is this fixable?I both this engine(jdm B18c)four-five months ago and when i went change timing belt i found this ,

 

I dunno if thats fixable but ouch doesnt look good...Maybe some jb weld??

 

I must be having a slow mental day here... that is the primary engine mount on the driver's side correct?
do the bolt holes look stripped to anyone but me?

that crack is not good but it's fixable. I'd have it welded personally.

 

all are stripped+that crack

 

two paths to repair.

weld up the crack, then carefully tap the holes to a slightly larger bolt and install.

weld up the crack, weld/fill the holes as well. Redrill and retap holes.

the second is the best idea but far from easy.

 

do i have to strip internals before i send it to weld it

i agree with number 2. also id say no, on the internals. Ive never seen something like that before, Id make sure the crack didn't go spread. I use to have a 02' gixxer 750 with a broken off engine mount. welded it up, ground it down to look somewhat like it use to be (it was shiny) drilled & taped it. It was good as new. never had any problems again. you should be fine

 

thx guys

 

I would say get just the crack welded up and then helicoil the stripped holes.

Much easier on the welder, do you have any idea how hard it is to tig weld inside a hole?

good luck with it

 

bring it to a machine shop

 

u can weld that but is going to be weak and it might end up cracking again, that happened to my friends gsr and it was welded by a pro but it cracked again...if it was me i would get another block and save myself a headache..sorry

#2 is the best also.

#1 you will need to get a carbide bit and drill out a larger diameter on the mount as it's pressed forged steel and impossible to drill with any standard regular bit.

 

JB weld the crank then JB weld the bolt, it will hold just fine.

 

first ask your self is the block worth it but yes its fixable at a cost

What are you smoking? It's not even a big deal. Have a welder fill in the crack for $50, then drill/tap the holes one step larger.

shut up
JB weld will NOT hold that from cracking again due to the vibrations the engine endures

 

+1 on the heli coil idea..........if there good enough for edelbrock there good enough for that

 

is funny how people waste their time talking ****, the block is not solid metal and the weld will be weak, like i stated before it happened to my boy and he weld the damn thing and it cracked again...

Considering that the motor/trans is held in with 5 mounts, and the mounts themselves dampen most of the vibration, recommending that he have it welded is not unreasonable advice.

He has a crack in 1 of about 15 bolt locations. Not exactly the crisis situation that would warrant spending hundreds of dollars to rip down the block and spend a week transfering everything over to a new block. He'd need a fresh hone, new rings, new bearings... what a nightmare. Just weld the ******* thing and be done.

+ x2

edit: don't forget to helicoil that biznach. Ask any seasoned domestic guy, they will take a helicoiled hole over aluminum anyday. Good luck with it.
