Thanks for posting! God bless people like yourself to take the time document and film this stuff to educate others. I just purchased a 91 Formula with 350 TPI and am enjoying getting under the hood and understanding how all this stuff works and such. Always wanted one of these back in the day, and now I have one.
@@delfmeek that's the one! I was VERY close to pulling the trigger on it when I saw it listed for sale. I had to check myself because I knew I wouldn't be able to give it the attention it deserved. I am glad to see it found a good home. I am sure you will have a blast with it. Let me know if you ever decide to sell it😁
@@VetteSource Will Do! It's actually in transit on it's way here. I'm in Oklahoma and it's making quite the long voyage here. It should be here next week. I'll see if I can get a video posted when it arrives. I had a 1991 firebird (non-formula) equipped exactly like it back when I was younger, and always wanted a Formula version. I personally think these third gen Firebirds/Camaros are a bit undervalued
@@delfmeek that's for sure. They are incredible bargains compared to the IROC-Z's and look just a bit better in my opinion. You will have a blast with it. Looking forward to seeing some of the vids once you get it.👍
A few things: they are throttle de-icer hoses because in northern states the throttle plates would freeze and stick. The stock injectors on a 5.7 TPI were 24 lb injectors. The vacuum port on the throttle body is actually port vacuum used for the EGR valve. If you hook up the EGR valve to one of those rear manifold vacuum ports, as you stated, it will kill the engine at idle, because it is supposed to be opened by port vacuum not manifold vacuum. The lower runner bolts are always torn up because the valve covers are in the way when on the car, so the angle to reach them is sharp, a wobble extension usually helps to keep you from stripping them. FWIW
Excellent Footage and great explanation of parts. Just purchased my dream IROC which houses a 305 TPI. My service engine light is on and assume its the EGR mechanism. I now know where it is thanks to you
Hey Jeff, I have a 90 vett. Darn near drove me nuts with EGR issues. Yeah, yours is a 305 TPI and mines a 350. But the EGR valve and vacuum lines run near the same. I went through 3 new EGR's that couldn't hold vacuum psi. Two of them Delco and one standard. If you're going to remove and replace, do yourself a favor and Check that it will hold 15 to 20 psi. before install. Save the old parts just in case. My vett has a solenoid Vacuum that runs to the EGR that attaches to the back bolt on the thermostat cover. Another new part that failed. It had a crack. Ended up reusing the old one to correct that. I also found that the plastic vac. line fittings, along with the hoses turn to rubbish after 30+ years. Had a cracked Y fitting that ran to that solenoid. had to smoke test to find that one. Runs like a champ now, but getting there was a pain. Good luck with yours. Hope this helps.
Thanks for the information. I have heard the problem goes deeper than a New EGR and you just confirmed that because new EGR did failed to eliminate the SERVICE ENGINE Light. I have a mechanic neighbor who has an OBD1 reader (who would of thought) and he loves my car as much as I do! He is assisting me in trying to find the issues. @@tonysteppan8495
I know this is an older video, however, it is full of great information on how to dissemble the TPI. You made it look easy, I like the fact that the top comes off exposing the EGR etc. without taking it all apart. The con of this video is the shaky camera, man if your prone to motion sickness you don't want to watch it to closely. You need a camera stand for us guys that suffer from motion sickness. Thanks form the great information.
I used to be a Camaro person, but became a Foxbody person after being introduced to the 5.0. I've always wondered how the TPFI system worked, I appreciate the info. That said, man I absolutely am convinced the Foxbody Mustang is wayyyyy easier to work on and break down after watching this.
Glad you enjoyed it. I like the 5.0 too. I have a MKVII I gave to my son and it's very simple to work on. The TPI, while awesome to look at is like trying to put together a 5000 piece jigsaw puzzle.
It's a good day when you come across an L98 TPI car. The F bodies didn't seem to make it this far compared to all the fox body Mustangs you still come across.
That's for sure. I feel fortunate to have 2 TPI cars that are mostly original. I think the complexity of the TPI intake is how many of them have been lost to time. Many owners just ditched the intake and put a carburetor on them when they began to experience problems.
I disconnect the fuel lines at the sending unit to stop the eternal drip, but those lines are harder to access on the f-bodies . I would recommend removing the fuel cap, and disconnecting at the filter. That should do the trick.
man i want to thank yu for your videos i was like if i don't find anything like this ill make some videos, good info my 85 corvette has had a knocking noise for over two years and i think it may be in the lifters but i didn't want to tackle taking this aart until now i seen your stuff. now it looks fun lol other than that it run pretty good in limp mode but rough with no codes in closed loop i tell you went the car runs right its quick and fun so i want to keep it. changed the maf today still runs like a vacuum leak unless i unplug the maf or burn off module which either one will put it in limp mode
thanks man, glad to share the knowledge among my fellow gearheads. Sounds like your car just needs some top end work to start. You can also check to make sure you are not seeing low oil pressure at idle when hot. One other trick is a lower end knock will sound different depending on where the problem is. With rod bearings it will be a light tapping sound that accelerates with engine RPM. With a main bearing it will be a deeper heavier knock that is very distinctive. Thanks again for watching buddy, have a good one.
Great!, glad you enjoyed it. Be sure to watch out for the continuation of this tear down series as I do a top end intake job o the Yellow Gold Formula 350 - ua-cam.com/play/PLAM-V1w3acphkZJyLroCKcyLO9GzqR6q4.html Thanks for watching!
Great video I have this engine I have white smoke coming from back and when cold starts my motor sounds like it wants to shut down? Then kicks back up. I know it's not normal for the engine to do that but don't know where to start fixing issue?
Glad you enjoyed it. My first thought would be a fuel injector that's hanging up on you. You can pull the plugs to see if they're wet or fouled. The fuel rail can also be pulled up to see what the injector spray pattern looks like, but that requires a bit of teardown and caution when opening the fuel system in that manner on a TPI. Let me know how it goes👍.
I’m not a mechanic and have a question in regards to a tpi system. Car has a lot of miles don’t know if engine was ever rebuilt. However car is running very rich . Also having a lot of issues with idling . Would it make sense to take apart the tpi and give it a clean up new gaskets get valve and clean injectors . Please excuse my ignorance as I said I’m not a mechanic just thinking if things that I might do to help make it run better
Hi Shannon, before you tear into it, have you hooked the car up to a scanner to see if there are any trouble codes in the ECM? With a rich idle condition, the air/fuel ratio of 14.7 to 1 is not being met, and in many cases is being caused by one of the primary air intake sensors such as the Mass Air Flow or Idle Air Control. Also, the injector internal seals could also have failed and will dump too much fuel into the cylinders. Even a faulty ECM can cause the problem you are describing, so it's best to start there first. Let me know what you find out👍.
I have wondered how to tell the f-body and the vette apart. The distributor cover is also different. Plastic on the f-body and magnesium on the Corvette.
Exactly. I have always wondered at the difference in materials between the two and how that decision was made. My guess is the heat produced under the hood of the Corvette might cause the plastic units to melt. Thanks for watching👍
@@VetteSource I agree but also think it's for protection as well. On a C4 there is a relief on underside of hood/ front clip that rests very close when shut
@@VetteSource I agree but also think it's for protection as well. On a C4 there is a relief on underside of hood/ front clip that rests very close when shut
@@hayleybmadiggunter6798 good point. There is definitely quite a bit of cowl shake on the early C4's so that may have been a way to protect the distributor from being damaged. Never thought of that before.
Do you know where I can get that egr vacuum line as well as the vacuum line for the fuel pressure regulator please? Mine where burnt due to sun damage and need to replace them
I think it's Dorman that makes a vacuum line repair kit for the 80's GM and Ford cars that used this style of tubing. I believe the brand name is Mighty Vac Line Repair Kit or something to that effect. I would check the HELP section of your local auto parts store to see if they stock it.
Hey Brian! Great video!!! To remove the Intake Air Temperature sensor, do you have to take the plenum off, or can it be removed with the plenum attached?
Great explanation! Im getting into a small block 400 that has a Corvette TPI married to it. I didn't build the motor so i dont know what's been done to it but your explanation raises a question in my mind. This motor was built for a drag car. They would have had to put larger injectors in this thing to make it work with a 400 ci motor correct?
Possibly so, it depends on the cam/intake port/combustion chamber size. Even with heavily modified TPI topped motors, most of the time you can get away with 24lb/hr injectors. It is when you get into turbocharged/blown/nitrous motors that you need to begin looking at larger injectors. Thanks for watching!
Not sure why it was like that. This was from an engine I had torn down many moons back. They may have been trying a custom setting to see how it would work.
@@VetteSource I'm interested because the previous owner had set mine like that as well and although mine runs well, it usually needs some throttle to start. You think it may have to do with the tps setting?
Yea, that usually the first thing you'll notice is throttle needed to start with it being set outside of the factory specified limits. I seem to remember people setting them like back in the day, but for the life of me I can't remember what the rational was for it.
@@VetteSource thanks for the help. I'll adjust it to spec and see how it does. Btw, your teardown videos are very educational, if you ever do a step by step on how to measure/adjust timing on a tpi, I think it would be really helpful to guys learning these engines.
That's a good idea and is on my video to do list. Once I find enough time to finish getting the top end of my Formula 350 reassembled I'll be going through the steps required to dial it in. Let me know how it turns out with your car👍.
Hi Brian. Your more than helpful. But we have an issue with getting the last bolt out by the drivers side on the intake tube. The metal break vacuum hose is in the way. We can't get to the clamp to get that off. Any ideas.
@@BSmith-md9wi are you trying to get the rear bolt that faces inward, or the rear bolt that comes from the inside facing towards the outside of the engine.
Yep, everything on the intakes is the same with the exception of the fuel injectors. As long as you switch over to the 22 lb/hr injectors you should be fine. Thanks for watching👍
Galvanized corossion... It's not good to heat aluminum up as it changes the chemical structure, allows intergranular corossion to occur too. TBI is not a half carburetor. I would replace all of those torx bolts with hex bolts and use a teflon washer or switch to an al based bolt... TPI is basically a tunnel ram that LS engines can have

VetteSource I just watched your TPI field strip what a great tutorial if you could do a vacuum line tutorial that would be great!!! Thanks for your help. I have a 1991 camaro 305 that I bought as a project and found that the previous owner did a lot of deleting.
Do you happen to know how strong the block is? I have one its been bored 40 over cant find anything on this block just dont wanna spend the money if the block is weak
The 350 castings from this generation are still pretty stout. 40 over isn't bad, but I would inquire why they chose to go with that size overbore versus a 30 over which is usually the standard.
