Can I just point out to any new members reading this, that Dagrad's bad luck really is an isolated case.
(Sorry Andrew I know this doesn't help you much)
I still stand by the reputation that the M47R engine is "bulletproof" more reliable in fact than it ever was in the BMW 3 series range.
(they were tuned to 150 BHP with a Variable vane turbo which has a poor track record of turbo fins breaking off & getting ingested into the engine !!)
Not the case with the 116 & 131 versions in the 75 ZT's
