I recently worked on a 1996 Acura TL 2.5L, where I removed and reinstalled the rocker arm assembly. The service manual said to place ‘liquid gasket’ on a few particular locations where the rocker arm camshaft holder mated with the cylinder head. No part number for the liquid gasket material was provided. I assumed I should use some kind of Import Grey RTV, while one of my buddies suggested Indian Head Gasket material.

I was unsure which to use, so I started researching and came across Service Bulletin 99-030 dated 10 FEB 2007, which details the recommended materials for use on Honda/Acura vehicles. This is not to say other substitutes do not exist – it is just that these items are known to work by Honda. With that all being said, I still don’t know which gasket material I should have used and am going to try to communicate my understanding of the current assortment of Hondabond sealants.

UPDATE: Received newer Service Bulletin 99-030 dated 2 AUG 2012 and have updated information below.

Hondabond 4 Semi-Drying Sealant P/N 08717-1194 - Liquid gasket sealant used to seal critical areas as specified in service manuals. Do not use it for gasketless applications. (I believe this is the replacement for Hondabond 4 Silicone Gasket P/N 08718-0004 and is likely what I should have used on the aforementioned Acura TL.)

Hondabond HT Silicone Gasket P/N 08718-0004 - Adhesive sealer for metal-to-metal, metal-to-plastic, or plastic-to-plastic bonding. Good for high temperature applications. (This replaced P/N 08718-0001).

Ultra Flange Sealant P/N 08718-0003 - Gray Material used to seal areas as described in service manuals. It can also be used for most gasketless applications except oil pans.

Ultra Flange II Sealant P/N 08718-0009 - This thick gray material is the recommended product for sealing gasketless oil pans. It’s also the preferred sealant for most gasketless applications.

I went through several Acura and Honda service manuals and tried to determine if I could get away with just one sealant/gasket material, or, if I needed several, which ones I would need to have. As an example, if every situation sealant X was recommended, sealant Y was also recommended, then I knew I just purchase sealant X, especially if there were situations where X was called for exclusively, but not Y.

In the 2001-2005 Honda Civic Manual the part numbers 08C70-K0234M, 08C70-K0334M or, 08C70-X0331S are specified for use when installing the valve cover gasket.

08C70-K0234M has been superseded by 08718-0004. I couldn’t find any information on the other two P/Ns. In one of the RDX Acura manuals, I saw 08718-0001, 08718-0002, 08718-0003, or 08718-0009 listed together frequently, where any of them could be used, although there were a few situations where one or the other was specified exclusively.

08718-0001 has been superseded by 08718-0004. P/N 08718-0002 (which isn’t listed on the 99-030 Service Bulletin) has been superseded by 08718-0012 Hondabond HT 1216F.

I located a Permatex OEM interchange chart at ( www.itwpf.com.au/permatex/pdfs/approvals/7.pdf‎ ) and also turned to the Permatex website for the technical data sheet (TDS) for Ultra Grey Gasket Maker.

The Ultra Grey Gasket Maker TDS and the OEM interchange chart suggest that Ultra Grey will work as a substitute for 08718-0001, 08718-0003, 08718-0004, and 08718-0009. That means that Permatex’s Ultra Grey should work in lieu of the old and new Hondabond HT silicone gasket, Ultra Flange, and Ultra Flange II.

That leaves two items that I do not see a Permatex substitute for – P/N 08717-1194 – Hondabond 4 Semi-Drying Sealant and P/N 08718-0012 Hondabond HT 1216F. Does anyone have any idea where these materials are used? I honestly cannot find any information on HT1216F.

I think someone who works on Honda/Acura vehicles regularly should have on-hand: Permatex Ultra Grey to satisfy the 08718-0001 and 0004 requirement. The Permatex the Right Stuff Grey brochure says it will work in lieu of 08718-0001 (and one could assume 0004 by association) and 0003 but none are listed on the Permatex technical data sheet. Otherwise, you could get away with Ultra Grey or Right Stuff Grey to cover almost everything. In addition, Ultra Flange 2 is required to satisfy the situations where 08718-0009 is required unless it can also be satisfied by Ultra Grey or the Right Stuff Grey - it's just not listed in their TDS.

The only requirements potentially not met at all are when Hondabond HT1216F (P/N 08718-0002 or 08718-0012) is called for and when Hondabond 4 1194 (P/N 08717-1194 or 08717-0004) is required.

Lastly, if anyone knows the application of Hondabond 4 1194 and/or can speak to the uses of HT1216F, please share.

I went through every Service manual I have and looked at when a gasket sealant was required. I wanted to see if there were particular items that were always alternates of one another and see which were listed by themselves.

The list below details each example where a gasket P/N was called for, and which alternates would suffice in that exact application. If only one item is listed, that means that item was exclusively identified. Lastly, the text in parentheses details the newer version of the item required in the manual.

08718-0001 (Hondabond HT 08718-0004)

08718-0002 (Hondabond HT1216F 08718-0012)

08718-0009 Honda Ultra Flange 2

08718-0001 (Hondabond HT 08718-0004) or 08718-0002 (Hondabond HT1216F 08718-0012)

08718-0001 (Hondabond HT 08718-0004) or 08718-0003 (Honda Ultra Flange)

08718-0001 (Hondabond HT 08718-0004) or 08718-0002 (Hondabond HT1216F 08718-0012), 08718-0009 (Honda Ultra Flange 2)

08718-0001 (Hondabond HT 08718-0004), 08718-0001 (Hondabond HT 0878-0004), 08718-0003 (Honda Ultra Flange), 08718-0009 (Honda Ultra Flange 2)

08717-0004 Hondabond 4 Silicone Gasket (Hondabond 4 Semi Drying Sealant 08717-1194), 08718-0003 (Honda Ultra Flange), 08718-0009 (Honda Ultra Flange 2)

08717-0004 Hondabond 4 Silicone Gasket (Hondabond 4 Semi Drying Sealant 08717-1194), 08718-0001 (Hondabond HT 08718-0004), 08718-0002 (Hondabond HT1216F 08718-0012), 08718-0003 (Honda Ultra Flange), or 08718-0009 (Honda Ultra Flange 2)

08717-0004 Hondabond 4 Silicone Gasket (Hondabond 4 Semi Drying Sealant 08717-1194), 08718-0001 (Hondabond HT 08718-0004), 08718-0012 (Hondabond HT1216F), 08718-0003 (Honda Ultra Flange), 08718-0009 (Honda Ultra Flange 2)

Almost every application called for either08718-0001 (Hondabond HT 08718-0004) or 08718-0009 Honda Ultra Flange 2. There was one situation I could find where 08718-0002 (Hondabond HT1216F 08718-0012) was called for exclusively. Also, I was unable to find an application where the Hondabond 4 was called for exclusively.

In closing, get a tube of either Hondabond HT 08718-0004 or Permatex Ultra Grey, which should cover almost everything, and a can of Honda Ultra Flange 2 08718-0009 for gasketless oil pans and a few other niche applications.

Nissan 999mp-1217 is the ultimate gasket maker. Been using it on everything for over 10 years. Hondas,Toyotas,Nissans,Fords,GMs,etc. And guess what,it is Permatex Ultra grey,rebadged.

blackeg

for anything related to inside the motor i always use the grey (yeah permatex)

for slightly leaking exhaust gaskets i use the red **** that smells like vinegar and i hate with a passion

GhostAccord

x2 Permatex Ultra Grey. I use it in all the locations noted in the shop manual to use liquid gasket sealant.

Digging up this old thread with very useful information

I was looking for Hondabond HT (08718-0004) to seal the oil pan of my Honda Accord, and found out that there is a new stuff that replaces the Hondabond HT, called "Honda liquid gasket 1216E" (08CRA-HLG-120G), as can be seen in:

• Genuine Honda Parts | Honda Cars | Honda Motorcycles | Honda Power Products | Lings Honda Parts Search
• https://www.parts-honda.uk/honda-cars/price#
• 08CRA-HLG-120 Honda Liquid Gasket 1216E - 120 genuine new - KFM-Motorräder

Does anyone have any experience with this new stuff? Any recommendation between these two? In some places, like in local Honda shops in Portugal, I can't find the Hondabond HT, the part number was replaced by the new one....

I was trying to stick to Honda stuff. Also, it's not easy to get Permatex stuff in Portugal
I also have question about Ultra Grey: How do you use it? In the Permatex site (https://www.permatex.com/products/ga...asket-maker-2/) they say to first finger tight the bolts, wait for an hour, and only then tighten the bolts:

I mainly use Hondabond 4 Semi-Drying Sealant P/N 08717-1194 with great success. I've used it on valve cover gaskets, K-series oil pan, timing chain cover, main seal, block girdles, transmission housing, etc. No leaks at all. Just clean the surfaces and properly torque the bolts down. I've tried the Hondabond HT stuff and while it does work well, it is a bit more difficult to apply cleanly since it is thicker.

Thanks. I plan on using Ultra Grey for everything, but thought about the Right Stuff for where the coolant outlet mounts to the head on a B18C1.

It seems, Permatex Ultra Grey is indeed a poor substitute, because of its higher "tack free time". This is the time when the sealant no longer feels sticky. This is different from "cure time". Hondabond HT and Three Bond 1207B both have a "tack free time" of 5 minutes whereas Permatex is 1 hour. Also the Hondabond and Three Bond can resistant temps up to 600F whereas as the Permatex Ultra Grey is 500F. For shade tree mechanics who have to fix their car on the side of the road or parking lot, this is the deal breaker.

An oil pan gasket is a 5 hour job for an experienced individual who uses a floor jack and jack stands, therefore saving 10 bucks on RTV is illogical imo.

Me personally I'm leaning towards Hondabond HT over Three Bond 1207B, since the latter is black instead of grey, and from MY EXPERIENCE Honda Bond HT doesn't require special chemicals like acetone to get it off. I've never tried Three Bond; it is 30% cheaper per oz. than Hondabond, but I don't know how easy it is to clean off. Permatex Black is supposedly a PITA to clean off, requiring harsh chemicals which could potentially damage rubbers like valve cover gaskets.
