Hello I'm about to change the hydraulic tappets on my 1990 2.6 auto but would like also to change the bottom washers between the lifter and the top of the valve. The problem is that the Russian parts site indicates two measures: 3 mm and 3.5 mm. Which ones should i want? Being half a millimetre difference that would reflect in the travel action of the hydro lifter. Would there be a negative effect in case i would chose one or the other thickness? Besides, at the MB dealer, they only have the 3.5mm. Could the 3 mm be for a kind of first version of the m103 engine? cheers |

It might improve performance a tad as the valves will open by an extra 0.5 mm if yours were the 3.0 type - extra fuel compsumption too. |

So, from a fitting point of view, the 3mm ones wouldn't be a problem? I'm not looking for improving performance and even less more fuel consumption. |

If you can only get the 3.5 mm ones then it won't concern you whether the 3.0 mm are a problem to fit, or have I missed something? @daliscar - sounds like a Wallace invention: The Grommit hydraulic bottom washer. Edited by Gerry Lloyd, Sun Apr 29, 2012 11:17 pm.

Decided that will leave the old ones there as they hardly get worn anyway, so.... |

...that's true the camshaft lobes and inlet rocker lobes were vey worn on my 100 000+ mileage 2.0 litre, so 0.5 mm on the bottom washers would be insignificant. |
