97-01 PRELUDE oil cooler seal replacement.

[@IAutoEnthusiast]

Whats your lest favorite oil leak?

[@cbdreamer1709]

Crank and rear main seal. Lol

[@IAutoEnthusiast]

Agreed. To much work fot the rear main seal.

[@Alien_A-7]

My coolant reservoir is getting oil, is this the main cause?

[@IAutoEnthusiast]

@@Alien_A-7 majority of the time that oil and coolant mixing means it's a head gasket issue. An oil cooler that uses the coolant system and is defective could cause the transfer from one to the other, but further diagnosis would help find the reason.

[@Alien_A-7]

@@IAutoEnthusiastThank you for the quick reply. My first impression was the head gasket but when I checked the engine oil, it is very clean. No sign of coolant inside the engine. . I've read some blogs and they said it's the oil cooler seal then I found your very helpful video how to. I really appreciate you helping like us with very small knowledge in auto repair.

[@franklynwilliams1257]

2years later and man you video just helped/saved me money, got worried it was bad but I found the leak and then found your video

[@IAutoEnthusiast]

Glad it could be helpful. When the seal goes it's a messy pain.

[@Gwyntomology]

Spent a while looking around for leaks and fearing the worst, I found an active leak on that seal of my 99. I didn't even know that was a relatively common leak. Thanks for the vid.

[@IAutoEnthusiast]

Thanks for the comment. Glad the video could help.

[@Gwyntomology]

@@IAutoEnthusiast You and a handful of other YTers have taken me from someone who spent a lifetime saying they can't even change oil, to looking at videos on how to adjust clutches and replacing o rings.

[@IAutoEnthusiast]

@@Gwyntomology we all can learn new ways to do things. No one is an exception to the rules. I'm glad someone can use the info as I had hope someone could.

[@khamteh29]

Great educational video! Good alternative way, (instead of filling the oil filter with oil) is to disconnect the lead to the dizzy and prime the engine about 5 short times to get oil pressure.

[@IAutoEnthusiast]

Smart. Thanks for the tip.

[@raylyd]

Thanks I gotta do this on my 98 oddysey f23a7 engine

[@PieckuF]

I know this comment is a few months late but this video was a huge help and I just wanted to say thanks man. My Lude pisses oil all over the driveway and I am 99.99% sure this is the cause as I've already dealt with the VTEC solenoid gasket and valve cover gasket. I suppose there's only one way to find out. Thanks again!

[@IAutoEnthusiast]

Thats a great response. I am glad I could help in some way. Thanks for letting me know. It is much appreciated.

[@juanc5149]

You should try this on the SH! Even less room, AND the oil cooler is facing downwards, so the O-ring just falls out. I think I’m going to use assembly lube or even valvoline to get it to stick.

[@IAutoEnthusiast]

Thanks for the reply. Using a thicker lubricant to aid is smart and will make the job easier.

[@Alien_A-7]

Thank you so much. I have the same issue with my 04 civic. Now, I know what to do.

[@IAutoEnthusiast]

Glad I could help in some shape or form.

[@VR6NAVYVW]

Try using a small amount of Vaseline in the groove where the ring sits, then push ring on and it will hold.

[@IAutoEnthusiast]

Great idea. Thanks for adding to the video.

[@rico4260]

Yes! I just did this 2 days ago on a sh so I have to reach from above.. vaseline, lighting and patients.

[@timothydavis3348]

Vaseline won’t hurt it?

[@ethanoshea4102]

Found this video because I went to go buy a 97 prelude and the guy said that the cars leaking from the oil filter which is common apparently. Think he might have meant the oil cooler well atleast now I know, thanks

[@IAutoEnthusiast]

Good to hear, knowledge is power. Thanks for the comment.

[@nateduerst7008]

God bless you bro thank you.

[@IAutoEnthusiast]

Welcome. Glad it could be made available and useful.

[@jessehamm7156]

Gotta do this on my 98 now too. Nice vid!

[@IAutoEnthusiast]

Thanks.

[@jessegodinez5968]

Great video 👍👍

[@IAutoEnthusiast]

Thanks. 🙏

[@debeerpaul]

Wow Thank you for this video. I have to do this on my 98.

[@IAutoEnthusiast]

Welcome. Glad it can be of use to other Lude owners!

[@moomoofun2150]

Trying to do mine but I took off the old o-ring and it's a squared off orange one, not the slim cylindrical black one Honda gave me, any idea why?

[@IAutoEnthusiast]

Are you working on a Base model Prelude, or the SH model Prelude

[@Gavstermavster]

Where did you get the o ring can’t find it on autozone what the measurements for the o ring

[@IAutoEnthusiast]

I purchased the o-ring from my local Honda dealer.

[@Jay-zy6pz]

Thanks for this video ,but after I changed the o ring I noticed there was a leak on top of the oil cooler. There is a small hose attached to it .Any idea where that oil is leaking from?

[@reecekeeble3443]

I have noticed the same thing. Did you figure out what it was ?

[@Jay-zy6pz]

@@reecekeeble3443 yeah I did some research and it is the rear main seal look it up.If you have excessive leaking I would go and get it replaced ,depending on the leakage

[@IAutoEnthusiast]

Hope this helps. Have and questions or comments? Let me know......👍

[@chocosidronio]

Are these the same on the 96 honda odyssey it looks like they are.... but not sure.Thanks.

[@IAutoEnthusiast]

@@chocosidronio not the same design. But the concept is the same.

[@racsowang]

Very helpful vide. I plan to do this next weekend. Got a quick question, what's the symptom before doing this? Will the dripping oil fall onto the exhaust and create smoke?

[@IAutoEnthusiast]

@@racsowang if the oil seal begins to leak, slowly. Yes, it will drip near or on the exhaust. If your seal fails, your oil pressure will be lost, the oil will leak very quickly onto whatever surface the vehicle is on, and your oil light on your dash will come on. There will be little to no oil pressure to operate the motor.

[@racsowang]

@@IAutoEnthusiast Thanks for the reply! My leak is fairly slow ( 1 drip per week on the garage floor) . I just bought the o-ring & all tools and will try fix it next week. I saw you have the exhaust removed, is it necessary for this job? Also I am wondering if I need to drain the oil to do this. Thanks!

[@ferrari_23king55]

Yooo dude that electrical wire how do you re-connect it ? Plyers or something

[@IAutoEnthusiast]

Are you talkin the oil pressure sending unit wire. If so it has a Phillips screwdriver attached to hold the electrical connection.

[@jfGarage4k]

Bro how you doin? Your upload and most contents?

[@IAutoEnthusiast]

Will be back. This year for sure!

[@EvOxNike]

Sorry, didn't watch the video entirely but can the oring cause no oil pressure at all? Because i am having a problem right now in my 99 prelude where i have no oil pressure. We replaced the pressure switch and just changed the oil and filter, but still none. (This problem started happening when I missed a gear and just banged off the rev limiter in neutral. Any ideas what it could be?

[@IAutoEnthusiast]

If you can not find a leak from a seal or gasket. I'd look at the oil pump, may have to be replaced and removing the pan to look at the oil pickup tub, could be clogged. Vtec solenoid gasket replacement as well for the valve head. How many miles?

[@EvOxNike]

I_auto_enthusiast never thought about it being a gasket. It has about 162000 miles

[@IAutoEnthusiast]

@@EvOxNike let us know what you find. I would like to hear about it.

[@EvOxNike]

I_auto_enthusiast alright I’ll let you know if we decide to fix it instead of just getting a new engine

[@RightUpYours]

Would this cause a massive oil leak under the passenger side of the car? I can't find the source, and I see no evidence from above or under the car

[@IAutoEnthusiast]

I've seen front crank seals leak so bad that they leak towards the middle of the oil pan. Rear main seal could be a factor. The oil cooler seal is my go to if it leaks large amounts. Even if it is not the oil cooler seal, replacing it is a good thing.

[@IAutoEnthusiast]

You may also inspect the transaxle for sides of fluid leaking.

[@RightUpYours]

@@IAutoEnthusiast I'll check what I can tomorrow. Yeah it's a large amount. Right after an oil change too.

[@shankerbhardwaj]

Do you have to drain all of the car’s oil before removing oil cooler? Will the entire oil system flush out or just a little that is sitting in there?

[@shankerbhardwaj]

So drain engine oil before replacing seal?

[@IAutoEnthusiast]

No, the oil remaining in the pan will not come out of the oil cooler. There will be some oil remaining in the system that will find it's way out but not a ton.

[@jamesjope2357]

Do you need to drain all of your oil to do this replacement? Or can you get away with just draining the oil filter?

[@IAutoEnthusiast]

You could get by without draining the oil. Might make a mess, but when these seals give, they make a big mess. Just make sure you go slow and ensure the oil is cold.

[@jamesjope2357]

Thanks a lot. Drained the whole system. The video was super helpful!

[@IAutoEnthusiast]

Glad it could help.

[@MangBertz0417]

will a 9136-pt6-003 oem gasket work on my 01 prelude base?

[@IAutoEnthusiast]

It should work on all 97-01 base Preludes, with a H22a4.

[@cbdreamer1709]

Dang bro. Is that a real thing about the oil filter. Crazy. Does it really make a difference? What exactly is the benefit?

[@cbdreamer1709]

Thanks for the video. I definitely don’t do that.

[@IAutoEnthusiast]

It is a practice. An opinion that the oil pressure being delivered to the important components can drop off as oil fills the filter. If the filter is already somewhat full than the oil being delivered has less drop off time, maintaining the pressure. It may not be important to some, but to performance builds, any practice that can reduce premature wear is something to consider.

[@duckmintNZ]

I got charged $600 by some horrid licensed "mechanics" to fix this when the O ring leaked. They screwed it up and charged me more to fix their screw up. Only finding this video now that I'm selling it 😅

[@IAutoEnthusiast]

@@duckmintNZ that's unfortunate, sorry to hear of your experience.

[@notacoyote2790]

Is this a prelude sh?

[@IAutoEnthusiast]

No, base model

[@notacoyote2790]

Is the sh the same? I have a 99 sh

[@notacoyote2790]

I really really wish I had a base model

[@IAutoEnthusiast]

I understand.. Base has a simpler design.

[@Achisachis73]

Too easy without the ATTS unit blocking the way. Mine still leaks.

[@IAutoEnthusiast]

Achisachis73 I'm glad I don' t have the SH model.

[@Achisachis73]

@@IAutoEnthusiast I am glad I have it, it handles very well on the curves. I am not about high speed on a straight line, I love going doing the canyon on hwy 70 feeling the grip of the SH suspension. Like anything else, the more bells and whistles the more stuff to break and the more complicated it gets. cheers
