I keep telling people about it, and now I have to do two headgasket jobs on two 535i.

The heagasket was damaged around cylinder #6 (as always).
The water passages holes were cracked on the headgasket (I will take a picture).

And on the 535i you also have to check that the oil spray bar bolts are tight and not loose (or gone). The camshaft will be damaged anb will need to be replaced: around 410 Cdn or so.

Just my 0.02c.

I am a strong believer when it come to OEM coolant.
trust me the crap that I flush out the coolant. man is nasty.
you might pay a little extra more for oem coolant. but in the long run it save you from head gasket.

Just bought 20 jugs of BMW coolant, I always use BMW coolant mixed 50%- 50% with distilled water.

Considering that you change your coolant every two years (the same applies to brake fluid, every 6 month if you go to the track). The extra cost of using BMW coolant is really minor, compaired to 1300 Cdn you will pay for a head rebuilt and headgasket replacement.

Has the price come down; I think it hit something like 40 bucks a jug?

It is cheaper than that... I think they had a mistake in their computers for awhile. And the guy told me that it was because the price of the coolant went up... YEah right, like if it was traded on the stock market.

Should be around 23 - 25 Cdn or so / jugs. Gotta love that blue stuff.

BMW recommends rad flush every year, and brake every 2. Small price to pay for engine longevity.

Good news - its time for a rad flush in a couple of weeks

New bolts are $9 ea, they come with some loctite on the thread. To make it even better some people drill a 1mm hole thru the bolt head and use steel wire to secure bolt to the oil rail. New bolts with loctite on the thread have a circle on the top of the head. This is the "must check" thing.
Let us save M30.

That engine was extremely dirty. Does it worth fixing?
