Seriously, who are these people down voting this video? I don't think this video could have been done any better. It's one of the best automotive tutorials I've seen on KZbin. It makes this job basically foolproof.

Couldn't have found this at a better time. Going through replacing my water pump on my 94 Firebird and have been putting off taking care of the oil leak I've got in the intake manifold as well. Need to do exactly this and it's a huge help man! Thanks

Perfect timing nwale! Thanks for watching

Thank you for the no BS video. I am ordering gaskets today, hopefully no more burnt oil smell. Thanks again.

Thanks for taking the time to watch and comment.

[@moodberry]

What I LOVE about your videos are two things. First, your photography is sharp and focused. So many other YT videos are out of focus and they don't actually focus on the thing they are trying to point out. You also POINT to the actual thing you are discussing. And secondly, you talk about the part instead of just saying "And that there is the 22-13109998 part. You tell what is it's function and how it relates to other things. Keep doing things that way please.

[@ozzstars_cars]

Thanks for your comment! I intend to keep doing what I'm doing. I appreciate the positive feedback. -Glen (Ozz)

[@jhobbs1824]

Thank you for making this clear and concise video. I turned it into a PDF (for my own purposes) so I could place it in a binder for my 1992 Corvette LT1. I'm a little older now and need this form of aid to keep me on the right track. I'll probably never give up working on cars as it keeps me active. Your technique of explaining what your going to to, then doing it works well with my cutting and pasting technique. My document turned out pretty good (for my level of skills). I'll have to be looking over your channel now for other videos that have to deal with C4 maintenance and repair. These cars are great looking but I hate to say it, cheaply made. The things that they experience should never happen to someone who paid the full price for this car. I have the original build ticket for mine. Wow. I'm glad I didn't pay full price. It would have been a let down to have the problems that current owner's have to go through. Shocks, Opti, EGR, Water-pumps, etc. If this was my first Chevy, it would have been my last Chevy. I've only had one other car that was as poorly made and that was a 1990 Jaguar XJS. Over engineered to fail. Anyway, it was a pleasure to see someone work on a car with care using proper techniques. Thanks...Jack

[@ozzstars_cars]

Thanks for the comment Jack. I'd be interested to see how the PDF file is put together, sounds like an easy way to refer to the service information. GM is pretty much junk. I paid big money for my '18 Grand Sport brand new and there issues that should not have failed such as defective belt tensioner, torque converter slip, and so forth. My email is [e-mail] if you don't mind sharing your PDF work with me, otherwise no problem. Take care Jack!

[@moodberry]

​@@ozzstars_cars The thing about GM is that yes, they are "junk", but their engines are not. I own a 92 Corvette manual and accurate info about them is almost non-existent. GM does things their way, and it works to sell cars. One thing that REALLY makes me mad is the cheap materials for their trim and interiors. And that's for ALL their cars, including even Cadillac. Lots of bling but low quality when it comes to durability. They do things like chroming plastic parts. What's with that? Anyway, I own two GM cars now. The Vette and a Colorado truck. Prior to this was 45 years ago when I took my bride on our honeymoon in a Chevy truck. Even then it wasn't built all that well. I can honestly say that although hard to work on, their drive train is not that bad and is intuitive. Some things are REALLY smart. But the majority is not all that good. It lasts just long enough to last through the warranty.

Dude, wish u lived close to me so I could bring my Corvette to u and pay u to let me watch and help u fix it. I'm scared of a task like this, but now at least I do have a general idea of how to do it if I ever got the balls too. Mine is a 1991 C4 L98 and it's leaking either oil or transmission fluid badly. It's been parked in my garage and hasn't been driven in years, but I've finally got the time and the money to be able to work on it and I'm trying to watch, learn and then go apply to mine. You've been very helpful so far and by far the most in depth as far as the sequences go. I have never worked on an automobile til now, and I'm learning a lot, but it is quite overwhelming sometimes. Thanks for the videos tho. I've watched all of them on C4's numerous times

[@ozzstars_cars]

KZbin makes it easy to learn how to do it if you watch the right vid that has the correct info. I have been working on cars for a lonnnnnng time way back when you had to read a book or learn from someone showing/telling you in person. You have the ammunition to get it done....take notes, take your time and stay determined.

Great video....good information. I am totally an amateur when it comes to working on my car. I have a 1996 with an LT4 motor. Always interesting to see how things work. LT motors are quite unique for sure. I have only done basic maintenance on my fluids. I haven't yet seen a good video on flushing the power steering fluid yet. This year I did decide to install a short shifter and did the entire installation myself. I was a bit of a project but it went just fine. Thanks for taking the time to do this video. It is very helpful for guys like me.

[@ozzstars_cars]

Thanks for the kind words Russell. It takes a lot of time to film and edit but all worth it when I can help teach someone something new. I did a power steering flush on this '93 Vette but never filmed it...maybe next time I guess.

[@eaglerider94]

Try a 50/50 mixture of acetone & ATF fluid in a small bottle with a dropper. Let it soak in @ 10 minutes. One something like the tube off the exhaust manifold or anything exposed to extreme heat, allowing it to penetrate overnight is best. Best frozen bolt remover I've even used which has never failed me!

[@ozzstars_cars]

I've heard of it but never tried it.

[@eaglerider94]

​@@ozzstars_cars The acetone which is extremely fine is the carrying agent which allows the ATF to really penetrate. Just finished your 2nd intake video. Very well done. Done almost everything myself on this Vette except the clutch. Almost attempted it but really glad I sent it out to a Corvette specialist. Connected him with Dr ZF in Arizona who gave him proper tips on reinstalling a ZF tranny as they aren't just bolt on.

[@spinson344]

Nice video. Thanks for sharing. My 30th Anniversary Z28 is leaking from the rear of the intake manifold like you commented. I'll be doing this project in a few days. Did my Optispark, cam seal, and water pump seal today. They were leaking too and causing the opti to miss. I wish my Camaro had the room your Vette has at the rear of intake. All of the rear work will be done blind.

[@ozzstars_cars]

If your Camaro has the oil pressure sensor unit located on the top back of the engine make sure to check it's not leaking. Thanks for commenting Spinson.

Great video. I bought a 1997 Chevy Camaro SS LT1 in November. I noticed it has an oil leak but haven't looked under the car yet to find where it's coming from. It is leaking from the rear of the motor somewhere. Watching this video makes me think it is coming from the intake manifold. I may attempt to do the job myself now watching this helpful video. I am just waiting for a steady 30-40 degree weather to take a look. Thanks for the video.

[@ozzstars_cars]

Thanks Udlooz, glad the video was helpful. Best way to check is with a small observation mirror back there and also getting under the car. If the oil is leaking up high on the back of the motor it's a good chance its the intake manifold leaking, also check the oil pressure sensor/sender, they are known to leak oil. Good luck, you can fix it! - Ozz

[@rusmac2017Z]

One question.....how do I know if I have a wheel bearing that is bad or nearly bad. I have done some research and from what I can tell if you have the car in the air with the tires on you should have almost no play when you try and wiggle the tire up and down. Is this correct? Please advise. Thanks....Russell

[@ozzstars_cars]

Yes, if there is excessive play the bearing may be bad or need to have the proper preload set. Be sure its not worn out ball joints. If it is very wobbly then most likely there is bearing failure. Many times that will NOT be the case though when the bearing is bad. While the tire is off the ground, spin the wheel and hold a suspension part with your free hand (like a shock or strut), feel for excessive vibration and listen for abnormal noise. Wheel bearing diagnosis can often be tricky to find.. you can hear it going down the road at 30-40+ mph it will "howl" and make a loud annoying sound. Hope that helps you out Russ

[@timbucker]

So if you have to remove the throttle body, is there really a need to drain the coolant and remove the hoses and other things attached to it?

[@ozzstars_cars]

You don't have to drain the anti-freeze or remove the throttle body coolant hoses if you keep them attached and just separate the TB from the intake. I wanted to clean the TB out completely from both sides and did not want to chance any liquid getting into the Optispark which is under the throttle body. Once that happens kiss it goodbye in a short period of time and plan on a few more hours to replace it.

[@rappini2201]

I've been wanting to change my intake gasket for years on my 92. I have a small leak that I can see that ends up at the oil pan plug.

[@richparisi2600]

How often does an LT1 leak through the sides of the manifold as opposed to the rear.? I believe this is happening on my 94. Looks damp on the passenger side, to the inside where you would add engine oil. Slight dripping onto the garage floor. Btw... I just completed new shocks,front and rear and brakes& rotors all around using your other videos as tutorials. All came out perfect!! Thanks.

[@ozzstars_cars]

Sometimes a leak like you described can be cured by properly torquing the intake manifold bolts. They can loosen over time. If the intake was removed at one time and the bolts did not have thread sealant applied the oil can wick out. I would say the rear and front leak is most common. Also inspect the valve cover gaskets for proper sealing. Good to know the shock vids helped you out. Thanks for your comment and take it easy. -Glen

[@richparisi2600]

Ok thanks for the reply. I was thinking valve cover gaskets in addition as well. Might as well inspect the pcv valve too while I'm in there. Looks like a project for next weekend. Always value your input. Later.

[@anathomas1274]

I am working on an issue with my 94 LT1. I got coolant in my oil Was hoping it had something to do with intake. The only thing I see that could cause it from the intake maybe those large plug holes in the water chambers of the underside of intake. Do you have a take on this problem?

[@ozzstars_cars]

The intake on the LT1 of this generation does not have any coolant flowing through it. You need to do a compression test to find where the issue is....most likely a bad head gasket or cracked cylinder head. Has the car been overheated? Head gasket issues are not that common with the LT1, they can often get up to 235 degrees with no issue, but anything over that is suspect. Good luck Ana

did it run noticibley different after the repair? I have mine getting worked on now. I have heads and cam and full long tube exhaust with every Bolton possible and mine had bad power under 2k rpm and loud miss fires between shifts due to vacuum leak

[@ozzstars_cars]

Besides no more oil dripping along the back of the engine it did run better. One less vacuum leak and on occasion i would see a puff of blue smoke out the exhaust pipe. All that is gone now. You should notice a real nice difference when you get your car back, as long as it was done correctly. Enjoy it

[@ryans.6841]

I got Chevy's master mechanic hooking me up. port and polished intake to go with it so I'm excited. I've had it about 6months and drive it about three hours lol. I can't wait dude!

Did you bleed the system when you were filling the coolant?

[@ozzstars_cars]

Yes, that is important.

[@strider99]

I was watching your videos 1 and 2 on the manifold gasket replacement for the LT1 Corvette C$. Two questions. 1. I am pretty handy and have all of the right tools. I have a 1990 Corvette and it is leaking antifreeze and very small amounts of oil. I could see the antifreeze on the manifold. Is my 1990 close enough where your video should work for me? 2. you did not mention how you cleaned the china walls. I can see what look like buff marks on the China Wall. Can you elaborate exactly how you cleaned it? I know you had to use a scraper, but you used something else as well, what?

[@ozzstars_cars]

Your '90 Corvette L98 has a different engine design but does have a 350 cubic inch block so technically the china wall is pretty much the same. 1992 was the first year for the LT1 in a Corvette and used through 1996. I never use a buffing wheel to clean gasket surfaces, even though on steel/cast iron it is acceptable. I use a razor blade scraper and then clean up with brake cleaner and a clean cloth. Some extra fine grade sandpaper cleanup by hand if the grime is really difficult to remove. I work by the hour not flat rate so I take my time getting the job done ;-) Hope that helps you out Gerry, take it Easy -Ozz

[@strider99]

Yes, this helps, thank you for the reply.

[@aaroncameronhss8994]

im looking at replacing my intake with an Air Gapped version … but I have the camaro and the windshield goes over the motor quiet a ways so im a little nervous about it

[@ozzstars_cars]

Don't get in to deep.

[@aaroncameronhss8994]

that's what im thinking but gotta get the oil leak fixed, its out of the back, its leaking down the back of the block on the passanger side. gets all over my manifolds and stinks something awful... I did an intake on a suburban, but an engine bay you can sit in vs a camaro that you can barely squeeze your hand in …. big difference there..

[@peteesramchannel416disalvo9]

hi I have leak back there to on my 95 lt1 can it sometimes just be the oil pressure senders alone, and can they be replaced without all that work , and how would I know if its just the oil senders and not the head gaskets. please help.

[@ozzstars_cars]

use an inspection mirror and flashlight to look for oil dripping out of the sensor(s). It is possible to replace the sensors w/o removing the intake.

[@peteesramchannel416disalvo9]

ok thanks so much your videos are great

[@ozzstars_cars]

[@gustavosalazar6316]

Would this vidoes information be the same for my 1994 chevy impala ss with a LT1 5.7 and what are the intake manifold torque specs?

[@ozzstars_cars]

Yes it should be very similiar but with tighter access near the firewall. Intake manifold bolt torque specs, first tightening pass (8Nm) 71 lb in, second pass (48Nm) 35 lb. Ft.

[@xtransam9970]

Great job well done

[@ozzstars_cars]

Thank you

[@DoityourselfautorepairVetteman]

I plan on doing the exact same thing to my 96 Corvette. I plan on ordering the same gasket kit FEL-PRO MS95580 along with the Permatex 25229. I do have a small oil leak in the rear of the intake and hoping it is the old bead of silicone that has failed. Is there any benefit to cleaning the intake manifold? Is there anything I am missing as far as the gaskets go? I really appreciate your video....it's the best I found. Thanks so much.

[@ozzstars_cars]

Cleaning the outside of the intake will make it look pretty. Unless there is major carbon build up inside the intake that's useless time spent. Watch both parts of the video again and it will be downhill from there when you do the job. Good luck, thanks for the comment and subscribe for more if you haven't already!

[@DoityourselfautorepairVetteman]

Thanks so much Glen, I have had the tb off in the past just to clean and noticed a moderate amount of carbon....kind of smelled like gas and black residue (I guess carbon). I will watch the videos again and take it from there. You are doing a great job on here. I will be sure to let you know how it all works out. This will be a small winter project lol. Thanks again!

[@maromaniac9256]

hey ozz i gotta tackle this on my 95 z28 whats the total hours it took just on removal and install?

[@ozzstars_cars]

removal and install about an 1.5 hours doing it professionally with all the correct tools. Cleaning the intake and throttle body adds more time. A do it yourselfer probably an entire day. Your car the access is harder, that will add time. Good luck

Awesome vid, part 1 and 2! (liked and subscribed ;) ) I'm troubleshooting a problem with coolant not returning to the radiator/surge tank from the overflow tank on a 1990 Vett with L98 motor. The line to the overflow was clogged so I though I had her fixed when I blew the crud out of the line, but the problem persists. Guess I'm to the point of troubleshooting bigger problems now, like the intake manifold, or head gasket leaks. Any advice?

[@ozzstars_cars]

I'm sure the entire cooling system is clogged. Its going to need a hug flush, including the radiator. To do the job right, both knock sensors should be removed. I would take off all hoses, tanks and flush all the crud out of the radiator. Then make sure the water pump is circulating the coolant. Thanks for liking and subscribing, good luck with the repair

[@jeffreyfreeman3211]

Did not see the intake being put back on is the on is the RTV silicone dry is silicone dry or wet when that happens Good video but skipped steps

[@ozzstars_cars]

I used gasket maker. Applied to the china wall like shown in the video and then the intake is set in place and torqued, it won't work if dry.

3:51 why do you have 2 oil sensors ?

[@ozzstars_cars]

One is for the dash idiot light warning, the other is for the analog gauge and also if it senses less than 4psi oil pressure it will cut off the fuel pump circuit. This is to prevent engine damage.
