Re: Top end clatter / lifter tick?
 

I've had a very similar thing happen where I have a loud tick when motor is cold and it starts to dissipate as engine warms up until it disappears. Typically it shows up on the passenger side for some unknown reason.

Re: Top end clatter / lifter tick?
 

I am surprised more of you guys do not have some piston slap noise on those cold mornings.
I think I have just a bit of piston slap on a 1990 LT5 which goes away quickly as engine warms up.
I have had piston slap on a Toyota 4x4 for the last 200,000 miles :D

Cliff,

As I had posted earlier, I don"t start my car in the winter unless temps are above freezing and preferably >40F. Looks like may I may have a chance to do that later this week.

Re: Top end clatter / lifter tick?
 

I don't start my cars through the winter. Just kills the oil in my opinion. I check the oil in my vw (07 Passat wagon with a oil guzzling 2.0t) every few days and there is ice buildup every time on my dipstick tube and oil cap because of the cold and moisture/freezing every day. Ill post a vid later tonight.

Anyone know if the lifters are from a different manufacturer on the later year engines?

Sounds like the right side chain tensioner has locked up.

Take the tensioner out if it does not come apart it's stuck,you will need new tensioner.

Since it's right side it's somewhat easy to check/take out.

Colin,

I made a couple of videos of my engine noise and how it stops if I push down on the belt tensioner or turn off the air conditioner. If you give me your email address, I can send them to you.

Or if someone else can post the videos, I can email them the videos. That way others can listen an see if it sounds like the same problem.

They are large files so I don't know if that's a problem for email.

Let me also add could be broken chain guide.
If chain guide broke/bad i would not run it anymore, have it checked,take valve/cam cover off, with the cover off you'll be able to check guides and chain tensioner i will tell you how once you have cover off.

That is not lifter tick/noise last time i heard noise like that it was tensioner locked up does not happen often.

Re: Top end clatter / lifter tick?
 

I was thinking chain/chain guide possible issue also but then Jerry counted 400/min.....which each side has different chain length and if chain had issues or guide would not be 400/min. Only 26K mile engine also suggests chain guides would be hardly worn in.

Just seems like lifter/valve issue.

Compression Check.....
Remove Serpentine Belt eliminating all other front end possibilities excluding Chain/Chain Guides.
Then Cam Cover removal like Pete suggests and with Pete's help in that diagnosis to check Timing Chain/Chain Guides as well as Lifters, Valves.

Re: Top end clatter / lifter tick?
 

I don't know the history of the car but if the cam covers were removed for powder coating they had to remove chain guide
Maybe they hurt the chain guide.
I'm just going by the sound.
I also considered water pump but he is saying sound is coming from #2 cylinder
And sounds like it is.
