Valve cover gasket

Hi,
I recently bought a used 328i 2007 with 57000 miles on it. The car has an occasional burning oil smell (for 5-10 seconds) that I have probably got 3-4 times in a period of 10 days. I got the car inspected by a mechanic - who looked at the engine bay and said that there could be a VCG leak. The past history of the car - The previous owner did not have the oil changed for around 4000 miles - and only topped it as the levels went low. I topped it with a quart 4 days ago and have driven around 400 miles since then and level has been at the max level only.

The car is otherwise not giving any trouble - city mpg is close to 22 and on the freeway recently got a 35.3 mpg (saturday morning on I-10 from houston to san antonio).

What would you recommend to make sure that it is a VCG leak and nothing else with the engine. Should I get a compression test done as well just to be sure. I was going through the forum and am expecting the cost for the VCG to be close to 200$ in Houston.

Also Should I get an extended warranty for the car to be on the safe side?

Would really appreciate your response.

Thanks

SK

Congratulations, it's a great car. Valve cover gaskets do seem likely to fail and cause oil to leak onto hot surfaces -- you can do a search here and find more details. Oil filter gaskets also fail, with similar symptoms. It would be interesting to know if there is any serious oil loss or consumption. The manufacturer's recommended oil change interval is dependent on operating conditions, but generally is about 15,000 miles or once a year. It is important to use synthetic oil and to follow the manufacturer's recommendations for type and rating. I can't speak to extended warranties -- I bought my car new and don't have one.

Broken valve cover and Head Gasket bolts are common

Broken valve cover and Head Gasket bolts are common or at
least one of the more common problems on the N52 engine
Because they are made from aluminum due to the magnesium engine block.
Also there is a gasket on the Oil Filter Housing that is a common problem.
There are threads on this if you do a search.
If you are interested in maintenance google Mike Miller BMW for a old school maintenance
schedule and BMW maintenance history.

Also if there is a leak he should be able to see it.

Thanks - really appreciate the input. It is reassuring to know that at least the problem is a known issue with the bimmers. I will search for a good BMW mechanic as the authorized service centers are way too expensive. I did see a few video links posted on this forum but I guess will stick to going to a repair shop as I do not have tools and plus it would be too much for a first timer to directly take this complicated case as a lead surgeon.

Here's a procedure for the valve cover gasket; here's a procedure for the oil filter housing gasket.

Give 'em a read - at least you'll be prepared to discuss the issues with a mech.

You can do these - if you have a place to do it, guessing time's the issue - first time procedures usually go long. Hey - let us know what the resolution is....

-------------------------------------------
What was I thinkin'? N52 cover's a bit diff than N54 - here's a procedure w/bonus eccentric shaft sensor DIY for N52 jockeys.

Oh. I didn't know that this applied to only the N52 engine. I thought all this the valve gasket leak applied to the N54?

My gasket was replaced twice and the second time, they changed the cover. 1000$ job. Don't be fooled by the color in the pic - it is PLASTIC,

Thanks Saintor - i will post a pic of my engine bay later today - i know all the stuff under the hood looks clean but what lies beneath is all that bothers me. The feel of the burning oil is something that is growing up to be a nightmare.

most likely just a gasket leak on the turbo or exhaust manifold,
doubt its anything internal to the engine

the hard part is getting to everything to take the valve cover off, it appears, you might as well replace the spark plugs while its being done too

The broken head bolt valve cover bolt doesn't apply to n54

The broken head bolt valve cover bolt doesn't apply to n54.
But it has its own set of problems .
I have read the gasket for the oil filter housing is a universal BMW problem though.

It has failed on mine. That was fixed on my last service which was a couple of thousand miles ago. Then I had to bring my car in because it said it was due for service and while checking over the vehicle, they found that the oil pan gasket was leaking. Not a cheap fix that's for sure.

would you recommend getting the oil cover gasket and spark plugs to be replaced alongwith the valve cover gasket? the car has 57000ish miles and the on board computer doesnt mention about replacing the spark plugs anytime soon.
thanks

BMW says the plugs are good for 100k miles on the N52; 45k miles on the N54/55 turbos. I'm planning to replace mine at 60k just to make sure they don't seize. If I get to put in another set at 120k miles I'll be a happy camper knowing they are likely the last set I'm buying.

By the way, there is no correlation between the plugs needing to be serviced or the valve cover leaking. Those gaskets commonly leak; almost every make and model I've had developed a leaking valve cover within 100k miles. Some do so sooner, some later. It is what it is. Replace it and be done with it.

These are the pics of the area around the gasket
Does it look like there's a leak anywhere?

I'd say most of the discoloration in pic 2 is from the oil filter cap not being sufficiently tight...

Mein Auto: 2009 M3 & 2010 335i Coupe
A few days ago, the local BMW dealer fixed my 2010 335i Coupe's valve cover gasket under manufacturer warranty. What makes me un-settling is that my 335i has only 35k miles on it. From other threads I read, some claim that this job cost around $1,000 and the leak happens more than once during their ownership. In another somewhat related thread (http://www.e90post.com/forums/showth...=181743&page=6), it describes an extended warranty on BMW N51 SULEV motor emission related component, e.g., fuel pump, valve cover, exhaust, fuel tank. I wonder if any one knows if there there a similar BMW extended warranty for N54 engine?
