September 16, 200718 yr I am finally finishing up a HG job I started loong ago I was about to put the valve covers on....I have the 6 bolts and new grommet washers...but I see two more bolt holes in the VC in the center that tighten around the spark plug rubber gaskets. Can someone remind me what the hell these bolts look like??? I don't see anything in my bags of parts that go in the holes....or some kind of gasket washer either....this is the problem waiting a year to finish a job thanks 96 2.5 DOHC
September 17, 200718 yr There is not a bolt there. I have done two recently and those were empty when I pulled the cover. Probably a design to hold down the plug wires. Don't worry about them
September 18, 200718 yr For some reason those are only in the 96 VC's, the ones that say four cam on them. They are also the only ones that take that style spark plug wire.
September 20, 200718 yr Author There is not a bolt there. I have done two recently and those were empty when I pulled the cover. Probably a design to hold down the plug wires. Don't worry about them that sure seems strange as there is definitely a hole with threads in the head. The spark plug gasket (on the v cover) has a hole in it that the bolt would go thru(there are 2 in each cover) These sure seem like they should have bolts as it would draw the valve cover in tight and compress the gaskets well Anyone have a 96 ish DOHC and can look I could post a pic if needed
September 20, 200718 yr Take our word it doesn't use a bolt there. Look at your spark plug boot (assuming they are sube wires) they have a nipple that actually drops into that hole.

Look at your spark plug boot (assuming they are sube wires) they have a nipple that actually drops into that hole. sorry guys I do have subie wires and there is no nipple--there's a big flat flap on the end of wire that covers this hole along with the spark plug opening There is clearly a large threaded hole in the head to receive a bolt--2 on each side can someone advise how to post photos? this mystery is bugging me....thanks
September 21, 200718 yr The holes on the heads are on all DOHC 2.5's. When I saw them, I assumed they were for a COP (Coil On Plug) option. Never saw the wires that cover them though. there is no bolt that goes into them at all on the standard configuration. I have done dozens of these HG's. skip those bolt holes. It is bad enough that the wires sit almost right up against the frame rails as is. . . Adding a bolt there will only make your life harder as you maintain the vehicle down the road.
September 21, 200718 yr I am doing another set of HG's this time on a 99 and that also has the holes, along with the nipple on the plug wire boot that drops into the hole.
September 21, 200718 yr okay, several posters have said it.....there is no bolt for thaat hole. Now just go with the flow and finnish your engine.
