I have a honda accord 08 with 70 miles the car makes a noise only on cold start i don't know what cause this noise but I think its not normal. I would like to know if somebody knows about this problem. Thanks

GoLowDrew

Like what? Describe the noise. More info. Maybe a video?

MSchu

@ 70 miles you should be worried...

post or describe please.

0Steve@Spreen

Probably 70k.... V-6? If the noise goes away when the vehicle warms up...probably the return hose o-ring on the power steering pump. Pt # 91345-RDA-A01. Easy fix. Other than that, like previous stated, more info needed.

My guess is that its a 4 cylinder. If so what you are hearing is the VTC actuator. It will need to be replaced. Look at Service bulletine 09-010.

X2 ^......but some of the v6 had a sim issue.

tech8

V6 didn't have VTC -Variable Valve Timing Control; so, it would not be a similar issue for a V6.

Lost Again

The v6 do have vtec but then they also have VCM....or am I getting my 07 Pilot confused with the Accord......could be

MSchu

you're both somewhat not completely correct. the 6 speeds had NO VCM and DID have vtec.

tech8

VTC is not exactly the same as VTEC.

On Honda’s K series (4 cylinder engines), i-VTEC system adds VTC (Variable Timing Control) to VTEC to provide continuously variable camshaft timing . It is a different concept of variable valve timing. For the K series, i-VTEC is a combination of VTEC and VTC.
i-VTEC is intelligent-VTEC.

VTC and VCM are different animals.

While the 8th generation Accord V6 (J series engine) had what Honda terms i-VTEC (intelligent-VTEC), it does not have VTC. Certain 8th generation Accord V6 had i-VTEC with VCM. VCM is Variable Cylinder Management. Depending on the driving conditions, the Accord V6 can go from 6 cylinders, to 4 or 3 cylinders for fuel economy.

tech8

I did not state the V6 didn't have vtec.

k3lvin_08

my car is a "4 cylinder engines" but I am not sure what i have to fix because I have seen different comments.

in this link you guys can see how is the noise.

My car used to make the same sound Steve@Spreen mentioned above. It was a V6 as well. The noise used to be so loud that you could hear it in the room above the garage. After 10 miles when the car warmed up the rattling was gone. The noise disappeared completely even on a cold start when the warranty recall of power steering hose was done.

MSchu

you DID say the v6 had VCM... that is not entirely true.

that sound is almost like the engine is Dieseling just after start up OP... like the plugs are pre igniting the mixture. what did the dealer say?

HatchVX

That is is the VTC actuator. Im a honda tech and have done MANY of these.

0Steve@Spreen

He stated it correctly, certain V6s do have VCM, he didn't say all

OP, I believe HatchVX is correct, we have replaced a few of these here as well.

MSchu

are you sure... I am.

the original statement stands... both those knuckleheads were not ENTIRELY correct.

tech8

Re-read my posts, I never stated all V6 had VCM, I stated certain V6, which Steve@Spreen pointed out. You're the knucklehead here regarding my posts.

tech8

You've been misstating things in several of your posts.

0Steve@Spreen

Getting a little OT here guys....MSchu, both posts never stated "all" Tech 8 said certain, and Lost Again hedged his comment stating that he was speaking from his personal experience with his Pilot.

Guys play nice, don't make me pull this car over

K3lvin_08, any progress?

BLKFLSH

So do any of you Einstein's know how to fix the actuators? How difficult is it? I don't think the OP gives a crap what V6 engines have VCM.

tech8

It may have already been posted before on this forum.

Here is Honda TSB A09-010 and a related Honda Tech2Tech video. I zipped the TSB as it wouldn't upload the latest pdf.

BLKFLSH

That looks like fun. I didn't notice any special tools, besides needing an air compressor for one part. I guess you could do it yourself.

HatchVX

Follow this video http://cms.skunk2.com/id/377/
It helps with the swap.

k3lvin_08

I have been reading your comments and I think the way for to fix that is replacing the VTC actuator...
