Let’s carefully reassemble the valvetrain on the RH cylinder head. Get out the Permatex Ultra Grey!
I then use the TESLONG NTS 500 borescope to do a visual inspection on the LH cylinder head exhaust valves…they don’t look pretty.

Subaru is almost ready for start-up…I’m glad this job is almost done!
Enjoy!

Awesome work Ivan!!! Your work always impresses me Brotha!! Sending good vibes!
Terrible engines …junk
Sound like plug wire off one dead cylinder .
As usual Ivan absolutely top of the Automotive Repair Food Chain. "Apex Ivan"
So, I'm in agreement with the other's, did u scope the other's cylinders when u found the 1st bad valve from the beginning? If it needs rings, head machined, other valves, that should all be told to the customer up front bcuz now ur setting urself up for a "COMEBACK", let's start doing things the right way, maybe a used engine would have been the proper way to do his job?
Looks like extended oil change intervals, short trips, low quality oil are taking their toll
Owner needs to switch to 5/30 and replace pcv valve
The lash cap/shims are just for initial setup… The hydraulic lash adjusters take up any wear. So there's no need to adjust the valves again
Run the car on hydrogen to decarbon
Ivan: — Did you see that the Georgia Guide Stones got blown up and taken down. lol.. good stuff.
Ivan, as a person that sells torque wrenches the weird thing that I've found is that MOST people UNDERTORQUE things when they do not use a torque wrench rather than overtorque which is what most people expect. Even very experienced people like my best friend did this on his motorcycles. There is such a fear of buggering up the aluminum that they just can't bring themselves to torque to spec.
Those oil control rings don't seem to be doing their job very good
All around great job. I seriously disagree with having reused the head bolts, but it f you're comfortable with them, you're the one doing it.
Hi Ivan, great video and look inside cylinder.
I wonder is/has the customer been using the correct oil for that engine.
Ivan I was reading the comments in a previous video in this series, it’s blatant that a lot of people haven’t had to try and help a customer out especially on a job you really don’t want. You did and replaced what you could within the budget you had and I respect that unfortunately doing what we do we have to compromise. Awesome work man!
Rubbish engines
Possible crack between intake and exhaust valve at 20:00 in. nice work Sir.
Can you put up a link for the right angled cordless wrench ?
To be honest, if i was the owner i would have just sold the car as-is , and taken the loss. Pity the next owner when the other side blows in the future.
What happened to the "Made In Japan" quality ??
Had a Fiat Stilo 1.4 16v that consumed almost a litre of oil for each thousand km. So like a quart every 600 miles. Eventually the same thing happened, exhaust valves got burned and it lost compression. It happened suddenly, like in one moment it lost a cylinder, driving lightly on the motorway. 240kkm was it's mileage.
would it make sense to spray those with carb clean to get that off the seats?
This is a questionable strategy to fixing this car. Clearly, the left side exhaust valves are equally hammered and should be replaced along with all the valve stem seals. You have to wonder about the wisdom of replacing all this along with timing chain components when the bottom end has so many miles. You’re biting off a world of liability by short cutting this repair.
What happened to part 5??
Can't believe you agreed to do the job. But you made a great educational vid! Thanks.
Yeah, those valves in the other head are done for too. Definitely an oil control problem. That would explain the heavy carbon buildup in the head dome and valve seats. But I don't think it's a stuck PCV or bad valve guides or valve guide seals. If I were to guess, it looks like it may be time for a new set of piston rings.
Bad fuel or wrong octane? Running e85 in a non flex fuel engine?
you can try running some cleaner through the crankcase, like that bg dynamic cleaner. i presume those oil control rings are completely filled with carbon buildup and are letting oil through. might also help clean the valve seats..
