Possible Cracked Manifold?

[joelpsmith 1]

I replaced the dipstick tube on my car, obviously having to remove the exhaust manifold, I refitted it with the same gaskets and it developed a slight ticking noise. I assumed it was the old gaskets that were the cause and have since replaced them with brand new peugeot items. Unfortunatly the ticking got a lot worse immediately after fitting the new gaskets.

 

I have had a look for cracks in the manifold but can't see anything, are they always visible? or is it possible to have a crack that can't be seen?

Had a look from underneath too?

Yep, been under there with a torch, had a good look from every angle and can't see anything out of the ordinary.

try feeling it.

or get a thin bit of paper and see if it gets blown at any point by the gasses escaping.

 

with the engine on obviously

I expect the face needs machining, most have eaten away at the edges now and a re-face works wonders

Thanks Miles, I suspected this could be a problem, i'll give it a go.
