@@valeriumoscalu7580 it definitely has a rough idle. Heavy vibrations especially because I have solid mounts. I noticed something was off right away. Unfortunately I needed to drive another 60 miles or so to get home. I’m hoping no damage was done to the block ! I am removing the head in a couple of days….
Thanks Valeriu Moscalu, Finally someone confirming my suspicions after 100s of videos on cam phasers causing low compression, especially running compression. As leakdown test was good and cranking compression was good, but misfires all on one bank on ford 4.6 3v. Guess next step is new mellings oil pump while im in there and timing components with good quality phasers.
I have already spend so much money trying to fix mt car by the local mechanics. Changed clutch plates, rings and alot of electrical sensors trying to find the fault which causes low power of the car. I noticed, a little smoke and air coming out from dipstick when removed. What could be the issue here? Please respond 🙁
I have low compression on one of my cylinders(100psi on cold engine). 2006 infiniti m45 4.5 v8. I dont wanna spend thousands to fix it. I was going to either sea foaming or throw a bottle of compression repair. What do u recommend i do first.
Hi, i have a 2010 audi a4 b8 2.0t. engine starts up and runs but limp mode. Cylinder 4(nearest to back of engine bay) has no compression at all. All other 3 cylinders have good compression. Do you think its valve related?
@@morganmorris3459 it's the valve most probably, you should do s cylinder leak down test, this will tell you exactly where you loosing compression, but most probably the melted, bent or damaged valve!
Hi, my 2007 audi a4 quattro 2.0L turbo stalls at a red light. The cam chain and tensioner broke. I replaced both with new ones. Now cylinders 1&3 have 150psi. But cylinders 2&4 only have 90psi. The car starts and runs but shaking like crazy. Can you please help me out to see what could be the problems? Thank you.
@@valeriumoscalu7580 yes, thats right, it is most likely not running, just bugging :/ kinda not really common problem, if i pour a little oil into the cylinders, it can reach a little more bar, but no so significant. anyways i have to disassemble it, just wanted to ask you opinion. thanks for the feedback :)
Honda accord f18b2 1.8 vtec 1999 year three cylinders have a compression of 10,the fourth cylinder has only 4.5,the spark plug is black and consumes oil,works restlessly in reverse What could be the cause
Did you fix it? I have the same problem, first 3 cil running at 14/13.5 bar, the 4 one is 2.3 bar, i have done 9500 rpm on a 8k limiter car so i think maybe valves or piston damage
Just got a MK7 GTI and from nowhere the dealership saids the engine is toast because it didn’t have compression. The car was driving just fine and at the 7th day of ownership it just dies on the road and haven’t start again. It crank with very low power and you can hear her backfiring while trying to start. What would be the cause I replace spark plugs and one of my coils is damage it fall apart if you try to take it out. Also I can not hear my fuel pump but there is definitely a fuel smell on the engine while cranking. Any other options I can anything else? I do have 4 new coils I haven’t put on because the car is still at the dealership
My bike tensioner stuck while in starting position. Then i instantly turn off my bike and reset its timing chain setting. But now bike won't start and no compression. Do you know the problem kindly help to figure it out?
@@valeriumoscalu7580 yes but after this incident i set again timing chain setting and check everything even clutch setting. Both valve working properly but when i move magnet it showing no resistance and no compression realizing sound. It seems that piston cracked or rings are broken. So according to these inspections Sir what is your opinion?
Yup. Change your oil every 6 months or 5,000 miles even if the manufacturer recommends 10,000 mile oil change interval. Also never let your motor overheat.
