Rocam1.6 06 model uses oil sparkplug No2 gets wet with blk carbon, misfirin smokin white.If I change tht spark plug it goes well For3 days.Mechanic changed the rings after 6 weeks problem persists.hlp


The carbon suggests that oil is finding its way into that cylinder and oiling/carbonising the plug.

The mechanic changed the rings so it's doubtful that the oil is finding its way into the cylinder, past the rings. The only other thing I can think of is that the valve stem guide is worn (this would allow oil down into the cylinder) or the valve stem seal is perished/worn.

The photos below are generic images. They are NOT of your car:

26063798-uep1qeforvmfktksxbn30q5u-5-1.jpeg The seal itself - rubberised.

There's many different types of seal. General image below just for illustration purposes:

Bluish smoke indicates that oil is being burnt in a cylinder. To be honest, worn valve guides/worn seals are quite common. You say your car is misfiring? That would indicate quite a lot of oil is fouling the plug. In most cases there would be no misfire after just 3 days. The exhaust would cough out bluish smoke at start up and maybe on the over-run, when going downhill.

A short term measure is to try a can of valve seal additive to see if the problem temporarily goes away. Repair is the best option though.

Try a can of valve seal? It's worth a shot..

I have a 95 buick regal 3.8L. I changed the valve cover gaskets and after I was done the car idles rough. I did a vacuum test on it and it indicates that its a worn valve guide. Is it possible that I got a...


Anything could have caused that, it is unfortunate! I have that engine on my Bonnieville, and it is a great one!

Please check any other possible cause first!

You should note that the 3800 engine uses integral valve guides. IE; they are a part of the cylinder head and cannot be replaced. They can be reamed oversize if they are found to be worn past the appropriate limits. Sometimes, the valve guide bore will be oversized as manufactured. This will be marked on the inboard side of the cylinder head on the surface just above the intake manifold.

This could be fixed by reaming and replacing the guide with oversized stems.

If you need more info let us know!

Considerable oil consumption with no visible leaks and a p301 code on my '01 e-250


p301 indicates number 1 cylinder is misfiring,that with the oil consumption, would indicate either worn valve stem guide,or worn piston rings to check you need to carry out a compression test,if compression is low the head would have to be removed to see which of the above is the culprit

ONE FOULED SPARK PLUG


Either worn valve guides, valve guide oil seals on that particular cylinder, or worn piston rings. You need to perform a compression test to find out which one of these it is.

Compression check each cylinder with all plugs removed. Take notes on which cylinder has the weakest compression.

If no compression difference and if all operating within range, then change the valve guide oil seals on problematic cylinder.

If the cylinder shows a significant drop in compression, then drop no more than five or six drops of oil down the plug hole of the problematic cylinder, and perform the compression test again. The oil will temporarily seal any worn piston rings, so the pressure should rise when retesting if the rings are worn. If the pressure remains low, then your valves are not sealing properly and require attention.

Why does the van smell like gas when i come to a stop


If the engine is buring oil, it usually smells like burned toast. Check the oil level on the dipstick to see if the oil is low (add oil as needed to bring it back up to the full mark. DO NOT let the engine oil level get too low or serious engine damage will result!. Do a compression check or leak down test to diagnose worn pistons or rings. The underlying cause may be worn or broken piston rings, worn or damaged cylinders, worn valve guide or valve guide seals. A PVC valve could also be at fault leaking oil into the intake.

My timing chain sounds loose. can it be adjusted or should it be replaced? 2003 nissan altima 2.0


If it is running loose for a long time and is worn then should be replaced as soon as
But if the tensioner has come loose which it shouldn't have then an inspection of the links will further tell you if it should be replaced.There are ways to inspect the timing chain.This is a rough guide.

Timing Chain and Sprockets Cleaning and Inspection
  1. Clean the components with cleaning solvent.
    Caution Wear safety glasses in order to avoid eye damage.

  2. Dry the components with compressed air.

  3. Inspect the timing chain for binding or wear.

  4. Inspect the camshaft and crankshaft sprockets for:
    • Worn teeth (1)
    • Damaged teeth (2)
    • Chipped teeth (3)
    • Worn valleys between the sprocket teeth

  5. Inspect the crankshaft sprocket keyway for wear.
  6. Inspect the crankshaft sprocket oil pump drive splines for wear.

  7. Inspect the chain guide (232) for the following conditions:
    • Loose metal inserts (1)
    • Cracking (2) in the chain contact area
    • Excessive grooves (3) in the chain contact area Grooves 1 mm (0.040 in) or less in depth are to be considered normal wear.

While starting car little smock come for few mnt why ?


If you get a little puff of white/blue smoke just at start up , it probably means that one or more of your valve guide seals are worn.
While engine not running , a bit of oil gets in the cylinder , when it starts the oil burns off causing smoke. If it was smoking all the time , I would say rings are worn. If it is black smoke at start up , it indicates a fuel mixture problem. The valve guide seal problem may get worse over time.
On your post you say " for few mnt " if that means a few moments , than Valve guide seals , if you mean a few minutes , than more serious piston ring problem. Change your oil , and add a can of RESTORE , it will fill small scratches in cylinder walls , but will not fix badly worn rings.

Burning lots of oil . but gasgets all ok.and need to know if can slightly speed up engine without computer assistance. 1.8 st celica n.reg.


You must have worn poston rings or worn vavle guide seals causing the accesive oil burning. As for raising your engine idle speed, it can be done by adjusting your idle screw, but it's not recommended. Factory idle is about 700-750 RPM.
