I wrote VW off a long time ago. I bought a new 1600TL in 1966, big mistake. Seems they had a problen cooling #3 cylinder because the crank mounted fan twisted the air away from that corner. They could have changed the shrouding to use the air under the engine which would be twisting up around that corner of the engine, but they couldn't be bothered. Instead, they retarded the #3 lobe in the distributer cam to make that cylinder run cooler than the other 3. They didn't seem to care that this set up a rotary vibration that unscrewed all the left side of the engine. The left head had to be retorqued at least once a month and twice a week the idle mixture screws had to be run in on the left carb and out on the right. The floor pan was so thin, the brake pedal stop tore out at around 30K miles even though I'm not in the habit of dropping the brake pedal. The last straw was when the head fell off one of their wonderful innovative spin welded valves and punched a hole in the piston. I gave the POS to my brother-in-law. He and some friends rebuilt the engine and it lasted a whole 23 miles.
