Cold this morning!
To bring things up to speed... I replaced the o-rings and saw NO results. The oil pressure will jump from 0 to .5 bar after 8 or 10 seconds then rise like normal to full pressure. That has been the case in the last months.
This morning the temp was hovering around 34 deg and when I started the car (started immediately with NO miss or hiccups) the oil pressure jumped up to .5 bar within 2 seconds of starting and was at full pressure by 3 seconds. Your thoughts. Kevin |

3 Seconds!
I would think full pressure in three seconds would be about as fast as if it were new. Previously, I was wondering if the gage could be sticking for a few seconds. I know on my fuel gage, I have to tap in the face to free the needle. This is common for power plant gages, it is even written into procedures to tap on the face of the gage prior to reading.
Did you get my last email? |

I thought you had died Boob!
Hello Andy,
I got an email from you several weeks ago but not lately. I still have that vacuum line you were needing fro your 300D. How are the wagons doing this morning? Is it cold in Knoxville this morning? Kevin |

Oilslick,
...So....what is the moral of this story? Did you replace the O-rings and start it one time with no results, or did you test this a number of times? If the O-rings were bad and caused the oil to drain out of the filter housing, it would take one start to refill the housing, but after that the problem should go away. It sounds like this is the case, but it is difficult to tell from the thread? If you could clarify, it may help others who read the thread who have the same problem. Thanks.

Oilslick,
Find where the oil pressure gauge line comes out of the engine and install a pressure gauge right at the engine. If the press. still doesn't come up then you know that the problem in NOT in the instrument panel. I got suckered by a faulty pressure sending unit on my 6.3 Diesel and ended up doing a $1,500 overhaul in a classic MAW (might as well) situation. |

Is your oil pan caved in any?
Is the pickup having issues. After you try to gauge right at the engine you might pull the pan and see how things are down there. I just know that you CAN crush a oil pan enough to close the pickup off (that is, if the rubber part fell off the bottom of your pickup that is supposed to allow oil in even when crushed) Hammer+Cement Floor= fixed! Oh and you need a gasket

I'm not sure if this model is susceptible to this problem, but I'd get a new filter and check to make sure it was the right one. Also, replace the o-rings, they are cheap.
The guage on that engine is electric, there is no oil pressure line. I believe the filter is draining back overnight, and the only causes that I know of are wrong filter or bad o-rings. It should stay full so long as the cap is in place, and I'm QUITE certain you would have a serious oil leak if the cap o-ring was bad! Peter
