• Coolant or compression leakage
• Valve-seat damage
• Cracked head
• Injector-sleeve leakage
• Camshaft bearing housing damage

🛠️ Service Notes

• Check what the kit contains against what the job needs before you start, and use every part supplied — the sealing parts in a kit are matched to each other and should not be mixed with old ones
• Clean the head and block faces without scoring them, and check both for flatness and for cracks before anything is assembled; keep debris out of the bores, coolant passages and bolt holes
• Tighten in the stages, sequence and torque-plus-angle steps given in the workshop manual for your engine, with threads and faces prepared exactly as that manual specifies, and renew head bolts wherever it calls for it
• Refill and bleed the cooling system, then carry out any retightening or valve clearance recheck the manual requires after the first running period
