N52 valve cover

[80stech]

It appears the Elring valve cover is made in China so andrewynn can order one and let us know how it looks. If the included gaskets are as good as BMW's (neoprene) then that's a pretty good bonus!

For a savings of more than three whole kit including screws and seals I'll be jumping on the grenade and let people know. Plenty of high tech made in china including the iPhone I'm typing on.

Do you know where the company blaupunkt got their name? Some company would put color dots on their equipment going through QA to m grade how well it was made and apparently the blue dot was the top grade. Blue Dot (blau punkt) somebody tapped into that and made a company based on that concept.

Here's where it gets a little ironic:

Ever wonder why almost every pencil on earth is yellow?

Back in the day when people were still trying to figure out how to hold graphite together it was there Chinese who figured out the best solution and probably because it was cheapest to use yellow pigment for the paint (same reason to this day construction equipment is largely yellow), the Chinese pencils were yellow and those worked the best. It got out people only wanted the Chinese yellow pencils and then everybody copied China and made their pencils yellow.

The "source material" for those history bits is my aging brain so I would do a little research on your own before spreading too much mis-memory.

Here's hoping my china VC will come with a blue dot and painted yellow.

Yellow prob made from lead. Kids chewing pencils prob reduced the average IQ by 10-20 points. Now that we got rid of the lead *on* our pencils, and in our gas we use tik tok (also Chinese) to do that job

The valve cover for the N55 looks entirely different but I guess should be the same for quality comparison. It's pretty cheap and almost too good to be true especially if the gaskets are good. I've tried 2 non-BMW gaskets on the M54 and neither lasted a little more than a year and I'm getting 5 and 7 years and still going with the BMW ones.

I'm planning to have this e70 for six years or so. I'll be posting updates that matter

I'm ~2 years into an $86 Amazon Bapmic valve cover, including gasket, for the N52 in my X5. No regrets here. I had trouble with gaskets leaking. This transitioned to PCV failure and intermittent loud whistling noise. $86 fixed both issues. Drivability improved also. Bapmic is the name that was on my OEM valve cover. Covers looked identical.

I bought a similar cover for my N54. Hope to install it soon.

Wow, that's again a fraction of the price of the Elring one! Did the gasket feel like neoprene, not spongy or hard like some of the cheap ones?

So Canadian Amazon has covers at about $160 cnd with mixed reviews, most are positive but one review says that the material can't stand up to temperature while the ad says that it's temperature resistant to all weather conditions Anyway, there appears to be an aluminium update version that looks like it has a serviceable PCV valve and passage ways!

It seems that with E70 they are saying PCV valve and not CCCV so that's interesting as well.

There is a YouTube video of a guy testing then diaphragm by putting vacuum to the top nipple and holding his hand over the big fitting so that would suggest that the nipple is actually vented to the crankcase making it a PCV system and not closed like the M54

I couldn't resist ordering the aluminum cover from Amazon and a spare PCV valve so that's on the way! The cheaper of the aluminum covers looks like it uses the same type of valve cover gasket in channel like the original (but has no reviews) while the more expensive one has reviews complaining that the gaskets are flat and there is no channel making installation difficult.

Which motor for the aluminum cover?

N52, I didn't check for your N55 but I imagine it should be available as well.

I think I'll stick with FCP for the warranty but mm definitely intrigued
