E90 engine oil leak experience

Re: E90 engine oil leak experience

Hi All,

I've come over from Japanese car ownership and I was wondering if there are lower temperature thermostats available for BMW cars to allow them to run at lower temperatures? Many Japanese after market brands offer such lower temperature thermostats for Japanese cars. I figure that these failing gaskets could be due to high running temperatures of the continental engines in our hot climate and urban driving conditions.

Just my thoughts. Cheers.

Re: E90 engine oil leak experience

I had a similar problem on my 2006 e90 - oil leak in engine bay. Mileage approx 100k. Sent to PML, and they quoted about $2k. Got a quote from one of the sponsor workshop here and was quoted $1k+ to replace "all related seals" to stop leak problem.

Not convinced, I brought car to my regular workshop in JB who specialises in BMW's. After diagnosis, mech replaced 2 o-rings at oil filter housing, and 4 more o-rings on the 2 VANOS solenoids. Viola! Oil leak no more and I'm poorer by less than RM270 - which includes my regular servicing. I brought my own oil, oil filter and air filter though....

And I must say that these guys are super pro! They even did a complete engine wash for me - meticulously cleaning EVERY item that has oil stain. Now my engine bay looks almost like new again! Hahaha!

If anyone here are feeling adventurous enough to head north to service your car, PM me for contact. Just to clarify, I'm NOT related to workshop in anyway. Just a happy customer after saving 90% of what the workshops here tried to charge me...

been driving around for quite a few months and realised that I need to top up 1l (as prompted by warning sign) every 3.5km is that still ok? or I should have the valve seal changed?

Depends whether do you want to drive for longer or scrapping soon.

If only left 1 year or so, then leave it be and top up as needed.
If still left a couple of years, then have it checked. It may not be the valve seal or it may not ONLY be the valve seal.

Leaks may be internal or external.
External - oil drips on floor after overnight parking. - consider changing valve body gasket, oil filter seal

Internal - no visible pools of oil even after overnight parking - can consider changing valve seal

Needing topup every 3.5KM is a serious issue, have it check with your mechanic!

Bro can pm me the wshop contact and address..
Thankz
 
Good morning everyone. Anyone has clue why my engine oil readings still showed 1/4 even after filtering out the oil and it is full 5.5litres. WS checked no leak externally internally. Also changed my sensor but readings still low. Anyone has similar experience?
 
Can PM the jb workshop and contact person. My engine oil gauge went down but checked oil still full. Changed sensor still same problem.
