Motorraum: Oil pressure

[Beumers]

Hi all.
The oil light on my dash stays on for more than a few seconds.
Reading the oil problems specific for this engine I have these questions.
When I turn of the car how long does it take the oil housing with the oil filter to drain empty caused by faulty oilvalves.
I asume when the oilvalves are oké the oil will not run out in time.

Regards Henk Beumers.

No need to reply in English.

Hallo Holger.
When I click the link, I get the page with Salzpuckel's discription about the revision of the B30 (Ventilen im Ölfiltergäuse vom B30). What is the B30? Is it the M30B30?
There's a link on the end of that page where the valves look very different.
It seems there are more types of housings with different valve types. Is that correct. How can I tell what kind of valves I have.

Henk.

I have a DIY instruction on my website for the M30 engine, go to fixes>>oil system, it is with pictures

Hallo Henk,

nach dem Baujahr deines 735i kannst du nur das auf der Seite von Salzpuckel haben. Den R6 Motor gibt es in zwei Formen M30B30 und M30B35,
der eine hat 3,0 Liter =B30 und der 3,5 Liter =B35.
Beide haben das alte Ölfiltergehäuse. Erst ab Baujahr 1992 sollte es das neuere sein. Ich glaube aber, das es ab da keinen B35 mehr gab und nur noch der M30B30 gebaut wurde.

Schreib einfach Salzpuckel an, der kann dir so einen Reperatursatz anbieten.
Oder du holst dir ein neues Ölgehäuse, macht so um die 170€

Die Öl Kontrol Lampe sollte normal schon beim Starten ausgehen so 1-2 Sec.
länger nicht. Sind es so um die 4-5 Sec. ist es das leer gelaufene Ölgehäuse.

Grüße Holger

Thanks for the reply Erich and Holger.
I checked all your articles about this car times ago when I started to service this car myself so I knew where to look but there is no harm in reminding me.
It's that just now I stumbled across this page with totaly different valves so I was a bit confused.
This morning I opened the oil housing and it was completely emty as expected. The valve on the left is demaged ( overpressure valve I think )
The other one is oké. The valve itself and some parts were still in the oil housing. I took them out so they can't demage anything. ( can they get into the engine? )
I'm a bit short in time at the moment so I'll try and find a used one.
I can fix mine than later and replace it. If it can't be helped I'll buy a new one.
If somebody has a used one lying around I would like to buy it.
Is there a flow pattern available how the oil is transported through the engine?
I'll keep you posted.
Thanks for now. Henk.

Hi.
I can get a housing with good working valves from a 1992 730. My housing has connections for the oilcooler. On the 1992 housing I can't see if there is a connection for an oilcooler. There is no reason why I could run my car without the oilcooler for a while is there?
Henk.
