Accent LC (2000-05) :: Check Engine Light Code P0422 / Slight Valve Cover Gasket Leak

I bought the little car to get off my motorcycle and its done great. But, after a couple trips around town my check engine light came on, and I imiditely noticed a change in my idle and engine performance. Im assuming my engine changed the air/fuel ratio to account for the sensor indications. My initial code read came back with four codes which said something about spark, and O2 sensor, and emissions. I went ahead put new spark plugs, gaped them as well as replaced the first O2 sensor.

After that I reconnected my battery and sure enough no engine light and my idle felt even better than before. (by the way my old plugs looked normal) But shortly down the road the light came on again. My idle did become a little different but not like my first encounter with the engine light. My power too seems a bit degraded, as well as the engine's sound. As of right now I am only reading one code P0422, which I do not see in the manual. I read online that its probably my catalytic converter or my engine is running at an improper air/fuel ratio. I am praying that it is not my catalytic converter and just my engine computer throwing things off.

Other things which may serve as clues:

Slight valve cover gasket leak (I will change the gasket when I do my timing belt job along with other seal and probably the water pump)

When pumping gas I can get about 90 cents in at a time, now more like 40 cents since the Saudis lowered our gas prices. Assuming I've got some kind of venting problem.

Car has 107K manual shift.

Accent MC (2006-11) :: Valve Cover Leaking?

Haven't had the engine cover off for about 25k now (cleaned it up under there last time I changed plugs.) Took it off today and noticed it's a little oily on all four sides around the valve cover.

Pretty sure I can account for the oil that's near the filler cap... I don't recall spilling enough that would completely go around the entire valve cover though...

But how did it end up so high on top of the valve cover on the corners? It's even a little wet looking on the back if you look hard enough..

I only have 4600 miles left of the 10/100 warranty so I'm glad I caught this and hope the dealer can do something about it... or are they going to tell me this a "normal" amount of seepage? I haven't owned a vehicle with plastic valve covers before so I don't quite know what to expect.

Toyota - Tundra :: 2000 - Very Low Power After Replacing Valve Cover Gaskets

Truck was running a little rough before valve cover gasket replacement. Replaced gaskets and it ran rougher than before. Found a burned out spark plug coil and replaced coils, plugs, and wire. Runs smoothly now, but there's very, very low power, probably tops out at 35 mph. What gives?

Accent LC (2000-05) :: Driver Side Floorboard Have Water Leakage

2003 Hyundai Accent 4 door. Well its been raining here in Portland Oregon non stop and this morning I went to get in my car and smelled a mildew odor so I took out the drivers floor mat and the carpet was soak. Then I laid back the carpet and that grey spongy covering thats under the pedals was soaked to the bone like a sponge.

I did a test with a water by putting the hose on top of the roof of the accent and turning it on full bore and nothing leaked in the car. I sat in their for a good 5 minutes with the hose blaring down the windshield and door sides. I even took a jack and lifted the car up too see if there was any cracks or a rusty hole underneath but nothing. So Im completely stumped on this I do have A/C and the drain hose is clear since I have been using my defrosters and the A/C pump kicks on.

Corolla / Matrix 2009-13 :: 2ZR-FE 1.8L Engine Valve Cover Bolt Torque?

I looked around and couldn't find the specs for the valve cover bolts.. I'm assuming it'll be a pretty low torque like 20 ft-lbs.

This'll be the 2ZR-FE 1.8L engine.

Golf IV / Jetta IV :: Engine Won't Start After Replacing Valve Cover Gasket

My mk4 sat for a while and upon starting up was misfiring. I checked for pvc leaks and didn't see anything but went ahead and cleaned my maf sensor and decided to pull my coils. Cylinder 1 had oil on the tip and around the spark plug which to me spelled out a bad valve cover gasket. I got all the parts to do the inner and outer gaskets and replace the coil and spark plug, however we got a snowstorm and my luck a rabbit got in and ate the wiring on one of my fuel injector connectors.

So went ahead and put on the new gasket, replaced the coil and plug and bought a new Fuel Injector Connector and spliced in onto the Injector "Pigtail'. I double checked everything was reattached properly and let the gasket sealant dry for 24 hours. I went to start it tonight and after trying to turnover it completely cuts out, wont even start up. I'm extremely frustrated at this point and am thinking the rabbit must have gotten to something else unless I did something wrong in the process of repairing.

Passat (B6) :: Small Leak From Back Side Of Engine - Valve Cover

Today I did a oil change (70k). While under the car I notice a small leak from the back side of the engine. When I got home, I had the chance to remove the engine cover to investigate and clean the engine up a bit.

I found that the bolts in the rear of the valve cover had a little puddle of oil around them. I took a T-30 torque bit and was able to get a least a full turn on the rear bolts and about half turn on the middle ones. Fronts were about a quarter turn. Check your valve cover bolts.

Celica :: 2000 - Engine Oil Leakage 2000 From The Rear Of Motor On Driver Side

My 2000 celica is leaking engine oil from the rear of the motor on the driver side ( passenger side for the U.S). the oil drips are quite insignificant at the moment with only a small amount leaking on the garage floor, but a leak is a leak and i want it fixed. ive tried my hardest to find the source of the leak but i just cant squeeze my head in well enough to see where it is coming from as the engine bay with the 2zz motor is pretty tight! the car only has 116k KMS on the clock (72k MILES) and is regularly serviced so it doesn't make that a seal is on its way out already, but from the area that ive isolated it to, it looks like its the crank pulley or seal....

Ford 6.7L Power Stroke Diesel :: 2011 F250 - Oil Leak On Right Side Of Engine Above Valve Cover In The Middle

I have a oil leak that I can't seem to find it appears to be leaking down above the passenger side valve cover and then goes under the engine cover. I don't notice much oil in the valley. This is a 2011 f250 6.7 with 116000 miles on it. I have had no other problems with this truck. Could this be the turbo lines? I am on a RV trip several hundred miles from home so I have very limited tools. The leak doesn't appear to be bad at this point the valve cover is wet with a small drip but it's only in the middle. I just changed my oil prior to the trip when I noticed the leak. I did have a leak on the new filter but a new filter fixed that but still have this one higher up.

Accent MC (2006-11) :: Chirping Noise Coming From Under The Engine Cover

My car has been making this chirping noise for a couple weeks now, and I can't figure out what is causing it. It's really bothering me.

The noise is sinked in with the rpms. While in neutral or while I have the clutch in, the noise stops. The higher the rpms I'm running, the faster the sound goes. I opened the hood the other day to see if I could figure it out, but all I found out from that is it sounds like it's coming from under the engine cover.

Engine? Maybe a component near it? Maybe it's just the cold weather constricting parts to a smaller size?

Lexus RX 2010-15 :: 2013 RX350 Oil Leakage From Timing Chain Cover

I have a 13 RX350 with 10,000 miles with a side engine oil leak. I looked underneath and I think it's the timing chain cover seal. Took it to the dealer and they put dye in my oil to figure out where the leak is coming from. They suspect it to the timing chain cover as well. I am aware that 07 ES350s had a know oil leak coming from the timing chain cover but haven't heard anything about the RX having this issue. My service rep said they would have to remove the engine to fix the leak.

Accent MC (2006-11) :: Engine Valve Knocking On Slow Acceleration

I have yet another issue with my Hyundai Accent. It seems to me that I hear engine valve knocking. Here tech. details:

- This happens around 1100-2000 rpm.
- The car currently has 11500 KM.
- 3 oil changes so far - using Mobil 1 - 10W30.
- I put in regular gas.
- No mods, only bug guard.

I drive slow - slow acceleration and I noticed sometime ago that there was a knock coming from an engine at about 1400-1700 RPM, however now I can hear it anywhere from 1100 to 2000 rpm. I can hear it very well when I drive along curbs and walls since engine sound bounces off it. I have automatic gear box and therefore I don't know how to test it further ( on manual I would have put some load on the engine by switching into high gear and pressing gas - make engine struggle a bit ). It might be noise from injector but I don't know. Also I don't know if Accent 2010 has self-adjusting valves or not.

Accent RB (2012+) :: Check Engine Light Came On - Purge Valve Replacement

So sometime last week my check engine light came on. Took my 13 Accent to the dealership and they said the purge valve is to be replaced. Now my Accent pings when running 87 gas and I read that others (not necessarily Accent owners) who changed their purge valve noticed the pinging go away.

Golf/GTI VI :: Valve Cover Leaking?

I had it checked out at the dealer and they called it a "weep" so they went on to tell me that VW probably wont approve warranty work for it. I pushed for them to take pictures and send it in anyway.

Now assuming they won't do it, I have been looking for a DIY or a technical order on the job but I can't find anything.
