Oil pressure questions...

**The_Wretched** · 12-27-2008, 08:29 AM

My coolant level drooped and I refilled. But now my oil is goi g up and down. It dropped below 40 a few times. What could be the prob? I thought normal pressure was 50-55. Now I'm getting worried. It went as high as 70 ish. This was during normal driving.

My coolant level resulted in high temperature. But that is now fixed.

try changing the oil sending unit

No such thing as normal Pressure. Mine usually runs around 30-40 at idle,All depends on wear, the oil pump, the viscosity of the oil etc. Mine gets as low as 20 on the hottest day. Nothing to worry about. If your paranoid get a new sender and drop in a ls6 ported pump that has been shimmed. As long as its above 30 at cold idle I wouldnt worry about it honestly.

Pop off the intake and it should be easily reachable.

10 psi per 1k rpm.

Really easy install. Its right behind the intake on the drivers side.

But no need to pull the intake -nothing is wrong. Change the oil if it is ready or u wanna feel like you're doing something.

Agreed. Oil pressure sending uning unit is fine. Replace that when you break it replacing your intake.

Change your oil I slung a belt one time ran hot and my oil pressure was all over the place untill I changed my oil.

you musta had a bunch of sludge in there that will casuse sudden twitches in the guage, changing oil may help quite a bit. What weight of oil are you using?

mine usually never drops below 40 but on a cold start it will be up there round 75 at idle... never had a problem with not enough pressure...

I didnt have the car very long before it happened. The guy i bought the car from said it was mobil 1 5w30 so I didn't change it as soon as I got it but all I know is I have run that oil in other cars for as many as 6000 miles and nerver had any come out as thin and shitty looking as this stuff was.
