Right, managed to get the head off with the help of Turtle and a recent purchase of an angle grinder! Had to grind one of the head bolts off as the inside got all mangled even though I had bought the correct M13 RIBE tool - mine was not a tight fit though, so I will get a new one!! (See http://www.alfaowner.com/Forum/alfa-...d-removal.html
Good news is that the problem with the misfire (see http://www.alfaowner.com/Forum/alfa-...preciated.html
) is that there is a crack in one of the exhaust valves - meaning little to no compression at low revs I guess...
So, got to change this valve...
I have disassembled the head tonight, in preparation, and I just wanted some opinion on the colour of the engine internals, does it look like its running ok? I spoke to Ned from Autolusso today who said a chocolate brown colour is what it should be like, mine seems to be, under a bit of oil and stuff which is from moving the head around I think - any one have any comments?
Next, and the bigger problem (when it rains it pours...). In inspecting the camshafts and the lifters I noticed that the 2 lifters which do the exhaust valves on cylinder no. 4 (all compression issues are with cylinder 2) are marked, not shiny like the rest, tried to take a photo but with the flash in my unlit shed it didn't work very well...
So, check the camshaft and the final lobe is worn almost circular!! How does this happen? Both are marked much more than any other ones... See the photo below:-
And from the top...
So - that's buggered, so I need 2 lifters and an exhaust camshaft - any ideas on where to get them!!
So - worth continuing with this head or just getting a recon one?
Everyday is a school day though, came apart in under an hour, though when you take nuts off studs and the stud comes out rather than the nut unscrew, is it better to put a new stud in?
P.S. - what is the code for imbedding images? I have hosted them in my photobucket account but they are only links?
