Hi guys had a few serious problems with the rst recently, ive had bad over heating problems which has lead from one thing to another, my over heating started with just over heating then it lead to having some serious compression inside my coolant tank the coolant tank at one point got so big it touched the side of my engine. ive had a compression test one the car which told me the head gasket is fine, we then found that the thermostate had melted changed it still got over heating issues,

I also had a bad miss fire, a couple of weeks ago i checked plugs to find that the gap was miles to big, so i re gapped them to 20thou, after this the car run perfect as ever the garage who have my rs now have put some new plugs in and it started miss firing the plugs have been gapped to 20 thou, so we brought some new ht leads and it still seems to be miss firing now the garage ive gone to arnt a rs specilist but there not bad so im thinking with the plugs they may not have been gapped proper.

please tell meyou surgestions and what you all think would very much appreciate it.

cheers
tom
