Hello,
A quick question to you sir: Jackson MS Honda dealer suggests replacing 2004 CRV engine with 125000 miles with code P0341+ with high oil consumption- 1 quart for 1000miles. Wants to get second opinion on engine change or just timing belt change+ tensioner. Any suggestions ?

 

125k is pretty disappointing as far as engine longevity goes!!

Ok, first, your CR-V has a timing chain, not a belt. That's important to know in this situation because a timing chain requires adequate engine oil levels for safe and proper operation. P0341 engine code refers to the crankshaft and camshaft being out of phase. Here's how this all ties together...the chain tensioner on this motor keeps tension on the chain guide using oil pressure. If the engine runs low on oil, the tensioner will apply less pressure on the chain guide, the chain will slacken, it will start to slap against the chain guides causing noise and wear, it may cause the cam to lag in phase behind where it's supposed to be based on the crankshaft's position, and if things get bad enough, it may even jump a tooth causing the vehicle to run horribly, if at all. The key here is I'm guessing your loss of oil is CAUSING the P0341 light, so replacing the timing chain/tensioner/guides will not fix the root of your issue unless you religiously keep on top of your oil level (which really you should do anyway).

1 quart per 1000 miles is right about the top of "allowable use" in most manufacturer's guide-books. It really is an egregious amount of oil use, but anything less than that and a company won't do warranty engine work for you. I realize you're out of warranty, but I say that to note that your oil use could be due to driving habits. Do you spend a lot of time in the higher RPM ranges? Do you do a lot of highway driving? Furthermore, do you notice oil smoke from the tailpipe? Do you notice it when you first start the car or when you're coasting towards a red light or stop sign? If you see dark smoke from your tail pipe you can be sure you're burning oil. When you see dark smoke can point you towards what part of the engine needs work, and it may not require a whole new engine.

 

Thank you Sir
This is the most comprehensive info I ever got. Am keeping the engine oil near max level for the past 6 months.
Engine swap is costing a good 4-5K. Most of the LKQ 2.4L K24A1 engines are more mileage than mine! Debating whether is it truly worth??
