    Hello. I have a Renault Laguna 1 Ph.II, 1999. I want to swap my F4P engine to a F4R. Problem is, the F4R engines in Laguna 1's are pretty rare... I assume that, considering Renault's habit of making things incompatible, means that the F4R engine fitted to other models would not bolt up to the...

    My engine temp guage rises quickly to just below half but then never moves any higher. I have checked true temp with independant means and the fan cuts in normally at about 85'. Anyone any suggestions? Also I struggle to achieve anything better than 30mpg - is this normal?

    As per title, is it possible? I've been having silly little day dreams whilst 'busy' at work. I see the F series has been turbo'd before, so is it possible to transfer the necessary bits over? I'm not after big figures, just a bit more grunt. It'll probably not happen, but if it's simple...

    Are 2.0 F4R & 1.8 F4P Camshafts the same ? I know the cylinder heads are the same and the cam shafts will be interchangeable. But I don't know if they both have the same amount of lift ?

    Hi all, Found out today that our Scenic with what I believe to be an F4P 760 engine has died. We're going to be doing a transplant to another F4P, but I was hoping someone could verify compatibility for me? I've seen a few 770 and 771 engines on eBay and want to know if this will be compatible...

    Hi Guys, Just got the rebuilt head back all bright and shiny, so hopefully this weekend I can start putting Humpty Dumpty back together again :) Just one question regarding the 'bullet' hydraulic lifters. Can/should these be disassembled for cleaning, and should they be 'primed' in some way -...

    Hi Guys, I'm looking at replacing the cambelt on a 2001 Megane 1.8 with the F4P-722 engine. I've only just bought the car, which has no service history(!), so I'd like to get at least one major 'unknown' sorted ASAP. It would appear that a few 'special' tools are required - crankshaft locking...
