[V8] V8 leaking oil... again... and again..

Wed May 14 14:36:11 PDT 2008

I have exact same problem with mine, along with rear main seal. Did all the seals with last timing belt. All I can say is my alternator will never rust!

Well, well... I can't say I'd be happy about your oil leak, but it certainly
makes it easier for me as I have suffered the _exact_ same problem for
quite some time.

Late 2006 I did more or less the same repair procedures you describe:
- rebuilt cylinder heads
- water pump/thermostat renewal
- replaced timing belt + all rollers and adjustment damper
- all oil seals including oil pump, crankshaft, cams etc.
After 200-300 kms I noticed oil dripping down to the right side under the 
engine.
Most probably the leak was there immediately after the rebuild as the oil 
tends
to accumulate first on top of the engine undertray before it reaches the 
ground.
The leak is not a huge one, but very disturbing. Additionally I have oil 
mist inside
the timing covers. The leak seems to position itself to the right side of 
the engine,
more engine oil on top of the alternator than on top of the hydraulic 
pump(none there).

Fast forward to 2008: I have now taken the timing department apart for 4 
times in
15 months to find the darn leak. I replaced the crank, oil pump and cam 
seals twice
to make absolutely sure they aren't the ones leaking. I used a drill to turn 
the oil pump
for 20 minutes to see that the oil pump seal is ok. I made pretty sure that 
all the lips
of the new seals were not running on the tracks of the old seals and so on. 
Still dripping.
(The problem with this engine is that you can't run it with both timing 
covers detached to
really see what gives.)

Before the head rebuild I had no oil inside the timing belt covers(some 
other leaks existed though),
so something changed during rebuild - I've been chewing following thoughts:
- head gasket leaking - I haven't checked, but I think there's a oil gallery 
running in the front at least
  in one head -> it could be worthwhile to re-tighten the head bolts a bit - 
on what basis or how much,
  I really don't know.
- this may be over the top - too much oil left in i.e. cylinder head bolt 
threads in the block
  or elsewhere resulting in a cracked block. I do tend to clean all the 
not-thru-going threads in an
  alum. engine, but it's been a long time since I did the rebuild and cannot 
be sure anymore.

Otherwise this drooling engine is running really well w/o any problems - 
have driven 10,000 mls
marking territory everywhere - very nice...

So, unfortunately I can't be of any help to you, but as my V8 serves as a 
winter car, the ABH will
be lifted out this summer for further checks and full re-sealing. I will 
keep you posted, please do
the same.

P.S. Maybe this problem exists only in Scandinavia, eh...
