Le Français

Toujours, je suis désolé pour mes amis( et amies) français(es), mais il est difficile pour moi d'écire en français. Peut-être un jour...

Rocker Shaft Issues

Many times working on Fulvias, I have found problems with the bolts that secure the camshaft bearing caps/rocker shaft supports. Often this is because stupid individuals have mixed up the bolts and not noticed that one of the longer bolts is slightly shorter... Also I suspect that the very hard aluminium alloy used by Lancia for the Fulvia engine might be prone to crystallisation/ cracking after years of cyclical stress. either way the nasty Helicoils® tend to give way. They should be replaced with Timeserts®

Edit: After re-reading this, I should add that another cause of Helicoil(r) problems is over-tightening of the bolts. Every overhead-camshaft engine that I have worked on has not required extreme tightening torque on these bolts and of course the Fulvia is no exception. the correct figure is 15.9ft/lbf, or 2.2Mkgf, or for the younger ones, 21.6NM

Anyway the following can happen (though I've not heard of it happening in a Fulvia) My first Fulvia that I bought in 1982 had a persistent tappet noise that no amount of adjustment would cure. It was due to a Helicoil that had let go...

A bientôt

Music and Radio Blog Club

Radio Blog Club, a good friend for a while appears to be in some legislative difficulty...

However, in tribute to its brave effort, I shall leave the existing track on this page (which amazingly still works)

Sadly my Playlist no longer works (hence its removal) thanks to the absurd "Hadopi" legislation in France. Apologies to all.
