S58 build gone wrong...the teardown

Dave walks us through another build built by someone who should stop working on cylinder heads.

[@CJ5EVOLUTION]

Bad examples, are always a good example of what not to do or get.

[@goyocarreras]

I don't understand how there are people who can do that kind of work. Keep uploading videos Dave, we all learn something. Regards.

[@headgames]

thanks!

[@TurboVisBits]

right? Like.. spent the effort for a CNC port and didn't bother to even take a sanding scroll to make the seat flow with the port lol...

[@lexeg1]

This is why I'm always afraid to take my head to a machine shop

[@headgames]

You have to know for sure that you are dealing with a smart one for sure.

[@lexeg1]

@@headgamesyeah that’s why I’m going to go with you guys. I have a date with jay from real street. At the end of this year. So I hope I can get a head done by you

[@wyattoutlaw2370]

They probably took the good valves for their own car.

[@newagetemplar6100]

Dude that heads shocking !!! WTF were those clowns doing.. obviously not professional engine builders with history and a good reputation .. There’s nothing wrong with posting content like this , it makes people aware of issues if people try to cut costs. Most will respect you more especially when you go into detail regarding measuring the stem height etc etc . I subscribed simply for this reason and because we have an S58 . Also there is very little information in circulation with this engine. It’s been very helpful and informative for myself and no doubt others too . Thankyou 👍🇬🇧

[@headgames]

I just think if your on this page, we should be discussing HeadGames but..I can say that maybe it shows what else is out there and why you should come here lol idk. It's a battle for me for sure.

[@georgedreisch2662]

Thinkin y’all nailed it, with the “window licker” assessment, but, think it’s multi-level, one for the guy doing the work, two, for the customer giving the nod to the absurdity of the work proposed.

[@headgames]

The customer just wanted a fast car, he doesn't know much about it. Just got taken advantage of

[@georgedreisch2662]

@@headgames well then, that adds another layer, for whoever is doing the work on the car / engine for the owner, and using that machinist or engine builder, and giving the go ahead on the head work… Sounds like the car owner may be getting hosed from more then one direction, but, fully understand your not wanting to be connected to that drama.

[@weduhpeople8504]

There are car owners that should just have a reputable professional shop that specializes in their platform. As a consumer you have to do you due diligence in researching these shops by checking reviews, asking the car community of your platform of the shop’s reputation and experience.

[@wtfyoguylol]

Dave is such a legend 👍 great video, thank you

[@weduhpeople8504]

Luckily I have an experienced head porter in Socal that has years expertise and the tooling to do a proper head upgrade. Tom at Portflow in Harbor city.

[@headgames]

Tom is awesome! Good dude!

[@scoupemaster]

hi,i need your opinion on this....can the cam caps from one head can be use it in another head without any modificatios? my understanding is that it should not but i want a pro opinion on this topic.

[@headgames]

no cam caps cannot be used from one head to the next. The head needs to be line honed. Cam caps are married to the head.

[@scoupemaster]

@@headgames love the response.....just the same way i think!!!! thanks

[@Carbonarars]

Wow, that’s ridiculous

[@golgothapro]

The only reason I can figure a guy would pull after-market to go back to OEM is if the thought the after-market stuff was junk. Without it on hand, how can you be sure ?

[@headgames]

The same shop has done a few heads that have been coming through here and I know the spring kit they use is worse than stock. So I get wanting to remove it, but the valves are great and would have worked with the stock spring kit. Would have been a better alternative to removing seats with a screwdriver or chisel how they did.

[@eldanel19891]

What a bad job, too many machine shops do this type of bad work.

[@kchanguito]

What if only misfire at idle ? , with all other things check Compresión Spark Coil Injector Fuel pressure and pump ?

[@headgames]

check the cam caps, sounds like you checked everything else

[@SupraSav]

Not sure how this happens. Don't bring your S58 to a circus to get worked on, or try and save money on things that need to be done properly by the pros.

[@headgames]

Some shops pose as professionals and if you don’t know what you’re looking for you won’t know what you’re getting.

[@khemrajhsamaroo3671]

Great work as always, question....how do you measure spring height and if it's not within spec how do you adjust it

[@headgames]

[@headgames]

later in that video I show how to check spring height. And, yes, we always adjust it.

[@K03sport]

hoping that guy got the aftermarket stuff back (in a box) 🤔 well, if do not know what is 'wrong', you'll never know/understand what is right/correct. the two have to exist together... 🏁

[@headgames]

he did not get anything back

[@K03sport]

@@headgames oh snap...it probably ended up in the other shop's car (how very Hennessy of them)... 😳

What is the appropriate amount of time between oil changes on e85?

[@headgames]

Good question, not sure. But I don’t think it’s a one hat fits all type of thing.

[@LT64444]

@@headgames I do mine every 3000. I figure thats okay, but I have heard of others doing it sooner.

[@funfun8095]

I have a BMW N20 engine I want to rebuild, but I can't find a rebuild kit for it. Any idea where I can find one? Also will need head redone. Who do you recommend for that? Just found you. Thanks in advance.

[@headgames]

We have an N20 head build coming up on KZbin! No clue on what’s available for engine stuff.

[@anthonyboria5738]

Hey Dave I saw your 2jzge vvti video vs 2jzte non vvti,so my ? Is it just as simple to swap heads from a toyota supra 2jzgte to a 2jzge and now you have a supra now for example from my is300 2jzge is that possible to take a 2jzgte head off a supra and will that give me in a sense now supra power or is there more involve! Love your videos I've done head work before on my 08 honda odyssey engine so I've pulled heads before and if that's possible I'm just curious, okay pls lmk thanks very much

[@headgames]

I don't think it is worth going from a GTE head to a GE head on a Supra. Unless it is an NA-T combo then the VVTI head is a perfect fit. I know they all bolt on but I am no swap expert on the rest of that deal. Thanks for watching !

[@anthonyboria5738]

@headgames ok it looks like I'm catching up with what you meant nat engine! If that means naturally aspirated then yes I have a 2002 lexus is300 2jzge bone stock engine so all I wanted to know is if the head from the supra will give me more power and is it as simple as swaping the heads had to figure out what NAT meant lol I'm a nooby!..Dave sorry just trying to know if I'll need to do more or if I can just again swap a head off a supra and slap it on an is300 stock 2jzge block if that's more clearer maybe I confused u sorry for my Grammer in putting this questions together..appreciate your time!!

[@headgames]

@@anthonyboria5738 don’t worry! I just needed some clarification. Don’t switch heads, stick with what you have. There’s no gains.
