Whats that knocking?

[NoDoz]

So I just saw a VW Beetle turbo pass and it had this knocking sound in the engine. It seems that every car that ive come across latley with a forced induction engine has this same noise (im talking about non-enthusiast daily drivers). What is the noise? and Is this because of poor matainance on the owners part?

Probably people who don't change their oil often...

causing nasty lifter noise

[Murderface]

But loud enough to be heard as it's driving by? I agree our lifters are pretty loud especially on a cold start but still.

[Cincy]

When my engine was put back together, the lifters were all you could hear. it took about 1k+ miles of driving for them to quite down. Both the lifters and cam tensioner could make enough noise that a stocked exhaust car passing by you could hear them.

[Murderface]

Wow...when I fired mine up, I shat a brick as I heard what sounded like all four lifters playing marbles at 700 RPM...then realized the engine I just fired up had been sitting for at least 3 months. Pretty quickly (few mins), as they got oil, the lifters shut up and returned back to typical ticky VW head noise levels.

[Cincy]

Yep, the guy that put my engine back together wanted to replace a bunch of stuff and cost me another $2k, i was like nope. Now my engine is back to normal except a tiny bit louder overall

It was very nasty http://i192.photobucket.com/albums/z25/ashhh_012/ormout.gif

[NoDoz]

So this is something that happens over time?

[Cincy]

It shouldnt unless the car is poorly maintaned. Of course the tensioner can slowly go as the years and miles add up but its nothing like a TB issue

[NoDoz]

I see

Holy crap, that sounds diesel :blink:

Did you get anything in your head replaced? Mine was just clacky sounding for a minute or two when it first fired up...after that it was normal.

[Cincy]

nope, mine just sat dormit for like 7months. Plus the extra noise and time could of been due to lack of oil in them before the head was pulled.

[NoDoz]

youtube blocked at work.. With the bug I saw earlier, you couldnt even hear the turbo spool. Is yours on that level?

[Cincy]

unless the car was accelerating past you, has well above stock psi, and an intake, you probably wouldnt hear the turbo spooling.

But yes, mine was really bad

[NoDoz]

Man, that would drive me nuts.

Just watched the video.. Yeah thats the noise

[Cincy]

Then they are probably running to thin of oil and not changing it soon enough would be my guess like Filip said.
