You have a PM.

I've owned a TR-3, two E Jags, and a Lotus and I've come to the conclusion that you have to like English sports an awfully lot to put up with them. Here's a few reasons why. The TR was an absolute joy for a 16 year old boy to drive around in. On the other hand, the plug-in side curtains...

For anyone interested in the engineering aspects, this site has a lot of design and application information for centrifugal pumps, piping, and heat exchangers, some interesting off-site links, and several calculators. But I haven't found a formula for the max impeller tip velocity prior to...

Can someone explain the difference between the stock Ford water pumps, the terminology they use, i.e "shortie" etc., which pumps work with which blocks, and the rpm that the impellers begin cavitation? I had thought that the Ford 289/302 engines used the same water pump until I got mine out...

On the subject of springs, I've often heard that valve springs should not be left compressed when an engine is stored because they will weaken with age if they are. I don't understand how that happens unless the steel is past the yield point, but if it's correct, does it apply to preloaded coil...

Rob- Can you rotate your fittings coming out of the sump between 90 and 180 degrees and bring your hose up along the left side? If so, a possible routing might be to run your hose up to the top, through a 180* bend down into the valve and out of the valve into a male by male elbow screwed...

My God, forget the moron with a fire extinguisher that looks like it came from under a sink in the restroom, those two clowns in the "fire truck" make Buster Keaton and the Keystone Cops look masterful. #2 wasn't even sure how to unroll the garden hose. I realize these guys aren't military...

Say what you may about Margaret Thatcher, at least she had this much right: "The problem with socialism is that eventually you run out of other people's money."

Nick- After reading your reply I researched the subject a bit more thoroughly last night and this is part of what I found out. Halon production was restricted by the Vienna Convention for the Protection of the Ozone Layer (the 1985 Montreal Protocol) because of environmental...

Some of the large turbine-driven natural gas compressors I worked around in the '70's were protected by nylon tubing pressurized with Halon gas. In the event of a fire, the nylon would melt releasing the halon at the point of combustion. The theory was that this would gain time to mount an...

I offered to loan James my ZF oil pump to take some measurements, but when I went to remove it I discovered that after sitting untouched for 8 years it had seized in the transaxle. Being the thoughtful craftsman I am, I gave it a careful whack with a lead hammer and winced as it popped out...

Good call! I think it's one of those sixties cars that just look right.

Francis- This is a bit late, but if you're still looking for a Smiths cable, these folks can help you out: Nisonger Instruments :: the exclusive Smiths U.S. Warranty & Service Center since 1949

As to books, I have Tune to Win by Carrol Smith, and it's a good introduction to tire, brake and suspension setup and dynamics. Not too technical but thorough and understandable. About $20 at Amazon.

Thanks guys- but I'm obviously missing something. I thought the two internal springs had the same action as an external one--to release the throwout bearing from the clutch fingers, allowing the plate(s) to engage. Aren't two internal springs and the spring-back of the clutch itself redundancy...

Can someone tell me if the external return spring, seen in some photos between the clutch actuation arm and the bellhousing near the slave cylinder, is necessary if the transaxle is the type with two fairly robust return spring coils on the center of the actuation arm shaft, on each side of the...

You might want to consider using the same small block Ford and ZF5 speed setup that was used in the Mark I GT40 and the Pantera. However, even with wide wheels, the Europa's aerodynamics won't generate the downforce necessary to keep the car manageable at the speeds 4lbs/HP are capable of...
