Vertically Mount an M42

[AndrewBird]

I'm trying to put an M42 in my MG, however, I'm running into some clearance issues. Most of my issues will be resolved if I mount the engine vertically instead of diagonally (valve cover level, not intake level). Obviously this makes the oil pan not work, but I can make a new one, along with a new pickup.

Is there anything else I'm not thinking of that would be an issue?

Oil drain back in the head????
sounds like a fun project....!

Yeah oil drainback could be a problem. Also the front coolant pipes will be off by a bit, which isn't that big a deal but may cause bleeding issues.

[AndrewBird]

I thought about the oil drain back, but as long as it is level, I think it should be fine. I haven't pulled the valve cover yet to look. Are the drain galleries on the lower side of the head only?

I love your MG. My grandpa has owned about 3 MGB's in my life time and they are fun. I think it would be so cool if you could get this to work.

Even something as simple as measuring your oil with the dipstick becomes a bit of a guessing game too. If you're using the M42's tranny, you'll have to keep the tranny level, which means making new tabs to bolt her up.

[AndrewBird]

Dipstick would be modified to work with the new oil pan to read correctly, so that isn't a problem. Tranny could be an issue, but at this point, I'm not sure if it will be rotated enough to matter. I still have a lot of stuff to look at and figure out though.

Hay! Hay you!


any update?

[SpoolnDaapex]

Have you thought about swapping a different motor? Seems like a lot of work when there are probably other options.

Almost perfectly level, but then again its dry sumped....

Transmission angle?

You can make a flat bottomed pan and dry sump the engine. You then can lower the motor another inch or two.

[carnurd]

Tranny angle would need to be corrected with either some type of adapter or a whole new bell housing..

[Massive Lee]

^^^I think an M20 bellhousing fits the M42 block. To be confirmed. If so, then get one from an early 528e with two-piece tranny. You can cut the end of that bellhousing where it bolts to the tranny (four bolts), and fabricate a new one, that will be rewelded at the proper angle.

Rotate the motor, but raise one side of the car up with super long springs.

^ or bag it and just raise one side if its showing symptoms
