CRACKED CYLINDER HEAD? - FOCUS ST

[@link4eva10]

You moved caps from another set to use on a different CamShaft?

[@Kingofthewildfrontierr]

I started watching your channel about 2 months ago, keep it up man, I love your content and can’t wait to see the final motor build!

[@Maugris333]

Supertech head gasket is 1.2mm for $75 and what I think Speed Perf6rmanc3 uses in the big boi builds. Mountune is thicker at 1.475mm but 5x the cost...Supertech it is!

[@tbr.performance]

Do you think the super tech gasket will make up for the 9 thou of material that was removed from the head?

[@RC_KAI]

Dude, I don’t know if you do already but you definitely need your own shop or have a performance tuning collaboration of some sort. You definitely have talent here!

[@tbr.performance]

The Real K Unfortunately I don’t have a shop or have collaborations with performance shops. That’s the goal but for now I just work at Toyota lol.

[@baxinst4102]

where did you find the 4 port head at? i cant find it anywhere?

[@frankmontez6853]

Is it aluminum block engine ? I've possibly timing chain slippage and maybe bent rods / valves ? This mechanic said in that case most likely a engine replacement .. That the aluminum engines don't take too much overhaul major work ? Any help will be appreciated . Small 2.0L Ford Focus

[@greenmonster1250]

I need a head just pressure tested it and it is cracked right we’re yours was were can I get a new re man head for my st turbo ? Thanks and love the videos

[@tbr.performance]

bill darnes Yeah! You just have to find one that has been pressure tested. I got lucky and found someone selling one that he had tested and resurfaced.

Hi where can I buy cylinder head st focus 2.0 2016

[@Bladesje]

I wonder how much power the balance shaft delete gains, and if deleting it can cause damage long term to the rotating assembly mass being off balance, vibrating the crank and bearings

[@tbr.performance]

J Blades If the rotating assembly is balanced from the factory, which it should be, it won’t cause any harm. It’s meant to make the drive more comfortable for all the people who can’t handle a little bit more vibration.

[@kooletron174c3]

We're u loosing coolant with the cracked head ? Enough to drain coolant from the resivour

[@tbr.performance]

This head was not on my car. I did crack a different head later in the build but I immediately stopped driving because the white smoke was ridiculous.

[@kooletron174c3]

@@tbr.performance I see ! I've noticed a small amount of smoke at startup just recently that isn't condensation. Checked my oil , coolant , plugs , they all look great . And this morning it didn't even smoke ... kinda out of options of what's wrong if anything haha

​@@kooletron174c3your issue sounds like my current issue smh

[@alezpene8703]

if you have an st it WILL 100% either blow the gasket or crack the head before or around 100k miles. FORD needs to own up to this bullshit. mine blew at 80k never even drove hard or tracked. we need to start a class action on ford for this shit.

Bro i am almost st 100k and I'm losing coolant smh

WoW. More, modern junior ' engineers'. Don't they know/ been taught, laws of thermo dynamics ? I'm not an ' engineer ' but just a hands-on, practical guy ! WHEN you force/shove extremely hot, pressured exhausts, of multiple cylinders, into ONE AREA, the same volume as each one, YOUR GOING TO CREATE A HUGE PROBLEM ! The back pressure, of forcing all this volume of exhaust, into ONE SMALL AREA is a recipe for WHAT YOU GOT; a cracked aluminim/manganese head ! TAKE LESSONS from your grandfather engineers, and HAVE A SINGLE EXHAUST, MANIFOLD FOR EACH CYLINDER. It's n o t rocket s c i e n c e......anyone, with LOGIC could easily ' see ' this problem. GOOD LUCK, MR FORD MAKERS !.......you'll need it.

[@petersack5074]

5:00 Time.....See, TOLD YOU SO ! Those ' engineers ' are NOT engineers......just engine ' makers '. .....and not very good at it, either are they ? Yup, simple child LOGIC, wins the test. Hey Ford, wake up and get us 'old guys ' to design your engines.....you'll be all better off. Another item, of LOGIC. A turbo, on a very poolry designed, engine block/exhaust manifold, is a no - no. The distance, input / exhaust air must travel, is VASTLY DIFFERENT, between cylinder 2, 3 than from 1 and 4. So, 1 and 3 get less air, than 2 +3. Simple logic, right ? Distance travelled, is time dependant. Having a poorly 'engineered ' ? block, with a turbo, and a NORMAL LIQUID COOLING SYSTEM, is another NO NO. There must be a larger radiator, and better water jacket routes, DESIGNED INTO THAT BLOCK. IT SHOULD BE CAST IRON, this metal, has better thermal integrity, than soft aluminum; also better thermodynamics, of heat transfer, expansion. Gas engines, with a turbo, IS A NO NO. Very few, large truck engines, with turbos, have problems, like shown in this video. SMALLER, NEWER IS USUALLY NEVER ' BETTER '. OLD SCHOOL, designs, NEVER HAD TROUBLES LIKE THESE MODERN toy ENGINES, designed, by doofuses, and repaired, mutlitple times by fed-up hi-tech mechanics. One day, soon, somethings' gotta give.....and not $$$ by '' we the people '''.....the consumers, paying doofus engineers, and car companies. Good day, all. good luck, with your modern junk. I will keep my 1996 chrysler intrepid; 304,000 + miles, no oil burner, and good tranny.....bye bye.

[@luckyreed1152]

I have a cracked head, was hoping it was the stock turbo seals but no luck!

[@kjj8770]

How did you diagnose I have the same issue

[@luckyreed1152]

When I went to replace the stock turbo coolant ran out of the downpipe, engines out of ford escape's are the same but WAY cheaper! I think just the intake and maybe starter are different.@@kjj8770

[@bones0184]

Bpv/bov controlled by solenoid or running a line from manifold , which is better?

[@tbr.performance]

Go off of the solenoid. You want the ecu to open the bov/bpv when it wants to. The boost system for our cars is actually pretty good at what it does. Once you start relying on solely vacuum lines without solenoids to plumb your boost control system you start running into issues because the ecu isn’t able to adjust parameters.

[@bones0184]

VALLEY CREW RACING so under lite throttle my bov will vent and stay open , kind of annoying, I search the web and a few sites said to tap off the manifold will fix this , I’m kind of thinking it may need a tune , I’m using a ots map from the Cobb access port at the moment.

[@Rbhighperformance]

hey do you know if the valve guides for this head comes inserted already from factory? im trying to buy valve guides by itseld but i cant find them

[@jamestomlinson1868]

Hey on the cracked cylinder head - was it cracked inside the exhaust leaking coolant?

[@tbr.performance]

james tomlinson Deep in the exhaust port, there was a crack because of a flaw in the casting most likely. The engine had low mileage

[@jamestomlinson1868]

VALLEY CREW RACING interesting.. do you know if it’s common? I just had a head redone with new gasket new head bolts all torqued properly and I’m still losing coolant. Kinda reaching for ideas

[@tbr.performance]

james tomlinson I’ve heard that it’s not very common but it does happen. It’s just a matter of the cards you’ve been drawn. The only way I find out was by pressure testing the head.

[@turbogodstoys]

I dont think manufacturing defect, its a design flaw.. betting they will all crack in the exhaust manifold because its aluminum.. they dont make headers from aluminum for a reason, steal headers crack where differences in thickness occur like header flange (thicker) and tubes (thin metal). Aluminum thick where turbo connects thick will hold heat longer and stay expanded longer causing cracks.. my friends st had coolant coming out exhaust but nothing in engine no overheating, very very little loss coolant. Look up class action lawsuit from ford edge group

[@andreaslogothetis4852]

Hey man love this build, I'm looking to do the same thing although I've been looking for the 4 ported head but I'm having no luck at all. Were you able to find one to buy or were you going to go custom head?

[@tbr.performance]

Andreas Logothetis Wasn’t able to find one and it wasn’t in the budget. Maybe for the next engine.

[@andreaslogothetis4852]

@@tbr.performance yea they are not easy to find. Any chance you know of any other option I could take when doing this build to get better air flow to the turbo or are we stuck with using stock manifold from the ST head?

[@spacecalander]

Same engine as my 05 mazda 3

[@focusst273]

While imports have a better exhaust air flow system to the MANIFOLD.... WHY THE F@#$ Ford whent on with a design like that???? Like always, screwing things up. Great Vlog VC!

What’s going on with Treys hair!? 😁

[@petersack5074]

There should be more distance, between each cylinder, FOR A PROPER COOLING dynamic. insane, doofus engineers.
