    The photo shows the intake manifold inlet of a 308 (carbureted version). There seems to be some reddish, crystal-like substance attached. Do you know what this might be?

    Have you seen my recent post "Unusual deposits on my inlet manifold". Sounds similar. I have stripped, cleaned, resurfaced, smooth, and renistalled my manifolds and so far so good. Just fighting the oil leaks on my cam shaft seals with my newly delivered bucket of Loctite 518 and I should be sorted.
