I had a 93 Honda Del Sol with over 300k and never touched a wrench to it. They really are tough little cars. The interchangeability among the model line is as good or better than VW, you can mix and match engines easily. |

I've done over 300K on numerous Honda's, checked the valves now and then, never ever had to adjust anything. But it's apples vs: oranges comparing it to a flat air cooled engine made from economy materials, water cooled rocker on cam is completely different than pushrods and a bunch of things that expand with heat they are attached to. _________________ Rust NEVER sleeps and stock never goes out of style.

If it's stock adjust them at VWs recommended service interval of 6000 miles. If modified check as often as you feel necessary for your application. VW never said adjustment was needed every 3000 miles. _________________ Pres. Rivercity VW Club www.rcvwclub.org

What does Chevy suggest for milage intervals
To adjust solid lifters on their small and big blocks? Bet it's close to VW. _________________ Pres. Rivercity VW Club www.rcvwclub.org

The 36 hp engine requires valve adjustment that often because the lifters have a flat side on them that runs against a steel block in the case and they do not turn like the later lifters. As far as I know they were the only engines that require the 3K interval.
Remember them? The push rod was pressed into the lifter and you could pull them out through the heads with the rocker shafts off and change them out. Everyone that put major miles on a 36 hp engine had a bucket full of worn out lifters with their pushrods in the corner of the garage. _________________ We had the stone age, the bronze age, the industrial age and now we are in the age of mass deception and mind control for corporate profit.

Yes they did go back to page one to see the manual references. They (VW) made the 6k change around 1971 and in a service bulletin established .006 as the setting for all models superseding early information. They did this to avoid all the confusion which is still present it seems. If you don’t run hot you’ll most likely never experience a problem in stock form. |

Not sure you're serious...
In any case, Honda called for adjustment if necessary every 30k miles. The problem isn't noisy valve trains, but recessed seats. The valves don't close completely. No excessive noise, but the exhaust valves will burn. They need to close completely to cool.
Later Hondas still called for adjustment every 110k miles.
YMMV |
I'm serious. When valves wear, the gap widens & you hear that click & yes, the seat deepens & the valves groove but you hear that. If the valve did not completely close, you would lose compression. |

it's a cheep car what do you expect? but if it's built right with the right parts preped right and the right oils it can go much much farther. but if you just build disposable vw engines like most do..adjust away. |

On an air cooled VW normal wear opens the gaps with time - period! If an exhaust starts to tighten up... you are in trouble! Take the head off and replace the exhaust valves NOW! The only way they will tighten up is from the valve stem stretching under the head because it has over heated and is weak. If you just adjust it and go it will not be very long and you will be buying a head, piston and possibly other internal parts.
Other makes of engines may wear differently but that discussion is irrelevant here. _________________ We had the stone age, the bronze age, the industrial age and now we are in the age of mass deception and mind control for corporate profit. (The mass media age) |

Anyone that has daily driven an air cooled VW past the venerable 36 hp knows that 3000 mile interval for valve adjustment is excessive. Once the initial break in period is done they just don't change that much. Touching them up every 3rd or 4th oil change is more realistic in my experience. With the lack of quality of the modern valve cover gaskets taking them on and off every 3000 miles will have you chasing leaks perpetually! _________________ We had the stone age, the bronze age, the industrial age and now we are in the age of mass deception and mind control for corporate profit.

Multi staging was a Russian design from 1946, but once you really decide there is more to the world than Olive Garden, you find thought of this in 14th century.
I’ve scoured curricula and found Engineering, but nothing called “ American Engineering”
Does that include Canada ? _________________ .ssS! |
