Our engine rebuilds are thorough and extensive.
The engine is stripped to bare components and put into a high pressure wash at high temperature with cleansing chemicals, this removes all carbon deposits and debris from previous failures. From this stage the Cylinder bores and pistons are checked for cracks and wear tolerances. .
Pistons are checked and Rings are then changed, Connecting Rods and Crankshaft are checked for tolerance specs.
Each cylinder head core is disassembled and inspected for broken bolts, stripped thread holes and broken mounting holes, etc.; All heads go through a three-step cleaning process which includes:
- Passing through a high temperature oven.
- Professionally bead blasted.
- Placement in a non-caustic hot tank.
The Head is then inspected for cracks and is pressure tested. Cam bores are checked for spec and honed, if needed.
The machining process includes:
- Inspect valve guide bores using a dial bore gauge and repair where needed.
- New OEM German Phosphorous Bronze Valve Guides and Valve Stem Seals are installed.
- All valves are machine faced/replaced as needed.
- Thorougly inspect and test all of the valve springs for proper tension/resistance and replace as needed.
- All head surfaces are machined (milled), not ground!
Final head cleaning and assembly includes
Cleaning all heads in a solvent base tank in which all oil galleries, thread holes, etc. are cleaned. A number of different brushes are used to catch any remaining contaminants.
All heads are run through a detergent based hot tank before assembly. All assembly work is done by hand by Professional and Expert Porsche Specialists.
Carrera Style (Hydraulic) Chain Tensioners Installed
In 1984, Porsche began using chain tensioners that rely on oil supplied by the engine's oil pump. These new tensioners do not fail like the older chain tensioners often do. It's definitely an update that should be made to any 911 (through '83), or 930!

Engine Break in hints for the first 2,000 miles (3,000 kilometers)
The following tips will be helpful in obtaining optimum performance from your rebuilt Porsche engine.
Despite the most modern, high-precision manufacturing methods, the moving parts must still wear in with each other. This wearing-in occurs mainly in the first 2,000 miles (3,000 km).
Therefore:
- Preferably take longer trips.
- Avoid frequent cold starts with short-distance driving whenever possible.
- Avoid full throttle starts and abrupt stops.
- Do not exceed maximum engine speed of 4,200 rpm (revolutions per minute).
- Do not run a cold engine at high rpm either in Neutral or in gear.
- Do not let the engine labor, especially when driving uphill. Shift to the next lower gear in time (use the most favorable rpm range).
- Never lug the engine in high gear at low speeds. This rule applies at all times, not just during the break-in period.
- Do not participate in motor racing events, sports driving schools, etc. during the first 2,000 miles (3,000 kilometers).
- Perform the first oil change at 500 miles (800 kilometers), after that we recommend to perform oil changes every 5,000 miles (8,000 kilometers)
- We recommend using 20w50 oil on all air cooled engines.
