LPG Systems & Valve Saver Protector Kits

[shy7g]

Hi All
Does anyone running on LPG have any kind of a Valve Saver Protection Kit fitted to their vehicle?
Whats your opinion on them??? Are they a good investment??? Are they needed with today's engine???
thanks

I had a BRC kit fitted to my E61
When I went for the first annual service (in my ownership) I asked about valve saver, and was told that all recent German cars didn't need it as LPG is very popular over there.

mine is a 2002 4.4, had lpg fitted at40K in 2006 (On Purchase of car). was told valve saver kit NOT required and did no fit one, have done about 52K to date , going great.

Funny that this should come up actually
My 3l has one fitted and its been there since before I bought the car
I've always had problems running on lpg with bank 2 running rich but never been able to figure out what was causing it

Last Friday I took the car to a guy I know who is an lpg legend
He had the same problem.... We looked at lambda sensors and everything... One thing he mentioned was that BMW's don't need a flashlube
After a while talking and brainstorming we came to the conclusion that the flashlube was causing the problem because it was pooling in the manifold and draining down to bank 2
We closed off the flashlube and watched the fuel trims over the next 50 miles and slowly everything is coming back to normal

Never had one on my 4.6, and when I took the engine apart because of timing chain problems, the valves and seats were in very good condition
