ENGINE & TRANSMISSION
These cars came generally with the same Group 3 V8 as the HDT VH Commodore. Alterations included modified cylinder heads and exhaust extractors but everything inside the engine is pretty much Holden; simple to obtain and repair. Oil leaks are common but only need immediate attention if it’s really gushing out of a rear main seal. Look at engine and transmission mounts for cracks and perished rubber. New mounts at under $150 a set are worthwhile. Exhaust manifolds can leak and exhaust systems are prone to being crushed by speed bumps due to minimal clearance. The transmission is tough and cheap to fix if it does fail. Jerky upshifts are typical but a ‘box that slurs changes or takes more than a second to engage gears is due for a rebuild.
