I had a 94 Chrysler Laser years ago with intermittent low compression on one cylinder similar to this case. It turned out to be a bad valve guide. Using a compression gauge it would read bad one time and OK the next. It also fouled the plug with the bad valve. It was bad from new. The dealer knurled the guides and it worked for 6 months or so, long enough to get out of warranty. I ended up replacing the cylinder head after which it ran far better than when new. Oil in the cylinder made it want to pre-ignite. The knock sensor backed off the timing and it was a stone. After the fix I could lay rubber with it.

I just changed the heads on the 2000 Ranger 3.0 with 188,000 miles. They had known exhaust valve issues over time. Turns out I had cylinders 4 and 6 getting coolant in the chamber which was cracking spark plugs and then once I had the old heads on the bench, 5 out of 6 had brake parts cleaner leak past the exhaust valve seats. Now with new heads with hardened seats, all new head, intake and valve cover gaskets, I am battling high LTFT's. Got new O2 sensors on the way since mine have about 60,000 miles on them with raw fuel from misfires for who knows how long. Good news is that there is no sludge in the motor and the cylinder walls still have the cross hatch on them.

I had almost the same problem on a 2000 dodge G/C the only difference was the misfire was sporadic but we couldn't recreate the misfire over several months and 2 trips into the shop. 3rd time being the charm my customer brought it in when it was actually misfiring. For the misfire to surface they had to be on there way home from work with lots of stop and go traffic and the temperature was above 85 degrees and still intermittent. After checking spark and fuel that were good, it had low compression on cylinder 3 with a leak down test proving it to be a bad exhaust valve. After removing the heads we could see the issue which was a hairline crack in cylinder 3 exhaust valve. After watching this I started to think what the vacuum gauge would show while doing a cylinder balance test. Next time I get a misfire like this I'm going to have to look at this just to see if there's anything of value in it. Thank you for the great videos you always have great content.

No way to access the coil or injectors without removal of the intake. Fuel checked out, Fuel trims out of whack, no vacuum leaks. I broke down took the intake off and removed #3 coil....as I removed it, I noticed a drop of water...I looked in to the tube and saw that the SP tube was 1/2 filled with water! took the rest of the coils off in that bank and the same thing! Not sure where the water came from, but I'd changed the intake Man gaskets a couple of weeks before and cleaned the area with degreaser, and rinsed. I thought I had thoroughly covered EVERYTHING with plastic. Car ran well for about two weeks, then the misfire. I bet it was running on 3 cylinders! Anyway, I dried everything and engine is running like a top. However, I'm still leery and wondering if there is a water passage on the head that is seeping. The "water" was not antifreeze as far as I could tell. I'm hoping that maybe it's water leaking down from the windshield washer nozzles or that maybe I didn't cover the engine as well as I thought I had and it took a while for the water to interfere with the plugs.

Took it to dealer they did compression test and found out cylinder 6 had low compression, they opened engine and said found a roughness on cam lobe on cylinder 6. In your case you mentioned it was slightly lower, so did you continue to drive it like that with no further issues? The reason I ask is because I don't know whether to replace engine or/ camshaft lifters or just drive it a few more.

I did all the plugs wires coil pack, changed power steering resevoir and fluid, changed air filter, cleaned mass air flow censor in air intake to throttle body with mass air flow sensor cleaner, removed throttle body and cleaned it and cleaned the idle air control valve of carbon wasn't to bad. No help van still runs like crap idles rough, the whole engine shakes when driving, no codes. engine is visibly shaking some when just idling from cold start up to, seems idle better parked after warmed up but then it has that fairly audible clacking sound like lifter or something. I could do pcv valve and egr valve..and other stuff like thorttle position sensor, map sensor but really i think its probably in the engine the prob, I hope not. FIrst guys i brought it to muffler shop said it runs fine, so um they were way wrong of course so i gotta bring it somewhere else where they going run real tests on it like this guy. I did notice when i changed the plugs that cylinder 6 on right front part looked dark like had oil or carbon build up on it for first half inch of the spark plug the other 5 cylinder spark plugs looked clean. Also the air conditioning condenser thingy when air conditioning on sometimes the whole muffler system shakes guess that could be on way out, overall i'd say most other things on the van are in good condition.

While the engine turning since the valves also turn, maybe carbon deposits sometime dont let the valve close all the way!! 😏 Great video Paul!

That's exactly it. The valve is making and breaking the seal as it rotates. Assuming it comes and goes at a steady rate.

Yes I would do work I personally own 2 of these it sounds like basic maintainable maintainance has not been done. The breaking issue is caused by heat warp unfortunately meaning with these and many other minivans you have to turn or replace the rotors every 6 months to a year. At this point it is a bit of an uphill battle its still cheaper than a new vehicle and if you are in need of something such as a caravan then its one of the better options.... Side note may recommend an odyssey just for the lower maintenance requirements.

Soooo, the number 3 was losing compression intermittently but (face) with a regular frequency? Which would indicate that the hydraulic lifter is collapsing? I don't get it Big Dan.
@NobodyAskedForThis6 жыл бұрын
Valves rotate as the open/close. I would definitely check the exhaust/intake. There could be a seating issue that comes about as the valve rotates. Of course, could be a lifter or something else. Could be a valve sealing issue though.
@dylankinch27356 жыл бұрын
NothingSpecial if it was a valve sealing issue u would think u would se it every time not just intermittently. I could be wrong but it just seems logical to me.
@ScannerDanner6 жыл бұрын
My thoughts too Dylan but others are saying the same thing, some from carbon deposits. I would say if that was the case, it would have been an exhaust valve not an intake valve, since vacuum was good and steady on the gauge.
@NobodyAskedForThis6 жыл бұрын
I've seen intake valves carbon up. Possibly because of valve overlap, not completely sure about that but I've definitely seen it.
@NobodyAskedForThis6 жыл бұрын
I must have missed the vacuum gauge part. Most likely not a valve issue. I agree.
@neutrodyne4 жыл бұрын
A simple compression tester would have probably told us the same thing. If it was mine I would pull the valve cover off and take a look. If I had to pay a mechanic for his time I may have a different attitude about it. My guess as was mentioned earlier by someone else is that it probably has a broken valve spring which should not be that hard to replace if you can get to it.

I cant say how many cars ive had that caused an intermittent missfire even after i did everything to them. sometimes i would hear a slight tic noise, happened on my chevy tahoe with a sbc, 1 other wierd thing i noticed was if you slightly touched the throttle and held it, the rpm needle would stop and go stop and go through the sweep, replacing the lifters solved it, now my best educated theory on why a lifter would do this is accessively worn lifter tolerances, becoming even worse as rpms increase the lifter will collapse more and reduce camshaft duration as well as lift, and late valve timing events, theres just no way you could ever catch that on a compression tester snce it reades the maximum compression that cylinder produced, and not individual compression cycles produced.
@Blazer02LS6 жыл бұрын
I'd try some seafoam in the oil to see if it frees up. Maybe a top cylinder clean if carbon is suspected.

Paul I recently purchased a Pico 4425 kit. It is awesome by the way. I enjoy your videos and I am learning quite a bit from them. Quick question, I noticed the spark event was after TDC, do you recall if there was a timing issue? I was just wondering because I am not sure if I was looking at it properly. Thanks for all of your hard work.
