Good luck Nick!!

Definitely going to be watching this. Thinking about going the same route as you. M42 is boring and I'm still in school so don't haves big enough budget to do an s52

Thanks! I'll keep it updated best I can.

Looks like you're making great progress! Did you get a leak down test done? Never be easier than it is right now to do a HG replacement...I'd still consider that, were I you. Peace of mind really is a beautiful thing

Nope this weekend when I make it back up to the shop. Hoping for the best, sort of prepared for the worst. Haha.

Nice!! Sub'd. I also just began my M50NV swap. I like the simplicity of this set up. Keep posting the good work.

Thanks I'll try 8-)

Stuff came.

This is awesome! I've actually been researching m50s + G240s earlier and stumbled across your thread. This is exactly what I'll more than likely be doing to my m42 as well. Your m42 bay is amazing and thanks for the sunrise red info! I need it bad. lol

Nothing particular to update other than painting and cleaning parts is going well. Pretty happy with how these have turned out.



Pulled the tensioner pulley apart as I didn't want to buy another and it was seized. A few minutes in a vice and some penetrating lube and it moves freely again. Pulled the bearing shields off the pulley and cleaned and relubed those, spins smooth. Cleaned and painted.



Engine arms also hammer finished and thermostat housing wrinkle finished.


Working on stripping the valve cover but paint stripper isn't liking this strangely cold Ohio weather. It snowed this morning . Not cool Ohio.

Going back up to the shop this weekend and painting the block and hopefully getting it mostly back together. By next weekend I'd like the engine done so I can start pulling and prepping the car.

Honestly man once you do the swap, simplify the bay etc, yanking these motors back out is a joke. I can have the motor back out of my car in an hour. Its cake. So if the case was that the headgasket was shot, its just a day project to throw another m50 in. I say rolling the dice isnt a terrible idea as long as you have a daily which I think you do haha? It could end up being fine.

Yup, have an E34 wagon for a daily. This car sits most of the cold months anyways. That's sort of what I'm figuring. Best case, this engine is fine. Worst case, I replace it again in the spring. Either I'm truthfully OK with.

Right, same. When I did the upper gaskets in my M42 last winter I had a fair amount of similar looking sludge in the breather hose and up top. After it sat for awhile working on it some of it had made it's way to the pan but I change it regularly and haven't seen a bit of it since. Being this is a $250 motor, I may roll the dice and just keep an eye on it. Worst case, I buy another M50 and at that point will be a pretty basic swap. Still going to do a leak down test and make sure it's atleast somewhat healthy.

Good call.

[Nick_S]

Also I will tell you that my S52 had a very very very small amount of condensation in the motor up by the vanos under the valve cover, but no where near that much. That's why I'm concerned.

The pictures make it look much brighter than it was. It was pretty faint. Friend of mine said he thought it looks like condensation? Sometimes if I do alot of short drives and dont let the oil totally warm up I'll get the same colored sludge build up. Either way, it does concern me. Any real way to check without pulling it? We were going to do a leak down test this week.

I just spoke with my buddy who's shop I'm at. He seems to think that if the head gasket were bad, all of the oil would have been discolored, not just the stuff at the very bottom. Said he thinks it's just a sediment of metal solids normally in the oil but had settled to the bottom. I did also notice the pan had been damaged and looked to have been rewelded somewhat recently.

I suppose you're right, but I'd buy myself the insurance and just do the HG while it's out of the car. Sucks, but you don't want to drop this thing in only to find out it was blown. It would also suck to buy an M50TU when you have all of these parts for the NV, but damn. I don't know what to tell you other than I'd spend the extra money and have the HG done.

Was going to say when the e36's I buy need a new motor that's where I go. I've negotiated to 250$ with them too. If I were you I'd go have a look personally because sometimes they have no clue what they're talking about. There might be a NV one laying there.
