Goetze
Goetze for Porsche
Goetze is one of the longest established names in the automotive aftermarket, delivering technically advanced components that significantly lower oil consumption and reduce emissions. Our Porsche replacement components precisely match the same specifications as the OE Porsche originals. The pistons, piston rings and liners all work together to provide a reliable seal in extreme conditions. They help cut emissions by minimising friction, lowering oil consumption and prolonging engine life.

Choosing the Right Fit for Your Porsche
Where Goetze is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.
- Typical reasons to choose these parts include addressing oil consumption, restoring compression and improving oil control during engine rebuild work.
- Common real-world issues include oil consumption, blue smoke, poor compression, blow-by and fouled plugs, which can be linked to ring or bore condition.
- Ring problems will not fix bore scoring on their own – the cylinder condition must be inspected and properly prepared.
- Proper honing, correct installation and careful bedding-in with initial oil monitoring are important to achieve stable sealing.
Browse by Category
If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.
Engine Rebuild Parts — Typically used during full or partial Porsche engine overhauls where internal wear, low compression, high oil consumption, internal noise or contamination has been identified; renewing core components, gaskets and hardware while the engine is apart helps avoid repeat strip-downs and improves long-term reliability.
- Before committing to a rebuild, carry out compression and leak-down tests, inspect bores where possible and check the oil/filter for debris.
- Plan to replace hard-to-reach wear items such as chains, guides, seals, bearings and key gaskets while the engine is out.
Piston Rings — Focused on restoring compression and oil control in Porsche engines where tests and symptoms point to ring or bore wear; commonly replaced during rebuilds or top-end refreshes when there is persistent smoke, blow-by or unexplained high oil consumption.
- Use compression and leak-down results plus smoke behaviour to distinguish ring issues from valve guide problems.
- Always inspect cylinder condition and prepare the bore finish correctly before fitting new rings to ensure proper bedding-in.
