Anssi Posted August 20, 2020 Share Posted August 20, 2020 oliko joku konsti jolla tunnistaa onko venttiili natriumtäytteinen? nelostyypin pakoventtiileistä siis kyse Quote Link to comment
tolvana Posted August 20, 2020 Share Posted August 20, 2020 Painosta ne ainakin maseratissa erottaa ja uusittavahan nuo venttiilit on jokatapauksessa n.100000km välein jos vw n ohjeita uskoo. Eli pakovenat aina uusiksi ohjurirempan yhteydessä. Quote Link to comment
Anssi Posted August 20, 2020 Author Share Posted August 20, 2020 Juu nää on NOS kannet + venttiilit (ajettu 10tkm asennuksen jälkeen). Kannet ovat nyt irti mutta venttiilit paikallaan, näkeekö jotenkin muuten kuin painosta onko täyte vai ei? Quote Link to comment
arvuuttaja Posted August 20, 2020 Share Posted August 20, 2020 Yhet tippu joskus pajan pöydältä lattialle ja tuloksena molemmat poikki.. Quote Link to comment
spege Posted August 20, 2020 Share Posted August 20, 2020 En enää muista nelkun normiventtiilin varren paksuutta mutta natriumit on 9mm varrella. Myös typ 1 pakujen koneissa, jos sellaiset on. Quote Link to comment
KimmoH Posted August 20, 2020 Share Posted August 20, 2020 Ratwell sanoo seuraavasti "The designers came up with additional cooling solutions such as using sodium filled valves. The sodium liquifies at operating temperatures and the liquid is flung from the head to the tip inside the valve stem by the action of the valve to help to cool it. Some of the 1.8L Type 4 VW engines used sodium valves and you can identify them by the dimple in the center of the head andthe 0.008" valve adjustment specification for this model instead of the normal 0.006" clearance." he designers came up with additional cooling solutions such as using sodium filled valves.

arvuuttaja Posted August 24, 2020 Share Posted August 24, 2020 Palotilan mallista päätellen, taitaa kyseessä olla 1.8 koneen kansi 41/34 venttiilein.. Quote Link to comment
