    Maybe I do things wrong, but all I do, to tighten the cam sprocket, put the belt on, set your timing, tension the belt, then I have an assistant hold the crank while I torque the sprocket. Rotate the engine around a few times, check your timing etc. Never ever failed to work, nor ever had a problem. Trying to tighten that sprocket without a belt on it, or some kind of holder is indeed asking for trouble.

    Sorry about your luck. I'm sure you will fix it and have a beautiful car to drive. Enjoy!!

    Well Howie your method works if you have an assistant and if the belts can take the torque. Great to know they can. I'm not a trained mechanic so errr on my idea of caution keeping force off the belt. Your method is faster and safer since you can't make a mistake leaving a cover in a cap if there was never one in there in the first place.

    LOL!

    Chris, can you please tell me the serial number of your 599? I believe it's the only one of your Ferraris not properly documented in my database. Thank you.

    Using the match book cover method couldn't that permanently distort the caps?

    Or am I misunderstanding the technique?

    Cheers, Paul

    I like the idea of the razor blade cover material. That way I can slit my wrists will all the razor blades if I F-this up a second time! But seriously, I intend to use this method.

    I don't like the T-belt in place method though that is what I used for the 7-12 cylinder bank (which turned out fine). The problem I had on the (right hand) 1-6 cylinder bank is that I had to pull the tensioner off to rebuild it and didn't have a belt on at the time I did the final torque of the cam wheels. That was my mistake. I tried putting a clamp between the two cam wheels but it didn't hold when I hit the bolt with the impact.

    I will have the head off tomorrow. My valves, gaskets and other parts (including my new 599 Challenge rims!) are arriving this week from Europe. I plan to have the head ready for re-installation for Thanksgiving weekend.

    OK, head pulled successfully today. As expected, two bent exhaust valves on cylinder #6. Way bent! And little kiss marks on the piston (but surface level only, no indentation, just two bright crescents into the otherwise matt perimeter area).

    So, off the the machine shop to have the two exhaust valves installed and then a much more careful approach to tightening the cam wheels.

    Funny I've never screwed up a timing belt install until now. Got rushed and stuck with no help at the time. That'll learn me!

    And head gasket still looks like new but I guess I've got to throw a new $200 gasket on. Ughh!

    What a great spirit - sure your Scal will be so much closer to your hard when its up and running than a "just bought" Ferrari! Had similar experience with some of the bikes I build up from scratch when I was young(er).

    All the best from Europe,
    Stefan

    Hang in there. That is a pretty small mistake considering how much you tackled. Did not think it would take you long to remedy and everything is easier the second time around. Especially so since you did not have to pull the engine again. There is a locking tool for locking the crank, but the WSMs just show ViceGrips for holding the cams in place.

    Jason,

    While your intake is off, you may want to get the new 612 hose kit from Scuderia Rampante.

    This is a brand new kit to deal with the rubber 180 hose failure.

    Cheers,
    Shiv

    OK, I looked at your prioe forum thread on this but couldn't find any non-OEM alternatives. So, for now I've added the OEM part to my upcoming order. Thanks Shiv.

    Dave and crew at Scuderia Rampante Innovations were just putting the finishing touches on that pipe to replace the hose last time I heard. Probably worth a call.

    Looks a lot sturdier than the 180 deg bend in the rubber hose.

    Does anyone know if they are coming out with a similar kit for the 599?

    I haven't seen the 599 motor close up..but I had a very close look at the F12...there are no more rubber hoses in the valley. The new design is very clean in this regard.

    I'm sure Taz will fill us in.

    OK, parts are in! Head has been repaired and is ready for install tomorrow!

    Also, my 599 Challenge rims arrived and I've ordered my Michelin PSS tires.

    Stay tuned for updates over the next few days!

    If you ever think you are having a lot of bad "car luck", well welcome to my world...

    I put the "repaired" head in today. And then did a leak down before moving too far past just flat head install. Well, turns out my intake valves must be bad (not just my exhaust) on cylinder #6.

    So, head comes back off tomorrow and goes back to machine shop. I wish the guy would actually do his job right and check the whole head and not just the valves that had an obvious bend.

    So... another $500 investment coming and a few more days wasted...

    Ugh!

    Yeah, it must be starting to sound like I don't know what the hell I am doing...

    But... in actuality, I learning some good lessons in inspection and patience. Stupid of me to expect that the machine shop would have checked the head for vacuum, right?! I should have sprayed fluid into the ports to see if any flowed through, etc. before putting the head back on.

    Well, whatever doesn't kill you (or make you completely crazy), makes you stronger. This timing mistake has obviously cost me a lot of time and about a grand, but at the end of the day the car will be solid... by this Spring!

    So, will attempt again in two weeks.

    - Jason
