nope i use what weve got a work 205 litre drum of 10 40 semi from vw really good oil. its what ive used since ive had the car and i keep it changed every 1000 miles
its not big ends or anything to do with the pistons mate...... iv got the exact same problem with mine right now.
Iv forged mine myself with 75mm weisco pistons and scat rods, ACL bearings ARP crank bolts.. when i start the car from cold it makes a loudish tapping sound which is piston slap until its warm.
The bottom end is perfect as far as im concerned as the car runs very well, but when i give it a slight bit of throttle you can hear a tapping sound even when warm, iv narrowed it down to the top end for deffo. Its gotta be tappets or something like that but im still trying to work out what it is exactly.
Mine was never like it until i stripped it, it wont be your bottom end mate, if it was it wouldnt run properly.
but mine doesnt chuck out blue smoke mate
