Compression test on a 2019 Vortec supercharged mustang GT manual 

Guess I'll be changing out my plugs more often, til i get that return style

@@Joebauers2505 or just turn the car down till you get your fuel system

@@Jb-mp1in I could but I'm not really pushing it, only running 10-10.5 psi on 93 using boostane as an additive

It fucks with the O2’s as well

@@Joebauers2505 not worth it just run 8psi and be content

I have both, a long block and a shortblock. might just get a brand new shortblock from ford through pbh

Did it puff smoke from crankcase? Lol

Yep bad valve seal as well! Lol

@@martin5.036 nope that will burn oil in the exhaust not puff out of the crankcase

Mind you I am not losing any oil either I've seen this happen a couple of times and I am almost certain it is a ringland issue as it is very common for these cars to have those issues

I hate to doubt Alex, he's right way more than wrong. But I've seen that before as well as a long time former Ford tech, but it wasn't on a coyote, so my thoughts may be invalid. If possible, pull the valve cover and run the engine and see if smoke is coming through a valve seal. I saw it one a boosted new edge cobra. But given the common issues with these cars, ring lands are more likely, but not 100%.

It's puffing smoke from crankcase....tell me how that is valve related.

@@YDBT4LIFE not saying it isn’t an issue with the piston rings, once again just passing along some info if you wanted to further diagnose your loss of compression before you just threw a short or long block at it. You do you old pal.

@@travisc.3881 it's not a valve I guarantee it I'm almost so sure of it that I'm willing to bet a short block on it LOL I'll replace the short block and show everyone that the issue is a ringland because I've seen it happen too many times a random number seven cyl valve issue literally never happens on coyotes

@@YDBT4LIFE I’d say you are spot on with your diagnosis of a piston ring issue considering the compression test numbers and it did seem to have a good bit of blow by coming out of the PCV on Bank 2.

#wherearemylikes.......

Hahahahaha

Fucking it's just a six having a heart attack thinking Alex just stole his game

Damn hate to see that. I enjoy learning about these motors. Is it common for rings to go bad? I just put a GEN3R in mine not long ago with a Gen 2 block. Want to do all I can to keep it healthy.

Why are you using a vented catch can rather than non vented?

@@horsepoweraddiction808 The intake ports are capped. There is no sucking oil vapor into your intake. A non vented one gets some oil out of the air but not even close to all of it.

@@SHOOTSHOW00 ok so it’s just a vent to atmosphere setup correct?

@@horsepoweraddiction808 Yeah. All that smoke that was coming out the cam cover is being mixed with fuel/air mix unless you vent it. It can even put raw oil into the mix. www.uprproducts.com/11-14-mustang-gt-breather-tank-system-plug-n-play/

@@SHOOTSHOW00 do you smell the pcv in your car when you are driving?

It worked for me for 2years no problems

Its crazy how many ppl dont know this 😁

@@cooterbaby3360 I really don't think it's common knowledge. I'm just trying to help out Mr. Alex or anyone else who reads this.

Killing fuel pump or matting the throttle during test

Borescope won't show a ring land issue

@@YDBT4LIFE true but could show if there’s any cyl wall damage.

Blown..

Better to disconnect injectors

I won't ever lower compression on a coyote. Makes 0 sense.

I'd pull it and show the damage.

@@YDBT4LIFE you could make some money on your hurt motor. If the damage is not too bad, you could fix it and sell it. Might as well make some money off of it.

Would like to know as well

That depends upon your altitude and if the test is done correctly

Black smoke is unburnt fuel, blue smoke is oil burning…

I knew the blue smoke was burning oil the car has 130,000 miles on it but It doesn't do it at idle only seems to blow blue smoke when I'm coming to a stop sign or red light after getting on it.. wasn't sure about the black smoke figured it was running rich just changed the plugs I put in 6510s

Yes, but shitty E is better than shitty 91/93.

@@AzureCrux I’m in Arizona we have pretty good E85

@@ATFCanEatMyDog Where in AZ do we have good E85?? im in the northern scottsdale area and ive never seen a single pump of E

@@flood2472 I’m in Tucson lol we have 3 stations that have good E85

@@ATFCanEatMyDog wow, i haven’t looked all the way down there, lucky you!

Nope. You are incorrect. A ring land issue was common on Early Gen 3 Gen 1 and gen 2 are fine. Generally

@@YDBT4LIFE Incorrect on what, that high compression and boost is a bad combination. If i'm incorrect then why even make pistons for lower compression builds, meh! blocking your channel.

@@mooosestang bye. Lmao.

That would just be less timing in the tune and not necessarily I had the same thing happened to my car and I had the timing pretty low since it was a daily driver.

@@richie2dicks468 I'm running a pulley and tune, on a 2010 GT500 if that changes anything. My opinion is it's a safer margin to run the 91 tune on 93 octane but I'm looking for the correct answer versus my opinion.

@@Twobarpsi the only difference between a “91” tune and a “93” tune is the timing. Less octane less timing. It’s not complicated.

@@richie2dicks468 yeah no shit Sherlock...less timing = less chance of detonation, want to hear it from Alex if it's safer.

@@Twobarpsi if it’s no shit then why do you have to hear it from him if you just answered your own question? You’re the guy in the tuning que he talks about when he wants to beat his head against the wall.

It's not a valve. Exain the smoke If it's a valve

Hey man how miles was on the engine before it went and was it boosted?

@@johnsentinel9008 yea it was boosted since around 38k miles. 8psi I only have 93 in my area so no e85 and it still had stock exhaust. I think 1 of the 2 was probably the cause. It took a few hard limiter hits from 3rd gear lockout that maybe didn’t help. Somewhere in the 80k mile range it started having noticeable blow by and the temps would run hotter during summer. Drove it about 1.5 years like that and this spring around March it let go and blue by started fouling plug on #8. Did compression check and she’s gone. That was around 92k miles. I would have gotten the bottom and replaced right away but I’ve been holding off because I’m going to do the exhaust and a new clutch while it’s apart. Also get it retuned. Altogether it was pretty much going to max out my budget so I’ve been trying to put some more cash in the pot before I start. every project tends to run over budget.

No

This is not a how to channel. Learn. Like we all did. By doing.

@@YDBT4LIFE lol exactly what I’ve been doing I’ve done compression test on my bmw no problem. I’ve tired m14 and m16 and m18. Doesn’t matter a how to channel would be more knowledge for someone who needs help. No need to get butt hurt over a comment. Lol

@@1morebmw197 says the guy butthurt that no one tells him exactly what size is used on a coyote

@@YDBT4LIFE not butt hurt just simple stating something. That obviously you took offense too.

@@1morebmw197 no. Just another whiner on RU-vid. I am petty and reply to all whiny RU-vid comments wanting specific details available to anyone that does a little research.

That is not for damaged engines

700 or so. There's a video on it

Alejandro Flores I’m sure I’ve seen it just couldn’t remember

What’s a gear driven vortech. You talking about a v7 jtb?

@@pierbicchi7328 it’s directly mounted to the crank and not driven by the belt. I think only certain head units are compatible.

I was thinking the same

I find disconnecting injectors much easier. I have to handle a camera. Talk...hit button to start car...narrate.... zoom in... Disconnect injectors...done

@@YDBT4LIFE fair enough just trying to be helpful. You pass along a lot of info, just thought I’d do the same.

@@travisc.3881 I really do appreciate it I hope I'm not coming across as if I don't appreciate it I'm just giving you my thought process LOL

@@YDBT4LIFE no worries, no offense taken at all. I get it, it’s a one man show and you only got two hands. Whatever works easiest for ya. Hopefully you get your white car taken care of. Good videos 👍

I'm convinced my cats got clogged from too much octane booster. Vp purple label actually says it's not safe for cats.

Gen 2s seem to be more tolerant.

Some people swear by it...the plugs say a different story. lol

🤣🤣 nobody needs that kind of negativity in their life

@@snowman2834 😂😂😂

Wrong. Starter need a dedicated E85 tune
