Has anyone here had much experience with the Toyota 4M motors, carby version?

 

Are they as easy to work on as say, a Corolla 3k/4k motor? I am somewhat looking for Cressida or Crown which runs a 4M, but I don't want to get something that is a nightmare to work on, particularly seeing as my mechanical knowledge goes no further than a basic service on the holden V6's, and the 4AGE motor.

4M is pretty easy to service and maintain...

If you're looking to modify, that's a different story. 4M is kinda like a 4AC in that respect... Like polishing a turd.

Why go for a 4M. More than likely will need a rebuild.. Much better to go 1JZ, NA or turbo. 2.5 litres and so many options, also lighter than 4m. So easy to get 400+rwhp with a few bolt-ons without opening the engine.
