So I was pulling into the underground garage at my apartment and my Defi Oil pressure gauge starts beeping at the pre-determined warning of 0.6 bar. Thinking i just brought the rpms down to low since it normally happens but pressure goes back up after I blip the throttle, it didn't this time. While I was cruising down the garage ramp I noticed the gauge slowly going down from 0.6 bar till it was at 0 bar. Luckily I had just made it to my parking spot and I was able to shut the engine off. I check the oil and the level is normal. So one of two things possibly happened.

1. the oil pick up tube cracked/broke off

2. the oil pressure sending unit crapped out on me on my Defi gauge

what confuses me is why didn't the Subaru dummy oil pressure light come on in the dash? This fact kinda supports why the oil pressure sending unit possibly crapped out instead of the oil pick tube breaking off.

but then again if the oil pick up tube broke off it would explain why I went from 0.6 bar to 0 bar in a matter of 10 seconds.

either way I will tow the car to the Hobby shop this weekend and install the Killer B oil pickup tube whether it is broke off or not. Thank goodness I have an oil pressure gauge so I was able to see the problem quickly and react to it buy shutting off the motor.

 

Interested to see if the pickup tube cracked or not. Subscribed.

edit: Good job on catching it before it was catastrophic.

 

hmmm I hope everything is good man!

 

If it isn't I will just turn another bad situation to a good one by picking me up a built motor. kinda like the time when my 05 got t-boned and all it was, was a blessing in disguise.

 

fixed it for you! you and your "accident"

 

hey it was an accident. so stay on topic Shaggy

 

good to hear you caught it too.
i ordered the killer b too anad plan to install on the next few oil changes...

 

I want to do a safe test to see if oil is getting pumped/circulated in the motor. The only thing I can think of doing is disconnecting the coils and removing the stock pressure sensor and then have someone crank it a few times to see if oil spurts out. The first question I have is will this be safe to do with all the oil currently at the bottom of the pan? I figure it would since most motors that have been sitting for a few hours to days only barley have a light coat of oil on the moving parts prior to start up.

So granted oil starts to spurt out while we are cranking the motor I would imagine it is safe to assume the oil pick up tube is intact and the oil pump is good? So that would obviously point to my Defi oil sender being bad. Either way I will be replacing the oil pick up tube with the Killer B one this saturday.
