Engine knock?

Jayjjcc · 07-27-2010, 10:21 PM

So my '05 CVPI has a nice little knock knock going on... a friend that used to be chief mechanic at a Ford dealership says it sounds like sticky lifters... suggested I put in a can of Wynns engine tune-up in the crankcase, after 500miles, it wasn't helping, so he told me to add another (325ml can I think is the size)... it's still hasn't helped...

My first question is: should I change my oil ASAP? Some people told me that it can burn the seals/gaskets?

Second: the fuck do I do now?... how do you clean sticky lifters?

check the timing chains.

You cant fix a mechanical problem with oil

If its real bad you'll need to take it apart.

The 4.6 isn't known for valve noise issues. If it's a bottom end knock, the knock should change sound on quick RPM change.. see if it does by blipping the throttle.

it gets faster and higher pitched with throttle

then your fucked.

get AAA now... your gonna need it.

higher pitched?

how many miles are on the car? my money is on the timing chain, as Fordinator stated but without more info or possibly a video or sound clip its hard to tell.

^^^ there's one on every board...hahahahhahaha

car doesn't seem like it gonna die on me tomorrow... I might need AA more than AAA at this point...

I'll get a video/sound clip tomorrow (I drove 600km today so I can't get a nice cold engine noise clip).

My other question would be: how much $$?

I was told noisy lifters could be removed and cleaned? Timing chain tensioner/timing chain/gear would set me back approx.?

The other thing is: could I clean/change this myself? I'm not a mechanic, but I'm not an idiot either... I've changed my own tie-rod ends, brakes, rotors, oil, water pump, fuel filter, shifter cable, cleaned out carbs, etc without having to cry about how hard it's gonna be while I watch youtube videos on how-to do it... I've also got a buddy who used to be head mechanic at a Ford dealership (although I ask for his assistance as little as possible since he has major health issues)...
