VF2 SSV Redline wagon
Hi,

Just wondering, is anyone having issues with noisy lifters on cold start with VF2 SS.

Our SSVR wagon is clatering when started cold, sounds like coming from left bank, done 35000 km's.

Probably get some crap response when i take it to dealer about it.

Cheers.

They're a noisy engine, so quite normal and will sound a lot louder if/when you do headers.

Leave overnight at dealer for cold start testing, also take a video as proof.

A change of oil type might help. Try Penrite 5w40 extra 10, GM approved. Since I changed to this and had my dealer use, my lifters have been noise compliant.

You may have noisey lifters. Or it may be normal. Remember though that aluminum alloy transmits sound very well. It also has less sound deadening abilities than cast iron.

Piston slap is another possibility?

My ls3 makes knocking/tapping noise under load when cold. Not while idling. Disappears after 5 min...
Car only done 7000ks
I'm not bothered for now..
Will report to the dealer if it gets worse...
