Engine rebuild and reconditioning services
At Peninsula Sports Cars, rebuilding an engine isn’t just about replacing a few worn parts — it’s about restoring performance, reliability, and the soul of the vehicle. Drawing on the expertise, knowledge & history of Mike Dyer Performance Engines our workshop has all the equipment, tools and expertise to deliver the same exacting standards as Mike did for so many years.
POWER RESTORED, CHARACTER PRESERVED – ENGINE REBUILDS FOR ENTHUSIASTS
Decades of hands-on experience in classic engine restoration and performance tuning
- Close to 60 years of Mike Dyer Performance Engines experience to draw on
- Full engine removal and rebuild services
- Vehicle pick up and transportation options
- Australian Ford & Holden 6 and 8 cylinder engine rebuilds
- Classic British, American & European vehicle engine rebuilds
- Extensive array of complimentary vehicle restoration & servicing available
Our rebuild process involves completely disassembling your engine, cleaning and inspecting every component, and then restoring or replacing parts to factory or upgraded specifications. From cylinder head servicing and valve guide replacement, to cylinder block honing and head decking — every job is done with precision.
We are an engine building workshop in Sydney that caters to car enthusiasts who choose to rebuild rather than replace because it preserves the originality of the vehicle and can offer better long-term value, especially for rare, classic or restoration projects.
“Darren and his team are 2nd to none with their knowledge, accurate diagnosis and passion for those that love their classic cars. The icing on the cake is great, friendly service with repairs done in a timely manner. Nothing is too much trouble and if they can't fix it then nobody can! I have used them many times and highly recommend you pay them a visit”

Our relationship with Mike Dyer, of Mike Dyer Performance Engines
Mike Dyer is a bit of a legend when it comes to engine building for race and road cars, and when I first bought Peninsula Sports Car Services I didn’t realise the path that would take us down. Mike’s workshop was next door, an absolute treasure trove of Australian motorsport memorabilia and a bit of a time capsule.
We started using Mike’s services for engine work and quickly built a good working relationship. When Mike decided it was time to close the toolkit, he approached me to buy his equipment and machinery, but I had a better idea.
To simply let Mike’s decades of engine building experience retire with him would have been such a shame. I asked Mike if he’d be willing to stay on and train some of our team in the art of engine building, so his legacy could be honoured and partly preserved.
Thankfully he agreed, and the rest as they say is history. We now have some of our ‘young blokes’ approaching engine building in the same tried and tested way that made Mike so successful for close to 60 years.
…and we are happy to report that Mike is now spending his days with his family, mowing the lean, cleaning the pool and all the other stuff retirees get up to.

When should an engine be rebuilt or reconditioned?
At Peninsula Sports Cars, we specialise in diagnosing engine wear and performance issues across a wide range of classic and performance vehicles.
If you’re experiencing loss of power, excessive oil consumption, smoke, or irregular engine noise, our team can carry out detailed inspections and testing — including compression and leak-down tests — to determine whether a full engine rebuild or reconditioning is necessary.
With decades of experience in working with Holden, Ford, and classic British marques, we provide honest, expert advice to help you make an informed decision about the next steps for your engine.

What engine components can we recondition?
The most common engine components that we are able to recondition include
Pistons or piston rings
• Worn rings cause blow-by, oil burning, and compression loss
• Pistons may be replaced if damaged or undersized after cylinder honing
Main or rod bearings
• Replace due to wear on crankshaft journals and connecting rods
• Critical for engine longevity and oil pressure
Gaskets and seals
• Full gasket kits used (head gasket, intake, exhaust, sump, rocker cover, etc.)
• Old gaskets harden and fail, leading to oil and coolant leaks
Timing components
• Timing chain or gears (and tensioners where applicable)
• Common source of rattle, poor timing, and engine knock in old engines
Camshaft and lifters for most types of pushrod engines
• Often show wear in classic pushrod motors
• New lifters and sometimes camshaft regrinds or replacements needed
Valve guides and seats
• Replace or machine due to excessive valve play and oil burning
• Often upgraded to hardened seats for unleaded fuel compatibility
Cylinder heads
• Decked to ensure flat sealing surface
• Pressure tested for cracks
• Valve regrind and seal replacement standard
Crankshafts
• Machined (ground or polished) or replaced if out of spec
• Checked for cracks and oil gallery cleanliness
Oil pumps
• Either replaced or rebuilt to maintain consistent oil pressure
Water pumps & thermostat
• Often replaced as preventative maintenance during rebuild
Welch (Core) Plugs
• Frequently corroded in old engines — replaced during teardown
Fuel and Coolant Hoses
• Cracked or brittle with age — usually replaced for safety

How do you know if your engine needs to be rebuilt?
Your engine may need to be rebuilt if you start to experience some of these common issues
Low compression across one or more cylinders
• Caused by worn piston rings, valve issues, or head gasket leaks
• Leads to poor performance and rough running
Blue smoke from the exhaust
• Burning oil due to worn valve guides or piston rings
• Common in older Holden red/blue/black motors and british a/b-series engines
Persistent engine knock or bottom-end rattle
• Worn crankshaft bearings (main or rod)
• Typically found in high-mileage Holden 202s, Ford 250 crossflows, and Triumph straight-sixes
Excessive oil consumption
• Engine regularly needs topping up
• Oil leaks and burning often linked to tired valve seals and worn internals
Milky oil or coolant contamination
• Blown head gasket or cracked head/block
• Common in overheated Holden and British iron-block motors
Overheating under load or at idle
• Can be a sign of cracked head, clogged coolant passages, or warped head deck
• Especially relevant for Jaguar SK straight-sixes and Austin-healey inline-sixes
Hard starting or rough idle (even when tuned)
• Caused by vacuum leaks, low compression, or valve train wear
• Seen in Minis and Mgs with tired a-series motors
Backfiring, misfiring or lack of power
• Ignition and timing issues due to cam wear, valve issues, or worn lifters
• Especially notable in Holden 308s and Ford cleveland v8s
Heavy carbon deposits on plugs or wet plugs
• Oil fouling from worn rings or valve seals
• Indicates incomplete combustion and oil intrusion
Visible external oil leaks from head, sump, or timing cover
• Hardened gaskets and worn seals
• Common with older pushrod engines and long-storage classics
Noisy valvetrain or ticking under load
• indicates worn rockers, lifters or cam lobes
• Particularly prevalent in Holden 253/308 and triumph ohv engines
Loss of oil pressure at idle
• Worn bearings or tired oil pump
• Especially risky for Rover v8s and older inline-sixes
