Low/Rough idle on every cold start

could be a leaking head gasket and what happens is that coolant is leaking into the cylinder after you shut it down.When you crank it up in the morning it has to burn that coolant up there for skipping , then when it burns that up it runs fine.... Had a few 240 has this problem and it never ran hot but leaked into number 1 cylinder.... After i shut it down after about hour or so driving and took that plug out I could see coolant going back into that cylinder. I took a mirror and placed it over that cylinder with the plug out and yup it was coolant for sure...

ill surely have to take a look at that and let you know what it is, i can probably do that today, but as far as the head gasket goes, that won't be until i get my christmas/new yrs vacation when it starts on the 26th. Is the S14 sr headgasket the same as the s13 sr? I've found plenty of part #s for the s13 sr
