I have a 2006 Infiniti G35 base sedan. The dealer noticed oil on the engine and said that I needed to replace both valve covers and gaskets -- My question: Why is it necessary to replace the valve covers and not just the gaskets?
View 6 RepliesI took it to the stealership to get the alternator and some vac. lines replaced all under an extended warranty. They informed me that both valve cover gaskets and right side cam adjuster gaskets are leaking. By no means am I a mechanic or close to but I am trying to get this stuff done as cheap as possible so I am going to try to tackle this myself.
View 3 RepliesSo, weird smell that I thought was burning plastic or rubber is actually hot oil leaking from the valve cover and tensioner gaskets.
My car is nearly 8 years old (2003), and has about 70K. Should I go ahead and buy a timing belt kit and replace all that stuff at the same time?
I have a 2005 hyundai santa fe and the valve cover gaskets are leaking. We were able to change the one in the front but we cant figure out what to do with the back one. Need to find a video showing what to do...
View 2 RepliesOwn a 2000 Camry XLE 6-cyl. Both valve cover gaskets are leaking. Rear one leaks onto the manifold and causes stench. Have been quoted $350. to replace because the job is complicated. Have any of you done this on your own, and if so, would you recommend it or go to a qualified mechanic?
View 9 RepliesTruck 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?
View 19 RepliesSo I'll be taking on a project to replace the valve cover gasket on my 2002 Camry V6. There's a bit of leakage through the gasket. And while I'm at it, I'll replace the spark plugs as well. I'm looking for a write up on this project. did a lot of searching but couldn't find anything.
View 14 RepliesThe car: 1991 Honda Civic, 4 cyl manual Bought a month and a half ago. Past: I have been dealing with a slow coolant leak in the car that up to this point I have been unable to locate. No puddles or obvious leaks. Small amount of smoke out back, nothing like a blown head gasket, but a little more than average for a car its age.
~Ran a block tester - head gasket fine.
~Checked spark plugs - look fine, not too clean or dirty.
~There does also appear to be water in the oil from time to time, this is not constant, and I do not put water in my radiator (beyond mixing with coolant).
Today: Looking around valve cover noticed it was dirty. Also noticed some sort of sealant/caulking like material that easily came out of the seal between Valve cover and lower engine. I then began to drive the car and noticed small amount of steam coming from the hood. When I opened it up there obviously had been coolant spraying on the left side of the engine. It was difficult to locate a leak point, but appears to be coming from the seal between the valve cover and engine. I have seen it suggested else where that coolant could not leak from a bad valve gasket, but could be leaking from the intake manifold and look like it was coming from the valve cover. Should I just try to replace the intake manifold gaskets?
I have a 98 Subaru Legacy Outback with 133K miles. It was leaking from the power steering pump and valve cover gaskets. My husband replaced the passenger-side valve cover gasket (which involved removing the air box) and the power steering pump (which required removing the alternator). When we put the car back together and reconnected the battery, it no longer starts! It "clicks" once but won't turn-over. The car does not have an alarm system (but it was an option on this model). We've tried jumping it. The battery is about 14 months old. The alternator is about 10 months old and the starter was replaced about 10 months ago too. We've double checked the wires that were disconnected and don't think we've missed anything.

View 2 RepliesHow difficult is it to replace the valve cover gasket on a 2001 Santa Fe with a 2.7? Can I just do the 'front' valve cover? Are there any tutorials with plenty of pictures while doing this?
View 4 RepliesA few days ago I noticed some oil leaking from the left (front) valve cover area and I suspect it's the gasket. Fortunately, I didn't see any leaks from the back cover. It seemed like an easy job to replace the gasket, but as I started to disconnect the wiring, e.g., cam sensor, spark plugs, etc., I can't seem to find a way to remove the black plastic wiring harness 'housing' out of the way.

View 14 RepliesI did a valve cover gasket replacement. Changed all spark plugs and coilpacks. The car is still misfiring. I also just did the timing belt and water pump. Why it's still misfiring?? I'm new to this whole forum thing so bear with me lol. I'm wondering if it would be my cat, fuel pump, fuel filter. Or could it be a sensor?
View 2 RepliesA couple months ago I was hearing a hissing noise under the hood throwing the same code replaced the Valve cover, after there was no issues. Yesterday saw I had CEL and I was throwing P0174 code and there is a similar vacuum leak sound coming from under the hood but the Breather in the valve cover is not sucking in air. The Oil cap comes off but the engine starts to bog, what it could be now?

View 8 RepliesI have an 2008 Mercury Sable Premiere with a 148 miles on it. Just got the Valve Cover gasket replaced and new water pump put on. The car is running very smooth as it always done,but now when coming to a stop,it either acts like it wants to cut off or sometimes it just shuts off. When it cuts off I immediately crank it back up and it starts, but why or what could be the problem? It also starts up a little slower than before and I know its not the battery because that's brand new.
View 6 RepliesI noticed the oil smell that can be associated with a leaking Cam Tensioner Adjustor Seal from my 2003 1.8T Passat a few months ago. The dealer confirmed that it was leaking and that it was covered by my extended warranty since my car was 5 years old and at 70K miles. I had the work done and after I picked up the car I noticed that the oil level was at the top of the hashes not at the top bend like it was when I took it in.
I don't know what caused it to drop to the hashes but I do know that the level has dropped to 3 visible hashes in the little over 1K that has been put on the car since then. I am concerned because in it's first 70K miles the car did not visibly lose a drop of oil.
Any logical cause for this annoying trend, the only thing that changed was that the Cam Tensioner and Valve Cover Gaskets were replaced. Is it possible something else was messed up during the repair?
In order to replace the valve cover do the spark plugs have to be taken off ?
View 12 Replies5.4L 3v engine: The PCV is located in the drivers side valve cover. Tried to pull it out with no success and came to the conclusion that maybe it's threaded and a nut locks it in from the underside of the valve cover. Can this thing be replaced without taking off the valve cover?
View 4 RepliesI've got a 2004 Mazda 6 with the 3.0L V6 & a 5-speed, with about 128k miles.
The car runs fine, but was leaking oil onto the exhaust manifold and so I recently had the valve cover gaskets replaced. the mechanic could not get replacement gaskets from Mazda, and so changed the valve covers themselves also, and consequently needed to replace a couple of hoses that connect to the valve covers.
Since the repair, the car drives fine - acceleration seems normal, I don't notice any performance issues. The CEL is NOT lit.
1) When the car is in neutral, but rolling, the idle consistently bounces back and forth precisely between 1250 & 1500 rpm. This occurs always, and happens whether the gearshift is in neutral or the clutch is depressed. With the radio off I can hear the engine surging when this is going on. As soon as the car comes to a complete stop, the idle immediately drops to the a rock-steady position just below 1000 rpm, as it always has.
2) I assume related to the above, but since the repair my gas mileage has dropped from its usual 18-19mpg to 15.7-15.9mpg as recorded at two fill-ups, and my current tankful is looking to return equally low mileage.
I brought the car back to the shop and the mechanic took the car out for a drive with me, with his computer hooked up while we drove. He found nothing wrong, nothing out of whack, and saw no evidence of any air leaks.
1) Seems strange to me that the valve cover gasket couldn't be obtained, and new valve covers were needed. I want to believe the garage is being straight with me. Is this really plausible?
2) What could cause the idle to behave this way? I understand what a valve cover does (in my earlier years I changed the cylinder head on my old Saturn) and can't figure out how or why changing the valve covers would have an effect like this.
That leads me to conclude this is more likely caused by the new, slightly different hoses attached to the valve cover, but I don't know exactly what those hoses do or why they connect to the valve covers, so I'm stuck here.
