Today is the first chance Ive had to look at the car after she went a bit wonky on the way back from Devon.
On the way back up the M5/M4 - the engine note changed slightly. So I stopped and had a quick look round the engine in the services. Seeing nothing obvious I carried on until about 10 miles from home the check engine light came on occasionally. This was also accompanied by a 'chuffing' sound - so Im thinking AIR LEAK. I managed to get off the motorway and limp home.
On initial investigation I found the number 2 spark plug had shaken loose and damaged the coil pack nose, so I ordered new plugs and a coil pack. The other plugs were all tight and I was planning to change the plugs this weekend had she been ok!!
Today however, I went out to change all the plugs and replace the loose plug. To my horror looking down the plug tube the hole looked 'different' to the others. It appears the plug has 'ground away' the plug threads inside the head due to vibration??
Now my question is (as the car only cost me £800) - is it worth saving? It is my daily driver and had been reliable UNTIL NOW.
1) Can the head be helicoiled in situ cheaply?
2) OR will the head have to come off leading to £££££££'s in repairs - (more than this thing is worth) and more than I have in the bank?
My other car - the C70 is also now dead and running on only 4 cylinders, previous to her going into storage she was running fine. I need to get up and down to Torquay every week and the options are now looking dire. I currently have a rental car which I cannot continue due to cost.
any ideas please? DESPERATE
