43 Comments

1. I’ve literally seen ur ad before this video

2. sounds like my Subaru 🤑

3. Man I wish we could have a Money Pit series for Zach’s Silvia. Zach and the Silvy deserves it

4. I may be late to the video but, my engine is making that noise too, yey (btw nice video )

5. Did you guys do more videos on the rebuild? I cant find any

6. Lifter tick?

7. Is it rocker arms, and or lifters?

8. Side note….one of the best sponsor plugs I've ever seen😂

9. I never thought I'd say, or comment, something like this. Haters gonna hate… That was the best add I think I have ever seen.

10. I like how they explain everything so calm like everyone has the tools at home to check for all those problems lol

11. Sorry about that, bud. …but this will be a great real-world video series!

12. There is an awesome trick to find out where the sound is coming from. Get one of those stethoscope the doctors use to listen to your heart, and connect a metal rod instead of the little pad they put against your skin. Then put the rod against different places of the engine, so you can clearly hear what part is making the noise.

13. I really want to see an update on this machine

14. People need to talk about the ad in this ep more

15. If it makes you feel any better, it was this video that clinched it for me. Became a dues paying member of the underground. Looking forward to more awesome stuff, thank you!

16. Knock knock knocking on heavens door.

17. A wooden pole or steel rod works wonders in this situation

18. you guys are freakin cool.

19. This however is a normal sound in a 3 cylinder engine. When they're cold they sound like a damaged engine. And that's very bad because you probably won't notice when it's actually damaged and then you see rods lying on the ground. I think the engineer decided that the 3 cylinder is a good solution after they had 30 beers.😂

20. Sounds like ur just in for some bearings

21. I remember when I threw my first rod bearing on my 98 Mazda B3000 passing a school bus. I just put a whole new engine in it 🤣 still going strong 5 years later lol

22. Got that Jamie Lee Curtis in Last Action Hero hair.

23. My car is making this noise now

24. 7:45 Much of the noise when this occurs is ALSO from the pistons kissing the heads with that extra 1/8"-1/4" of stroke the engine now has, because of that space in the bearing.

    When the knock progresses to that sharp, ear-shattering, jack hammer noise, THIS is usually what's happening.

25. A rod knock gets REAL loud when you hold the revs at 1500 or so, and then lightly Rev the engine between 1500 and 3000 about once per second, and keep cycling it like that.. If it's a rod, it'll get REAL noticeable every time your on the Rev part of that cycle. Think jackhammerish

26. What other reasons can an engine have to run roughly between a range of rpms say 40% to 60% ?

27. Everyone always talks about play in their engine but no one ever mentions kid.

28. Imagine doing all that and find out it's just a loose screw

29. "lets go jam those in one of my holes" 😭

30. My bearing spun on cylinder 2 o2 Nissan Xterra

31. Ugggg, should be wearing gloves!!!! Those intimate oils are no bueno to massage between your fingers! Dang, that sucks 😮

    Edit! Plus safety glasses!

32. All that for a DAMN OIL PAN removal SMH I know there’s a better way ……

33. I thought I had a lifter tapping but thankfully my power steering pump was just going out 😂😂😅❤ love the videos fams

34. I felt it when he said "its going to make me cry"

35. That's a normal sound for a VW.

36. Sounds like a 1.9tdi

37. Zachs RB sounds like a diesel lol

38. 2:50 cool little diesel you have there

39. When I check for rod knock the first thing I do is pull the plugs, and rotate each cylinder to TDC. Then I will sit an extension or something on top of the piston. Rotate it slightly past TDC and then push down on the extension. Usually you can feel the slop that way.

40. 14:19 was probably the best time to release the cars are pain shirts
    To bad the were released like a year ago

41. At that point I’d suggest replace all piston heads, connecting rods and resurface the block if a replacement block is unavailable. I’d go new block honestly because no idea how good a used one can be. I like oem not really too familiar with machine shops for resurfacing

42. still at the start but…what was wrong with it?

43. This episode is old school, back whe you giy had enjoyable episodes.
