i have a freelander 1.8 which has had the head skimmed and replaced due to hgf but there was no compression on building back up so took the head off and put another gasket on and rebuilt it but still no compression! took the hydrolic tappets out and refilled them with new oil and replaced them still nothing! im at my wits end and tomorrow will try a tow as the last resort as ive been told it can help get the compression back ! any advice would be appreciated thanks
