Last Saturday I went to replace my spark plugs. When I got to #3 I found that I would have need far to much torque to get the plug out. I would have had to use a breaker bar. It started to make that noise, if you know what I mean, the noise of something is going to break. So I just put the coil back on and moved forward.

The same thing happened to #4 and so I moved on.

#5 hose went fine.

I am thinking of giving another attempt but this time I'll spray some penetrant down the hole and leave it soak for a while.

Good idea? I'm really not into having the threads come out with the plug or breaking the plug.

IF I am on a dangerous path, I'd rather just let those two remain in place and just keep the two overly expensive Volvo spark plugs rest in the cabinet.

 

Can't hurt anything - let it soak overnight maybe?

 

I was doing them for a just because maintenance. I didn't know when the previous owner replaced them. The gap on ones removed were bigger than what is required so I guess the tips were worn.

So on a just because maintenance I would be ticked if I snapped one. There is the times when doing a needed replacement and things go wrong but this wouldn't be a needed instance.

 

I used PB Blaster on my V70 to remove the plugs. Just sprayed it in and let it set overnight.
