I think so yes.I also had those problems, that now your are facing. Unfortunately I couldn't find any practical person to get a real advice.
These days Japanese engine prices are real high, Before u go for a jap motor please compare price with land rover 200Tdi engine. 200 turbo
direct Injection engine is the best practical motor land rover has ever produce. Other land rover secret is the center diff lock LT230 transfer box.
If u want to feel what is the land rover, least go for LT77 5 speed gear box with LT230 transfer box with compatible any motor. There r more issues,
But if u want to be a proud owner of a land rover, you have to live with those problems. Remember, LAND ROVERS & WIVES are same, so you have to,
cause its our passion. Have fun with your Landy........!
