That's a bad ending, good luck mate you'll get there in the end I'm certain of it 👍👍🇬🇧🇬🇧

This is why I don't do M52 M54 head gaskets. Just change the engine - you can do it in a (long) day.

This is what can normally happens when those m52 and m54 engines overheating, they normally not blowing always a head gasket, they simply just pulls a headbolts or two out of the block!

So much RTV! Sucks about the stripped threads. I’ve done Timeserts on aluminum blocks and they take well if done slowly by hand, but it always makes me nervous. 😂

it's missing a camshaft cover for the intake cam

Is there a machineshop nearby? They might can fix the block😊 great video anyway, but that sucks

Time-sert would likely be best option.

Can't remember which engine that is, M52 perhaps? Anyhow, M54 are notorious for same thread stripping problem. There is an excellent comparison channel called Project Farm, he tests all the thread inserts,, can't remember which comes out top, but I think you are right, Timesert better than Helicoil. Too late now, but in case it helps another viewer, the pros who know these engines always test torque all the head bolts before pulling the heads off and starting any work/expense. In my opinion, and it is only my opinion, I think that buying a second hand engine and going to the trouble of swapping it in, is a gamble, because it is likely to have a lot of miles on it unless you are very lucky. So I think the only way to go for true peace of mind is get hold of a second hand engine and re-build it so that you know everything is good, then swap the engines. Down side, very expensive exercise. I have the same dilemma with my 2003 E46 M54B25 which is burning loads of oil, is it worth repairing the engine?

Helicoil? I think it should hold. Better than replacing the block for sure now that you’re at this point…

I want to contact you. I have a problem with the E39 engine

Makes me sick and pissed off too see some amateur off a complete idiot use that amount off RTV and uses way way way more places than it ever should be used on those areas and almost destroyes the engine with it if it got loose and got in both the coolant system and in the head.... hope that morron never get to touch at least these beautiful timeless and classic E39ns ever agian..!! And as far as the very sad situation with the head bolt nr 2 goes, i would try the cheepest and easiest way out first and try the time serts if the bolt thread whole in the block is not to be saved, before buying a new block or engine 👍 good luck and otherwise lovely car and colour!💯 havent had a m52b20 since my first e39 that i had from 2015 to 2019 but i sure miss it 😵

Really? Just change the engine? 🤔😏 Here's how a M52 is rebuilt in Malaysia folks: m.ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-fm3SchhT_jU.html
