oil presure threads
I have just put together an engine with a dual relief case. The fitting for the oil pressure guage (1/8 npt) leaks at the case threads. The threads in the case do not look damaged, and I don't see any cracks. Before i chase the threads does anyone know if they are 1/8-27 npt (North America) or 1/8-2...

Flywheel to crank gaskets
I am rebuilidng an engine for next season, and a question came to mind regarding the paper or metal gasket between the flywheel and crank.

Re: Axle Tube work
Jim, thank you for the info on removing the hub, I will give it a try.
As to why.......I have a transmission with long axle housings and the bell shaped retainer for these axles uses an o ring so I want to use this style on my short axle tubes as I am always fighting small oil leaks.
thanks, don

The pin in the housing has 2 small flats machined on one end and three punch marks on the other. I assume the pin is tapered, which end is pushed out; and can I pound it out or do I need to a ...

Are there any modifications required to using a stock 009 Distributor for FV racing, I have heard of people removing one counter weight spring. Is this a good idea, or can the distributor be used in its stock configuration (given that the timing is set correctly)?

I am interested in opinions / reccomendations for HANS, Simpson Pro Rage, or Simpson R3 Rage restraint systems for useability (fit) in a vee. Both seem comparitivly priced, so a decision would be based on fit and comfort. I appreciate vees are different, but given a representative vee cockpit with a...

Just bought some 5 oz Kevlar. The company I bought it from said it won't cut with scissors or a knife, maybe tin snips. They have special serrated scissors for $70 but for a one time project, too expensive. I thought maybe clamping it between 2 pieces of wood and use a cut off disc on an angle grind...
