What is "special" about a V12 rebuild?

Or 250 TR recreations

 

Well I must say that you JCR continue to spew forth crap that is valuable to no one and spread insults and misinformation. Did you ever wonder why no one really responds to your flottsom.
You really don't know much about Clevite, do you. They have been around for more than fifty years, so go back into your little hole and plan your next attack because thats all you are capable of doing and will continue doing. No one is interested in hearing any more of your negative misinformation. No one really has the capability of understanding your superior knowledge anyway and your vast technical apptitude is far beyond any on these pages. It is far beyond anyone to understand how you can attack so vigorously anyone who might have even a slight difference in opinion than your own, your opinion believe it or not, is not the only opinion of importance. These pages are about what you are not, a friendly exchange of information not a manic expression of inferior ego. You definitely have major communication problems and are in need of assistance.
You are very capable of sourcing and googling much and now is the time to google much needed info to help yourself. It seems that you have great difficulty in not pissing people off or rather take great pleasure in it. Now don't act introspectively, please, launch an all out exspected attack and show all the venom you are known for and capable of.

 

NUTS! Get it, NUTS! I come to this forum to learn technical aspects of Automotive mechanics by either sharing my expertise or gleaning the expertise of others. If you disagree on an aspect of automotive engineering or mechanics, please so state and give reasons why. Attacking someone and calling juvenile names WILL NOT SOLVE THE PROBLEM! The purpose of the forum is to SOLVE THE PROBLEM. Don't you guys understand that? Nobody here is your enemy. This is so tiresome. I'm sorry.

 

Why do you think no one, and I mean no one who has so much as had a valve cover off one of those motors is responding. Too many internet warriors want a fight.

**** em.

 

Exactly. You might have misunderstood. I meant that gentlemen like you have an experienced opinion on the resolve of a particular technical issue. A disagreement can be discussed, clarified, and resolved in a professional manner. I have seen you do this many, many times. Those of us without that expertise can benefit and learn. I, frankly, have learned a lot from you. What I don't like are the "internet warriors" who cloud the issue. As you allude. this is not a place for a fight. It is a place of learning. With best regards for your continuing help!

 

Thank you for your comments but my continuing help is being drastically curtailed and will probably dwindle to zero as I see this place becoming a sewer due to the apathy to do anything about what has already transpired in this thread. It has become a great study in how a few can drag down an entire society into anarchy. There are a number here who simply cannot conduct themselves in a civilized manner and sadly they drag many of us down to their level, me included.

Life is too short.

 

I couldn't agree more.

The personal attacks do take the fun out of it.

 

JCR gets a three day ban for personal attacks (and not just for this thread, but for a pattern of behaviour). Further attacks will generate a longer ban. Unfortunately I don't have the ability to delete posts in the thread, but I hit the ! button to alert the tech mods to the problem and hopefully they will clean it.

 

Whoopee! perhaps a good thing.

 

I am almost speechless. Thank you, Tillman, and everyone else involved. Rifledriver, please continue to offer your sage advice, its much more welcomed than you probably realise. While we all like to blow our own horn a bit while offering our knowledge or advice, none of us like to be constantly harrased and discounted. Its one thing to ignore people who offer this stuff, its quite another to get mean and nasty about it when you dont agree. I havnt met a person yet who knows everything, but there sure seem to be a lot of people around who think they do. I also think we all need to take a more pro-active role in allerting moderators, by figuring out how this ! button works, to bring attention to these problems before they go this far.

Now back to our regularly scheduled program.

1 Cold winding. Wire up to 0.75 in (18 mm) in diameter can be coiled at room temperature using one of two basic techniques. One consists of winding the wire around a shaft called an arbor or mandrel. This may be done on a dedicated spring-winding machine, a lathe, an electric hand drill with the mandrel secured in the chuck, or a winding machine operated by hand cranking. A guiding mechanism, such as the lead screw on a lathe, must be used to align the wire into the desired pitch (distance between successive coils) as it wraps around the mandrel.

 

How right you are.

I don't think that this was the method being described in that humorous post.

 

I have done these since 1979, I call all the top parts suppliers and get a quote on all new parts from all the guys, Ive been very lucky to have only done 330GTC, and always found a standard crank. Sometimes you have to wait for parts to come available as they are made in lots and when fresh pieces comes out ,stock up, these are old cars and they are breaking stuff now{stub axles] that never gave trouble generally in the old days, so go easy on Her and get all the parts together before surgery, if you could. IMHO the machine shop is the key, I use an oil field major [as in giant] equipment machine shop as they are all dragsters , and they got really great machine tools.These guys build a lot of engines,and most dont last long compared to a GT redcar. I like local drag race machine shops with nice equipment and a couple of employees.$12 to $20,000 will pay for parts and MW and you do most of it, get a pro to com e over and guide the project and pay him $5000 to assemble it, and $1000 to guide you thru the install and tune it There is nothing to assembling V12s thats different from any other racing automotive engine untill you deal with the timing case and all that timing. The valve timing is crucial to get that V12 rip.

 

+1 Zingara, and Brian you know how I feel about your help and knowledge. regards, Vern

 

My experience with our v12 250 engine has been about the same as the others posted here. I have built my share of Chevy, Alfa, and Nissan/Datsun, Sunbeam, and Fiat engines but when the head gasket on my 250 blew and coolant was running out the exhaust pipe, I was very badly prepared for the cost of parts to replace it........and this was about 1980 (over 25 years ago). I had to commision a machinist to frabricate the special tools to lift the head off the block. The original gasket was composed of 13 individual parts, two rings around each cylinder and a peripheral gasket. I had no idea this was so until my friend and I took it apart. Holy Hannah, what the heck is this we asked each other! Anyway, the parts desk at FAF in Atlanta was very helpful, they had a pair of modern single-piece head gaskets on the shelf and shipped them to me, but then the tricky part of re-assembly was getting the o-ring between the front of the cylinder head and the timing chain cover to seat correctly. We were hoping to hear that reassuring klunk as the head dropped onto the block, but had to make repeated tries to keep the o-ring out of the way. Gees, we spent hours and hours trying all kinds of metal shims (ultimately a Coors beer can) to get that damned o-ring in place. I can easily multiple the time it took us to R&R that gasket to estimate the time to rebuild an entire engine........ and at today's prices! Holy Hannah

The other lesson learned here was to pass on the temptation to drag race a fuelie 1957 Corvette. It is not worth it!
