hi guys

My h22 lude recently developed whining noise and there is a loss of power specially at low end. Sometimes it runs perfect, vtec kicks in no problems and sometimes it losses power and vtec very weak.

Any ideas

 

whats your maintenance history? :

when you have replaced your ignition components?
cleaned valves (egr and so on)?
last time adjusted valves, changed air & fuel filters.....?

 

first check for codes, might need a tuneup.....spark plugs, cap, rotor

 

I just replaced the cap and rotor last weak because the car wasn't starting. Spark plugs and fuel filter almost a year. Checked for codes nothing. Valves adjusted few months back

 

- air filter and spark plug wires
- clean injectors/iacv/egr/fitv
- check does sensors work properly: map, iat and tps (and try calibrating tps), o2 sensors
- clogged cat might you give some trouble as well (usually when driving) - check cats condition
- check throttle cable (tight enough)

 

Egr is blocked, iacv cleaned two months back, fitv blocked. I run straight pipe no cat. I will check the sensors and injectors. The throttle cable is little lose I will tighten it and see what happens

 

post vid plz

 

Will do. I just saw a cut in pcv valve hose and the hole was blocked with black **** lol. And oil is dripping in the exhaust. I will replace the hose and see from where the oil is dripping first.

Video of oil leak

 

Could be the auto tensioner failing or one of the bearings failing or gone bad. I would probably do a timing belt kit if you narrow it down to the timing side.

 

when was last timing belt job done?

If auto tensioner would be failed, you probably would have bent valves and a lot more problems than now

 

Timing replaced around 7 months back.I pulled the valve cover but the belt looks in place and the marks on the camshaft are matched. How do I know that the tensioner has failed? The oil leak on the driver side I think because of the cam seals? And the middle maybe from the oil cooler seal? The whining noise comes only while accelerating.

 

does it tighten the belt? :D

 

The belt is tight enough 👍🏻

 

I just found out the leak source. I think it is the oil sensor not the oil cooler o ring

 

My timing belt made the car sound like it had a super charger when the belt was too tight. You should have some play in the belt, as in you should be able to push it with your finger and it should bend.

Balancer belt? Maybe its an issue with your balance shaft? Are you still running a balance belt?

You can check the distributor for OIL, maybe the bearing in the dist is going bad.

 

Usually they make a distinct bearing noise but

Check with an automotive stethoscope,$5 off ebay or a garden hose,to find where the whine is coming from.Not easy to pin point sometimes.

 

Just to let you know guys problem solved. It was the oil pressure sensor leaking a lot and making the oil pressure drops. I had it replaced and now no more leaks no more whining noise 😁

 

hope you got oem sensor there - I have bad experiences about sparepart sensors (other than o2)

 

Yep I bought OEM. I was like that buying cheap stuff but I learned my lessons After I had it nicely lol 😂
