My van spat a spark plug out last night. After initially thinking it needs a thread insert I spied a crack from the photo I took? Please just confirm I am right? There is a hairline crack leading from the inside hole along the thread and out isn't there (before I take the engine out and start ordering new parts!) (You may need to zoom in) Thanks
yep....new head or get the old one stitched...http://www.hthoward.co.uk/engine-machining-services/?gclid=CP3xru6_-7sCFYUewwodASkAeA give them a ring for a ball park figure....
Yep that doesn't look too good. Check your other plugs too. I had a similar issue years ago as a result of a loose plug. The hot gases escape until it can't hold on any more. You can see the sooted line where yours has been blowing Bummer
Its cracked and the best approach is to get a new head It has been known for people to chemical metal the plug in place untill they can afford a new head
Thanks for the replies folks. I dont have a lot of time these days since we moved house recently so I will just put forward my plan for a top end overhaul now and get it out of the way. The amount of work to remove and strip engine might as well get its major service done. Its a good engine and served me well so deserves a decent fix! Thanks again
