Mine has piston slap from cold taggy, common with forged builds, as the pistons expand a fair amount when they warm up. Mines still going strong after about 18months of hard hard abuse!
Look forward to seeing the car at japfest!
Easily have it done, we stripped my engine one night, and rebuilt it in another, including valve stem seals etc, We did finish at about 4 am though! Did you ever find the cause of the problem Taggy? Look forwards to seeing this again!
Toyota red last year wasn't too expensive, this year I went and they wanted a fortune!! So this year I've been using red coolant from my local motor factors and mixing it with water 50/50. (Make sure it's the red stuff and not pink or blue)
