My XK8 just woke up from the winter.
Hi Guys, before I put her to bed last fall ( I'm in Canada)I was having a restrictive performance issue. I tried checking the plug wells and no oil, it runs great for the first 25 minutes and then the light comes on and it's restricted. I noticed after it ran for about 25 minutes ideling yesterday, there was oil smell . Before I start to pull stuff off the engine and look for the leak does anyone have any ideas? I bought a gasket kit for the valves and plugs but when I checked the spark plug wells and they were dry, I didn't put them in. I may have to start relocating the coil in the cylinder that keeps coding misfire to see if it follows the cylinder before I start replacing coils. appreciate any feed back. Over the winter I tried to order a new bumper ( it was damaged when I got the car) I ordered a veilside ( spelling???) I waited about 3 months and finally called on delivery and they said they stoped making it for the XK8. I checked for just a replacement and they wanted about a grand with shipping. I decided to fix mine, I reinforced the damage from the back and decided to change the look, It's almost ready to install, it resembles the 2007 now, I'll post some pictures after it on. Save a bundle. Thanks guys

Hi Reverend
Yes, I did the code, I guess it would be helpful to you guys.... Hey!!!
There are 5
P0302 Cyl 2 misfire
P1313 manufacture control ignition sys. or misfire.
P1316 same as previous.
P0352 Ignition coil B primary/secondary circuit malfunction.
P1000 manufacturer control fuel & air metering, aux. emission controls.
I erased everything but the last one would not clear after a few tries.
The thing is it's not consistent, it runs fine for the first 25-30 minutes then codes restrictive perf. and then clears maybe after another 30-40 miles and codes again could run fine for a few days and then starts all over again.
I was going to try to move the #2 coil around to see if the code changes with where I put it. Where is #2 because it calls each side A bank or B bank and then 1-4 on each side instead of 1-8.
thanks for your help. This site is awesome.

It looks like a bad coil, or maybe a spark plug. #2 is the second cylinder from the front on the right side of the car. Swap a couple of coils around and see if the problem shifts to a different cylinder. While you have the coil off of cylinder #2 go ahead and pull the spark plug to see what it looks like.

Thanks Guys
I had changed the plugs last fall, NGK iridium. They look fine and no oil in the holes. I'll try moving the coil around. Do you know where else I could have an oil leak ? I get the smell of oil and a bit of smoke under the hood after it gets hot. I pulled the vavle covers off last fall it it didn't look like it was coming from there. There isn't any oil under the car on the ground.

I pulled them off because someone told me I might need gaskets but it didn't and I reinstalled the covers and drove it for another month. I got the smell of oil last fall and obviously now. It can't be leaking much because the oil consumption isn't out of the ordinary. Could there be a loose hose, maybe from the air intake or emissions that would leaking? This is my first jag and don't have much knowledge of this engine.

Hi Reverend
I used you diagram and swaped the #2 and #4 coils and plugs. The plugs had a little too much carbon but not sure if that's from running restricted performance???? I ran it after I switched the coils and it coded P0354 ignition coil d Primary/secondary circuit malfunction. The other was P0304 Cylinder #4 misfire detected. Which was the one in #2. It seems like it's that coil.
