THanks for the help but all to no avail No4 pot full of water.The garage did a test by putting a tube device in the top of the water bottle with the engine running and the gasses from the bottle turned the liquid in the tube green which indicates that gas is leaking into the water space ergo! HG gone, so off with its head!!!!. Thanks for all your help and advice. Mac
Hi Boys, Changed the rocker cover seals today as there was a lot of oil in the plug wells, thought that might be causing lumpy tickover but there was little or no Mayo in the cam box only a bit in the brthr pipes.Car still runs super but tickover lumpy when hot. Mac
Hi boys, THanks for the help, did`nt realise the plugs would go white, one does look quite clean, local garage is going to do a block test tomorrow to test head integrity, anybody know what this is and whether its effective or not?.I refilled the bottle today and took car out.When I got back the bottle was empty, when I removed the cap the coolant just gushed back into the bottle again.Tickover is also lumpy. Is this related?. Mac
I notice that the coolant level in the tank has started to go down slowly over the last few weeks , I cant see a leak. I had the head replced 1 year ago after belt broke, been going fine since. Drives fine but concerned head might be leaking. Should the head be tightend again.
