Top End Noise & Poor Accelleration

Not exactly the way I would like to start my evening after a day of work but not my choice. The car has been making a ticking/rattle noise at startup like a bad valve rocker or something. I didn't think much of it as it goes away with a second or too. On my way home tonight I took the eway and noticed it seemed a little sluggish shifting and getting up to speed. It was almost red lining before shifting. Once I was at speed the car seemed fine. Once I got off at my exit I noticed an drastic acceleration problem and the car was not running right. There was a loud noise when accelerating and a slight shimmy. I babied it home.

I poppped the hood and noticed that the engine was smoking. My worst fear was that something blew and there was no oil in the engine. I immediately checked the dipstick and there is still oil. THANK GOD. I let it cool off a little before turning it back on to try and diagnose it further. The noise is definitely coming from under the valve cover. Again it sounds like a bad valve rocker but also has a roaring sound with it. I would describe it as being similar to if there was a leak in the exhaust.

There is no check engine light, I may hook up the reader just to see if anything is present. I think the first plan of action is to remove the coil over setup and check the spark plugs. You would think it would throw a misfire code but who knows. If none of the plugs looked fouled I guess its time to move to removing the valve cover. Anyone have any suggestions?

How long has it been "ticking"? Mine makes a slight ticking noise, but it always has. I think you are on the right track for figuring it out. If you have to crack the valve cover check your timing chain and tensioner, especially the guard for execive wear on the plastic blocker.

I'd take the valve cover off and check before I started it again.

The car only recently started to make the ticking noise after I did an oil change. The only thing different with this oil change is that I used a high milage synthetic instead of the normal mobile 1 I had been using. I did note that its only been a couple weeks and the oil seems a lot dirtier than normal.

I checked the plugs and they all looked fine. Cyclinder 1 or whichever it is closest to the passenger side had fresh oil on the threads This may be a sign that its starting to foul but not sure. The others has some burnt on oil. Car just sounds bad when you give it gas. I guess the next step is to remove the valve cover

Ok I pulled the valve cover and found that there was a small fur ball object down by one of the valve springs. I also found that there was a sluggy/sandy substance throughout the valve cover. I am wondering if this wasnt some residual sandblasting material from when I had the valve cover powdered several months ago. I also noted that the valve cover gasket is warped and no longer fits properly and that the front oil passage on the left looks spotless. Almost like no oil has ever gone there. Kinda strange

I have posted a series of pictures below to show different areas of the engine and valve cover. Please let me know if you see anything out of the norm as I do not have much experience which engine internals. You should be able to see what I am talking about with the valve cover.












My plan of action unless anyone else has some advise is to start by cleaning the crap out of the valve cover to remove all that sludgy substance. I then plan to get a new gasket set and put it all back together. Finally I think its a good idea if I do another oil change. I think I may go back to using my trusted Mobile 1 instead of the high mileage stuff I used last time. Whats everyones thoughts of this.

I didnt press down on any of them to see if they were loose but I can do that tomorrow after work. As for the compression test I don't really have the tools or know how to do that. If I can't figure out the cause of it I will most likely be taking it to a shop.

you can rent a compression tester from any auto parts store. you just plug it into each of your spark plug holes and crank the motor (take out fuel pump/ignition fuses) and that might help diagnose the oil on the plugs

i just thought of something... pull your water pump cover (the 4 bolts and cover by your motor mount) and see if the water pump/balance shaft chain is still tight and on there. if not, there's your problem. happened to me once, my car hated life

agreed on that for a compression test. Ensure that your within specs to it. If one cylinder is lower than the rest, check your valvetrain, can be a broken valve spring, lifter, or broken lobe. If 2 cylinders (companion or opposing), check your head gasket, may have cracked. If all, then its your bottom end, aka crank.
