Well I started driving my S4 around today(got a trip permit) And my oil pressure gauge was statrting to go lower (its a mechanical). Well I decided to change the oil (the oil smelled like gas), when I got the oil out it really smelled like gas and was very thin. So I put in some 20w50 and now my oil pressure is about 10psi at idle. Is this probably the damn front cover oring problem? I really don't want it to be since I had to assemble this engine twice and can't deal with removing the engine again.

 

You shouldnt have to remove your engine to fix the o-ring problem. Only the front cover has to come off.

 

Is it fairly easy to take off the oil pan and front cover while the engine is still in the car Jrat?

 

Doh! I forgot about the oil pan.. I cant imagine why it couldnt be done. I must admit, I have only done it with the engine out so I dont have any firsthand experience, but I have heard that people have pulled the front cover, motor installed.

 

How high is the oil pressure supposed to be?

 

j200pruf, ask Aaron Cake about removing the Oil Pan awhile the Engine Is still mounted In the Engine Bay - It's not fun and I cringe at the thought - especially reinstallation.

Our Oil Pressure Regulator Is noted for being less than consistent. Are you taking readings with a stock or aftermarket Guage? KM's on Engine? If you are having problems with the notorious O-Ring at the Front Iron/Cover, expect to see the Stationary Gear Bearings fused to the E-Shaft and Rotor Bearings scored - badly. Atleast that was In my case. [I]Builder[/B] Installed s4 O-Ring on s5 TII setup with Cover Gasket! I digress.

 

I am taking readings with a mechanical oil pressure gauge, once fully warmed idle pressure is 10psi at 4k RPM I am getting 40psi. I have about 40 miles on the motor (I recently rebuilt it).

When I first got the car driving around I was getting great oil pressure, 30-40 psi at idle and 60-80psi at 4k. This was with oil that had quite a bit of gas in it. I noticed that idle pressure was at about 20psi and still getting up to 60 at 4k. I found out that gas fouled oil could be a major issue I decided to change the oil and filter. I put in 20w50 Castrol GTX w/ a puralotor filter. My oil pressure was staying at 20 idle and 60 at 4k. Then my pressure at 3-4k went down to 40 psi, I then noticed idle pressures dropping down to 15-10.

I am pretty sure that the oring is bad seeing as I used a Atkins rebuild kit (mostly mazda parts) with the mazda front cover and oring. I should have dealt with that earlier, but I thought I would be ok, big ******* mistake that I am paying for now. I am really getting sick and tired of this ****, especcially since I spent 20 bucks for a 21 day temp tag. Now the car isn't driveable and I only can buy one more 21 day temporary tag.
Sry but I had to rant a little bit.

 

Oops, substitute Oil Pressure Regulator with stock Oil Pressure Guage, my bad.

Even with a new one I found It not holding up. Perhaps It was the (old) wiring to It...I have an aftermarket one thats assuming the duty now.

 

So is most of everyone aggreed that I have the damn oring problem. I think that I will get another gauge just to check.
I just called someone and they said it was going to cost about $300 to fix.
