hi 2006 RR SC, 69k with BRC LPG kit on drives great but the last couple of days in the morning i get big cloud of white/blue smoke on startup it clears and all seam ok. it did it agin this morning, is this valve stem seals already at 69k? or is there any common issues that anyone else knows of?

cheers

Would seem like VSR due to the LPG kit? Does it have flashlube? Don't here of too many people on here that have suffered with VSR

Hi yes it has flash lube. It looks like the oil pipe is tee into the the 2 round lpg units that feed the gas injectors. The lub has dropped alot more than usual.

If you over lube it, it will smoke like a pig...

I had another look at the flashlube bottle setup. There are two lpg regulators with what looks like a vac hose coming off and going under the engine cover. The lub bottle is tee into this. I turned the screw valve on the bottle it only turned about 3/4 of a turn to close off. Didn't seem muvh

Hi all, just had my 4.2sc with BRC and flashlube serviced and was ok. A few weeks later and just had LPG service, guy upped the flashlube drip as was hardly using any and now I get thick white smoke on startup a and no other time. Just switched it off for 10 mins started it again and no smoke. The car is parked on a steep drive. Oh and at regular service had new coolant bottle.

Panic ye not , it'll just be the lube oil for the lpg system , depending on how its plumbed in

Cheers, seeing the LPG guy this morning. Totally trust him even though I have only just started using him as he showed me that others hadn't been servicing the car despite charging me for the last 4 years!!!! Current:

Smoking from car no fixed. Too much valve saver fluid was the culprit. Very very happy it wasn't anything else. Current:
