Need mechanics advice, and maybe a lawyer...

and as long as it didnt gouge the cylinder walls, the bottom half of the engine should be fine! the tops of the pistons can take a good amout of stress without hurting them. i seriously dont see why they just cant replace a valve or two and call it a day!

Sorry,,, I have to disagree. If a bolt was bouncing around on the top of the piston I wouldn't trust it at all. Any pot marks it left would be a breeding ground for a hot spot leading to knock,, especially on a forced induction car.

im sorry, i should introduce myself, i am an ASE certified master tech, i work at a chrysler dealership. and you are? (no offense, just asking to get to know your crudentials). ive had several experinces with pistons smacking vavles and a couple of bolts getting into the combustion chamber, the piston may have a mark on the top, but they CAN take a beating. and seriously, i DONT call 7 psi boost anything to worry about! especially under "normal" driving conditions, i doubt that car is even hitting 4 psi! i just saying!

Before I let them expire,, new job clean hands,,, I was ASE certified Master Automotive and Master Heavy Truck,, I was a professional mechanic (before everyone got their panties in a bunch and had to be called "technicians",) for 16 years. Ran a 700hp 355 small block injected alky sand drag jeep, was an East Coast 4 wheel drive assoc rules and sanctioning rep. I currently have a 2003 PTGT running 12.1 @ 115 MPH, street driven daily. So yea,, I would say I'm qualified to make statements that I did.

Not to judge you,, but it is almost impossible for the valves to hit the pistons in our motor unless the valve breaks, or pops a retainer and drops a valve. The piston are down ~.100 from deck. The 2.4 is not a piston to valve interference motor,,, valve to valve MAYBE. Now when you bring the pistons up to the deck,, then the motor is interference.

I also have a couple of friends named Garry McKissick,, AJ Berge who I get advise from when I have doubts on decisions I have to make,, as I will admit,, I am from a small block Chevy back round, and this small displacement turbo stuff I have been playing with for only about 4 years now,, but not doing too bad I think

well thats cool! i was only asking just cause on other message boards im on poeple shime in with absolutly NO automotive experience whatsoever! im not tyring to start anything! dont need any bashing! and hey, i still call myself a mechanic! LOL! anyway. i wasnt refering to the 2.4 engine being a vavle-bender, i was just implying on other motors (from other car makers) ive worked on and have seen other techs work on that pistons can take a punch somtimes! i should have made that more clear in the above post, but i was at work at that time and was pressed for time!

i think at this point were bustin our heads on this for nothing cause from the sounds of things our opionions prolly arnet gonna be heard, and im sure that his sis is just gonna drop in an engine anyway! idk? but i had a discussion between our other master tech thats been at my shop for numerous years and we both agree that worst case scenario all the guy prolly needs is a clyinder relined, a new piston and rings, and a new head and new valves for that clinder(i know that chrysler heads dont come with valves or even seals). that wouldnt add up to 5 grand! but anyway, whatever you choose to do, good luck!

Hey we're glad to have both you guys around. That makes about 4 or 5 Master Techs or equivalent on this forum to give sound advise when it comes to things really technical. Most of the rest of us (including myself) have been back-yard mechanics with a lot of years behind us doing all sorts of car related work. I've been toying with my cruiser and answering questions since September of 2000 not to mention being on almost every PT forum around so I've seen and heard almost everything but there's still a lot that's way to technical especially around turbos.

I wish everyone would fill out there profile, because I for one look to see a persons background to give credence to what they say on the forum.

Anyway, I think we beat this "bolt" thing to death and it will end up with a new engine with the insurance paying for it.

Hey Guys I have a question it was said that the 2.4 was not a interference motor is this confirmed? I have been told and heard different on this forum.
I do know that the 2.0 is an interfernce motor I have seen the wrong end of this story..

Not to judge you,, but it is almost impossible for the valves to hit the pistons in our motor unless the valve breaks, or pops a retainer and drops a valve. The piston are down ~.100 from deck. The 2.4 is not a piston to valve interference motor,,, valve to valve MAYBE. Now when you bring the pistons up to the deck,, then the motor is interference

.


The reason I want to know this is if it is not an interference motor I will not change the timing belt till it blows but if not I want to change it soon since it has 90,000 miles



I too was ase certified but after the last 3 years of starving from christmas till after tax returns,working on comision, I got a government job in 1997 that I work 3 days a week, after that I work in a small local garage doing alignments and light repair. So I am not all that up to date on the new technology.

i would NEVER wait till a timing belt blows, interfernce motor or not! cause when it blows, it may be in heavy traffic, on the highway, or in the rain! then u gotta tow it home, (tow bill!), then realign the timing. if you change it BEFORE it breaks, then its just soo much easier!
