Greetings everyone. I'm new to this and hoping someone can help.
My VR6 starts fine when cold but gradually increases in revs up to pretty much anything if you'd let it. Obviously need to shut it down by turning the key off (as much as I love listening to those 6 little puppies turning over at 6000rpm). Once this is done, it won't start for about half an hour.

There appears to be some unusual wurring sounds from the little round thing at the end of the head and the sound of gurgling water (as though there is air in the cooling system somewhere). Don't know if this is related. Hope someone can help me cause I haven't driven it for a few days and thats not good.
