higher oil pressure?

[TSITurbo95]

Ok so i was driving home from work yesterday and noticed mu oil pressure gauge was reading in the 100's around 80mph. Somethibwas wrong so i slowed down but was still hover han normal. Checked oil when i got one and it was fine. This morning when i started my car i let her warm up some and it was still higher than normal, not near 100 bit sill high. Now driving to work its around 65-75mph usually around 50ish psi. Whats going on?

Edit* at idle its between 25-35psi.

My oil pressure about more than doubled itself. What's wrong?

bad rings/ blown piston possibly.. could be something else

 

[TSITurbo95]

Possible bad sender? Stock oil pressure gauge is at the first bar only.

Check the connection, for one, where it clips onto the sensor. That thing is notorious for sliding off, getting covered in crud, and just plain not reading correctly.

As for the AM Gauge... you said it was running funny? Please explain?

 

[TSITurbo95]

The car runs fine, just my after market oil pressure gauge is reading high. It has never been that high so it vait my attention. Ill check the connections when i get home. But thecar runs fine, oil dipstick doesn't pop out no oil in my oil catch can and oil level is fine too.

 

[Chazz1978]

Yeah. This has happend to me. The clip for the sending unit gets a bad contact. Since you have an aftermarket. Im not sure how you have it set up. But its a bad contact or unit.

 

[TSITurbo95]

Both of the units going bad at the same time? Highly unlikely.

It is possible that the oil relief valve could have gotten stuck closed, not relieving the high oil pressure.

 

[TSITurbo95]

Possibly how do i check? Im going to chang my oil and see what happens

You have to take the oil filter housing off...

 

[boostforfun]

I has the same problem.. mind ended,up being a bad ring. Do a compression test or leakdown to find out for sure.

 

[TSITurbo95]

Ok so ill try a compression test soon and hangs my oil a well to see if it solves anything. Any other suggestions on my issue?

 

[knochgoon24]

I've had 2 things cause similar symptoms.

-Bad connection on the sender.
-Oil needed changed.

Reading too high on TWO gauges means the oil pressure IS too high. The oil pressure relief is what I'd be looking at. Oil loses thickness with time, and will show lower pressure with time. Compression has nothing to do with oil pressure. It is the same kind of absent-mindedness that says throttle position affects oil pressure. It is ONLY RPM, and viscosity (temperature applies) dependent. You don't need to take the filter housing off to check if the relief is moving freely. There is a large bolt on the bottom of the housing, probably near an inch in size. Take that off and the relief valve is in there.

 

[TSITurbo95]

Ok so while chaning my oil take that bolt off and check in there. What exactly am i looking for? What do i need to do once i take that bolt off?

 

[ramsack]

There will be a spring in there, and a gasket/crush washer for the bolt. The relief valve may or may not fall out my itself. Just poke something not metal up there to try to get it out. It should even spin about inside of there easy with very little force. If it doesn't move then it is seized by most likely a solid piece of something. That would then be the time to take the filter housing off and find out what's going on.

 

[TSITurbo95]

What will it hurt to drive it with high oil pressure?

 

[ramsack]

Depending on how high it is. Not very good to go over 80, but it doesn't really hurt anything mechanically, just blows out seals. To me it's a sign that it's not gooe because it changed all of a sudden.

 

[TSITurbo95]

Gotcha. Im gonna try the above then check back in. Lastly should i continue using 10w30 full synthetic for my oil? I use it all year round

 

[ramsack]

10w30 is what is recommended, and 5w30 is recommended for very cold climates, like Siberia.

So wait, are both senders bad?

My stock gauge has never worked, so I don't know if that's normal.

Don't think so. What are the odds of both my senders both aftermarket and stock go bad at the same exact time and both read high op? Not very likely

Ok so I came across some issues so did not get to change my oil, but that is first on my list tomorrow. From my external wastegate open dump was too short and burnt the coating off my alternator wire, so I had to do a repair job, and extended the dump tube and put some header wrap around it. Also I cleaned the connections but still no go. But any other suggestions on the oil problem?

 

[TSITurbo95]

Ok, changed oil, old oil and filter look normal. Still have higher than normal oil pressure.

Well, at least you're not a Dick or anything. I just figured that a pressurized crankcase, while maymight simulate high oil pressure by increasing all pressure in the crankcase. But your right, I'm just absent minded...

 

[TSITurbo95]

Changed PVC valve, and still nothing. Going to try the relief valve shortly.
