Thanks for the advice so far. The leak from the drain plug is now sorted thanks to some PTFE tape. I mentioned in earlier posts about a leak on the passenger side of the car on inspection I have found that the leak is coming from a part that sits just above the oil filter and has two rubber hoses connected to it, it leaks coolant from the back which runs down and along the sump and drips off on the passenger side of the sump, so I only have the one leak on the part mentioned above, can anyone give me an indication what this part is and does please is it easy to remove, replace, renew etc. Is there an how to on the forum?. Thanks again in antcipation of your help.
