Today Pine Hollow Auto Diagnostics takes a trip to help out Matt of Matt'sMotorz on TH-cam:
/ mattsmotorz
Matt owns a 2000 Chrysler 300M which has been acting up:
• I dont know what's wro...
If we can't get to the bottom of this, it's headed for the crusher.
Let's go!

Hope the engine stays together long enough to complete the diagnosis .
+wtbm123 haha that's what we hope too :)
Things like this literally only happen on TH-cam. This is amazing.
3.5HO is probably the best engine Chrysler has ever made. One of the best engines period. I've not been to Part 2 yet but I'd say this one is certainly getting a long strung out diag. You would make a dealership a fortune. Getting those book hours out of ya.
Yeah this engine suffered from abuse so can't blame Chrysler :)
"Don't worry about all that engine knocking. I just want to know why it stalls!" :) Geez, Ivan, don't let a rod hit you in the jaw when you rev that thing!
Shoulda maybe mentioned that knock first before the other stuff lol...
This was great! Thanks for stopping by my shop Ivan, I definitely learned a lot from your visit and had a lot of fun. It's funny, before you came I didn't know how bad the engine was because it has barely been running, just idling calmly until it gets to temp to check for stalling, and as soon as it did, I stopped. We really ran it at WAY higher RPM and way hotter than I normally would and it really highlighted how shot the engine is. I still would like to figure out exactly what is going on with the stalling because it should still run and not stall, and it definitely has gotten way worse since my long trip, even though I haven't been driving it.
+MattsMotorz Well Matt you picked one of the sharpest techs on TH-cam , doesn't get any better than that. Look forward to the next part if it runs that long. LOL Cheers
+MattsMotorz Agree with Rob! Learn as much as you can from Ivan b/c he is extremely knowledgeable and one of the best techs out there!
I have already learned a lot just from my brief meeting with him!
+Hayward's Automotive Iivan is one of the best.
+Eddie Martinez Agree
Curious what the ignition timing looked like with the knock sensor picking up that knock. Hard to diagnose an engine with mechanical issues but Matt can learn a lot from you!
This is Great, Thanks to Eric O. for hooking them up.
Ivan, you may want to try a polarizing filter on your camera. It may help with the glare on the Verus.
Interesting..can't wait for part 2!
Chrysler. Well there's your problem lady!
The oil light should be called the change engine light.
I have a 2002 300m (since new) - somebody has not taken care of this engine big time . Oil changes including trans & Brakes is about all I've had to do - I replaced the timing belt tensioner and water pump and all other belts & hoses proactively due to age. These engines will easily go 250K with normal maintenance. What model Verus are you using ? Thanks
that knocking sounds like a main bearing failure. i think that motor is destined for the tuna can factory!
+happy543210 Guaranteed.
Bent valves spun bearings don't need a scanner for that
Next on Pine Hollow Diags watch Ivan and Matt as they replace a Chrysler 300M motor.
Soooo pleased to see you together.
I fail to see the point in completing this diagnosis other than just curiosity. This thing is gonna be spittin' out kibbles and bits the next time he goes to get on the interstate.
+Mikey It sounds like they are doing it literally just out of curiosity
That engine is junk, it does not matter what you find.
"My oil light has been coming on recently"
Really?? Combine that with the fact that it knocks and this video should have been titled
"chrysler 300m engine swap part 1"
+Lustfulvengance I call the oil light, the dead motor light. By the time it comes on the motor is usually dead.
+Random Person Because by the time you take the engine out and strip it down and send it off for machine work, its easier and much quicker to install a used engine with a warranty!
Plus these cars are easy to swap a motor on, front core support comes off and the motor comes straight out the front with little difficulty.
+Random Person Whats nice about these cars is that you can remove the bumper, radiator, and front core support structure and pull the engine straight out the front.
I agree these are very nice cars and have a really nice ride to them.
The nice part about rebuilding the engine yourself is you know its done correctly and will be essentially a new engine.
I rather like rebuilding engines myself, I just dont at work because of the cost associated with it.
+Random Person Here in Florida where I work labor is right around $100 usd per hour, multiply that times the 20 or so book hours for a rebuild plus parts and machine shop fees and you end up with a very expensive bill....
Hey Ivan keep your head down...sounds like it's about to take a lunch break. LOL Take it's blood pressure before you rev it too hard!!!
Moral of the story women never look at gauges or listen to the engine , if they overheat one they will drive til it dies , if that happens scrap the car. If you cook a motor it's done , if you see the car start to run hot by looking at the gauge and you stop driving you have a good chance to save the car with a fairly easy fix. A man that has some sense will find water if it needs can limp the car to a shop or home without damaging the engine .
Chrysler?...Well, THERE's YOUR PROBLEM!!!
Love the video. I had an intrepid with the same motor. I cleaned the throttle body one day and found a bunch or carbon deposits. I almost suspect that the iac/tb is sticking which is why it's stalling. Funny how with a vacuum leak the motor pulls fuel. I am having some drivability problems on a map car myself and I'm interested in what you find out. Let's hope the motor holds out long enough..
The M54 on my Beemer had the exact same noise and ran like crap. Traced the problem back to a massive air leak in the pressurized oil system. Cause of the problem - forgot the replace the oil filler cap after I added some oil. Put the cap back on---problem solved!
Physics and Material Science! You'd think they could turn the thing into a time machine.
Well whatya know, engineers/scientists must love these 300m’s 😊 MechE from Philly!
That knocking is really hard...
Haven't watched till the end but this engine needs disassembling
Sounds like you and Matt got your hands full with this one. Hopefully, the engine won't take a dump before you get through with your diagnostics. Take care Ivan...
+stuzman52 Hey Terry! Yeah we'll make the most of it at least in terms of educational and entertainment value :)
+motoYam82 That's right Ivan...it's all about education and entertainment. And the important thing is that you're having fun which looks like both of you are having. Have a good one!
Problem child is definitely an appropriate title lol
I had a 2000 Concorde Lxi with the 3.5. It made the same knocking noise when it got hot and would stall. The issue was timing was off and the right bank wasn't getting any oil. So maybe that's the knocking.
What a waste of time... engine has major mechanical problems, what's the point of running computer diagnostics
Good vid as always, but the glare on the screen didn't let us see what you were talking about . Keep the videos coming , good information . Look forward to them .
I think that purge solenoid may be normally open and commanded closed.
We just got 2002 300m a month ago ran fine no problems except a new strut and the electrical issues with this make out of no where bad smell and sounded like misfiring then died we were 4 blocks away from home husband tried again and made it 2 blocks wouldnt start back up so it's been sitting 2 days have no clue the issue
Another great post. Was wonderful are you still working on post grad studies or going full time diagnostics
With the rod knock the engine is shot, plus it's a Chrysler.I had a 97 Bonneville which on a 140 mile trip one way decided to start overheating, I was half way to my destination so I continued on, a couple of hours later I started for home got on the highway and after a while the temp gauge pinned, I got off the interstate and there was a gas station, I got the radiator cap off and it was bone dry, I filled up the radiator and drove home about 70 miles it didn't overheat but I barley made into my driveway and the engine just stopped, the next day I tried to start it and nothing happened so went to a mechanic friend of mine who said to get right home and remove the spark plugs because the engine is htdrolocked, he said to crank it, I did and all the water went flying out of the cylinders, after doing some research on the 3.8 I found that the intake gaskets and the plenum had an upgrade, I replaced everything and she fired right up but smoked until all the coolant and water were blown out of the engine and exhaust, there was no damage, that 3.8 is a great engine.
Thing sounds like a diesel.
24:39 ... that noise scared me first time I heard it on my Jeep ... noisy EVAP purge solenoid. Not the rod knock.
Hey Ivan ,good morning I was wondering if your gonna do a labscope video series.Going through the finer points of a snapon scope. ?
What a waste o time!! Lol
Honestly!! That engine is toasted. You have a misfire, so how can you trust the fuel trims or the O2 readings?
I won't even look at this engine.It's done.
nice rod knock. pull the engine for replacement.
Yeah geeze why bother with it! as its toast.
How about getting that set up the Paul has where his screen does a PNP (picture in picture). I wonder if it is expensive or not??? Another great vid, tractor was a really good one.
Sound's like it not going to live long?
ah it whil live until somting comes out from the engine
Why wate time on that motor at this point. Other than to learn what is going on there anyway! Ivan will fix it then the motor will let go but we found out what was wrong.
18:33 there is your problem lady!
that engine sounds like bearing gone maybe . have to wait for next update.
great video .
I am thinkin it may eventually send one of them large round things through the side of the block.
We do know that the engine computer knows everything EXCEPT combustion chamber pressure...so I think I agree with measuring the compression like Ivan has done so fare..
Engine knock.....never overlook mechanics.....especially in this case...
Hey there Ivan... it appears ye have the good version of the Verus from Snap On.. while I believe your sometime cohort at SMA opted for the more prablematic model "Steer clear ovus from "Scchhnap Off" ....yeah it is a small world after all! good vid, look forward to conclusion
As we view this video on the Chrysler 300M and its 3.5 V6 that is not running properly, Ivan already has diagnosed the problem. He is just letting us stop and think about possible causes.
I went to this Mopar site and investigated differences in the Chrysler 3.5 V6 high output versus standard output engine.
www.allpar.com/mopar/V6/35.html
Scroll to the part about the revisions in the 2nd generation 3.5 V6 engine. Direct quote from the article. "The size of the exhaust valves and the shape of the exhaust ports, manifold and catalyticconverter entrance were optimized for maximum flow exiting the engine. "
So if MattZ got heads from a standard output engine via the salvage yard, they would not allow as much air mass to enter each cylinder as the piston moves downward on the intake stroke. Less air mass means less fuel required to keep the air - fuel mixture at stoichiometric or balanced conditions. But the engine management software is injecting fuel expecting more air mass. So the air fuel mixture is overly rich as reported by the oxygen sensors. So the engine management software has negative fuel trim of -20% as it is trying to take away sufficient fuel to get back to a balanced state.
The vacuum leak provides more air flow / mass which seems to satisfy the engine management software. And the engine runs better.
So if the heads were replaced with those for a standard output engine, the problem should disappear. But then there is the mechanical problem with the engine knock
+acarl1018 Fantastic research. You get extra credit points today :)
Hook up an oil pressure guage! Bearings toasted due to coolant leaks.
why didnt u just check the Purge Solenoid to see if it was faulted open. The stalling problem is an Air Fuel issue. the knocking is a deathblow.
I have the same problem I don’t know what’s wrong with it it just shut off and i thought it need a jump but that’s not working either I need help please idk what’s wrong with it
Hi im in philadelphia i also have a problem child a 2001 Chrysler concorde its become a headache but its my main car all t types of ppl wanna tell me what it is but noone know a gd mechanic to take it to its been over heating i got a new radiator a new thermostat Now my question is. Ive heard that it's very easy to put the thermostat on backwards is that true??
not being mean' but why would you waste time on a knotting motor ?
Didnt really notice for so long those motors were longitudinaly mounted lol
I find out that the 2000 Concord's , 300M's and the LHS have no re-sale value. I just bought a 2001 LHS for $300.. Will it take me from Salt Lake City to Orlando and back again? The LHS has 172,567 miles on it , please share your opinion. I leave on May 3rd and must be back in S.L.C. by May 14th !
I think they are very underrated cars! It's all about the maintenance. If it was well-maintained, then it will go a million miles without a hitch :)
a bad purge valve could cause this problem.
Hello Ivan. Can you make a video about your educational background?
Kind of a waste to spend time diagnosing that car since the engine lower end is junk.
I am going to guess the timing is off since the heads were replaced with used ones. That particular engine requires you to set the engine at TDC, use a special tool to lock both cams in place (in the back of the head) and then loosen both cam bolts with the timing belt on and tensioned. Then you tighten the cam bolts with the #1 piston tdc, and cams locked. Was that procedure done with the head swap?
+m ph Yup. That was done exactly. I had the special tools and followed it to the T. The timing is fine btw.
+m ph Yeah nothing wrong with the timing in this case. Like Matt said in the intro the car ran decent for a while after the repair, but unfortunately looks like the motor was doomed even before the head swap...
I Ayham from Syria Thank you for the videos I liked very
Bromance here!!!!!!!
Good to experiment on but it’s crying for a wrecking yard lol
Wow. Dat engine knock.
+Adrian Kingsley-Hughes I was afraid to rest my Verus on top of the intake manifold for fear of a connecting rod shooting up and destroying everything XD
+motoYam82 viral video!
Ivan, this could be an ignition issue....
Anybody else hate the sound of Dodge starters?
Cuanto valeun Scaner como elque estas utilizando?
did you retorque the head bolts after a few weeks>?
Dead zero LTFT's looks suspicious to me. No change at all!
Serious problems!!! On the short block...
I found that there rubber vacuum lines have cracks (back of motor passenger side) time 9:14 (rubber elbo)
damn! your findings will be interesting! later you might need to put a brick on the gas pedal and see what pops!
+eric smith That's the plan lol! Can you guess which cylinder it's going to be?
Probably maybe one in the middle of the heads. Yeah no real idea but that knocking noise sounds like a big hot mess! Look forward to the next video! I like the way you do your diagnosing and getting all information and being able to reproduce symptoms!
So is it Dr. Ivan?
I guess smog controls are worse than when I went to college....lower MPG's, lower customer satisfaction.......increase cost...
That thing sounds like a 7.3 international 😂
Kickin a dead horse on this one brother.
+Bill Balding For the sake of science!
I get it and it was good and thanks.
Very good guys but I have A.D.D. Had to fast forward some. LoL
and just imagine the result with FIAT running Chrysler?
"Chrysler" and "problem" in the same statement. What else is new?
3.5l diesel .....
Obviously you don't know shit about anything mechanical .
I have no explanation on how plugging a vaccum leak helps an engine........unless it was a long term fault that was compensated for...
Seems like a leaky fuel pressure regulator... and/or a bad motor!
You keep on kicking but you can't come in!!
O'scope the primary ignition at least......jeez.
bromance !!!
She 'aint gettin' 'nuff air man!
knocking like a tractor there, bigends or cam etc, burn it
Man this guy spent all this money throwing parts at a junk engine.
You had me at Chrysler. But seriously, why does anyone buy this shit. Research reliability before you buy.
As a mechanic, what is the most reliable vehicles you work on?
Yep, digging up old videos, they just pop up in random order it seems, since I haven't seen them all.
I don't know why your doing this one Ivan sounds bad.
The guy has a twitch to the right. I would call him twitchy if he was my new found friend.
one those aluminum engines cook, they never want to run good again.!!!
Donde Baas para cambiar el aire acondicionado en 300
Chrysler 300 poner el aire condicionado
timing ?
Motor knock much
you dont need to fix the car you need to fix your girlfriend
Ivan this is a difficult video to hear. Between the traffic and wind-------------not good
replace engine dot com :P
Wasting your time, scrap it
and that was a truck
A lot of idiot's on here don't know how to take care of a good car. Overheating a car to this extreme is bad for any car . I have 390,000 miles on my 3.5 still runs great . One of the best cars I've ever had . Better the pos Honda I had that's for sure .
it is a Chrysler you know. They work for about 5-6 years and then junkyard time
