Jetta 97 GLX ,engine rattle, need help

[Kris0085]

Past two months I had thermostat replaced, new spark plugs, wires and coolant flashed. This week my engine started making noise especially when cold, after gets temperature noise seems to be less noticeable.
It's a rattling noise like there was a loose screw inside the engine.
Anybody had same experience?
Thanks

If they removed the intake plenum to get to the spark plugs there may be a rattle in the brackets that hold the back of the plenum to the head or at the exhaust manifold heat shield.

Just came back from VW dealer.
They told me my timing chains and tensioner had to be replaced.
They want 3200$$$$ for that job(((
I am broke!!!

That's a lot of money for chains and tensioner!!!! Around here you cut get the job done at the dealer for 800 dolla dolla bill! Then again, I live in mexico city.

I just noticed you said GLX so my previous response doesn't apply. Sorry to hear it's the chains/tensioners. It's definitely not an easy fix, but you can get it done for less at an independent shop familiar with VW's.
