Here's what goes into our Air Cooled VW & Porsche engine rebuilds

​

• The engine is stripped down to it's bare components 

• All parts are cleaned from oil, foreign particles and carbon deposits removed 

• All components are then checked for wear and tear and are compared to OE manufacture tolerances and replaced where necessary 

• Barrels are honed or replaced when necessary 

• All new big end, main bearings, intermediate shaft bearings, piston rings are used (pistons if required) 

• Engine components such as tinware, heads, covers, barrels, pistons are aqua blasted bringing that aluminium a new lease of life. (as seen top left)

• The cylinder heads, valves, valve seats & guides are recut and or replaced where necessary, then reassembled with new valve stem oil seals and vacuum tested

• All engines are built with all new gaskets, seals, head studs, and timing chains and genuine sealants.

Further to this there are various upgrades available naming a few below

​

• Oil fed tensioners kit (image top right) - this is a must for engines before 1983. Giving constant tension on the timing chains eliminating the early chain rattle 

• Bigger barrels & pistons - increasing displacement size and or compression ratios

• Uprated head studs - 993, Dilavar or RaceWare

• Performance camshafts - increase your air-cooled's personality

• Oil pumps from 1976 were modified to increase outlet oil pressure these pumps have 4 vertical lines as seen in image to left with green arrow

• Turbo valve covers - made from aluminium instead of magnesium these have reinforced ribs decreasing the likeliness of warping and causing prone oil leaks.

• Engine tinware modifications pre 1977 (image middle right) - This involves removing 1 inch of material on the centre baffle plates, to eliminate hotspots & overheating issues by increasing airflow around the engines. this is common practice as pre 77 engine do not have oil coolers

• Idler arms - from 1980 the bearing surface was increased to eliminate binding on the shafts extending the bearings lifespan

• 911 Turbo camshaft housing oil line restrictors can be used to reduce the excess oil flow to the bottom end therefore increasing oil pressure particularly on idle.(image bottom right)
