I commend you for not deleting the A/C in the name of making power. Comfort is always key.
I never understood that. Sweat balls just to make an extra 2hp
Yea delete 20lbs thats causes 0 engine drag at WOT just to sweat and have wind noise in the summer, never made sense to me and whats worse most people throw it away too.
when I bought the car it was deleted. I’m the one that put it all back in the car haha. I just need a couple more things to charge it
@@Thecraig909 how much of it was junkyard sourced? Never had a good compressor from the junkyard.
Craig don't worry about making mistakes it's how we learn stuff. And as for being "perfect" nobody is but I have worked some people who thought that they were.
Sounds like you're sucking oil thru the intake on decel., under max vacuum. Maybe pcv, or the breather.
I think it's a better idea to paint the whole car. I know you have little time on your hands to work on your cars but it'll be worth it in the long run. Otherwise after you paint the front you'll think it looks great but the back will look funky with all the scratches. Just a thought. I'm always happy to see your progress btw. Keep up the great work. :)
Absolutely. Any paint and body shop would tell him the same. I would, too. I've worked in a few body shops.
I agree
First thought would be the valve stem seals, Maybe a stuck open pcv valve sucking in oil, could contribute to it wanting to shut off when it's cold if it's stuck open too (vacuum leak) run a catch can too that way your octane rating doesn't lower burning off oil
Tons of respect Craig. Most would not admit what they do or didn't do. I've been twisting wrenches and bending metal on my projects for 40+ more years than you, still learn something new every day. Keep up the work. Love following your videos and progress. 👍👍👍
Always a good video with the Foxbody in it!🤘
Im 42, just now geetin back in the foxbody scence after 20 plus years out and im making mistakes but im learning and thats what matters. Love your channel 👍🏼
Nice find on the timing mistake back to basics when things don't seem right. I'm surprised the roller rockers don't hit the valve covers?
Check egr tube back of motor, clean iat and throttle body. Seafoam through brake line. Then mass air sensor. Verify no vacuum leaks or burnt ignition parts. Should be good
Great video. Really enjoyed it
Nice clean up on the top end and a great episode - hardly anything failed completely to work (except that broken bolt of course)..... she is getting to the point where you'll be tempted to sell her and move on to another pile ;)
Good stuff Craig love the Mustang content.
Your channel rocks, keep up the great engine mechanical work.
In the back of the intake where your pcv valve is. There should be a mesh screen slug/breather element that goes under the pcv valve. It could have been left out on the rebuild. I put a catchcan between my pvc and intake to evite oil getting in the intake. Also make sure the valve over is still baffled where is. COnnected to throttle body
Eureka, that's it. Rebuilding a 302 87 F-150 and needed an idea for valve cover and intake color. Off color gold it is. Thanks! I enjoy all your projects.
If you do want a 75mm throttle body do not go with BBK. They whistle so damn loud. I have one and it whistled so I recommend a Accufab throttle body
Thanks for the tip! I’ll look at another one
I feel your pain, picked up a 93 early last yr with that same issue, apparently if you round over the iac hole itll end that. I havent gotten around to trying it yet but, it is quite annoying for sure.
@@nunya2814 It caused most of my issues as well, idle hang, sticky throttle etc. i replaced it with an explorer one and it worked ever since. It also took a little power out of it as well. WOT it was an animal but It didn’t drive well
@@Nitro-fu7rv havent had any of those issues on mine, but im not a fan of bbk other than their headers, fpr nothing but problems with em. Keep my fingers crossed i dont develop any of those other issues you were having.
@@nunya2814 I found out what happens is the spring for the butterfly binds so it causes the “sticky” throttle. It looked old and there’s old school mods on it so I’m guessing there’s some miles on it
My 88 lx is in the shop now getting black paint. He sprayed the front bumper and wing today turned out pretty good. Cant wait till its finished ive bought new quarter windows and 10 piece side moulding for mine
good video! You know pestle mount rockers torque down they do not have adjustment they torque to 22-25ft pounds.
I was thinking the same thing.
Was just gonna say theyre non adjustable. Only way to adjust them if the pushrod length is proper, is with shims.
@@coupestanger90 yea exactly
I would double check pushrod length. If the previous owner upgraded springs for a cam, who knows if he put the stock pushrods back in??
the 1/4-1/2 turn trick for pedestal rockers is to ensure proper preload on the lifters. If yours torque down before 1/4 or after 3/4 turns, then you need a longer pushrod or shims respectively
Like how the v covers came out . Looking forward to see how it runs. It's funny how the things your doing to the fox I have to do to mine. Do you ever talk TJ Hunt would be cool to see you guys together. Keep up the great work on your videos
im having the same issue with my fox and sometimes it backfires thru the intake, im sure it was the issue with your timing. also i found my fuel pump wiring to be corroded and my fuel pump was running weak. winter in michigan so haven't been able to get it out to see how its running now... but its so funny your car starts up just like mine where it dies a couple times, i got a top end build on my 302 and a lot of the same upgrades. your car reminds me so much of mine!
Looking good!
Wow this car has come a long long way.
Nice work dude.
Bro no worries I just wanted to make sure you knew about it, not everyone does car sounds great love the videos on it
Omg 5 degrees I bet it feels so much better now! I just did my distributor and set mine to 14
check where the plug wires are at on the cap, there should be a molded number 1 on the cap and that is where the number one plug wire HAS to be. the fuel injectors are sequential and timed off the wheel inside the distributor and if your plug wires are not in the correct spot you will be spraying fuel at a closed intake valve and can cause the pops at lower rpm as the fuel doesnt go to the correct cylinder.
Your editing skills are improving.
Mine run like urs did until i put new O2 sensors and discovered a cracked vaccum hose under the intake. Now it runs like new but its incredible the similarities in both cars
I always use umbrella type valve seals if possible
Another great video
Can’t wait to see you ripping on it now!
I have missed the rear sump before. LOL, sounds good
Maybe add a catch can to at least keep the intake from clogging up with oil deposits again. You’ll just have to remember to empty it often enough. Also cross check Ford throttle bodies because some are at least 70mm from the factory on larger engines. You may be able to upgrade that at the junk yard for a lot less than a new Accufab. (Unless they want to sponsor you of course)
There's a 91 in the Chula Vista yard with a clean cowl
put some Lucas in it, in the summer run thicker oil (for example 10W-40 instead of 10W-30). your latest repair should solve the popping and backfire issues, please do a follow up video and let us know.
becareful but try a spray bottle with fuel around the intake manifold if the revs pick up leaky gasket, just a sugestion, our 5.0 in australia are roller rockers
I work at CarMax in the buyers department we buy any car running or not but you should definitely bring it in cause I’d be interested in what they offer you could offer more than you think
Good afternoon Craig hope you have a great day
Oil Burning Rings or valve guides !
I don’t know how you manage. So many cars, so many ongoing projects, you must be overwhelmed. If it was me, I would focus on one car/truck and finish it 100% and only then move on to the next. It’s cool you’re spending time on the Mustang, as it’s your only ‘decent’ car (meaning it has A/C, and is usable as a daily). Your other vehicles are great, but everybody needs 1 reliable car/bike/truck
My fox use to burn shit ton of oil and buddy of mine added in a different baffle in the lower intake and it helped stopped smoking running the 93 cobra upper and lower believe it’s the china upper and lower tho
Ignition coil. Same thing happened to mine 2 summers ago.
how are the timing chain and the cam lobes doing, have you boroscope them?
Honestly probably could hang with a coyote your 302 is probably make 285hp at the tires your is around 2900lbs newer mustang are 3800-4500lbs if I remember correctly gen 1 coyote makes around 400 flywheel hp
What size tires are on the back of your foxbody?
Craig. What do you know about deleting the egr and smog?
Check your egr system it mite be stuck.open.abit when its not suspose to be so its lean causing the missfire
what is that wire plugged into the intake tube on the way up (not the MAF)?
If you work on heads look at up grading to gt-40 or gt-40p head and intake.
Why? The trick flow kit cost the same and makes 100 more horsepower. GT 40 is really weak. Trick flow looks better and makes 5 times more power than GT 40. Fact. He already has the intake btw.
its called base circle of the cam
A good day at the office 👍!.
What camera are you using??
I don't know why it's burning oil but the engine is running lean and maybe try getting a tune for it but the oil burning problem you're going to have to try to figure out the basic
ALSO be careful with the clearance of those roller rockers with stock valve covers! i heard a lot of noise when you started it back up after getting it all back together. i know they sell a little bit taller valve covers for roller rocker clearance but it requires you to add a spacer to your upper intake.
That would only really be a problem with stud mount rockers and poly locks. The noise is most likely some lifters that bled down while he was working on it.
You can certainly get away with it, but read some of the forums and a lot of people have had to either remove the oil baffle or grind out some of the inner ribbing of the stock valve cover.
What exhaust on the car ?
I feel really silly asking this , Did you check to see if the throttle body opens to 90 degrees when the gas peddle is pushed to the floor ? I ask this because , I found that to be true on mine .
Good work kid but why is the Galaxie on hold???!!
I had a similar issue, turned out to be a cracked lower intake manifold.
Havent seen you address it in your videos but have you ever cleaned the PCV screen in the back of the intake under the pcv valve?? If plugged up then you will get no flow thru the PCV and will cause smoking and excess oil in the intake
I think you’re right. I left this same comment on the last video and even posted a link to a video showing the pvc screen. This was one of the first issues I had to deal with when I got my first foxbody back in 1997 when I was 16. Unfortunately I don’t think he checks the comments.
@@slow5oh89 i rarely ever see him respond to any comments but like most.....comment like and subscribe its greatly appreciated....even though they dont respond🤷🏻♂️🤷🏻♂️ oh well mine dont smoke so whatever.
For backfire issues
Love your videos and the car. but that car will not hang with a coyote lol keep upgrading the car looking good
Craig why don't you just wrap the whole car gloss black ? Keep up the great upgrades and PLEASE fix that cowl soon lol.that would be a night and day difference.
it sounds like you may have a some slop in your timing chain.
I mean ik you made a mistake but to at least figure it out and have tons more power is pretty sick
Hang with a coyote? Come on Craig lol jk the car is coming together nicely gotta love a foxbody
Is the baffle still under the oil fill tube on your passenger side valve cover? If the baffle is gone you can draw a lot of oil through the vent tube that connects to the throttle body.
And LOL on the timing! I bet she woke up quite a bit after that! I think you said in one of your videos that the car has GT40 heads and an E cam? Obviously it has an Explorer intake which flow almost identically to the tubular GT 40 or Cobra intake. The roller rockers were a good addition to that setup. My engine is almost identical and it's really a decent combo. 260-275 at the rear wheels. Get a solid tune on it yet and you should be quite happy with it.
Also hopefully some aluminum anti seize on thoes intake bolts . Lol
" Gonna go little by little ' til I get it out". That's what SHE said. 😆
you could have spent that time and money on one of those galaxie's
catch can setup
Try a can of restore might help
Its a fuel issue. Check your fuel mixture.
Timing chain slack.
👍
You have bolt down rockers. There is no adjustment.
Dude next time do the oil leak fix on your mustang
As a garage door guy, I have to say that it is bugging the crap out of me that the bottom 2 panels of your door are insulated and the top 2 are not!!!
😆😆😆
Oil catch can
Always love the videos!! But I can promise you that it will not hang with a coyote at least not mine I have pretty much the same fox build and my coyote would spank it!! Lol either way I love what u do keep it up!!💯
Get accufab throttle body bbk and other brands make a horrible sound
Because it's a Ford

I cannot believe you just said you could keep up with a coyote.... I love your videos , but I think the paint can fumes got to you at the end of the video for you to think that. No way your car is pushing 400+ hp.
We all make mistakes, Even I had a ford once! LOL
It aint the valves. You have a fueling issue. Your engine uses 02 sensors, why dont you measure them when running. 0 volts is lean, 1volt is rich, pretty simple. your valve nonsense is just that. the burning oil is from the guides NOT THE SEALS, the seals allow oil to lube the guides, the guides cause the excessive oil. Why dont you have caps on the compressor ports? do you plan to not have a/c? Timing needs to be 10BTDC, not 15.
you can have more timing advance with top end modifications. i run 16 degrees base timing on my fox.
@@tabletop45 you modify timing in the ECM, you leave base at 10
Put a small block chevy motor in it
