accord 2003 2.4 rough idle after oil change

Well here is the story. I believe it was the day before the oil change was done that the car died once or twice.
It started up again no problem though.
The car was low on oil. Not my car though.

The original engine was replaced because of similar symptoms and the mechs determined the engine should be replaced. That engine had 180 clicks. The engine now has under 100.

Anyways after the oil change the car doesnt start anymore unless the gas is pressed. It dies if the gas is let go and chokes under 1200rpms. Above this the car drives fine.
I had to drive it 25 kms to the house by keeping my foot on the gas pedal and going back and forth between neutral and drive.

ODB codes revealed P0341 Along with a series of 0300
Reading a lot on these forums a compression check
The car wasnt warmed up though.

Cylinder 1 Dry 140 Wet 240
Cylinder 2 Dry 240 Wet 270
Cylinder 3 Dry 240 wet 270
Cylinder 4 Dry 240 Wet 280

Is the compression looking too high?
Can anyone with experience on this please provide input?
What should be done next.
I really hope its not another whole engine rebuild.

Im going to try a leak test to isolate further.

Thanks for your time.

accord 2003 2.4 rough idle after oil change

Hi,

After doing another dry compression check this morning, cylinder 1 is at 220 and the others stayed the same as before.
Not sure why the variance unless I was doing something wrong.

I opened up the head cover and Ill try to post a pic.
The camshaft sprocket is behind 2-3 teeth when the VTC is TDC. The dash mark is behind as well.

This doesnt look too good right?
Would it cause bent valves or can I rotate and align manually by lifting the chain? Or would I need to change the cam chain and auto tensioner?

Hi, thanks for the link. Dont think my cam is damaged but regarding the chain and how many teeth it skipped I have posted a pic.

Can it really skip so many teeth, there is no room for the chain go anywhere, there is some slack but not enough i think? Is there any way I can raise the chain and align it myself if the valves are not bent?

I'll pm Fredsvt to see what he thinks. He works on these cars for a living and is very good at it.

Hi, Thanks much appreciated. Ive actually read a lot of Fredsvt's posts and communicated with him briefly about this.
Im checking these forums every few hours throughout the day as I really want to avoid another engine. Ill get more pics if need be.

I got to work on this but was only able to work on the weekend. Few weeks have passed and things that got in the way are the crankshaft bolt, as an impact gun didnt help and waiting for the tensioner and the chain to arrive.. due to budget that all weve ordered.

Anyways, all was taken out and confirmed the chain was slightly stretched compared to the new one. And the tensioner was bad, damage on the teeth, retracted all the way.. etc.

New parts put in, along with new spark plugs, engine starts! hurray.

Now the only issue is, it idles at 3k rpms on Park\Neutral. Drops to around 1k when in drive or reverse.

Is this due to improper idle learn\ckp learn.
Can I avoid the HDS tool to do this?

Big thanks to Fresvt btw.
