I am a Jeep rookie and just bought a 95 Yj, 4.0L, 5 speed. The passenger side engine mount only has 1 bolt in place. One of the other mounting holes (on the actual block) is chipped enough that a bolt will not hold and the other has a tap broken off inside of it!! It is still driveable but I keep the revs low and the acceleration easy so as not to break the remaining bolts and 4 wheeling is obviously out of the question. I have seen lots of posts with broken bolts but this is the actual hole in the block that the bolts screw into that are a problem. Any ideas on how I can fix this?
First off on the passenger side of the engine has the oil filter on it. I broke the passenger side engine mount on mine, while on a trail I should not have been on , and it crushed the oil filter. I had no choice, the fine would have been more than the repair, but to continue on. Luckly I was only about a 1000 yards from the bar, so I just pulled into the barn there and left it for the morning. I would not recomend driving it at all if possible. Unfortuantly the correct repair if the engine block is broken is to replace it. Can you post some picture's? Maybe if we can see the dammage we can come up with another idea.
the bolts for that mount broke on my wife's 93 a few times. drill the tap out and get some really strong bolts for the two holes you will be able to use.
it sucks when the mount bolts break and the engine drops on to the oil filter. happened to us each time those bolts broke too
A lot of teenagers are people who express a burning desire to be different be dressing exactly alike.
Panties aren't my favorite, but they're right next to it...
No one is normal, there are just a lot of weird people with things in common.
Here is a picture of my mounts, they are pretty messed up. One of the holes (the one with the tap) is a write off so I am going to first try to use the existing one and weld the chipped one giving me 2 solid bolt ons. My buddy is a reaaly good welder and I thought I would give it a shot before spending money on the brown dog bracket. Has anyone had a similar situation and used these brackets successfully?
I had a similar problem, I had to drill and tap out the holes to 7/16's.
I was in a similar spot to you (minus the one broken mount), the PO tried to drill one out and broke the drill bit off in the hole(then left it and ran with 2 bolts), so I had to drill through an old bit just like your tap. It took a long time, a few drill bits and REALLY sucked, but I eventually got it.
If you choose to say "plz" because it is shorter than "please" I choose to say "no" because it is shorter than "yes".
Welded two peices of 2in flat bar top and bottom of the bracket and drilled holes so I could use other bolt holes on the block. It held together good till I feel asleep and put my jeep in a ditch at 55. I rebroke the mount but only the top leg. I rewelded and drilled to more holes to bolt the top leg.

Thanks guys, this is all super helpful info. I have now welded the chipped one and have the one normal one in place and I tested it by torquing it pretty good in high and low gears. Seems to be holding out so far. What do you think my chances of survival are? If it breaks again I will get the brown dog bracket. I talked to Tim there the other day and he was extremely helpful.
OK. As I suspected, the weld did not hold which leaves me with one good bolt attached to the mounting bracket. Before I lose that one, I have gone ahead and ordered the Brown Dog Super Bracket. It is a bit more than I wanted to spend but it will do the job and save me from other more costly expenses in the future. I will update y'all once it is in and I have gone 4 wheelin!
