I was changing my mom's oil at work today. I noticed her timing chain cover is leaking. Is this just an isolated occurrence? It seems to be right where the FIPG mates the timing cover to the cylinder head. It also seems right below the tensioner. However the tensioner is bone dry.
View 9 RepliesGot an oil change yesterday and the dealer noticed a small oil leak from the timing cover on my '10 Corolla w/ 71k. Of course they could reseal it for $450. After further investigation, it looks like it is actually coming from the timing chain tensioner. I have seen on the 9th gen this is a common issue, but I haven't really seen anything on the 10th gen. Sometimes, I have noticed a short squeal or squall at cold startup, but it hasn't been enough to really diagnose. It could be some oil on the belt or something else related to this issue. Hopefully the pictures show up.... [URL] ......

View 10 RepliesI have seen this minor oil leak on the left engine side that facing the firewall for sometimes, but just found time to bring to dealer. After some searching on Internet, I suggested to them that it might be leaking from the timing chain cover.
View 19 RepliesMy truck has had this annoying tendency to drink coolant. I believe I took care of it by replacing the thermostat gasket. Not so, it drinks about a quart every 50 miles - so quite a bit really.
Finally bit the bullet and took it to the dealer so that they could figure out where the coolant was going.
Answer I got back was - timing cover gasket, water pump, lower radiator hose.
The water pump appears to be good, its just the gasket that's bad. So my question is - how significant is the timing chain cover leak? Poking around online it appears to be reasonably common, but sounds very expensive. The dealer indicated it would be 2 days work minimum.
My 2003' Explorer XLT (4.0L V6) has an oil leak. I tracked it down to the passenger side, rear, bolt head on the valve cover (back by firewall). I took it to a guy who replaced the valve cover gaskets, but it is still leaking. He claimed when he had the cover off he looked for any cracks on it, but did not see any at the time.
Anyways, I was searching around and found several explorers leaking in or around the same area of the valve cover. And it turned out that there issue stemmed from bad timing chain guides, causing the valve cover to crack.
I do notice that on a cold start, I hear a rattling when I first start it up. It rattles for maybe that first 1-2 seconds when starting. Is this my timing chain rattling around? If that is the case, how much this could set a guy back on repairs?
I guess I don't know whether to just replace the valve cover, or if I should dig into it to see if the real issue is the timing chain guides/tensioner. Mileage is approximately 121,000....
I have 2000 V6 3.0 Ranger and it has sprung a small coolant leak from timing chain cover gasket. I think just few drips after driving a while since I don't see significant drop in coolant level (Took a month to notice level dropped in reservoir) and did not see an active leak while idling. No water in the oil.
The proper repair would be to replace the gasket, but for the age and condition of the truck, I don't think it is worth it. Searching for a cheaper solution, I found K-Seal and see lots of reviews with success. Will it damage the cooling system in anyway? I think it would be worth a try even if it doesn't fix the leak as long as it does not cause any harm.
OK... I know next to nothing about cars. I have a '99 Chevy Lumina I just bought in February. It has been one problem after another. The water pump has been changed and I just got my car back on Monday because there was a leak on the timing chain cover. Now, the car is smoking on the passenger side. Its not a light smoke, but its not heavy yet. I noticed it on the way to work this morning. I opened the hood, it is coming from the left side (looking at it, so the passenger side) of the engine maybe kinda underneath it. I dunno what to do, but I'm ready to push that thing into a lake.
View 1 RepliesI went in today for a factor recall on my 2006 Toyota Corolla and when I was leaving I was told that my car needs to have the timing cover resealed. Additionally, the Drive belt is cracked and it was recommended to me to get a new belt. My air filter is dirty, I need manual transmission service, Fuel injection service, Fuel induction service and an AC refresh.
Being a college student I wanted to get some feedback on some of the stuff I could do myself. I already change my own motor oil and oil filter and anything I could do myself from the above recommendations from Toyota would really lower the cost.
Also I am not really sure about the timing cover reseal because I have not seen any leaks under my car. It may be that I do not understand what a timing cover leak is. And is this something that I should get fixed right away or can i afford to wait for a while (1 year or longer).
Also what is the difference between a fuel induction service and fuel injection service? Can i do it myself?
We got a 15 F150 yay for her but I got stuck with her 113k.
So the engine makes a chain grinding sound on cold start ups and the tranny is slipping pretty hard.
Can I swap a 2.4 with a 5spd without doing a bunch of wiring?
My 2007 3.3l SF timing chain cover is leaking.It has 93,000Kms and is still covered by warranty.The Dealer said it was a 17hr break down job to do.
I am wondering if there are things I should get done/replaced when they open the engine up. I had asked at the dealer if there were other parts that should be replaced at this time, but was told that there was not.
I have a 2011 Limited and I wanted to mention that I brought it in for the ECM service campaign and to have an oil leak looked at. The reflashing went as expected, I am still trying to decide if the car behaves any different. It seems like the engine RPM drops a little bit when slowing down then bounces back up. Nowhere near enough to stall or anything.
While I had it in the shop, I had them look at an oil leak that I have been having. According to the dealer, it is leaking from the timing chain cover. They have ordered some parts and I will be taking it in for the fix next week. I don't have a full list of which parts they will be replacing, but he did mention removing the valve covers and installing a new oil pressure switch while they were in there.
My 2010 Santa Fe is leaking oil. I bought it in April & it has under 8,000 miles. After parking the car, I see oil spots that range in size from a Silver Dollar to a CD after a few hours.
First, the dealer said it was a cracked oil filter cap, so they replaced that...I brought it home and it was still leaking.
Brought it back to the dealer, and now they are saying the Timing Chain Cover Seal is leaking.
My daughter just bought a 2002 Santa Fe LX which is drooling oil all over the alternator and everything else in that area. I found what (I think) is the source (but you have to be a contortionist to see it.) I haven't been able to find any good parts identification photos of that area, but I think that this is the bottom corner of the lower timing belt cover.
I guess the repair will require going through the first several steps used when replacing a timing belt. I don't plan on going any further than needed to fix this leak, though, since the timing belt was reportedly changed about 25K miles ago.
Before I start taking all this apart, I have a couple questions:
1. What might be holding this corner out, away from the block?
2. Is the timing belt cover supposed to snap into place over a lip on the block? Or, should it be sealed with gasket sealer -- or something similar?
So I just traded my old car in for this one and I've had it maybe a little over a month. Anyways, when I go to start it now, even if I just turn on the main power and let the radio start up and the computer and then turn the engine. When it turns, majority of the time it will "squeal" like there something might be going wrong with a belt in there. I know that the timing belt should be changed once every so many miles, just not so sure on my vehicle. Also, if it could be anything else besides that.
View 1 RepliesI 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.
View 11 RepliesI 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.
I have a 2003 Eddie Bauer explorer with the 4.0L SOHC . I have a coolant leak from the passenger side that is not a water pump issue.
When removing the timing chain cover with the engine in the car, do I need to remove any accessories ( power steering , alternator etc. ) or their brackets?
I had the front timing chain cover replaced, ever since it hasn't started. It would turn over fast a couple times and then drag and then repeat.
Found out the "Tone ring" was warped, it's been replaced and now it just turns over and over and no start but it doesn't drag anymore.
We can smell the fuel, and pulled a plug and can see spark while turning over and I was told fuel came out the plug hole so there is fuel there.
Tried a new cam sensor, crank sensor and battery and no change. Is there something else in the removal and replacement of the front timing chain cover that could be causing this?
I'm not a huge believer in coincidence as the vehicle was running great before this job.

On Feb 2015 I had this oil leak developing around the timing chain cover/ oil pressure plug and so i replaced the oil pressure sensor and clean the area and though problem solved...
Fast forward today and the weeping has redeveloped and has gotten larger than last time , its only a weeping issue no visible oil droplet leaks, anyways I took a mirror and when probing around and found the leak origin from the rusty looking timing chain tensioner...that what i think it is.
My question is should I just remove and replace the Rubber O-ring on it or should I just replace the entire timing tensioner unit with a new one, my original timing chain tensioner is sitting at 85k miles. The O-ring is free (i have a kit) and i can do it right now or a New Timing chain tensioner w/ new O-ring is around $20 bucks but i cannot verify the part number ...
I recently bought a 98 CE with about 80k miles for my commuter car. Overall I am very please with it but today I started hearing a metallic type chattering sound from the left side of the engine (looking from the front). Sounds to me like the timing chain is slightly loose and maybe the cause of the sound but when I search all the auto pats websites it doesn't show a timing chain tensioner. So do I have a belt or a chain? What the sound is? it doesn't do it continuously but it does seem to only start when the engine is warmed up and at idle. I did a compression test and all the cylinders are in the ballpark so Im hoping that's means my valves aren't taping.I cant imagine it would have lasted this long if the valves were taping (driven it about 500 miles so far).
