Running an M52 engine vertical
As space in my engine bay is at something of a premium due to the fact I'm using a BMW M52 lump, I was wondering if it was run so that the block
was vertical as opposed to at it's slanted angle, what would the repercussions be? Would I end up with oil drainage issues? This would free up
some much needed space on the drivers side and help centralise weight distribution - it would also cock up gear shifter location and gearbox mounts,
but that is manageable.
Hopefully someone in the vast knowledge base of this forum can advise me if this is just a diabolical idea or not

Doesn't sound like a good idea to me and will likely create oil pick-up / drainage issues as you say. It's also goig to make it incredibly
high and I doubt you'll see over it 
What issues are you having? I've had the M52 sat in my Haynes chassis OK. Yes it's tight but it all looks do-able.

As you say, I would have thought that oil pick up and drainage would be an issue. Pick up could probably be sorted, but I would imagine that drainage
back to the sump might be more of an issue. You would also either be making the lowest point of the sump too low or making the top of the engine too
high as the sump is designed to have a flat bottom with the engine tilted to the correct angle.
I got my engine in by cutting a bit off the side of the sump, in that way crank shaft is about an inch to the left of the centre line of the car -
every little helps and you need an angle on the prop shaft anyway.

Thanks for the replies guys 
Nick: I hadn't thought about the height - that would be a bit of a bonnet bulge! I'm not having any issues in particular, it's just
going to get awfully cosy with the steering column, brake cylinder, clutch cylinder and exhausts wanting to occupy that side of the engine.
Steve: I was considering making my own sump, I've currently got a butchered original sitting in place. Your solution looks very interesting,
but is it not still rather low? I'm trying to make sure things don't go below my chassis rails, the only exception being the lower part of
the bell housing.
I've been playing around with the idea of making a dry sump system for it, but haven't gotten that far yet! I want to get the steering,
suspension and brakes sorted before I get started on the engine systems.

You're exhaust may need to go up or out rather than down. The std manifolds bolt on pointing upwards and will poke out of the side of the bonnet
if reqd

It does sit a little bit below the chassis rails, by about an inch, which isn't ideal but I've seen plenty of other engines like that. I
did end up with a little bit of space between the underneath of the bonnet and the top of the engine, so I suppose that I could have raised it a bit
(but not by the full inch).
I was worried about how I was going to get the exhaust manifolds to miss the steering column, but in the end, it wasn't a problem:

Of course, my Viento has a bigger engine bay than most, so I had more room to play with.
BTW I also had to extend the gear lever back a bit to avoid it hitting the dashboard in 1st, 3rd and 5th.

Hi again ppl, putting the same 2.8 bmw engine in and was just wondering what the height is of the bonnet above the chassis? I am looking to get one
from equinox or similar but just so I can work out where to place the engine. I have seen Steve Wallaces adaptation to the sump and will be looking to
do the same alteration.
Many thanks
