| 2006 Toyota Camry 2AZFE Engine Rebuild Help | 16Relevance | 3 years ago | Shone200 | Submit Your Question HERE | |
| We have 06 Camry currently at 375k miles. Everything is good except it consumes a lot of oil. Those Camry's have a design flaw for thin piston rings. I poured the UV Dye and after driving it for couples miles, I thoroughly checked and couldn't find any leaks. So I know it's the piston rings for sure. I'm not planning on rebuilding the engine anytime soon , only for future reference when the engine eventually dies. So instead of just replacing the piston rings, I might well just rebuild the whole engine since I'm stripping the engine anyways and it takes a lot of time and work anyways to do it. We are a DIY and have never rebuild an engine before. I have been watching lot of YouTube videos and learning things on rebuilding 2AZFE Engine. So when I take the block to a Machine Shop will they let me know what size pistons and rings I need to buy after Boring and Honing Cylinders? Also will they let me know what size bearings I need to buy? Cause when I shop for pistons, rings and bearing its asking me what size I need. For example for the pistons and Ring sizes its asking STANDARD or OVERSIZE 0.50mm/0.020in. For the Main and Rod Bearings Size its asking me STANDARD , UNDERSIZE 0.25mm/0.010in or UNDERSIZE 0.50mm/0.020in. I am shopping for Complete Overhaul Engine Kit on Ebay or MagEngines.com. The kit on the dealer is way too expensive. Just for the rings alone they are asking $400. So I can can get a complete Overhaul engine kit on Ebay for $500 something. What does the Machine shop do to your blocks other than boring and honing? Do they do anything else? How much does it cost to Bore and Hone 4 cylinders? Also explaining to me in complete details from point A to point B helps a lot cause we have never rebuild an engine before. Thanks. | |||||

| Little gas residue always makes it past the piston rings. That is called blow-by. When it becomes an issue is when there's a lot of blow-by, and you don't let it basically burn off. Worn piston rings can cause this if your engine is already hot. It's inevitable that some residue will leak past the piston rings, it doesn't create a perfect seal. The engine can deal with ordinary blow-by, if you have a PCV valve, it recirculates back into the engine to be burned again. It's when it becomes excessive that you have a problem. For instance, smelling raw gas coming out of your tailpipe is way too much gas. | |||||
| Honda accord 2008 | 16Relevance | 3 years ago | 619mom | Submit Your Question HERE | |
| Hello I have a 2008 honda accord V6 2 dr automatic. 197k mileage, always had work done by the dealer.On10/2022 I had my car towed to the dealer for an engine light. The dealer got the following codes P3411,P3497,P0301.. they replaced all 6 spark, 2 gasket heads Replaced powersteering ra k Replaced oil pan gasket Now 2 weeks ago engine light turns on again, code P0301. Mechanic writes misfire cylinger 1 removed, spark plug found contaminated with oil. Recommend piston ring repair I was researching the 3 possible causes for spark plugs that have oil. 1. piston rings 2. Value steam seals 3. PVC system So to rule out if it is the piston ring issue. I need a leak down test to perform a relative compression check. to rule out if its a piston ring issue. In 10/2022 I had major service. All 6 spark plugs were replaced. I don't think they replaced the value seals, which they could have done when they changed all 6 spark plugs. Unsure what to do. My car looks great, excellent condition. I don't want to Sal age it. Is my motor gone. They changed out 1 spark plug and it runs. But I'm afraid it won't last. Help | |||||

| On what basis was it determined the piston rings are bad? Wet/dry compression test? Leakdown test? If the rings really are bad the engine is toast and would need to be overhauled or replaced. (A low-miles used engine from a wreck might be a solution in that case.) | |||||
| 2014 Honda Odyssey Piston Rings | 15Relevance | 3 years ago | agaskins3553 | Submit Your Question HERE | |
| I have a 2014 Honda Odyssey with ~115k miles. It's had an issue with shaking in low gears for a year or two. We had misfires last year and our mechanic replaced the spark plugs. Similar issue just came up: blinking Check Engine light, shaking in low gears, and no codes from the computer. We were told the engine needed to be replaced, which would exceed the value of the car. The reason cited was faulty piston rings. I have read that disabling the VCM is a potential solution. Are there any long-term solutions to salvage a reliable car, or should I just move on? | |||||
| Engine piston oil return holes clogged | 15Relevance | 4 years ago | Anthony31283 | Submit Your Question HERE | |
| I have a 2015 Toyota Camry se 2.4L it has 172,000 miles on it and the car is well maintained. Recently started buring oil i add 1 quart every 1,200 miles and toke it to the dealership and was told that it was buring oil because the Engine piston oil return holes are clogged and that it will take 6,000 dollars to repair. My Question to you is do i continue to add oil or is there a fix you could recommend to unclog theses holes and keep them clear because i don't have 6,000 dollars. Q. Is this a problem with 2.4L engines? | |||||

| Nothing will "seal" worn piston rings except replacement. Heavier oil might mitigate the effects somewhat, temporarily, but that can play havoc with the cam phasers in modern cars. | |||||

| Low-tension rings have been in use for over 20 years. You'll be hard pressed to find a modern car without them. Although such piston rings are by their nature more prone to causing oil burning and sludging those issues can be overcome with proper engine design. | |||||
| Answer to: How common are head bolt issues on 2002 camrys? | 16Relevance | 4 years ago | Jordandudgeon99 | Submit Your Question HERE | |
| Hey man happy new year! My search went very well. 1) I am the second owner. The first owner was an old man who took amazing care of this car, and had all the paperwork and records. Never missed an oil change every 3000 miles, and did the coolant and transmission on time. (The car currently only has 85,000 miles, (confirmed), and is in AMAZING shape!) 2) I actually Emailed Scotty Kilmer (yes it was his real Email that he states in all of his videos). I asked him about how common this head bolt issue is. He replied! He said he's never seen it once in his career, and doesn't believe it's common atall. 3) I made a reddit thread in a toyota mechanic group, and asked about it on a toyota mechanic Facebook page also (asking about how common the head bolt issue is). Every single toyota tech and mechanic who commented all said it was not very common at all. They say they've each seen one or two have the issue out of hundreds or thousands of the 2002-2004 2.4 camrys that they've seen. Some said they've never seen one with the issue! They all assured me that the issue is "common" in the sense that it's known, but that in reality, almost all 2002 2.4 Camrys they've seen in the shop have gone the distance (often over 300,000 miles!) AS long as they're taken care of. And like I said, I'm the second owner, with all the paperwork, so I know mine has been taken care of, and it will stay that way! They also said the ones that DID get the head bolt issue had one common feature - overheating or poor maintenance! (I'm sure that there are SOME that got it anyway, but that was the pattern they noticed).... was it a design flaw? Yes. Is trouble from it it totally avoidable? Absolutely! They encouraged me that the issue is nothing I should loose sleep over, and I have a very solid engine! Most never see the issue, out of all of the ones that were sold! "Carcomplaints" is helpful, but it's not conclusive - remember, people ONLY complain there. Nobody posts there when their car lasts forever! And most of these cars do just that! OF COURSE car complaints will have complaints! That's what it's for! But after talking to guys who have all worked on countless of this engine, the verdict is that it's a bulletproof engine, and the issue is RARE! (Toyota DID do a bulletin about it, but I'm told that their standards for when to issue one are very low, because they have integrity)!!! 4) The oil burning problem on the 2AZ engines did not start until 2007. This has been confirmed by multiple sources, including Scotty Kilmer on YouTube, many other Mechanics (like carcarenut), and all of the Toyota Techs who ive spoken to. Any before 2007 that burn oil, are likely burning oil because they didnt get their oil changed on time. They used better piston rings before 2007, especially in Japan! They did not switch their piston rings to the bad ones until 2006-2007ish. I own a 2002 made in Japan, that burns absolutely no oil atall! The inside of the engine is clean as a whistle. I'm on 3000 miles that ive driven since the last change, and my oil Is still gold and still on max. So I have no reason to be worried about oil burning! I'll just keep changing it at 3000 miles with synthetic oil! (Toyota actually did a recall list on the piston ring issue - my car isn't on it. None before 2006 are! Because they didnt have the bad rings!) 5) my transmission is smooth as butter. Scotty Kilmer has a video on YouTube with this exact car, same engine, calling it "one of the best, most reliable 4 door sedans ever produced". In that video, he gives some specific praise to the transmission, saying he's seen them with 500,000 Miles, still on the original transmission. I've done lots of research on this transmission, and have spoken to lots of toyota Mechanics about it now. If the fluid is done on time, and you dont bag your car, these transmissions last! Especially in the 4 cylinder! They're very reliable. SO.... THE "STATS" ARE GOING GREAT!!! (I was never looking for stats, but like I said - just a bit of info from the RIGHT guys.. and I got it!) I have been very encouraged by my findings. I have learned that the 2AZFE is a very misunderstood engine, with the issues spread out over the years getting all clumped together as if all these engines had all the issues. In reality, my car is not prone to oil burning, as it has good rings in the year it was made, and the head bolt issue is extremely rare, and usually only happens with an over heat. This car is in top shape, and has not been overheated. I never plan to overheat it. I'm going to he preventative, so I have a thermostat, Rafiator, and water pump on the mail (all OEM).... I am so very glad I did my research, and I am very glad with my choice of car. Can't wait to drive ot for many more miles to come!!! Woo-hoo!!!!! | |||||

| RE: piston slap and oil viscosity - 2002 Mustang GT | 15Relevance | 5 years ago | theeel | Submit Your Question HERE | |
| Because the thread began with a long winded explanation of why the 4.6L should be using 5W30 like it did originally but Ford changed it to 5W20 to meet CAFE standards. It was mentioned in the thread that the oil change resulted in a minuscule savings in gasoline (less than 1%) but results in much less protection of the engine (about 30% less). People would rather their engine last longer so a lot of Mustang owners went to 5W30 while a few complained of piston slap. | |||||
