So the motor is in! The RDS mounts worked great. I do notice the 300tdi is a bit angled in the engine bay upwards in the front - but after looking at a lot of other conversions this seems kinda normal, right? I couldn't have really gone much lower with the mounts on the frame rail.
I do wonder if the motor mounts I have are from a Discovery and not a D90 and maybe this is why it's higher in front? Installed it's lined up with the slightly lowered radiator (which now has about the overall same height as my old V8 unit at 17") and now I just need to figure out plumbing. Mostly no big deal, but I have a couple questions.
1) Will most any muffler shop have the flange to mate to my exhaust?
2) Will stock oil lines for a 300TDI work or do I need to get those fabricated?
3) The Denso aircon compressor (yup I like AC) has a funny flange on it to which the A/C lines are supposed to connect, which is completely different than what I had on the V8. See attached. Where do you find that thing?
