You noticed the crack at the spark plug area on the head right? 2.0l heads are prone to cracking at 100k miles. You take a straight edge against the heads to make sure it’s true and flat?
Yup! I saw them & decided to just send it cause I don’t have an extra 2k for a new set of heads 😅 the cracks are only at the spark plug threads & not at the valve seats…..for now. Full send or no send on a budget build 🤪. Yes the heads just got resurfaced, they are 100% true & flat.
Just a correction if u run a aftermarket intake you will pull more air so once the computer realizes that it will compensate for more fuel so it will throw a rich code not a lean code unless the inlet diameter on your intake is much bigger than the stock size inlet diameter then yes the increased volume of air will cause you to throw a lean code but most general aftermarket intakes won't cause that even without a tune but good video though
If you are talking what ecu monitor data shows on your short term fuel trims, then yes you are correct it would show a positive number (+5 to +25% etc) due to compensating for the lean condition. Although this does not mean the engine is running rich, that is strictly the ecu adding the percentage of fuel required to hit a fuel trim as close to 0 as possible. A rich condition is a rich reading from the downstream/upstream O2 sensors (which is the actual combustion performance/characteristics of the engine). As soon as the ecu sees the rich readings from those sensors, it will then change the fuel trims to a negative number to pull fuel & compensate for the rich condition (-5 to -25% etc). With a cold air intake the ecu will be adding fuel, but will not throw a rich code. The ecu will add as much fuel as it needs to hit the target of a 0 fuel trim, it will not add any extra to cause a rich reading from the O2 sensors or a rich code. If the ecu is not able to add enough fuel to compensate for the excessive amount of air from the cold air intake, it will still show a + fuel trim as it is still adding fuel. If it is not able to add the proper amount of fuel for the excess air, the engine will begin to run lean & throw a lean code from the O2 sensors. Wow that was a long reply 😅 appreciate the comment JP 🙌🏼
You're supposed to put oil on the head bolt threads and also the washer surface where it sits on the bolt boss.
Really good video bro, well done 👏 and lots of info ❤
Nice to see the engine literally ready to go, the suspense for the first start is building now
Next video!! 😈

I’m loving this series so far, very informative and easy to watch. Keep up the good work Daniel!

Nice.

Im loving these videos. Huge fan
Ayy thanks Marcus 🙌🏼

Hi, will a 2018 subaru outback wagon non turbo have a cam carrier leak/drip at 34,000 miles on the car? dealer is charging me $3555+.
