Type r ep3 engine warning light
Discussion
Just picked up ep3, eveything is running fine, slight tapping noise coming from engine at idle but sounds normal would say im being paranoid. Exhaust has recently been changed from a decat to and aftermarket but more standard exhaust with a cat in it. Could this be the cause, did not throw light on test drive even though the test drive was longer than the distance i have driven. Please help, many thanks.
Did you buy the car that you found to be running low on oil?

Should have used a code reader before buying. I always take mine with me. £5 from eBay and app was £5 which lets me clear codes. Probably the best investment for a modern car, helped me out loads.
Always ask the seller if I can check for codes, if they say no walk away. Sometimes codes don’t throw an engine light straight away but the reader would still find if anything is in the system.

Were the oxygen sensors connected up correctly when the new exhaust and cat was fitted?
Elderly EP3s, particularly ones that are run low on oil and/or don't receive regular services are prone to timing chain wear. The ECU can detect the change in timing between crank and cam that this causes and will set an error code when it exceeds some limit.
Obviously you'll need to get the code read to determine the actual cause though.

Scrap it.
Why bother posting that?Op do you know if the car ever had a Hondata KPro or K100 ECU fitted? Normally when the cars are decatted they require mapping to correct the fuelling as k20engines run a bit rich as standard. Another alternative is look under the car to see if the lambda sensors are screwed directly into the manifold or if the lambdas have 90° spacers installed as this is a trick to fool a standard ecu into thinking lambda readings are lower.
Download torque lite and buy a em377 Bluetooth adapter and you can extract the error codes plus reset them.
I'd also do a oil an filter change asap, run the car a few weeks an do another oil/filter change for peace of mind. Always check the level,keep it on max!!!if you use HAMP honda performance filters these will increase oil pressure a little to if you are worried . The ticking noise can be the cam chain tensioner or sometimes the idle valve can make odd noises to
Get it read on an OBD scanner but if it’s decatted without a map or a lambda spacer it probably has chucked on the EML.
The tapping is probably valve clearances. They should be done every 25k if I remember correctly.
If it’s something more sinister behind the EML then good luck. I was once told they can jump 1 tooth on the timing chain and you wouldn’t know, 2 teeth and the EML comes on and they run like s
t. 3 teeth and it starts smashing valves. Timing chain & tensioners they recommend doing at 100k. Not that expensive or tricky a job and certainly worthwhile doing if you’re going to keep it.

In which part of the system does it increase oil pressure?If you've done testing to verify oil pressure changes/flow rates with an array of different oil filters on a K20 engine I'm more than keen to learn. All I'm going on is the advice from guys who have built/run cars in various Honda championships & those who track their cars combined with the filters being no more expensive than a standard Honda item.
I've done nearly 30k in my Type R , i did 2 oil/filter changes using standard Hondas items when I first got the car, then 5-6k changes with HAMP filters ever since. My engine hasn't gone bang, doesn't make ominous tapping noises so I assume all is well.
Happy to be corrected.

It still sounds flawed imo
There will be some pressure drop across the oil filter. A less restrictive filter would have less pressure drop. That means the engine will see more pressure. I have no idea whether it's enough to matter, but there's nothing fundamentally wrong with the idea.fiju said:
The bit that sounds fishy is that it somehow maintains the same level of filtration yet there's an increase in oil pressure.
I could design a filter that gave poor filtering and produced a big pressure drop. I don't see why somebody with more care and willing to spend more on materials couldn't do the opposite.AA cane out and it was to do with the catylic converter, was fine the whole way back down the motorway and fine yesterday but this morning it pinged back up again. Going to take it in for a timing chain and a service and more thorough check over for rust etc so hopefully the issue can be resolved easily, thanks for the help.
