Porsche 964 Full Engine Rebuild
Engine and gearbox removed from car
Longterm oil leak mixed with dust from the clutch makes for quite a mess!
Much improved after a steam clean
Engine also cleaned to make strip down a more pleasant job
Into the clean room for tear down
Cracked Inlet manifold bases
Seized fanbelt sensor - note witness mark on fanbelt.
Broken Headstud!
Corrosion to Rocker Cover
Loose and missing pulley bolts!
Broken mounting lugs on fan shroud
Missing exhaust studs
Badly coked exhaust valve stems mean engine has likely been burning more oil than it should.
Engine tinware corroded
Broken headstud (second in top left) has been allowing gas to escape, note blackened area.
And again blackened area on righthand cyl head.
Exhaust is servicable but not pretty!
Damage to timing chain guide has left debris in the case and oil pick up.
Worn bearings
All in All no major damage and all easily fixed with a regular rebuild.
