Help finding 528i head

Hi all, got the head of my 528i 2000 twin vanos motor after overheating it to find gasket blown and head with at least 1mm warp. Trying to find a cheap replacement and also how to determine the best way to confirm it is the right part as I have bought one from Gumtree of same model but it doesn't fit. Good chance I have a stripped head bolt too. Is that an easy fix. I have that other head for sale if anyone wants to buy. Thanks for any opinions on my problems.

You must post in the correct forum next time.

Find a shop that will sand down the cylinder head or do it yourself. Once the head is flat, it will work again.

As soon as you notice the vehicle start to overheat, you MUST pull over immediately.

Thanks for your reply, I am a 1st timer what is the best forum to move this to. Also the local motor place told me because such a big bow in the head even if shaved flat the cam's would be running on a curve and possibly brake over time cause of the load.

Sounds like bull****. Take it to a different shop. If the head is perfectly shaved 1mm it will work just fine.

You need to head to the e39 section of bimmerfest to get help. This is the f10 (2011+) section.

528i 2000 head issues

Hi all, I am a newbie at this so please bear with me. I cooked my 528i 2000 and have taken off the head to find blown head gasket and a warped head around 1mm gap in the middle with a straight edge on it. A local place suggested too much to machine flat it may have too much stress on the camshafts running on the bowed top side. Any thoughts on this. Also I bought a replacement head thinking it would fit cause it was from the same model. My bad. More idea's on where to get a cheap replacement and how to identify the right one by numbers. 1 more thing, how easy it is to fix stripped head bolt hole in alloy block? Just 1 stripped. Thanks for any ideas. By the way what is a tag? It's saying I can add 15.

Don't know about "tags."

Much has been much posted about renewing threads in the block. Do a search.

Use this as a part number reference: www.realoem.com.

You should have a M52TU engine, same as mine. Look up your vin # on one of those free sites and it will tell you your exact engine or bring your vin to BMW parts or service dept and they will look up the info you need free of charge. as far as finding a head, internet is always the best way to go or find a parts car on craigslist and buy the head. good luck

I think you need to look for a used engine. By the time you go through all the work and installing timeserts into the engine block, you still might not have anything that you can depend on. If the head is warped that bad, how bad is the engine block? Get what I'm trying to relay?

Thanks to all.

Thanks for all help. Absolutely better to get another motor, just trying to be stingy as we bought the car for $2k and don't think it is worth spending too much on it. Do realise that if it's not done properly it is not going to last. Catch 22.

By the time you get the head shaved and crack tested, buy gaskets, and sort out the stripped thread you'll probably be up over $500, and if you look around you can buy a used car with running engine for $1000. If you go to www.realoem.com and enter you're VIN you can find out your engine model (go into "short engine" and look a the table at the bottom) - eg mine is a 286S1. If you click on the part number on the right you can see what cars it was used in, so you get one of those. When you buy double check the engine is correct by looking for the this number is stamped on it - it's on the inlet side down low, not far from the engine number. The correct engine will bolt right in.

Did look into buying another car to swap motor. Didn't find anything in a hurry. Now I have unregistered it so I think I might just keep looking for something like that and take my time. As an extra any ideas on opening the boot without the battery hooked up. I thought the key would do it manually. Not the case.

Problem is I live in Australia and very hard to get parts unless you buy second hand or spend a fortune.

Connect a battery to the jump start terminal in the middle of the inlet manifold (under the bonnet) and open as normal.

Is this a question for me? I didn't buy a replacement head, I had the one from the car crack tested locally. No cracks found and it was already flat, so no remedial work needed.

I wouldn't ship a cylinder head from the US unless it was very special and you couldn't get one here eg a super high performance version of some sort. The freight is way too expensive, plus returns are too hard if something isn't right. Am sure you could find someone in Australia to grind a head for you. The place I went to in Sydney would do it for you I expect.

BTW if it really is warped a full millimetre you may not be able to grind that out. As I recall the head gasket for the ground head isn't that much thicker.

Gaskets and head bolts I bought online from the UK somewhere, cant remember where but I could find out for you.
