    Ok, the ice has melted and I pushed my 64 Dart GT halfway out of the garage and I have the charger attached to the battery. Now, after reading Doug Dutra's new book, I discovered an oil leak where the alternator mounts attach to the engine. Therefore, my mechanic whom installed the remanufactured engine also did not know that the bolts need some type of sealant to keep that area from leaking oil. Is teflon tape appropriate for this job? And, do I need to completely remove the alternator to do this?

    It may be easier to reach the bolts if you take the alternator off.

    I wouldn't use Teflon tape. That's for tapered pipe threads. You can use the thread sealant referred to above, or what I use is red high temp RTV. Works very well. But they do need something.

      Doesn't it say what to use in the book? I would go with RRR silicone, also permatex thread sealer that was also suggested.

      No the new Dutra book, page 117, does not indicate what sealer to use. That is why I asked the question.

        I have used both liquid Teflon and silicon sealer. It doesn't really matter what kind of sealer you use there. It isn't really a critical place, just somewhere prone to leaking.

        I made the repair this morning and I was able to perform the task without removing the alternator. It was so easy even a caveman can do it.
