pmh Posted June 9, 2015 Share Posted June 9, 2015 Has anybody got experience of using one of these? Is there enough clearance inside the head?Alternatively does anyone have one to lend or sell in Herts/North /WestLondon area.http://www.workshopping.co.uk/product/reverse-action-spark-plug-thread-chaser-14mm/MS003/I am reluctant to use a conventional tap as the the thread looks very good at top (But probably self cut!) and the bottom half looks good, with damage about 1/3rd way down.

Steve AKA vitessesteve Posted June 9, 2015 Share Posted June 9, 2015 I would be wary of any swarf falling into the combustion chamber whatever tool I used. Quote Link to comment Share on other sites More sharing options...
Stuart Wilson Posted June 10, 2015 Share Posted June 10, 2015 cover the tap with grease and keep taking it back out cleaning it reapply grease and repeat. The grease holds on to the swarf. What we did years ago on the vauxhall astra alloy heads when the spark plug threads weren't the best Quote Link to comment Share on other sites More sharing options...
