Morning all Looking to tap into the fountain of knowledgeable K series engine people on here! I currently have a Superlight R which I picked up almost a year ago. It has got a VHPD K Series engine in it that has been fettled by Dave Andrews and is now pushing 216bhp. It's a dry sump engine. I had my first track day this week with the club at Castle Combe and the car ran like a dream pretty much the whole time but, occasionally, there was a slightly worrying noise on start up. After a session on track, and after a period of rest before the next session, when starting up it sounds terrible as if it has no oil in it. After about 10, maybe 15, seconds it settles down and the noise goes and the engine runs perfectly with no other signs of issues. Occasionally it has happened at other times after some spirited driving. It's as if it is taking a short few moments to pump the oil around the engine. Is this normal behaviour for a dry sumped VHPD K series engine? If not, any suggestions on what to look at? If it is normal 'd rather be slightly paranoid about the noise than ruin an engine! Thanks
