Newly Rebuilt 1966 Engine Oil Leak
Hi. I recently had an original F block '66 engine completely rebuilt
by Archway Imports here in St. Louis. Supposedly they do very good work. The engine runs great, near as I can tell, and has been bored out to 1600 for more power. Fuel consumption seems rather high, but I don't really know what to expect in that regard (I might post on that topic later). But I'm getting some oil leaking out the bottom casing, not really sure where it's coming from though. Not gushing, just a light coating and slight drips on the undercasing. The rebuild has about 350 miles on it so far, mostly city driving, but some highway miles. Archway made valve adjustments and checked the timing at 250 miles, but I hadn't noticed the oil leaking at that point. Should I be concerned? Roy |

To do the job right more than one type sealer is needed(according to those in the know). Loctite 510 is a flange sealant which is often recommended, also by producers of aircooled engines today(Piaggio). I have personally used it with success on several engines, very easy to apply. Permatex is another quality product. Just make sure you understand that both these brands have a wide range of products, and you need to pick the correct one for your application. The biggest problem with rebuilders of aircooled engines today is the fact that they simply ignore what the factory ones specified for sealants, and simply use what is available. The price of Loctite/Permatex products are also significantly higher than your average FLAPS universal sealant. Best of luck. P.J.Berg. |
