Default Replaced Headgasket,Timing Belt & Pulleys, but not running just right yet...

'04 PT Cruiser Non-Turbo 184K miles

This is my brothers car and it broke down at the same time he was put in the hospital for major back surgery. We discovered it had a leaking head gasket, the head was warped 0.007", and the timing notches were off a tooth (exhaust notch 1/2 tooth above intake instead of vise-versa). My cousin and I replaced the head gasket, timing belt, timing tensioner/pulley, and water pump. Also had the head leak tested and resurfaced.

We have the Cruiser buttoned back up and running. It started right up but we shut it off after a minute of running and tried to start it again and had a lot of trouble getting it going. It ran pretty rough once we got it going again and finally got to where it would stay running on its own.

We haven't road tested it but in the driveway it has a hesitation when you give it gas to take off. There is also a chirping noise every few seconds. Kinda sounds like a pulley, maybe the tensioner cause it felt loose compared to the removed one. The engine also seems pretty noisy.

So finally my questions, is the chirp something to worry about? Could the timing be out and causing the hesitation?

We were very tedious to get the timing right per the diagrams so I don't think that could be an issue but is probably worth tearing back into to check considering the last mechanic got it wrong or it jumped time.

What do you guys think? I just want to make sure this thing is good before we give it back to him.

Did you adjust the timing belt tensioner as described in the manual? I had to use a mirror to see the spring and tang.

I found this about tappet-like noise after an engine rebuild.

HYDRAULIC LASH
ADJUSTERS
DIAGNOSIS AND TESTING
HYDRAULIC LASH ADJUSTER NOISE
DIAGNOSIS
A tappet-like noise may be produced from several
items. Check the following items.
(1) Engine oil level too high or too low. This may
cause aerated oil to enter the adjusters and cause
them to be spongy.
(2) Insufficient running time after rebuilding cylinder
head. Low speed running up to 1 hour may be
required.
(3) During this time, turn engine off and let set for
a few minutes before restarting. Repeat this several
times after engine has reached normal operating
temperature.
(4) Low oil pressure.
(5) The oil restrictor (integral to the cylinder head
gasket) in the vertical oil passage to the cylinder
head is plugged with debris.
(6) Air ingested into oil due to broken or cracked
oil pump pick up.
(7) Worn valve guides.
(8) Rocker arm ears contacting valve spring
retainer.
(9) Rocker arm loose, adjuster stuck or at maximum
extension and still leaves lash in the system.
(10) Faulty lash adjuster.

Sure, debris could be a suspect, as could be cam timing.
Note, the PCM has no idea where exhaust cam is aligned, there's only a sensor for the intake cam.

-LOTS of people mess up cam timing- I think it's a good idea to double check it!

- If you are suspecting the tensioner- Well, listen to what Comp has to say.

- You can cut the warp out of the head deck, but you can't do the same for cam bores. Remove rockers and see if they both spin freely.

- Guys do, and I don't know how, mess up cam caps- We had a guy on the Neon boards just do this.

- Its EZ to get the wrong length plugs for a PT- Countermen readily hand out old 2.4 plugs.

-excess silicone readily plugs small orifices

Thanks for the input guys. After talking with my brother he told me there was already a chirping noise in the car and I think after running a while it has started running better. I think it just needed to cycle and readjust the the car being back in time.

Question Re: Replaced Headgasket,Timing Belt & Pulleys, but not running just right yet...

I'm glad that everything is running better for you now. I just had the same work done on my 06 PT Cruiser and it seems to still be stalling when I try to speed up as well. It starts up automatically, but my engine lite is still on and even though the temperture gauge doesn't indicate that the car is overheating, I still hear gurgling sounds like water is boiling when I turn my car off. And to boot my windshield wipers will not turn off at all. I'm not very knowledgeable about cars, so do you have any suggestions of what I can check myself or do to atleast get my windshield wipers to go off, before I resort to taking my car back to the shop (where it was for 3wks)?

They may not have 'bled' the cooling system- There's a little 'brake bleeder' sticking out the 'connector', lower part of thermostat housing.

Open this (IIRC, 10mm socket) and let any air bleed out (center foreground, slightly out of focus)



If you could check the codes (have piece of paper ready to read 'P' codes that appear in odometer):

on-off-on-off-on- (Where on is 'run', not 'start')

Post them here or just google
