Points to note:- In the SVT set up with the oil cooler/heater behind the oil filter you can, if the filters are overtightened, cause the seal between the cooler & the block to fail.The cooler has an 'O' ring seal between it and the block with a throu bolt to which the filter screws onto....with care in this area...! .When you remove an overtight filter you can loosen off the cooler seal!
