1996 M104 to 1996 M104?
Hi! Brand new user here, this is my first post!
I've been lurking on the site for a couple years, and I've been watching Kent's YouTube vids, and I finally in November got myself a W140!! This is my first Mercedes, and actually my first German car. I got the car for a song, as it had the entire right bank of idiot lights on, it ran very rough and shifted very hard, one window wouldn't close, and one door wouldn't open. The body is in pretty good shape, but some things just don't work as well as they could.
I got rid of most of the idiot lights with a 10amp fuse, I bought a new regulator to get the window up, and I haven't attempted to fix the door yet.
More pressing is the misfire on cylinder 1. I've done research, and I'm leaning toward the head gasket. And that hard-shifting tranny.
I just got another '96 S320, things work on this one that don't on mine, and vice versa. It's a perfect complement car: The engine and transmission work perfectly, and the body is pretty shite. It seems like someone tried to lower the front end, but it doesn't really look too good. Doesn't affect the ride much, other than making the steering feel looser than the other car.
There are many many posts on here about switching out engines for more powerful ones, but here's what I want to know:
How do-able is it to take the M104 and 772.5 out of one '96 and plop it in another '96 that had an M104 and 772.5?
I am not scared of getting greasy, and have spent many years messing around with American cars. I have rebuilt OHC engines, and fired them up without getting a check engine light.
But I have also had a guy that works on Japanese vehicles tell me that if I switch these engines it'll never run again! He said, "It's a Mercedes, not a Chevy!!"
What do the Mercedes guys have to say?
Thanks in advance,
