valve clearance

[arjunior45]

which is the operating valve clearance {cold engine} for an oem engine?
I thought it was 0,35 mm for the intake and 0,40mm for the exhaust, but today I saw that Q4's workshop manual mention 0,36 - 0,44 mm {intake} and 0,46 - 0,54 mm {exhaust}! So probably my 'clearance' is not the one that should be.

Mine are set as per the manual (which is as you quoted above) - I think you should check these out ASAP. Inspect your exhaust cam closely as they are known for wearing out the 2-3 lobes.

As Jack states, I set mine in the middle (or as near as possible) at 0.40 and 0.50 respectively.

thanks guys, I'll check clearance asap, when I'll replace the chain.

Wish it was a chain...far more piece of mind :biggrin:

You do know that someone in England has a classic Mini with a chain {a proper chain}, don't you?

There must be a way to have a chain in Alfa too. Maybe someday ...
