hi all from the uk names Paul ,bought my camaro about 5 weeks ago still waiting for our dvla department to give me a registration and title number so cant actually use it legaly on the roads .the car has developed a noise from the engine it sounds like something loose may be a rocker or camshaft follower what normaly wears on these engines dont know a lot about them ,give it a fresh oil and filter

 

Hi Paul,first off we'll need to know what year car and what motor it has and what the mileage is on the car and the motor if known.
Lifters(followers) are a common place for noise especially in a tired engine,most are hydraulic and once adjusted should last until worn out.
Some (few ) high performance engines in the early years had solid lifters which are naturally noisy even when adjusted correctly and get really noisy when out of adjustment.
A broken valve spring could also cause cam train noise and if the valve lets loose destroy your engine so I'd recommend not running it anymore until you find the source of the noise.

 

hi there thanks for getting back to me its a 2011 camaro with 105000 miles i think its a ls model not up on these cars yet will make a video of it and try to post it ,will be in America in 4 weeks on holiday so be shopping for parts wheres the best place to get parts that will have them over the counter going to las vegas and newport beach california thanks Paul

 

Welcome to the club.
Once engine reaches operating temp, still makes noise?

 

makes a noise from cold gets louder as gets warmer when you rev ait to about 2500 rpm its noisey sound like its coming from left hand side of engine.do cam lifters wear out or cam bearings?

 

rocker covers off and have a look i think new to these v6 engines should be fun

 

I do not own one so I have never researched it but valve train issues are very common on the V6. If you google it you will get a lot of hits including youtube videos.

 

Timing chain stretch/failure is common on the 3.6 engine you have, especially if previous owners were abusive with infrequent oil changes or letting the oil level run low. And/or if the engine is sludged up, the timing chain tensioner could be compromised and not keeping the chains tight (another contributor to chain wear). If you're hearing a metal on metal slapping type of noise, then that's most likely what you have going on.

 

Hello
I have a 95 3.4 camaro

replaced my flat tappet lifters
Ran the car at higher rpm with assembly lube for 20 mins for break in everything seemed good till I started to drive the car 30 mins later ran it all 5 gears up to 60mph
Car ran good and then I felt it start to bog also developed a ticking noise

it got worse and worse 1st gear fully flooring it barely drives almost stalling but doesn't stall just barely stays running
because the engine is running poorly

engine feels like it's hard to turn over at start up

I know this has to be something with the lifters because I pulled them out 3 diffrent times
And reassembled everything and all 3 times the car runs great for about the
same amount of time and starts to fail the same way.

when I pull out the lifters the plungers are alway locked up and I always bled them
Made sure plungers works good before putting them back could this be some issue with the lifters locking up or maybe antifreeze getting in through
Where the heads connect to the bottom intake?


All I do is bleed the lifters and the car runs
Good for a little over half an hour then fails the same way and never gets better till I bleed the lifters again

I don't want to do this for the 4th time knowing it's going to do the same thing has anybody had anything simular to this
Please let me know thanks
