, it didn't read low by a predictable percentage. The final outcome was to keep the set up as is, rather than chase the problem by throwing new parts at it.

Been there done that Well kinda I have a Autometer oil pressure
gauge and chrome pod mounted on top of windscreen wiper grill,outside the car in front of the windscreen. One day,the pressure line split and sprayed the entire drivers side of the windscreen full of engine oil. Lucky i was not in the main part of town and was able to slow the car down safely and avoided causing an accident. I still have the gauge on the car,but now its an electric one

 

tell me that's not the 348 you're talking about..

pleeeeease!

 

Did you have the matching oversized tacho and shift light?

 

Nah nah,f*ck that! My old Ford Fairlane
