Each valve has it's own 'port' where the manifold bolts down to, so I have 12 ports along the head. They diverge very close to the head in the inlet manifold. Most engines with 4 valves per cylinder I've seen have oval ports, the Mercedes just seems to have taken this to another level!
I was thinking about potentially using an OM605 with a Landy LT77/R380 in a future project (Baja MGB), but was wondering about towing with a clutch that can take the torque. Nice to see a high-rated single-plate clutch.
Have you towed with yours before? Haven't gone back far enough through the thread yet!
You can buy a bolt on adapter kit for the OM605/6 to R380 from a guy called Ollie North, he's on FB and is on the MercRover's group. Or go diy and fabricate everything yourself like I've done (there were no kits available when I started). Clutchfix do a higher rated pressure plate than will fit the Land Rover tdi flywheel (and rwd Rover V8) to match the 600lb/ft friction plate, rated to somewhere around 470lb/ft I think over the 414lb/ft HD pressure plate they normally supply (which I have for my other Rover). I've not towed with it, though you're more likely to have cooling issues under prolonged load. A V8 spec radiator on mine has so far been perfect throughout the summer, but with a few tons dragged behind, I'd be wanting something more than what I already have, maybe a 4 core rad?
