Not my kind of car but these were the first crossovers,lots of room inside,you sit a little higher on the road all seats fold down for a huge cargo area,neat design... You could also get a 180 hp turbo or 215 and 230 hp Turbo in the GT those stick to the bumper of a 1999-2004 automatic 4.6 Mustang GT..Both mid 6 second 0-60 and high 14 second 1/4 mile for the GT Cruiser.. I own a car dealer and in 2008 or so we raced a Turbo GT cruiser against a Mustang GT automatic,both cars were a few years old with under 30,000(I always buy low mileage cars to sell)..Mustang GT hardly ahead.. I mean all car makers made ugly vehicles Toyota Echo,Yaris Honda Element,Fit,Pilot etc..A lot of ugly 2023 models around especially the weird electric cars very ugly.. PT Cruisers are not the ugliest cars,they were handy useful cars that lots of people put lots of miles on and drove them hard! My dealer I had people who owned these cars want another,for several years I would buy as many as I could..Maintain them they go 200,000 miles easily,neglect them well,you have issues!

[@johncooper4637]

When you have a leaky valve on a leak down test it is recommended that you tap the valves to make sure they are seated. Also, I have always loosened the cam bolts in order from outside to inside as recommended in the shop manual. I notice that I Do Cars does it too on his tear downs.

[@andrewgarcia3136]

yeah i'm not convinced this test was performed properly. if the valves are open then you can't tell if theyre bent or not. gotta make sure it's closed

@@andrewgarcia3136 doesnt the smoke leak down into the crankcase through the ring gap anyway? so you would see flow on the ball meter but wouldnt necessarily see it in either manifold.. in his case here its probably valves but I do like the idea of tapping them to be sure they are closed esp on an engine that sat for awhile before being torn apart as this one probably did

[@michaelchan8915]

Another great video as usual Ray!!! Interesting to watch this, since I just had a very similar such situation at my workplace. A 2018 Escape 1.5 came in on the hook with the drive belt completely sheared off due to the water pump leaking coolant onto it. Long story short, a new timing belt and water pump later, the engine has zero compression. Using my borescope, I was able to positively confirm ALL intake valves bent.

[@aenoymotors]

I've had several of those 2.4 liter Chrysler engines survive timing belt failure. The pistons won't hit the valves on those but what can happen is if the cams are spun the valves on the intake side can hit the valves on the exhaust side. The 2-liter version of that engine though is piston to valve interference.

[@Jmg831]

Good info

[@Macabri_2k10]

from last video Ray looked up info on the engine and it clearly stated it is a semi interference, the piston and valves don't interfere as the pistons never cross the path of the valves, however apparently the valves (intake and outlet) can touch and bend in certain conditions

[@dbutcher84]

​@@Macabri_2k10I looked it up also and it does appear to be only semi-interference, so I'm still lost on how there would be damage when it appears like the belt held the cams in time with each other.

[@blahorgaslisk7763]

@@Macabri_2k10 But the question is if the camshafts ever slipped their timing. The belt was stripped in a way that suggests they didn't necessarily do that as it was the cranks shaft that had stripped the belt. But at the same time you have to wonder why it resistance was so high that the belt stripped. If the cam shafts slipping their timing had the valves interfering with each other then that could be what caused the belt to stripp at the camshaft.

[@Macabri_2k10]

@@dbutcher84 we don't know the exact circumstances in which the belt failed, was it running, was it on an engine start etc. Ray also did not check if the cams where still in time he just turned them but did not put them on any mark to check, maybe it's backwards and something with the cams or valves failed and caused stripping down at the crank?!

The PT Cruiser and the Dodge Neon were built on the same platform, and you hardly find either one of them driving down the road anymore.

[@mikec2111]

When doing the smoke test it is worth also watching the oil feeds to the head. Doesn’t always work but can indicate piston damage. I have seen a hole punched through lightweight pistons before. Similarly once the cams are out but before you pull the head, a compression test can be useful (hand turning the engine first to ensure all bent valves are out of the way.) The results and a wet test can confirm no lower end damage. It can be a bear to rebuild a head only to start up and find damaged rings, damaged main bearings etc. A trick I have also used is to “bounce each valve with a rubber hammer as it both fully seats ok valves and shows the bent valves. Of course, depending on how the valve lifters work, you can often spot a bent valve by finding slack rockers before removing the cams. All investigations are quick and we’ll worth it before starting dismantling further and high cost.

[@Wakeupandsniffthecoffee]

Motor City Mechanic did a great series on checking, troubleshooting testing with various different tools. It's at least a five part video because he breaks it down by different areas. The end result was going in and replacing valves that had been bent and all the steps to do the head and valve. A great series for a PT guy like I am. Someone that knows the steps he uses can probably bypass many of the steps, but it is very useful for it's lessons on troubleshooting and the ways to use the test equipment. While this one had a defective timing belt, the one he did was sort of surprising, but came down to a previous mechanic not paying attention to details. So many mechanics will just tell customers that a PT needs a new engine or something that is obviously too expensive to justify. That means there are a bunch for sale cheap and like mine, can be returned to their glory without breaking the bank, IF you are able to do the work. I'm no mechanic, but have tackled jobs on all my cars because of youtube channels like Ray's Repairs.

Can't help but wonder if just putting a new timing belt on there and seeing how this old car runs wouldn't have been just as easy and instructive as the smoke test. I believe in this car only the valves potentially interfere. When the crank tore the teeth off that section of belt, the cams were still in time so valves were probably OK.

[@hjsn1]

You have to take the side motor mount off(which is quite a bit harder than it seems), the crank pulley, the outside timing cover and other stuff I forget about from the many Neons I've done. If you have all the tools out and know exactly what you need, you can get to the timing belt and have the head and the tensioner off in about 2 hours but there are a lot of close quarters issues that homemade or cut tools help with. I once did 2 of the neons back to back so I know from experience. It's not a fun experience either. I have replaced the bent valves though. Had my Neon break a timing belt and didn't bend one valve. A friend's Neon timing belt broke and it bent 10 valves. Simple to take them out since you have the head off already then have it machined. I've done a total of 5 Neons and the first one was the only one that didn't have bent valves.

[@RJTC]

I'd second @brianspencer6397 suggestion - full air pressure and tap each valve a couple of times to clear anything from the seats. A 0.5mm aperture is not much of a leak, I'd expect vastly more with bent valves.

[@averyalexander2303]

I was thinking the same thing, especially because quite a bit of that air is certainly going through the rings too since they will always leak a little. With such a small leak, it seems way more likely to me that there's some surface rust on the valves and seats from sitting or slight debris. Especially with Florida humidity, it doesn't take long for valves to develop surface rust like brake rotors and it only takes a tiny spec for a valve to not seal perfectly.

[@BlackOpsJuJu]

A Leak Down Test would be much more accurate so you could see the amount of leak down that is Happening No engine will have perfect sealing with 0 percent loss. Five to 10 percent loss indicates an engine in great to good running order. An engine between 10 and 20 percent can still run OK, but it'll be time to keep an eye (or ear) on things. Above 20 percent loss and it may be time for a teardown and rebuild

[@williamjones4483]

I would have just gone ahead and pulled the head. You have to visually inspect everything anyway. I don't see the point of doing a smoke test here.

[@Cragified]

True but the problem is that is because piston rings cannot seal completely. So you'll always have some leak and flow into crankcase. But leaking through the valves they should leak only incredibly small amounts on an engine with a lot of run time still on any engine that is multiport injection and not GDI as the fuel sprayed at the back of the valves keeps the valve and seat clean. The smoke coming out the intake clearly indicates the valve is no longer sealing on the seat. It may still run but it's got issues that are only going to get worse. If this was mine I'd certainly throw a belt on it, time it, and then rotate it to see if it rotates freely and then see if it runs. But as a mechanic like Ray I'd never suggest doing that to a customer as if it has an issue that lead to the stripped belt such as a valve hanging in the guide etc. it's going to come right back and screw you.

[@BobPicc1]

Don't you have to rotate the engine manually in order to get each cylinder to TDC (all valves closed) in order to do a leak down test for that cylinder? How would you do that if the timing belt is broken?

[@Cragified]

@@williamjones4483 You have to look at the whole picture. If the valves were still sealing he could save the customer money. Pull the head and not only does it get more expensive to do a guarantee level job but now you have an engine open to the elements you do not really want to store outside and Ray has a very small shop. One of the advantages that Car Wizard has is a giant building with lots of storage capacity.

You should've done a leak down test. Valves don't have a perfect compression seal and there will always be a leak, the question is how much! A leak down tester would show you that.

Why not simply connect the compressed air coupling to the compression gauge extension tube, and listen at the inlet ports for hissing noises? You would probably also detect air hissing at the exhaust tailpipe, too with 100+ psi pushing air past any leak. (Make sure each piston is at BDC when you check the cylinder, or the compressed air will vigorously get it there...)

Replacing the timing belt on a Cruiser is a fool's errand. At least on most of them, you can't replace it without pulling the engine, the cost of which is usually more than the value of the car. Even if you do it yourself to save on labor cost, you still have the problem that you own a PT Cruiser.

Tried a strap wrench but it wasn't very effective & I was afraid of moving the cam too much. Timing belt change on the mini van was difficult, Cruiser has to be worse.

Thanks for doing the smoke valve leak test for the curious amongst us. In future, remove radiator cap and oil stick to also check for coolant and crankcase leaks in case there is a blown head gasket. Doesnt matter for this repair since head coming off anyway. Waiting to see how pistons look after head off. Break bad news to customer that no start led to repair for timing belt, then head, then motor mount, then battery. See if more repairs needed once engine started. Tough break for customer. Repairing older car can be worth not having to buy new and expensive junk at dealership. My older cars are more reliable than my newer cars.

[@gottalovetheabba]

Why do you have to replace the engine for bent valves. Why not just replace the head or just replace the valves?

Every time a PT cruiser gets scrapped, an angel gets its wings. Horrid car.

[@lylejohnston4125]

This motor is NOT AN INTERFERENCE ENGINE. I worked at a Chrysler dealer during their whole build span. I've replaced too many T-belts that were broken and NEVER found a bent valve in one. I call them Pity Cruisers. One family broke the T-belt and let the car sit about 6 months while saving up the money to repair. The boss said to put a belt on temporarily to see it bent valves. I told him they're not an interference engine and went and put a whole T-belt kit in it. Hit the key and it fired right up, did the starting flare and died. Checked and it had zero compression??? The boss was pissed and said to pull off the head. I found that while the car was parked for those months, The carbon on the pistons had dried and flaked loose from the pistons. When I started it, the flakes flew off and stuck in the exhaust valves but there were no bent valves. Boss was still pissed because that's the way he was.

[@geraldyates8958]

This is a great idea to find if there’s bent valves. An easier and faster way would be to remove the timing belt, install a new one, and rotate the engine to TDC on #1, then go in the firing order and do a leak down test. This way you don’t have to remove the the valve cover and all if the other components. This way you can tell the customer what’s up a lot sooner without all the labor. Because they would be out of this $ if they don’t want it fixed.

[@Babalon48]

I was thinking something very similar, only in a way that would skip the time and part cost for installing a new belt. Not to judge or critique, but to help save Ray some of his valuable time. Try to just compression/smoke check one cylinder at a time, look into the spark plug holes to see if/which piston(s) may be dangerously close to the top, and then wrench the cams into a closed valve position. Slowly and carefully check each cylinder one at a time. What a nightmare engine to do a compression leak test on the way Ray did it, my sympathy and respect to you for going the distance on this one for an honest diagnosis good sir.

[@wessterns7159]

Have you ever replaced a timing belt on a PT.. Sorry but while on some vehicles that might be a diagnostic tool but on a pt to replace the belt is not fast or easy.. Accessing the top end as Ray did is the optimal way to "test" for leakage

[@geraldyates8958]

@@wessterns7159 I haven’t. And if it’s a total pain, I would’ve maybe put it in time by the marks without installing a belt and tried it this way with all 4cyl. I haven’t ever worked a 2.4 Chrysler. But on other cars like a Subaru, Honda, etc. you could check the valve lash to see if it’s excess. A bent valve will have a lot of lash

You're not accounting for a little bit of pressure going down through the rings you're getting a little tiny bit of flow on those other cylinders because it's going down through the rings number two and number three are most likely going down past the rings why don't you do the correct test and do the leak down

[@jamesvanzijl4348]

Great detective work Ray !

[@michaelellis2748]

Many of the comments have pointed out that piston to valve collision was not a real issue, just valve to valve collision. But the belt did not snap, the teeth got tore off at the crankshaft. Therefore cams were still synched. So once we saw that it is likely no valve collision happened. At that point it was worth replacing the timing belt and see how it runs. Didn't need to even remove the valve cover. If you went so far as to remove the valve cover. Verify the cams are still in synch. If not, are any showing a exhaust and intake valve on the same cylinder open? This is useful data. In my opinion the whole smoke thing was just silly. I think all it showed was which valve in each cylinder had the worst seal. I doubt any valve in that engine had a good seal.

[@duncancremin1708]

Right at the start, “It’s really not in horrible shape!” You’re having a laugh! It came out of the factory in horrible shape! Just like Ford’s Edsel, one should be kept in preservation, as a warning to future generations. The rest of them need to be gone, as soon as possible. I can’t believe I’m about to spend time watching Ray commit such a crime, subjecting innocent road users to this thing once again. First time I ever hoped he’d fail. In all seriousness, however, if the owner likes it enough to pay for this, then I actually do hope it’s not wasted effort. No accounting for taste, after all, and if I don’t like what I see, I can always look at something else. But I genuinely don’t like PT Cruisers. Ugly, impractical and uneconomic, not to mention not very pedestrian friendly, if you’re unlucky enough to get hit by one.

Back when these vehicles first came out the wife and I were at our local Chrysler dealer shopping around for something used but not too old. WE had just about settled on a Dodge Dakota pickup truck and a salesperson came up to us and said they had this brand new PT cruiser on the showroom floor that someone had ordered and didn't take delivery of. Salesperson tried to get us to buy it and we said thanks, but no thanks. Even then the reputation of these things was starting to be known.

Really appreciate the detail you give visually and verbalizing both the disassembly and diagnosing to determine if there is a bent valve.

Thanks, as always, for a fine entertaining and learning experinece.

[@bobhudson6659]

Each of the cam caps is machined perfectly round to size in-situ in manufacture. That means each upper cam cap exactly matches its mating lower half. If you don't keep them in order, the hole created by non-matching top cap with the bottom half will not be dead round and could also be slightly offset. That size and offset difference may only be a thou or two (many times much more) but that is more than enough to have the camshaft scraping/jamming in the camshaft housing bores. If the motor is assembled that way, the camshaft will lock up, or at minimum, gouge the camshaft bores in the head after very few revolutions. If done that way, many times the motor is scrap - not worth repairing. It is the same for big end caps that exactly match the conrods - same for main bearing caps - that applies to all engines. The caps have to be kept in order and also the correct way around. Some manufacturers have numbers cast/stamped in the removable caps (cam, big end or mains) but many do not. If everything is going to be thoroughly cleaned (and its needs to be) then before cleaning each cap needs to be marked in such a way that the identifying marks are not washed off. If not, then everything has to go off to an engine reconditioner to have all housings closed and honed - look up what that means. That's really expensive and totally preventable by careful accurate marking of all components. Retired mechanic/machinist in Land Down Under who at one time worked in the spare parts side of an engine reconditioning shop many, many years ago.

[@bearpuf]

@@bobhudson6659 Until now I was ignorant that there was such size variation in the cam caps manufacturing that it could affect the overal performance of the cam operation. Thanks for your explanation. It's appreciated. And here I was thinking that when I adjusted the tappets to a few thousandths of an inch for a valve I was doing fine tuning.

[@bobhudson6659]

@@bearpuf Hello, it is not that there is a variation in the cap sizing it is just that in manufacture and machining, all caps are attached, torqued to spec and then line bored so that the hole it creates for the camshaft is perfectly straight and exactly to size, and alignment, for each bore. Each cap is then a perfect match for the hole it is part of. Move it to another position and while close it will not be a spot on fit - and that creates a world of problems that I mentioned.
