I assume it's 16 valve from the year? If so I wouldn't worry too much about the head being cracked, have never heard of it happening on these engines (C20XE's without the coscast head are the vauxhall engines famed for this, although I've never heard of someone having one of those crack either  )
If it's 8 valve you've got even less to worry about, it'll run without oil and water for weeks and still come back for more  (slight exaggeration but they're bombproof)
Either way it almost definitely needs a head gasket change imo!
Also it wouldn't be unusual for a smaller engined car to warm up faster, especially if it's the smallblock variant in the range, less casting to warm up and also my little 1.2 8v regularly sees 4k revs daily in order to make it move rather than crawl, wouldn't be doing that in a larger engined car... I really wouldn't put any problems down to that, or agree they *need* a smaller engined car though. All 1.6 vaux engines I know of are smallblock anyway. |
so why would you knock a low usege car that hardly reaches temp with some emulsification for a head gasket, ? when we dont know if he is looosing any coolant, only problem he had was running fine but light on and knock.
personally i dont knock things like that till i have all the symptons.
he would have to be loosing coolant for it to emulsify in the engine,(coolant going into sump).
