similar =Triumph Slant-4 engine The Triumph V8 is a 3.0 litreV8 developed in house by Triumph for theTriumph Stag . This was basically twoTriumph Slant-4 engine s 'stuck' together. It consisted of a single overhead cam cast iron block with aluminium heads.This engine can suffer from unreliability as a result of the following design problems:
*Overly long single link chains with poor tensioning that only last about convert|25000|mi|km|-2. The damage is extensive if they fail;
*Inadequately sized main bearings - these have short lives as a result;
*The aluminium heads warp due to poor castings which restrict coolant flow, leading to overheating;
*Water pump failures relating to the drive gear shearing.Many modern day upgrades and sticking to the manufacturers recommended service schedules help to solve these problems. An air dam for a
TR-6 helps solve a cooling problem by scooping up the air in front of the car. A 12 blade fan helps to pull more air though the radiator.On a side note the V8 was substituted for the Triumph 6-cylinder engine unit in the Triumph Stag. The Triumph Stag was originally envisioned as having the 6-cylinder 2.5 litre PI engine as used in the
Triumph TR5 .ee also
