A quick update the helicoil seems to be holding i did a 200 round drip and the helicoil / glue held. Tomorrow i need to do a 100 mile trip am i just getting lucky or? Will this loctite 2700 hold the helicoil in ?Has i said i did a 200 mile trip 100 mile and then stopped made sure the spark plug was not lose left it for 2 hours t col then came back and car was fine but not tmorrow i have to go back not the motorway were it came out the last time.Any tips of not putting the helicoil under pressure?

 

I can't help with your question (outside my knowledge base) but enjoy your trip. Business or pleasure?

 

I have to take my kids home to there mother I see them once every 2 weeks the last contact i was on my way up to get them and the plug blew out so had to miss it because it took me days getting the car back from no were. So its been a month since i seen them ive had them this week end and have to take them back tomorrow. Down the same motorway i drove to the train station then caught a train there and back. But not hoping to drive down the same motorway. I use to be a mechanic for 4 years but have never put a helicoil in intill this happened to my car a friend who has been at it longer than me told me just now if my engine got to 150c there would be no engine at all but i explained the glue is on the threads of the spark plug hole threads / helicoil and was told it would be fine.

 

It should be OK - I can't imagine it getting much hotter than that, as the head has to be well-cooled as it's aluminium.

 

a quick update i made the trip up the motorway with it and it held i was going around 60 all the way tho. I was hoping to stop at the other end and let the engine cool down but couldn't so came right back with it and car was perfect so now hopefully it will hold till i can afford a new head

 

It'll still be there in ten years time, you watch.
