  1. 156 2.4 10V JTD Tappet clearances

    Alfa 147, 156 & GT
    Hi Guys, Can anyone help me out. I need the Inlet and Outlet Valve clearance figures on the 2.4 JTD 10V so I can check which shims must be replaced. The noise apart from the diesel rattle which i got used to is driving me crazy. Regards Tony
  2. Tappet clearances

    Alfa 33, Sud & Sprint
    Hi all, I managed to pick a 105 hp engine over the last couple of weeks with 40mm carbs and trofeo cams?? Checking it over and tiding it up I got to measuring the tappet clearances. Now with the earlier split cams on the current motor in the car finding the gap in the Haynes manual was easy...
  3. bronze bush to output shaft clearances?

    The Classic Alfa Romeos
    Whilst the gearbox was apart to replace broken dog gears, I discovered there was quite a bit of wobble and play between the pinion gears and the main/output shaft. The bush IDs measured between 0.004" and 0.009" over the related shaft ODs. I decided to replace the worn bronze bushes inside the...
  4. Alfa Romeo 3L v6 24v Valve Clearances?

    Alfa GTV & 916 Spider
    Hello, I'm in the middle of checking the valve clearances (and then changing the timing belt), but I cannot find the tolerances in my workshop manual. Hopefully someone knows this this is? :) Sanath
  5. 12v V6 valve clearances

    Alfa 155
    I have a terrible tapping coming from my V6, not sure if it is the cam variator or the valves. How would I know which is making the tapping noise? Also, my mechanic yesterday adjusted the valves to factory spec of 0.475-0.5 mm for the intake valve 0.310-0.345 for the exhaust. Just got the...
  6. Brake upgrades and wheel clearances

    Alfa 33, Sud & Sprint
    Hi Gents, Struggling with front wheel offset, due to the 17mm clearance required from a 16v caliper, 17mm being from the hub face, would be interested to know of clearance dimensions using different/modified calipers. Thanks Liam
  7. check valve clearances

    Alfa 147, 156 & GT
    Hi guys, just looking through my service schedule and noticed "check valve clearances". I plan to do as much myself as possible but I don't know what's involved with "check valve clearances", is that a physical check or a plug it in to alfa diag (or similar) sort of check? [email protected]

  9. valve clearances

    The Classic Alfa Romeos
    Having had a bit of a cam chain tensioner nightmare,now sorted out. I took a look at my valve clearances and found that some of the exhaust clearances are up to about .6o and the inlets up to about .50 i was going to take the car to classic Le Mans next week but am unsure whether these...
  10. Valve clearances

    Alfa 147, 156 & GT
    Hi All. I’ve got a 2001 156 Selespeed with 41,000 on the clock and it’s got a bit of noise from the top of the engine. It’s a kind of valve tapping sound that I reccon is a tad too loud, which made me think the valve clearances may need setting up. Can this be done on these or is it like the...
  11. Valve clearances on 1.9 jtd 8-valve.

    Alfa 147, 156 & GT
    Anybody know if this job actually needs doing on the 1.9 jtd 8-valve. Sounds like a job that should not need doing on an engine that has only been about for about 5 years. My garage has quoted a service including it but when questioned he seemed a bit surprised as well.
  12. 147 valve clearances?

    Alfa 147, 156 & GT

  15. Valve Clearances ???

    General Alfa Discussion
    This should really be in the Tech lounge, but seeing as it's not really model specific, I've put it here. What would happen if the exhaust valve clearances were too small ????
  16. Valve clearances

    Alfa 155
    Is there an easy way to check the valve clearances on your car, or do you have to remove the cylinder head and check them with the head off. I noticed on the link how to change your variator that the guy showed a worn out cam which in turn made the valve clearances incorrect. Mines now done 165K...
