Well I’ll give you the rundown and I’ll start with a little history of the car. I have owned this car for three years with only minor issues and regular maintenance. The previous owner said he stopped driving the car because he heard a knocking sound so he took it to the shop and they supposedly pinned the cams. This was at about 84,000 miles. The car now has about 143,000 miles on it. I have not noticed any odd noises coming from the engine. Anyways…
It all started when I sourced an oil leak to the rear valve cover. Well today I finally had a chance to start tearing into it and I figured the intake needs a good cleaning too since I’d never done it. So that was the plan. I had no problem getting everything off meaning the surge tank and all. This was because whoever supposedly pinned the cams left out the bolts they obviously could not get back on. Well once I got the valve covers off I thought something seemed strange. I knew the cams weren’t welded, but the previous owner said he had them pinned, and I’m not sure what that is supposed to look like but I noticed nothing done to them that I could tell. However I did noticed marks near the sprocket which you can see in the pictures. Now I’m not sure if this was from when the previous owner had it or not but it has me worried. Here are the pics.
Intake side front bank.


Exhaust side front bank.

Intake side rear bank.

Exhaust side rear bank.

Another rear bank shot.

The three without the bolt object on them had the grooves in them. I’m assuming this is bad. So looking at this I’m assuming I need to get this thing welded so I need to find a place close to Ohio to get them welded.
Also I need…
-Valve cover Gaskets and Plug Well Seals (Where can I get these?)
-Plugs (Oil in one plug well)
-Coils (I’m assuming I might as well just get four coils for the back just in case)
-Clean intake, seemed like a lot of carbon buildup.
Luckily I just picked up something else for the winter and I was planning on driving it until at least March or longer if necessary, and parked the SHO, so I do have time on my hands. This is my first time digging into the engine of the car. Never had a reason too before. I would appreciate any input or advice though. Thanks in advance. I just don’t want to risk losing another Gen III to cam failure.
