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?
Replacing the timing chains and tensioners on an SOHC Explorer, only to have the tensioners fail again after only a few thousand miles? I'm a pretty experienced back yard mechanic and have rebuilt several engines over the years with great results, but this one has me stumped. The only part of the instructions I did not do was to remove the valve springs, but everything was lined up as it should have been using the special tools required to set the timing. I really like the truck, but don't know if it's worth fixing if this is just going to happen again.
View 3 RepliesMy 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.
There was a time Ford when used a nylon toothed timing chain gear on the camshaft. Over time this got brittle and started to break into pieces. The rule of thumb at our household was to change these at about 100k miles.
I think that was a "302" thing and all "5.0" engines have all metal gears? I have no reason to open up our '99 Explorer's 5.0 with 180,000 miles. But, I will change the timing chain if it should be done.
My 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.
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.

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 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 RepliesI 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?
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 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 have a 2005 Ford Explorer with a 4.0 SOHC while the engine is running the left side timing chain rattles. I replaced the timing chain and guides and tensioner, the engine has good oil pressure but the noise is still there.
View 2 RepliesHad 2 valve cover gaskets fixed 2 times on this car. Now I have a timing cover gasket gone. This is real big $$$. Dealer quoted a price of 1400.00 . Contacted Hyundai of America and trying to get some " good will" . It's the 3.3 V6. I know this engine seems to have these problems . This car has 127,000 miles.
View 2 RepliesOK... 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 RepliesSo I was installing my head spacer. When i got the head off I noticed the upper two timing chain rails were shot. The tensioner rail has wear marks from the chain and a small crack in it. Is it possible to change these upper two rails without dropping the transmission?
View 5 RepliesWas told my Sonata has a leak at the Timing Cover Gasket by two different service stations. Took it to the Hyundai Dealership and they said they would need to pull the engine out to fix it and it would take a couple of days. I read on a couple of other posts that people were able to replace the timing cover gasket themselves. So, I don't understand why the Dealership said the engine would need to be pulled, but I'm reading others say they fixed it without pulling the engine. Am I missing something...? I'd rather not have the engine pulled out if it doesn't need to be.

OK, my truck is making all kinds of horrible noises from the timing chain area. it is a 97 f150, 4wd with a 4.6. i know i need to replace it. BUT my question is, how long can i let it go before the chain breaks and sends valves into piston? And also what is the best timing set manufacturer? or are they all pretty good?
View 4 RepliesI have a 4.2 with 330km (206k miles). Recently I have noticed some unfamiliar sounds that I'm trying to diagnose. First off, lately when starting the truck cold, it sometimes makes a metallic screech /clank-like noise. It just lasts for a moment when the engine catches, then disappears. Doesn't happen every time but has happened at least 1/2 dozen times the last couple of weeks. Sounds like metal gears colliding. Haven't noticed any drive-ability issues.
As well, I changed the oil a couple of days ago and when I stuck my head under the truck afterwards to check for leaks, I could hear a definite rattling / clattering noise from the area near the oil filter.
Does this sound like timing chain?
