  1. Valve Clearance when engine is hot

    Engine Repair, Diagnostics & Rebuilding
    Hi, I have checked the valve clearance of my 1974 GTV 2000 and I'm good when cold. I also checked when hot, right after 50 km drive and I expected lower clearance.

  2. 164 brake compensator valve

    164 & 168 (1991-1995)
    Hi, While preparing to pop in a more solid rear subframe have been trying to obtain a new brake compensator/regulator valve unit - without success. I think mine still works OK but makes sense to replace it given the pipes will need replacing anyway and will probably break when trying to remove...

    As per Jim K. one can use the BMW 325i production parts cause of the valve shape and 8mm stems. I've tried sourcing these today from a local parts store.

I would like to check the valve timing before starting the engine in case the timing chain...

  7. Valves for 1979 Spider - Please HELP!

    Spider - 105 & 115 Series (1966-1994)
    Hi, I posted this weekend about my saga with valves for my new tires and I'm now really in a pickle. The place I took my Alfa still cannot find valves for the tires - the wheels are the original and the tire store has contacted a number of places to get valves to fit. They have contact some...

    Before I head out to perform a valve clearance adjustment, I thought I'd post a spreadsheet I put together for calculating new shim sizes required to achieve correct clearance gaps. If there are errors, let me know and I'll update them. I tried to make it simple and easy to use. It includes...
