1.8 NA showing strange symptoms on start up. When cold there is lots of steam from exhaust with slight smell of coolant. When warm all symptoms disappear. Have done compression test (180/190/175/165), coolant block test (very slight colour change) and a coolant pressure test. Nothing conclusive.
Believe it to be head gasket (educated guess) but how can I tell if it's a cracked head?
Probably not related but no. 2 spark plug keeps fowling up. Any ideas? Cheers.

Hi Fran- was hoping you'd reply to this as I saw a previous posting re something similar!
Changed all plugs about 200 miles ago; 1,3&4 are all perfect whilst no.2 is dark/oily. Any ideas?
Should also say that when warm does not overheat although it is a bit flat. Have checked timing belt and it's spot on although haven't checked dynamic timing yet. Cheers.

Stripped the engine down and replaced the head gasket. Whilst I was in there I did the timing belt etc etc. I also spent an hour stripping and cleaning the hydraulic lifters as they were chattering a bit on start up.
Sadly it's still showing some of the previous symptoms; occasional white exhaust.
No2 plug is also still fowling. Any ideas on what might be causing that?

Checked flatness with a straight edge and was spot on.
Didn't check if valves were sealing.
Picture of valves...

No2 looks pretty nasty doesn't it? Any ideas?

Oil usage is hardly noticeable so not much help there!
Will do another compression test I think. Thanks Fran.
