My son's 2010 328i engine blew last night, we had pampered this car, regular maintenance, etc. The engine was purring just days ago. I have no idea what happened, metal debris (chunks) on the skid pan and oil everywhere. The shop just informed me that they can see a hole in the side of the block and are looking further. Needless to say, we need a good used engine, however, looking online and reading reviews a LOT are just scammers. Can anyone on this site recommend an honest contact for a used engine? Any help is greatly appreciated!

Low oil pressure due to oil starvation.
Did belt snap? These engines will suck in belt if belt snaps or tensioner fails. That happens bcs. old belt or tensioner, or OFHG leak on belt or tensioner.
N52 is not known to grenade just like that.
I would check local European indy shops. They might have contacts with junkyards.

Oil was fine, just changed a 1000 miles ago. All fluid levels good, again just checked a few days ago. I have checked local European shops, however most used engines have over 150K on them. I was hoping someone would be able to recommended a honest and trusted shop/yard. I can't find a single company online that has good reviews!

Yeah, it is not oil. It is usually belt that gets sucked in and blocks oil passages.

Don’t rush into it if possible. Ask around for specialized indy BMW shops. They should know trusted sources.

It isn't oil, to be sure. Usually, it's the belt that gets pulled in and clogs up the oil passageways.

If at all possible, avoid rushing into it. Inquire about specialist indy BMW shops. They should be aware of reliable sources. Check out the web, online or local stores in your area.

thanks - I've looked everywhere online, however as soon as I do a quick check on reviews its game over. I honestly can't find one single used engine supplier that has a good reputation.

An N52 engine can last up to 300000 miles or more, subject to how it's treated. Before you buy one, use a bore scope to check the colour of the valve train by looking through the oil filler hole. If it looks like it has a dark golden hue, the engine has not had frequent oil changes or the wrong oil has been used. Also examine the outside of the engine for leaks . If the engine has been shampooed, there will be tell tale flakey white deposits on the outside. Don't buy it.

If and when you do find an engine, remove the oil pan an clean out any sludge. Pay particular attention to the oil pickup and make sure it's completely clear and clean.

Wasn’t neglect - my son only had the car for six months. Just 50k on it, fully serviced bmw. Bought it form a 2nd dealer.
6 months out of 144. Previous history is unknown; service history is only part of the story, Unfortunately. Any used car warranty?

50,000 miles in 12 years, for what reason? There is more to this story, if only that sitting is not good for an automobile.

While I was in college, the Crude Rude Dudes rebuilt a 1948 Chevrolet Suburban Carryall. When we found it, it had been sitting for a very long time, flat tires sunk in the soil, rat’s nests. We changed the oil, turned it by hand, and drove it 25 miles home. In just a few hours it was pretty well disassembled, then rebuilt over the next months. We drove it to the end of the road in Canada and home.
