Dude, you called your cat Steve? (IMG:style_emoticons/default/WTF.gif)

This is how the bus guys do taco plates

http://www.germansupply.com/home/customer/...297&page=19

$52 is pretty pricey, but a real taco plate, of which I have seen all of 2 for sale in the last 8 years I've been looking off and on was going for $85.

I made my own out of billet aluminum, on a lathe, but I might be tempted, coming up to replicate what they've got going on there. The welds don't have to seal, since the nut is on the inside, and the seal is on the outside. You just want to avoid burning through or putting too much heat into it as not to warp it, it seems, and then clearancing the nut... or you could buy one from german supply.

mmmm... taco plate (IMG:style_emoticons/default/mcmark.gif)

"Who is using leaded gas?"

I have owned 3 VWs and 3 914s and have always run leaded gas as BOTH of my VW mechanics said to run leaded.

I also am involved in Vintage racing, so almost everyone at the track runs leaded gas ( a LOT of the cars are pre-67 ).

I am not saying its a bad idea for the motors, I am just wondering if you realize that in addition to being highly toxic, it has been illegal for use in road going vehicles in the US for the last 15 years. You are looking at up to a $10,000 fine if caught using it on the street.

You only use this at the track right?

Moot point.

It's clear that while leaded fuel does exist, its clearly far far far away from normal, everyday use for 99.99% of your typical street drivers. It's availability is just a technicality if you think about it. The fact is that pretty much every car for quite a long time now has an O2 sensor and was designed to run on unleaded fuel. In fact, all of the information I found on the subject shows that it is leaded fuel (not unleaded fuel) that can cause O2 sensor damage, along with damage to your catalytic converter and the nervous systems of your children.

While it is possible to obtain lead-laden race or aircraft fuel, and while I'm sure that would be fun to drive in any of my vehicles, realistically I'm never going to do it. So my O2 sensors are safe. My stated design goal is to build a driver, not a racer.

Oxygen sensors are also safe to use with high octane E85 [FORESHADOWING], which is available just down the street.

I foresee a day sometime in the next few years where it could make a lot of sense to have a instantly-tunable EFI system with spark and timing control that would run E85. It would be nice to have an EFI system that could adapt to modern fuel changes.

Stainless steel fuel lines? Ordered.

What's wrong with naming my cat Steve? I named him after Steve Reeves from those ridiculous 1960s Hercules movies because he has huge, furry ... attributes. The name suits him well.

You have been wasting your money.
All VW's have "unleaded seats", in fact one VW bug head retailer used to claim in HotVW ad's that their heads had "unleaded seats" which was nothing but a con job as they came that way from the factory. VW and Porsche use steel seats and bronze guides.
The only cars that had problems with seat erosion were older cars that ran cast iron heads (and to a lesser extent cast iron guides) where the seat was cast right into the head.

Cast iron seats need leaded, steel seats have no problem with unleaded fuels.

AV gas uses a totally different octane rating system and can be detrimental to an engine meant to run automotive gas. In fact the "trick" conversion for aircraft owners is to convert their engines to run on regular gas.

Leaded does foul O2 sensors, to clean them you can hook them up and run them in a car using unleaded to burn away the lead deposits.

My friend pulls a couple of dual bigblock tractors and uses av gas in all of his normal show john deers. It never goes bad and he only puts a small amount in each one and they always start right up in his toy shed when he plays with them or loads them to go to shows. He gets it in 55 gallon barrels and it stays good indefinately he says. My antique tractor friends use regular unleaded in all their stuff and my friend that uses about 15 antique tractors on his farm daily uses unleaded in all of them. He will not live long enough to wear the seats and guides out. If preventative measures were needed on a carbed motor without the o2 sensor a upperlube could be added but he builds his own tractor motors and doesn't have any problems, he's been doing this every since the fuel changed, you just can't let them set a long time or the gas will varnish and gumup the fuel system badly. I have ruined two fiero fuel pumps letting them sit for too long with fuel in the tank.
