So i was changing my oil passage check valve that supplies the cam phasors in my monoblock 1.8l Chevy sonic. Unfortunately, the ball in the check valve cannot be found. Uh sed a magnet, vacuumed the oil passage, cranked thr engine using the oil pump thr spit out the ball but no luck. Decided to take a chance and install the new check valve and today i have a P0011 over advance intake cam gear timing. I am going to pull the intake vvt selonois to see if there are sny bits of broken plastics from the old check valve and the missing ball. Wish me luck.
Great video man. It showed the importance of double checking your work. Chasing an intermittent driver issue would have driven you nuts lol. Secondly I believe you verified the timing issue without lifting a spanner (almost) by the cam crank correlation and then with a running compression waveform. Enough printable evidence to show the customer that time now needs to be spent on the tools to repair.
Thanks Rob, I have done an I20 previously with same fault recently. It seems that extended service intervals don't help when customers don't service cars on time. Money saved by ignoring services is usually spent elsewhere.
Hi rob, going to try this method on a nissan sentra. Slapping noise,. Man, Pico 7 is so tempting. Lol. Still using lower level stuff for now. Nice explanation with the cam and crank signals
Nice job. Very informative. Hope you can carry on with that job. Just for the fun it would have been really cool to use the cursors on your scope to estimate how many degrees the cam was advanced, figure out how many degrees there are per tooth on the sprocket and then open the engine up and count how many teeth it was off and see how close your prediction was. Just for fun not for any particular purpose other than perhaps to prove how good a scope diagnosis can be. Great job keep up the informative videos. Thanks

Could've almost pulled out my hair haha. Exactly what I was wanting to achieve. Thanks for the support Kirk!

Definitely the case Jeremy! Small dollars for maintenance or big dollars for lack of?!
Great explanation and great finding Rob. Really learning how to properly diagnose a car from your channel.
Awesome Aldi! I always appreciate your support!
I love videos with in cylinder captures. Great diagnostic very accurate.
Thanks Adrian, much appreciated!

Nice vid mate. Just curious when you take the cam crank capture, do you disconnect the camshaft vvt solenoid ?
Thanks for watching and no I didn't disconnect it. The known goods in the Pico library didn't state disconnected either.

Thanks Dave and I like that idea! I'll see how we go with it depending on if the customer wants to go ahead
This is a known issue with these engines, there is also an updated chain with a stronger link arrangement.
Thanks Sajiv, I'll make sure we get the upgraded kit.
Is the upgraded chain aftermarket or genuine.
Nice job Rob love the captures you got and comparison. Keep em comimg my friend
