[@frankp.2831]

Very interesting diagnosis as always. I’m trying to understand how a loose chain would cause timing to advance. Wouldn’t skipping a tooth cause timing to be retarded thus causing the exhaust valve to close later rather than sooner? Could it be that the pressure bump is caused by the intake valve opening too late? I believe I read somewhere that some engines send a brief pressure pulse into the intake runner to create a shock wave in order to improve cylinder filling during the intake stroke. Thank you.

I agree, he explains it better than a college instructor ever could 👍🏻

[@frnkjones40]

Not hard at all. Every rise on the waveform indicates a rise in pressure. That little hump was in an area where it should've remained level. Meaning that the piston was on its way up when the exhaust valve closed a little to soon

[@pingpong9656]

[@obsoleteprofessor2034]

Kudos to Dan...two things: 1) when scan tools first came out, very few mechanics could look at a waveform and understand what it was trying to tell them. That second pressure hump pointed a big finger at the problem. 2) It would have been nice to see the old chain stretched out next to the new one on the table. Amazing that a tiny bit of wear on each link would add up to so much stretch.

Dan looking like he's on a good health regime - slim and trim. You would think that car manufacturers would have a timing chain sensor to alert the driver with a Check Engine light when the chain guides pass their maximum tension measurement. That would save on a lot of diagnostics!

For a quick old school test , I believe using a vacuum gauge , would show between 8 to 15 lbs. for late valve timing . It certainly would not hurt to confirm the results with a more advanced test . However , it may point you in the direction . Unfortunately , since all modern engines don't have easily found marks , distributors or easily removable valve covers , it becomes involved . You can look at the valves with a bore scope , but getting reference marks may be difficult . Sometimes removing a #1 plug is a project . Great diagnosis and fix .

The problem is not that the belt doesn't like oil. A little amount of petrol makes it into the engine oil. Its the petrol that the belt doesn't like. More frequent oil changes can prevent a lot of issues.

Pico for the win, proving the problem. When I saw that up rise point in the waveform even with my limited Pico knowledge, immediately I said exhaust valve and timing chain problem. In school we learned 2.54 centimeters or 25.4 milimeters equaled 1 inch. In engine timing THAT'S A LOT! No wonder that poor little engine with a 24 milimeter stretched timing chain couldn't move that car! Well they brought it to the right guy who fixed it. Good one Dan!
