He lied to me !!!
He told me the car was prepared for lead free petrol... sales talk !!!!
Now, only one tank of lead free later, the valves won't close as the seats have receeded.
Now instead of 60PS I have 6 and it makes very rude noises.
sympathy - or stories where you were stupider than me - appreciated. <img src="graemlins/c.gif" border="0" alt="[ouch]" />

Hello
Did you fixed it into your salescontract or have a whitnes ? If you are in germany and bought from a dealer you are in a strong position.
Now most 356 had hardened valve seats from the factory ( Porsche isn´t sure about the early years and how the rebuilders handled that ) so thats maybe not the cause from your problem.

Yes I checked the books and saw what they said about hardened valve seats but...
what else can cause the seats to receed ?
I checked the valve clearances and on most cylinders there was none !!!! but the car had been running fine for a couple of weeks.
on adjusting the valve clearences the car is better but not perfect.
What other possibility is there ????
(Please tell me something cheaper than new cylinder heads)

Dear Irishdriver,
As you asked in your first post about stories and stupidity. Nope yours is the best one yet (just kidding).
Porsches that used Super leaded fuels, normally run perfectly okay on 98 Octane Unleaded "Super Plus". If you used 95 Octane then you would certainly be in some bother. This would also reduce your case against somebody saying use "unleaded fuel" because they should go on 98.
Of course have you considered it had nothing to do with the fuel.
I would be interested in which octane you did use. Is this 356 your C4 slalom replacement. I thought you were a 914 restoration person or are you going to become the Seinfeld of Germany,
Ciao,
Adrian

<img src="graemlins/roflmao.gif" border="0" alt="[hiha]" /> Very funny (who the hell is seinfeld?)
Actually I was overreacting. I've re-adjusted the valves, read all the 356 books, and things seem to be OK. The 356s' were sold with relatively hard valve seats so they should be OK.
I think I just had a car that had poorly adjusted valves that was not driven enough.
Anyway now I'm down to a flat spot between 2000 and 3000 rpm which could be running too lean or the spark is a little early for the party.
No, the C4 will continue to do slaloms until I can afford a 993 C4. The 356 fills a gap between now and when the 914/6 eventually gets restored. (just don't ask me to promise to sell it when the 914 is ready).
Keep the faith
