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...

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. In the past I have not used either just some aviation sealer (same as I use for the case). But should I be using a gasket, if so metal or paper? I am concerned a...

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

I need to remove the bearing housing form my axle tube, does anyone have any tips on how difficult this is? 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 ...

I recently had a case line bored and thrust cut. The shop that did the work sold me the main bearings (steel backed, mfg unknown). The bearings have the 2nd main (steel backed) grooved on the outside diameter. CIP sells main beraings that are grooved outside and others (KS) that are grooved on the i...

I have 2 questions.......... I am trying to understand piston to cylinder wall clearence. I have been told that a vee should have 0.004" to 0.005" clearence. Is this the difference between the inside diameter of the cylinder and the outside diameter of the piston, or is it 1/2 this differe...

Thanks very much this is the information I was looking for, very helpful. Now............ how can I get 150 mph out of my vee hummm.........................

Appreciate this,
cheers, don

I have a question............2 indentical vees except one has external ducts to the heads / cylinders and oil cooler. The other uses the VW fan and a gutted generator (only function is a bearing holder for fan). The first vee will have a larger forntal area by the same cross sectional area of the VW...

Guys: Thanks for the suggestions, the seam does not appear to leak sitting in the garage with cold oil, but only when it has been run. I will wipe it clean retorque the case bolts, start it up and watch for the leak. One other question if I did use thread will this be a onetime thing (ie will it lea...

after 6 race weekends the case is leaking along the bottom seam. I am curious as to what is reccomended for sealing the two halves. I use Permatex Aviation (brown stuff) gasket sealer. Also I stumbled accross a VW aircraft website where they used a strip of Teflon dental floss between the case halve...

Just finished my first race of the season. Saturday sessions were fine but on Sunday during the last session the transmission started copming out of 3rd and 4th gear on acceleration. I do not have any history on the tranny. First sign of an issue was hard to shift into 3rd from standing still at pre...

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)?

thanks, don

ok.............have seen this thred before but did not reply. just can't keep quiet. I had the same question this spring, after many discussions with "the guys at work", info on youtube and internet; I deccided to paint my FV myself with Tremclad rust paint (Rustoleum). Worked out just fin...

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...

The Simpson website does not specify what certifications the Safety Solutions Hybrid style restraint system has. Does anyone know if they are SFI and/or FIA certified?

don

ok...........lots of useful and not so useful info on the web for head and neck restraing systems (and I am aware that "HANS" is patented, copy righted etc). I am looking for a "budget minded" system for an FV for club racing, and one that is the "least bulkiest". There...

Trying to wire up a generator dash warning light. One lead from dash light goes to the voltage regulator (terminal 61) and the other goes to? From what I can gather from various wiring diagrams the other lead from the warning light goes to the 12volt + "on" side of the ignition switch. Can...

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...

Hi: I am finishing rebuilding a vintage vee that has 4 seperate exhaust pipes rather than a collector. There is a noise restriction where I race. A vee with the usual 4 into 1 collector and megaphone is under the limit and is ok. Does anyone know if 4 seperate pipes would be signifcantly louder (or ...

I am rebuilding a "one off" vintage fv, but will post this question here as it applies to any fv. Is it reccomended to put fuses in the wiring circuits (and where would they go) or is it a non issue. Fuses are usually used for heavy current draw circiuts like light horns etc. I am inclined...

I have a fuel cell question.........(I appreciate that I should be asking the SCCA, however I will ask it here first) SCCA section 9.3.27 states...."All safety fuel cells shall be.....certified ....FIA FT-3.....All safety fuel cells shall consist of a foam filled bladder enclosed in a metal con...

thanks all for your input, appreciated,
cheers, don

I recently rebuilt my engine. The new main bearings that I bought do not have a steel backed split bearing. Suppose it is a little late for the question (the engine is installedand broken in!)..........
Are the non steel backed bearings ok?

thanks, don

Tried to upload pic, but can not form some reason, receive message "Could not upload attachment to./files/595............). Can I email it to someone to load? The pic shows the car is off the floor on a dolly and the rear is at full droop with the cables tight and each spring is compressed abou...

sometime a little knowledge is................. For an intial rear camber set up (6 deg neg on the ground with driver, and max 1 deg neg off ground at full droop per SR Racing book). My car has zero roll with outside coil over shocks and droop cables on each axle, and an adjustable cross rod between...
