I would get the oil pressure checked as the vvt will not work if it is low.....

Well i think i know why im getting liw mpg. Sometimes i notice heat in the car yesterday i checked the central blowers and air was coming out even though heating was off i turned it on set the temp lower and then turned it off bur they still blew air out. Today so far its orite. Thermostat gone? How much for a new one?

Can someone post a picture of where exactly the turbo is on a MK I vRS?

Thanks.

About on the car centreline, between the engine and the front bulkhead (aka firewall).
