Extra holes in the front beam

[guaynabo89]

why not just drain the hydro mount and fill it with epoxy?

it still breaks

[Vanilla Sky]

ahh, ok.

i wish we had the mount inserts and options the civic/integra guys have...

[carotman]

Yup, the hydro mount still breaks even filled with hard stuff (learned the hard way)

I didn't try the rear mount as a stock unit. I didn't want to take any chances after breaking 2 front mounts. I can't say it will hold strong but it's worth a try.

You can't use the USDM metal bracket with that rear mount. However, you might be able to modify it to fit. Let's say you enlarge the bolt hole in the bracket so the nut can come right through it. Then, weld a pipe on it (like 1 inch) and plug the bottom end of that pipe shut. After, drill that same end so the mount's bolt can come through. This would make a perfect spacer.

I also thought about the ingalls damper. I was looking at the front X-beam and we all have this useless rubber thingie bolted there on the right side (held by 2 10mm bolts). I was thinking about fixing the damper there and bolting it somehow to the tranny bellhousing. This would give an extra strenght to the front mount and prevent excess movement.

we'll see which way is better since I plan on going turbo so it might interfere with the plumbing.

Well guys.... BAD NEWS.

I broke the front mount on Saturday while doing the Road trip with the Toronto Accord Club. The mount broke in half while pulling hard on the Expressway on-ramp. I'm lucky it didn't break anything else!!!!!! I was in Niagara which is an 8 to 9 hour drive from where I live!!! I was able to make the trip back home (lucky me) but I just didn't enjoy the ride as much as I could have at this point... I hate how they designed that thing.

I guess that my round bushing mount idea is the next thing to try.

[Cheeseburger]

dam taht sucks, PICS lets see how it borke!

[Vanilla Sky]

wow. your car must be making good power to rip up mounts. and yes, i have seen your dynos.

yeah, you're going to have to go with something stronger. think they'd hold up better in urethane?

[lostforawhile]

the solid dog bone really helps,I broke three mounts in the front before I put it in. if your rear mount is worn it will also cause your front mount to work harder and break eaisier,also if your side mount is broke it can cause the front to break. If you break a lot of mounts carry a spare and a small bottle jack,it's pretty easy to change,also some wood blocks.

[carotman]

The mount basicaly broke in half. It was filled with Eurethane but still broke. That solid dogbone really helps I guess. I will thing of something to replace it or change the front mount design. The "bell" shape they have is just a bad thing for a mount that works in traction instead of compression.

I'll take pictures of that broken mount. I still have to remove it. The fun thing is that I was still able to to 75/80 mph on the highway without problem.

The rear and side mounts are filled with eurethane too so it might help a bit.

[Vanilla Sky]

what i meant was the entire thing cast in urethane. i had an idea a while back to make molds for the mounts and cast them in urethane. you can get bulk urethane from mcmaster-carr.

[carotman]

Well, I think I got rid of the problem for now. I installed the solid front mount I got from JohnnyO. The rest of the mounts are still stock (filled with Eurethane). It's surprisingly not too bad. I do get some vibration at like 1100 rpm and a bit at idle but it's comparable to when I had that rear mount in thr front (in good shape).

I guess I got rid of the problem for good. I'll definetly come up with something else in the future but for now, i'm not afraid to break this one anymore.

did the solid mounts really work?? do you think with the solid mounts something might break since the engine isnt flexing like its supposed to im trying to get some solid ones too cause i break mine too

[Xulfiqar]

A16 use the same mounts front and rear thats why its there

[acranox]

That "damper" is a harmonic damper. Basically vibrations transfer from the engine to the frame, the damper absorbs the vibrations to keep from the transfering to the body. It reduces noise and vibration in the car. You probably won't notice the difference if you remove it, but you might notice something. Usually at a specific RPM there can be resonance created, and the engineers add these dampers to reduce the effects. I'm sure the difference was more apparent when the car was new.

[thegreatdane]

Hey sorry to hear the mount didnt hold up! I was just about to say you should just go with a solid front mount but I see you already took care of that. In the future I'd also like to use a round rubber front mount like just about every other honda engine does.

[guaynabo89]

Bringin this one back.

Well I broke my front mount again and got another new one and decided to install one of those engine tourque dampers while I was at it.

Well the point being is that I didnt notice right away is that the new front mount I got made the engine sit a little higher on the front makign it lean towards the drivers side. I figured there was probably a difference between the 86-87 mount and the 88-89 mount since the 88-89 use a cast bracket compared to the 86-87 stamped steel one. I was going to take my recently purchased front mount back to the store to compare to see if the height thing was corrct between the different years. Well it came to me and remmembered this thread and since I had and extra rear mount laying around for some reason I decided to try it to see if it fit.

To my surprise it fits perfectly there with the 86-87 stamped steel stock bracket. the only benefit I can see from this is that this mount is stronger filled with poly than the hydro one filled with poly.

Anyway thought Id share.

[carotman]

In fact, even with the 86-87 bracket, it will sit a bit low. The ideal bracket is the A16A bracket.

[guaynabo89]

Well I placed a level on top of the valve cover and the engine does sit level. now i dont know if its leaning forward more. it looks the same but without the correct hydro front mount i dont have any reference point. when i return my front mount i ll hopefully get the correct one and be able to compare

[lostforawhile]

let me know if the level is the same,I want to change my front mount,but i have very little clearance between the air cleaner and hood scoop. I can rotate the air cleaner,but it will involve changing some of the bracketry

Well I took my the rear mount and the front rear mount out to try and fill with some 3m window weld.

My car is a manual and the rear mount I used in the front is from an automaic. Well I put the two side by side and the auto rear mount is a little taller than the manual rear mount. Its only taller by like 1/8 of an inch or so but its definately taller. The manual rear mount also has a smaller hole in the middle.

Anyone know how long the window weld stuff take to dry?

I guess if you use an Automatic rear mount in the front it will make the engine sit level.

i read somewhere(cant remember where) that its best to leave it drying over night, id say maybe like for ~8 hours

[guaynabo89]

Well as of right now its been a full day and its still wet in the middle. I figure like 3/16ths on each side is dry while almost the whole middle( about 1 inch) is still wet.

Im going to leave it out in the sun all day today to see if that helps.
