Today whilst heading to the car club a fellow car club member was travelling behind my Mk6, he told me that on the steep downhill run there was a puff of blue smoke from the exhaust. Speed at the time was about 90 km/hr. I understand that this is caused by oil leaking through the inlet valve seals. Should I be concerned about this? I understand there are new plastic seals available to replace the asbestos string should I be replacing the seals? The car does not seem to burn oil excessively. | ||

Sounds like the valve seals. They are easy to replace and its your choice regarding the string type or the "new" type. I changed mine last week and used the string ones. Just soak them in engine oil for 24 hrs prior to fitting. The new type require the sharp edges on top of the valve guides to be removed before fitting them. They work very well but can starve the valves of oil but in a worn engine this should not be a problem. | ||

Thanks Trevor, Hopefully the engine is not too worn, will do a compression test this week, but when I checked a few years ago it was pretty healthy. What tool did you use to keep the valve in place or did you remove the head ? | ||

You do not need to remove the head. Remove all the spark plugs and then I just feed a foot or so of 12mm nylon cord through the plug hole and then bring that piston up to TDC and the valve will be supported by the rope that will cause no damage. If you want to make up a tool remove the ceramic insulator from an old plug and then drill out the center to accept a 1/4 rod that can be bent at the end to support the valve when screwed into the plug hole. The "rope trick" works well and I have used it on several ocassions | ||

Thank you Trevor, the rope method sounds like the simplest way to go | ||
