Engine/Car: 1990 R32 GTSt RB20DET with 240,000kms
Type of failure: Cracked Head
Factors influencing the failure: Old gunked up radiator, air con radiator also blocked up with crap. Engine overheated after FMIC installed.
State of tune of the engine: Mild, only exhaust and FMIC
Suspension and tyres: Bilstiens and Tein sprngs
Oil used and service interval: Castril Magnatec, every 5000
General comments: Overheated due to lack of airflow to already borderline cooling system. Was cheaper to replace engine than get a 240000 km RB20DEt rebuilt. Also got a new radiator and cleaned out the AC radiator and all runs sweet now.
