147 GTA Clutch and a couple of other q's
Operating on the basis that the correct number of Alfas to have is always one more than the number you currently have, and having loved the glorious sound of the V6's that surrounded me on the way to Brooklands on Saturday, I went to view a 147 GTA today. I was pretty impressed by the car overall, but have a couple of questions for those much more knowledgeable than I on these cars.
Firstly, the clutch was very heavy, in comparison to the GT 3.2's I've test driven in the past. My assumption was that they would have the same transmission set up, so is this heaviness indicative of a clutch about to give up? There didn't seem to be any slip and the bite point seemed OK. How much might it cost at a specialist to sort this? I've seen the "known issues" thread about the clutch on the diesel GT being heavy - is this likely to be the cause of the issue on this GTA or do the clutches work differently on these models?
Secondly, are there any known oil leak weak spots on the engine around the rocker covers, or cylinder head? There seemed to be a small patch as I was looking at the engine, on the front of the front bank, to the right of the block. Hard to tell if it was old or new.
Third thing is valve clearances - does the V6 engine need these done at regular intervals? It's reasonably high mileage and it did sound like there was a bit of a clicky, tappety noise from the engine. Or, dos this sound like it might be something else that's "known" about these engines?
Finally, do the OBD ports only work when the engine is running?
All help greatly appreciated - was good to meet up with some of the South Central guys the other day and I have a feeling this site could be a useful resource for me in the absence of one of Haynes' fine works for any recent Alfas.
