Custom Engine Rebuild Kits
Built Specifically for Your Mercedes Engine
Every engine is unique. Why would rebuild kits be any different?
Generic “one-size-fits-all” rebuild kits force you to hunt down missing components or pay for parts you don’t need. At Adsitco, we take a different approach: our Mercedes parts experts build custom rebuild kits tailored to your specific engine and rebuild goals.
Whether you’re a DIY Mercedes enthusiast or a professional shop looking to save time on parts sourcing, our custom rebuild kits give you exactly what you need—without the guesswork.

Why Choose a Custom Rebuild Kit?
Save Money
Custom rebuild kits typically range from $600–$2,000, compared to $18,000+ for a professionally rebuilt engine. You get quality OEM and OE-spec parts without paying for a complete rebuild service.
Save Time
Stop spending hours tracking down compatible pistons, gaskets, seals, and bearings across multiple suppliers. We handle the sourcing so you can focus on the actual rebuild work.
Get Expert Guidance
Our team has over 40 years of Mercedes-Benz parts experience. We’ll help you select the right components based on your engine number, current condition, and rebuild objectives.
Perfect for Shops

We specialize in classic and Mercedes-Benz engines. Modern engines have more electronic components and are more difficult to rebuild. If you have an unusual or rare engine, we’ll let you know during the quoting process if we’re unable to source certain components.
Bearing and piston sizes are independent. You can select different repair sizes for main bearings, rod bearings, and pistons based on your engine’s specific wear patterns and previous repair history. Our parts experts can help you determine the correct sizes if you’re unsure.
Yes. If your existing pistons are in good condition, you can order just the piston rings. Select “No” for pistons and “Yes” for piston rings in the form.
Not necessarily. If your existing camshaft is in good condition with no excessive wear, you may not need a replacement. However, many rebuilders choose to include a new or camshaft for peace of mind.
It depends on your current pump’s condition. Many rebuilders replace the oil pump as preventive maintenance, but if yours is functioning properly, you may not need a new one.
Prefer a Complete Rebuilt Engine?
If you’d rather skip the rebuild work entirely, we also offer professionally rebuilt engines ready to install with a 1-year unlimited mileage warranty. Rebuilt engines typically range from $12,000 – $25,000 depending on the engine model.
