porsche 911 engine - teardown 3











Ok, this was a sad day...
i dismantled the block to see whats wrong...my idea was that when
aarnio racing decided to swap my parts from my 68 S-block (without asking me first...)
to a 2.7 block (i didnt know anything of the 2.7 block except it turned and looked otherwise pretty ok to me...) ...i thought from the beginning that the bearing line would be twisted OR there would be something wrong with the bearings...BECAUSE i had my 2520cc screamer running years ago.
and the crank was athe machine shop for inspection, but they said that its in std size allover, and they dont do anything to it, because theres no need.
it was a 66mm porsche 911 S crank. it came in the block with correct S-rods as well...

ok, you get the hint. its not the same crank anymore. the S-crank is turned to a normal crank...

so where the HELL is my S crank? ...i´m getting mad! (and maybe to the police officers...)
hmmmm, i wonder whats the price for those crank´s in std size? any ideas?
oh well, i was partially correct, when i loosened the bolts of the block, the engine started to turn again...let me think...the pistons and cylinders are also gone, there has been so much dirt when the engine was "rebuilded" that could have been making the really deep scratches on the pistons and cylinders. ...well this was the saddest day in my porsche hobby, BTW i originally bought the S-engine in 1988...

to be continued...

porsche 911 engine - teardown 2











ok, getting deeper in to the engine...hmmm, what can i say, looks bad, looks really bad. somekind of grime inside, but the biggest so far is that one cylinder is totally gone, really deep scratches, in the piston and in the cylinder, the others are still on their place.
I would be happy if the shortblock would turn nicely (now) but no, the seize-problem is still deeper ( wrong bearing etc...) i dont know what has been in aarnio racings head, when putting this engine in "shape" :-(

next i will take the block totally apart to see the "big one"

enjoy the picks. :-( at least ...i dont...

porsche 911 engine - teardown 1






ok, i had to start to take a peek, what went wrong with mister aarnio´s engine re-build. (it took 4 years to get it back)
First, i havent seen any other engine with so many nuts, washers etc in the intake ports, plus so much crap...huh.
i took off 3 heads and discovered lots of ugly looking foam in one cylinder, and some sand/sugar looking chrystals in one cylinder, and whats pretty strange, there was also missing exhaust studs...wtf? ...and the main reason is still unclear, why the engine is freezed. :-)
