engine mount problem help plz..

[Pjamaz]

hey guys.. well im havn problems with my siR.. the 3 thread holes that bolt the passenger side engine mount onto my engine block have stripped and 1 of the holes have actually had a chunk taken out from it so there for there is no more thread.. is there anyway i cud get this fixd and how much am i looking at?.. i can take the engine out myself if that helps..

Not a good thing man but it is fixable,
I had a similar issue when i removed my b18c from a wrecked integra vti-r, one of the bolts got stretched so you couldnt tell anything was wrong then my rear engine mount broke and the side mount twisted and turned and stripped 1 thread and snapped the bolt in the other. what you need to do is either jack up that side of the motor and remove any plastic covers in the way so that it is completely exposed or just lift the motor up a little, shouldnt have to remove too much, Now if your capable do this urself or hire someone (shoulndt take more than a couple hours). You need to get the threads drilled out so that you just have these three holes in the side of the block and as you can see there is alot of material still there to tap into, Now you will need a tapping set that is the correct size for the whole that is drilled and tap away, you will be left with 3 fresh little bit larger thread holes to bolt into.

1.Make sure you have 3 bolts same length as stock that will fit the new thread patern before drilling or tapping
2.Make sure not to drill any deeper than the original holes are
3.You might need to slightly bore out the mount holes to accomodate for new bolts
4.As long as you drill correctly should be fine but make sure holes are aligned


Sorry wrote this in a rush so excuse if its a little hard to understand lol.

Thanks

To do it yourself,
You'll need - http://www.powercoil.com.au/
+ a few other tools.

Since you're in Sydney,
Call a thread repair guy.
Here's 2... You pay a fee for them to turn up & then how long it takes.
If you've got the engine out & the area clean & accesable... All good.
If you're not confident fixing it yourself, do not attempt the job.
You may actually make things worse & end up costing you more.

i've had a similar problem with my old B18c. You'll definately need to remove the engine from the engine bay.

If the thread is completely stripped, you'll need to drill and re-thread the hole. This means a bigger bolt will be used. This will also mean, enlarging the bracket hole which will require an engineering place which specialising in drill to do. It costed me 60 bucks to enlarge 2 holes. Apparently it requires a special drill bit. (there is a place in wetheril park which did my one)

thanks for the help guys. But yeh two holes have been stripped but the third hole has a large chunk of metal missing from the block.. so instead of having a round circle, its half a circle.. so i think it needs to be re-welded or something..

You need kneed-it ;)
It's a metal putty product that works. (Like defcon only better)
(Use the alloy one, not the steel one :thumbsup:)
Use it then drill & tap as parent metal.
Other 2 threads should be recoverable with re-coil insert, or twin-sert if they're really bad.
Don't use oversize bolts just yet, the re-coil is cheaper.
(it reclaims the original thread)
