Thread: 16/20VE Shim Clearance

Any one have the idea for the VE head shim clearance

I measure the one at my head before is 0.35mm and 0.40mm

Feel it a bit loose side

i set mine to stock de clearance

sorry
i dont have the stock DE clearance info
anyone can guide me here ?

thank you

ill have to check when i get home, i think it's .15 intake and exhaust but maybe someone else has an FSM in front of them

The intake and exhaust will not be the same. The intake is alwasy tighter than the exhaust on a Mechanical setup or solid setup

i remember all 0.35mm on one side and 0.40mm on one side

forget intake or exhaust side

only can check it out tomorrow morning

my intake and exhaust are shimmed the exact same and when degreed my cams are perfectly on manufactured claims

Makes scence as the exhaust valves will grow more with the extra heat.

explain this to me

It is simple.

Exhaust valves are always hotter than intake valves.

I am sure you have never heard of anyone burning and intake valve when the car runs lean. When a car runs lean the exhaust gas temp goees up the exhaust air goes out the exhaust vales. These valves are subject to more heat as the intake valves always have cool air passing over them to cool them down unlike the exhaust valves.

As we know when things get hot the expand. So to keep everything equal during operational temps the exhaust valves ahve to have a little more clearance.
