4V Rear Spark Plug Tunnels Too Narrow
I'm wondering if anybody else has had a problem with the rear spark plug tunnels being too narrow for the socket to go down on 2001 4V heads. I tried 2 different brands of sockets and had the same problem with both. I was able to get the #4 plug though it was tight, but wasn't able to get the #8. Is there a defect with some of the head castings? I also noticed there was a lot of a light brown dried residue of some substance in #7 and #8. I'm the 3rd owner and I think the plugs were the originals as the car has less than 10K.

Could the brown be dried up di-electric grease?

No problem here. I use a standard spark plug socket.

Re: 4V Rear Spark Plug Tunnels Too Narrow
Could you try a standard socket, not a plug socket (IE deep well 5/8" or 13/16" depending on size)?
Usually the plug sockets are slightly thicker wall thickness.

Re: 4V Rear Spark Plug Tunnels Too Narrow
Thanks for all the info. The substance could be dried up di-electric grease. All of my previous experiance is with OHV engines, so I never had a place for the grease to dry up in. I could try a standard socket, but then how do I get the plug up out of the hole? Is there another tool I should get? I will also check the gasket.

You can get a good magnetic flex tool, generally the top of a plug can be picked up by a magnet. Or take the foam insert out of the plug socket, wrap it with a few layers of duct tape and shove it up into the standard socket.
