#1: 2003 1.4i 8v cylinder head bolt torque problem Author: bill555, Location: ukPosted: Mon Feb 27, 2017 9:03 am ---- Hi guys,
Just changed the head gasket on my wife's 206, it's a 1.4i 8v. Problem has been a long term oil leak from the front of the head and more recently water in No.1 cylinder (gearbox end). Torqued all the headbolts in sequence to 20nm, then +240deg in the same sequence. Everything went well except for the last headbolt which got to about 140deg and would not go further without what I believe would have been destructive force accompanied by lots of extreme noise and judder. Anyway my problem is where do I go from here? Do I leave it alone? Do I remove the bolt and try again? If so to what torque and angle? The head is pretty much pulled down so different start position now. Perhaps I'm worrying too much.
Any advice, ideas or comments would be appreciated.
Bill.

They are the original bolts, all well in spec, threads cleaned, engine oil on thread and under cap. block threads chased and cleaned. I appreciate that this is a friction problem with this one bolt, could be bolt or block threads or both. With hindsight I would have used new bolts, I need to put this down as a learning exercise and work out how to proceed from the point I'm at.
