I have just bought a 1979 2 liter kombi. The owner had fitted new Brazillian heads to the motor. He tells me that I must put in a vave protector like Flahlube. Question do I? I own two 1972 beetles that have always run straight unleaded for the last 8 years no problems.
Also does the 1979 kombi come with two speed wipers?
There is a gadget don't know what it is called that you can place in the fuel line that adds lead for years anybody know what it is and how much and where do ya get it ?

Use flashlube. It can't hurt. It actually helps with carbon deposits from fuel too.
The main reason for using flashlube or similar is to slow/stop valve seat regression. VW valve seats are hard, but not always hard enough. I don't think it does much for protecting valve guides though.

I remember those lead replacement thingies. I never had too much faith in them. They may be good. i don't know. I pretty much pigeonholed them with hyclone and electric superchargers.

There was a big thread about fuel additives recently on the forums. Might be worth having a search.

do a search on fuel adds ,its been flogged to death but generally no adds just unleaded is fine and kombis have 2 speed wipers

Um, I have two speed wipers, but neither of these speeds is intermittent. It's still better than on the datto though; there, the wiper control is on the dash, not the steering column!

Also, it was my impression that Premium Unleaded (higher octane) was the preferred fuel. Less pinging -> longer engine life. I use Premium, no additive, in my '74 carbied 1800. All good so far.

If I can get 98 ron, in she goes. Nothing less if I can help it.

C .R 7:1 std engine calls for min 91 ron ,exactly what our std unleaded is, if it pings at that retard it to std settings.

I have one of those in-line things. I bought it years ago at CustomOff Road at Stafford, but now Brad has taken over I don't know if they still sell them. I think I saw some at Mick Motors though. From memory they cost around $150?

i use lead replacer. Got hardened valve seats when we rebuilt but it cant hurt to use it... not really keen to spend another 3 months trying to find a set of 2L heads again.

save heaps of bucks-- go to the hardware store nearest you and buy a stick of 60/40 tin lead solder tie cut it up and shove it in your tank ,,same result cost $3

You could also just add 10ml of oil to your tank, this also works. Make certainit is a mineral oil.

This works well in unleaded vehicles too.

It makes the car go better as well.
