Worse Injection system, BEST engine

Certainly, though the early hot-wire (export market) is a bit cack.  Fortunately I've only ever seen one (yes, mine :evil: ).

That said I've never found the 3.9 to be any trouble.

Spacemud:
Well, now that I have filled it with oil and water; it's working and it isn't causing me any problems. This being the case, I reckon you are right the engine must be pretty good. The injection unit hasn't caused any problems for me either so I'm guessing that as it has been there for nearly 20 years it'll go on a bit longer.

Still VERY happy......................lets hope it continues!

jjsaul:
carb /efi changeover was 85/86

spacemud, if you have any questions or anything about it...just give me a shout - im not far away and have been using my lpg 3.5 86 RRC daily for 12 months so have had most things come to try me so far! lol

Ahh but.....
Yes the flapper system is a PITA at times but surely better than carbs for the LPG, well... unless you get a blowback and blow it to bits  :cry:
Considered swapping mine but for a single flat carb like a weber, HOW MUCH  Ã‚£Â£Â£Â£Â£  :shock:
The 3.5 has a better record for slipped liners and cracked blocks than the 3.9/4.2 but like said, let down in part by the flapper system.

Solution??? Buy a 3.9, slip a liner/crack block..... scrap the engine and fit a 3.5.  Best engine..... best injection set up  (hot wire) :lol:

Would the reduction in capacity require any retuning of the ECU tho??  :?

Change over was around 1986/7 C/D reg I think.... didnt Bosch have a crack at the flapper system before the Lucas unit?? I bought one by mistake when first got RR and was told it was a better system but can not be used with Lucas ECU.

Enough of my opinion for now
Creating more questions than answers  :roll:
