I have been playing today,

I had to get the beast . due to other cars battery failing on me, cos its bloody cold here in the uk
drove the X the noise is getting loud

one of the lads on the FB page suggested, the lucas stop leak, and as I had a bottle of this, I sucked some of the old fluid out, which looked like babies yellow, (if your a parent you will know this) I had some ring rld04 in to diagnose oil leak
so threw a full bottle in
ive only drove the car maybe 10 miles, but I "seems" to have quietened down?
just waiting for my indy to drag it in, then they might haha, be able to diagnose it
