after having my tech install a new timing belt kit, the car is very noisy. He said it has cam end play. Hoping for your in put on what to do next.

If I remember your first post, it broke while running. I know the 2.0 is a interference motor. You may have a bent valve or three and the noise is compression leaking out as the cylinder fires. I would recommend a compression check. But, it could be the tensioner (spelling?) on the timing belt, it could also be an accessory on the front of the motor not installed correctly. I don't see cam endplay being the culprit if it was fine before the timing belt broke.

its also common for a werring or slight whining/whistling noise to be around for a few thousand k after a new timing belt is replaced. this has to do with the teeth and timing gears re-meshing with one another.

Garb, its alot more than a winning noise, wish you were right. It makes one noise under load and another when slowing down.

sounds as if the timing belt might be too tight. What year is it and what size motor? If it is a 2.0 that does have an interference motor, 2.4 was not.

Why wouldn't any *good* mechanic bring the cam end play up before finishing the job. I would have told you and offered to repair it also for additional money. Some mechanics should be street sweepers instead...

Its 02 not sure about the motor, its the wifes car never payed much attention. I just trailered over to a guy thats is tech a dodge dealer ship, so hope he can get it right for me. My regular guy is just geting too old. Sure hope its something simple and an easy fix.
If the belt broke with the engine running, this would be my guess to what the problem is.

cam end play amount didn't suddenly change with the new belt - if it wasn't noisy before then you are correct something is wrong.
Waterpump and tensioner replaced also ?
I just replaced mine and it was fun. If the mechanic took shortcuts he was stupid, it's too much work to have to do twice.

These engines had a problem with the camshaft position sensor, which is also what keeps the camshaft from moving from end to end (camshaft end play) They usually go bad slowly, but if the timing belt broke all bets are off. If your mechanic is a decent one and knows what he is doing, he should be able to find the cause of the noise and fix it.
The 2.0 engine is definitely a valve bender. I have a head from one of them in the shop right now and it has 6 bent valves

According to the Gates web site the '02 PT Cruiser only had the DOHC 2.4L engine. Apparently the 2.0 was not used.
SOHC engines (2.0L and some 2.4L) were interference.
DOHC engines (2.4L) were NON-interference

The 2.4 motors in the PT Cruisers will bend valves if the belt breaks. If a timing belt kit was used, it will have a new design belt tensioner included. If the tensioner is set too tight, the belt will "sing" until it stretches or seats in. These are not easy cars to work on.

hmm might be the tensioner, the camshaft position sensor or a motor mount
if you replaced the center mount on the passenger side it can really eat your lunch; i installed an aftermarket one that was slightly more recessed letting the bolt through the mount to the engine touch the tensioner
damned if it didnt go 1000 miles before it gave up and we figured it out
also that car broke two belts and no broken or bent valves

Isn't it sad that you can't work on a modern car any more without having all the high tech **** that's needed to 'fix' a car. The damn major motor companies have designed in the inaccessibility and redundancy to prevent us from keeping a car longer than 7 years. Now that electric thingos are becoming more into the fray it will become impossible to do any work on your car at all...just change the trim and fit an artificial V8 noise generator.

Thanks guys, needless to say thats the last time for that guy. It just ***** puting 1300 in a 2500 car. I that the cam shaft story was bs, just to try to cover his ***. At least he should refund the money for thr labor.

The belt didn't brake, just a replacement. Sorry I didn't say that first. John

If it had no noise before the belt was replaced it should have no noise after it was replaced.

The PT engine wont let the valves hit the pistons. But if the belt strips or breaks the intake valves can hit the exhaust valves and thats what bends them.
It's a hemi engine with intakes on one side and exhaust on the other.

To days update. 2nd mech tore it down after work last nite. 1st. h2o pump was not replaced, gee nice refund at Advance, fuel line is F@@@@ up, cover cracked, 2 teeth out of time, didn't replace tenstioner, belt was rubbing on cover. I was proud of myself for not going off and killing this ******* cause i flunked anger management class. He gave me the new fuel pump, new covers for kit, and $350. but why he needed 2 censors? I don't think sensor go out in pairs. probable just pading to bill. I don't know were the tensioner is. New mech sAYES THERE IS OLD STYLE NEW STYLE, NEW 1 IS $40 AT ADVANCE. Mean while wifie got bank loan check for new car. The fun continues tonght after work.

I agree with this, if belt is too tight it will fail early on
Two teeth off? I am surprised it ran. The Gates kit has all of the parts---belt, water pump, new style tensioner. I understand your frustration. It is so easy (as easy as anything to do with this job can be) to do it correctly the first time with new parts. I have owned my first and last PT Cruiser.
