Title: Oil pressure lost on oil change
Post by: Jan-Erik on 28 January 2011, 09:11:48

Hi.
I can use some help.
A friend was canging oil on my car. After the job there was no oil pressure in the engine. At least not in the headers. they are making a lot of valvenoise. New filter and oil. Is it the oilpump or can it be somthing else? Thevalve next to the filter has been changes with no result. Even tried a second filter.
the car in question are 1996 2.5 V6 CD X25XE

What oil did you use, and how much did you put in?  (where is it on the dipstick now?)

The oil is right on max on the dipstick. The oil is mobile 5w40

No flushing agent and the warning lamp did not go out. I have not messured the pressure since there clairly is none.

It sounds like the oilchange perhaps dislodged some 'gunk' that's now been sucked up and is blocking the oil pickup in the sump, to me..

Probably worth pulling the sump off and checking the pickup - if I recall, on the 2.5s, that's quite easy as you only need to pull the rearmost sump on the engine..

It has been removed and checked. But not by me so it can be worth checking...
Do anyone know if threre is a general problem with theese cars. I am an mechanic and had never had this problem with the omega before. I got the car for nothing bc of this problem.

Was the oil change performed via the sump plug, or the dipstick tube/vacuum extraction?
