That was 3 months ago. The clutch is juddering in first gear when the engine is running on e10 fuel but is much better, hardly noticeable when running on e5 fuel.
Do you think the clutch is just bedding in, a poor clutch or should I just fill with e5 from now on?
Done almost 1000 miles since rebuild and the engine is super smooth.
Yes clutch judder on first pull away, more noticeable on a steep hill when slipping the clutch. Not so evident while the car is running in e5 petrol. Maybe due to having slightly larger pistons as it’s had a complete rebore?
I’m thinking, although car runs great on E10 and doesn’t hesitate or stall but needs slightly higher revs than running on e5 when pulling away from stationary. So more slipping of the clutch to refrain from shooting off
Maybe it’s not the clutch it’s the engine telling you to use E5 petrol. My last NC had a remap to 180, totally run better more evenly at low revs and idle on E5 than E10.
I completely rebuilt my 2.0 NC1 sport motor and used a new 3 piece Exedy clutch.
Apart from the clutch feeling lighter than the one I removed - they operate exactly the same on E5 or E10 fuel.
Just to update on this weird problem. I had driven 1000 miles since the engine rebuild so I decided to change engine oil and filter, unbolting access panels for better clearance and inspection. I did find 2 lower bolts which hold the gearbox to the engine quite loose not even finger tight! Now everything is back together, and bolts tightened the problem with the clutch has cleared.
