Thats odd, those are coolant pipes under the TB. Maybe some debris made it up there or something shot off the belts and slashed it?
My spare parts would be sold as complete. What i have,
3S-GE Gen 4 Head
8x Exhaust Valves (still installed, Complete with Shims and Buckets)
1x Exhaust Camshaft
1x Inlet Cam Pulley
1x Exhaust Cam Pulley
So out of that, you would need;
8x Inlet Valves (plus shims and buckets)
1x Inlet Camshaft
Its my old head so those parts you need are what broke when i had to fix mine. I just bought a complete head from Chisiang :)
To make the head complete,
camshafts are £219 each (but you can use your one)
head set £107 (this inc. EVERY gasket for a head off rebuild inc. Head Gasket)
cambelt £27
head bolts £7 each
inlet valves £15 each
buckets £12 each
shims approx £9 each (loads of sizes)
TBH, you need to take your head off and see what needs replacing.
As you have a Turbo, you could lower the CR (compression ratio) using a HKS Head gasket. Proper way to do it is to do Rods/forged pistons etc... This way you can up your boost from 0.5bar to as much as 1bar, but more boost doesn't always make for an efficient system, not sure the Greddy turbo has much headroom tbh..
Crack the head off, find out how many and which valves are bent, and if you want to buy my old parts as spares or just to work on then let me know!
Maybe he meant to say steam rather than smoke :P
I don't get why it detonated with 0.5bar boost, maybe its very badly tuned :winky:
