    I am posting this just to add to the 355 forum. I have spent the last week striping my spare engine down to the block. The 87K miles engine had a problem of mixing water in with the oil. I replaced the engine with one I bought second hand just to get the car back on the road.
    Anyway I have now located what the cause of the problem was, it was perished cylinder liner seal.
    So to the reason for this post. Just to say how surprised I was to how relatively easy the 355 engine was to strip down to its basic components. I made the head bolt special tool instead of buying the £500 ferrari unit. I am more used to rebuilding Aston Martin engines, which can be a PITA to strip.
    Also what I found very surprising was how good a condition the components of the engine are.
    The engine liners were in particular good condition. That hardening treatment works wonders, also the crank shaft was in great shape with no scores or damage. The shells showed a little wear, but that's to be expected for a 17 year old car with 87k miles. Although the engine always ran perfect in the 10 years of my ownership.
    Being that this is a high mileage engine now down to its components. If anyone wants a specific picture of any part of the engine, please let me know and I will post it. I have taken lots of photos of the strip. There may be some curious soles out there.
    I have ordered many rebuild parts for the engine including new shells, piston rings ,gaskets, stem seals ect (Eurospares). So will be rebuilding the engine over the winter period. The cylinder heads have already been stripped, dipped and a freshly machined face.

    Very cool.

    I'd love to see a pic of the perished seal and where it sits.

    Something else for me to add to my 'to do' list...

    Thanks, Bob.

    Here's one curious mind. Post up the pics of the teardown. Especially of the failed part/s.

    #2,4,6, and 8 with the crank removed I understand. Also the failed seal and liners, I understand.
    But I don't understand as you are a consultant why #1,3,5,7, crank in. Because there is nothing to see abnormal to any other engine. Or is there?
    The head tool was made using a brace bar with a socket welded to the top and the end of a snap on 15mm spanner welded to the end of the brace bar with a steel reinforcement ring around the weld to help deal with the torque. Most of the nuts were removed using another 15 mm snapon with a breaker bar. The head tool was made more for the replacement of the head nuts when the time arose so I could get the torque setting correct. Although I did use the tool for a couple of the nuts to see how it faired.

    Cool Project!

    I'm just putting my engine back together myself.

    One thing that really surprised me was the casting quality of the heads. I expected way more from Ferrari. Looking at your heads, your combustion chambers have the same cavities and pits that mine did. I am very fluent with BMW and Porsche engines and you would never see such casting flaws in their factory heads.

    They look pretty good to me, actually they looked polish although I see a small amount of porosity. Having work for a GM engine plant, I can tell you GM's don't look that good ;-)
