Block Off Plates. RTV or OEM Gasket?

I decided to replace my LIM rather than fix the stripped threads in my manifold. The issue is that I have to swap my block off plates over to the new manifold.

The question here is, Should I be fine if I just use RTV to seal the block off plates to the LIM? It seems that the previous owner or shop that installed them used a combo of OEM gasket and RTV.

Also for my OMP block off do I just use RTV and not worry about the rubber O-ring that came off the OMP?

Thanks for the help,
Ryan

Depends on the quality of the BOPs, ours can be installed with just the oem gaskets or with just a thin layer of RTV (prefer Ultra Grey or Black). Just use RTV on the OMP plate since the o-ring mounts in the pump not the front cover.

My block off plates are unique. They are either ancient or a custom fab. I will get pictures up when I get home later.

i used rtv with mine but i also got mine from banzia racing about three years ago.
where there was anything with oil involved i used oem gasket one of the nicest things i have done esp. since i went sinigle, it helps clear up a few things under the uim.

Here is a picture of my block off plates, I am not sure where they are from. Plan to upgrade them to Banzai plates when the motor goes for a rebuild in a few months. These are only for the LIM and I will be using RTV on them for the time being as I just want to get the car running and install my simple mods before the rebuild.

Thanks,
Ryan

You are going to need to use a bunch of RTV since they are not very flat. You want to avoid vacuum leaks from all the grooves and pits. Definitely homemade and pretty rough.

You might just want to spend the $50 and get our kit so you don't have to do this twice http://banzai-racing.com/store/FD_block_off_plates.html

If you have a sander of some sort just take some time to sand them flatter.

I have access to a mill so I can face them off if that would make them seal better.

Those look horrible. I think I was the first guy selling block off plates. Yours look cast, not flat and with voids.

They are definately not cast. They were machined in some way. Probably cut out with a band saw rather than a CNC or water jet.

I think I will just face them off with the mill and then I will have whatever shop thats doing the rebuild in the near future install Banzai plates on everything. Already have a Banzai OMP block off so I know the quality.

Faced them off this afternoon and now they are nice and flat. I will be installing them this weekend.

Does anyone know the torque specs for the plates that go on the LIM off hand? I assume like 20 in lb or something around there.

Didn't think it would be that easy did you?

Also, I like HondaBond. It's pricey but hands down the best sealant I have ever used.

I will be using "the right stuff" because I have some left over from my oil pan sealing adventure. I will keep that in mind for the future though.

Honestly dude it is just a block off plate and if it is thick enough then you can put right stuff on it torque it down and then come back and re- touch them after the right stuff has dried. You plates look a hell of a lot thicker than the other kits I have seen. Hell I picked up a kit from ebay for 20 bucks shipped and its thicker than most kits out there.

By the way nice touch on milling the surface those look pimp!

Those places should all use the small 10mm nuts so the torque specs will all be the same. For those which have studs, I would replace those with bolts (it will give a cleaner look on the install).

It's the little things now, that make the difference later. The little bit of money for quality plates, good gaskets, and sealant is worth the peace of mind.

Hondabond everything! You want to talk about doing it right the first time, use hondabond. Especially useful on other items prone to leak, like the oil pan.

I agree with you on that bud, but when you pay 20 bucks for a full set of block off plates.... you think it has to be crap.

Then your friend gets a set from a reputable company and my plates look thicker and made of great quality makes you think if the companies charging more money are making a killing on us.
