Well this squeaking noise inside the engine started happening about a week ago. It is fairly loud and it only occurs when the engine is completely warmed up





It would be nice if someone could diagnose it! Thanks in advance

Pull the dipstick out. See if it stops.

If so, take your crank vents and toss em.

I don't have crank vents, the hoses are to a catch can

Next I would run it without the serp belt and see if the noise is belt/pulley related.

TRD_Celica

did that and it is defiantly not the belts, must be something internal

Did you pull the dipstick and see if the noise stops? It sounds like you are building vaccuum and the noise is coming from the plug tube seals.

It also makes sense as this is a hot-only problem.

first vtec

did you ever figure out what this was? I have the exact same problem. I started it up and pulled one plug wire off at a time, to see if the tube seal was the problem, and its not. I can hear it in the center of the motor but maybe a little more towards the intake manifold.
