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

Repair shops can spend less time researching part numbers and more time doing billable work. We’ve already done the parts cross-referencing for you.

Frequently Asked Questions

How long does it take to receive a quote?

Most quotes are completed within 2 business days. Complex or rare engines may take slightly longer if we need to source specialized components from our vendors.

Do I need to pay upfront?

No. We’ll send you a detailed quote first. Once you approve the quote, we’ll send a secure PayPal payment link for full payment.

Can you help if I’m not sure what size pistons I need?

Absolutely. Our parts experts can guide you based on your engine number and current condition. Include any known measurements or concerns in the notes section of the form.

What if I selected the wrong piston size?

No problem. We’ll verify all specifications during the quoting process and contact you if anything needs clarification before finalizing your quote.

Do you ship internationally?

Yes, we ship worldwide. International shipping costs and estimated handling time will be included in your custom quote.

What if I need to modify my kit after receiving the quote?

No problem. We can adjust your quote to add or remove components before you commit to payment.

Is this service available for all Mercedes models?

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.

How do bearing and piston sizes work?

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.

Can I get piston rings without pistons?

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.

Do I need to order a camshaft?

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.

Do I need a new oil pump?

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.
