amazing! most helpful video I've found on this topic. non nonsense, just pure logic! I did have trouble with the very last thing you said.--> did you say 'valve train'? If so, how is that checked in relation to the first tests? Wouldn't that be the first test?

Little burnt valves can drive a mechanic crazy!!! In my experience if i ever get one burnt valve im gonna replace them all. I did one once and replaced the bad valve. Put back together 2 weeks later another one went bad took back apart replaced. Two weeks later again same thing i just left it and said f with it lesson learned!

I got 2011 f150 3.5 and timing chain jumps, put new one and test moving the crankshaft and the chain jumps in certain time and tensioner compress and decompress, is that is hiting a bend valve?

@B9poy 4 ай бұрын

Hey i got a 2011 F150 3.5L too and replaced the timing chain also, i'm here because i have no compression and the valves aren't fully closing causing the engine to turn but no start, i advise you to get an endoscope from amazon to check your valves i got mine for 50CAD

@@B9poy i buy one, but before I open the cylinder head take all the valves out, notice one of them was rust and it was hard to take it out because of that. I clean all very good take the rust out, put each one back in the place they were before and all are smooth. Think that was the problem, rust. Also I didn’t before put oil in the cams, so now iam put in oil in everything before start the truck, in case the oil pump miss something lol.

My Econoline only shakes after warming up. No engine codes. Air flowing out of the oil fill tube. Some smoke or steam out of the exhaust pipe. I replaced the faulty water pump and used both head gasket sealer and oil seal. It seemed to reduce the smoke a lot but when I press the gas in drive or reverse the van will barely move. The scanner picks up knocking, only with Forscan and not other scanners like BlueDriver. I am wondering what it could be. It mainly shakes on the driver side of the engine. I really hope it's not the a cylinder or wall. Please share some of your expertise with me. What about leaking valve seals, a bad sensor, etc? The temperature on the scanner shows much hotter than the guage on the instrument cluster. It barely moves. I am so confused. Thank you.

Zero reading in cyl 1 and 3, 180 psi on 2 and 4, took head out, gasket looks intact, valves look ok too, cyl looks ok, all crosspatch are there some carbon buildup but vehicle has 209K miles; it was driving fine for few minutes and started overheating due to low coolant; old fluids, stopped right away, let it cool down, drove slowly without letting temp raise to home, shut down ignition and never started again, cranks but not start, then did the compression test mentioned with those results...any thoughts?

Hello. Sorry to say your head gasket is blown. The cylinder head is most likely warped as will need to be resurfaced.

Hi thanks for sharing your knowledge its very informative, just one question can i do a leak down test or a dry test when the cylinder head is still attached to the engine? Reason being,on my w204 i met an accident and the timing chain slipped of, my mechanic says my valves are bent i just want to be 100% sure before i can start working on changing the valves,can you advise

Hi, great videos. I live in Sydney Australia. My 2007 Toyota Corolla car with a 2ZR-FE engine has a ticking/pinging/knocking noise on acceleration and on idle vibrates a bit. There's no oil in the coolant and no water/coolant in the oil. I'm not losing coolant or oil. However, I found compression low in cylinders 3 & 4 (C1 & C2 125 psi C3 & C4 75 psi). I placed oil in C4 and redid the compression test - no change. The funny thing is when I start the compression test on C4 first it gives me 55 psi. But when I do C3 (75) and then go back and do C4 - C4 comes up 70 75 psi - weird! Anyway, without taking the head apart, how can I tell if there's just a hole in the head gasket between cylinders 3 & 4? Is it unlikely to be a valve if both C3 & C4 have low compression? Cheers, Jim

Hey thank you for you videos. My car is at the mechanic and he says the valves are bent because car is out of time. He is say we need a whole new motor is this true? Why can't the valves be changed?

@Top5AutoRepairs 10 ай бұрын

The valves can cause damage/puncture the piston head and if the valves break off it can damage the cylinder wall.

im after a misfire i cant figure out. ive done the following test and the look normal, copression test ok, leak down test ok, smoked test ok, ruled out good spark plug an good coil and good injector, no intake leaks. only thing i notice is misfire ONLY on idle. if you press gas just a little say 1k rps NO MORE MISIRE soon as gas released there is mis fire cylinder number 1 only . 2014 vw routan 3.6l v6 engine. thank you . yes i have pulsing limp noid light for injector and i do have spark on coil. thank you.

Check idle air control valve or upstream o2 sensor(s). A stuck valve is also a possibility, but much more invasive than the first two.
