Engine noise has increased?

Oil pressure is normal check your compression

May be pulleys or a worn drive belt, also a soft tension-er if an auto adjust tension-er is installed can do this, you can remove the belt and start to prove that the problem is here. If so start with a new belt and feel all pulleys for notchy movement, start here.

Hi Carlos,

I believe you also have an Idler Pulley on that engine. It look just about like the tensioner except that it is stationary.

You can check the pulley by.

Spraying the center bolt with a spray lube with engine off then start it if no squeal then replace pulley. Another possibility is the water pump bearings.

Sorry for delay in responding.

Did you spray the pulley with the engine running? If so you may have also sprayed the belt. It is possible the new belt could be the problem, have seen that a few times.

If making noise again spray the bolt again before starting. Also when replace the pulley did you make sure it spun freely? With some new pulleys the original washer doesn't work so well and will cause problems.

Without actually hearing the noise, all I can do is guess. Considering the engine has 190K on it, it could be a worn valve lifter or rocker arm. Worse case scenario, it could be a rod bearing which would be terminal. A good shop should be able to pinpoint it for you just by listening to it. Hope this helps.

Have you sprayed the belt? If not spray some lube on the belt. With the squeal getting louder when turning wheel could be the belt or even one of the other pulley bearings. If spraying the belt doesn't quiet the squeal try spraying the pulley bearing on the Alternator (even though it is new), A/C Compressor, etc. One at a time.
