Any broken bolts on the front of the engine should be easy for a professional to remove.

It's the head and manifold bolts that are most difficult to access and remove. Accessory bolts - easy peasy!

I certainly wouldn't replace an engine because of a couple of broken bolts.Like previously mentioned before,if I couldn't do it myself I would take it to a good repair shop and them remove the broken bolts.and if they can't do it either,then I would have the bracket or whatever it is,welded to the block.

If the motor is still in the MH, taking it to a machine shop might be a problem. I suggest calling around to locate a machinist that is willing to bring his tools to your MH and extract the bolts or drill them out and re-tap the holes. I certainly would not spend the money to replace the block before having a machinist try to remove the bolts.

I would buy a new rv. My answer to the original question.

broken bolts are generally a piece of cake. The easiest way is to place a nut over the top of the broken off bolt. You can do that even if its even with the surrounding surface. Then weld the nut to the broken off stud/bolt. If its small enough, you can do it with a wire feed, but in general a tig welder makes the job easy. I generally just hold the nut in place with the tip of a screwdriver and then touch the tig torch to the broken stud enough to stick the nut to it. Then fill up the nut with steel rod and you can just turn it out when it cools. Make sure you wait until it cools some. They normally come out quite easy because of all the heat you used.

courtjester:

Great suggestion. I'll include that idea the next time I break off a bolt. Thanks!

I'd say 95% of bolts that we get in at the shop break due to the threads being seized in the hole. If you are lucky and it didn't break off flush with the surface you may be able to use a stud puller but usually the bolt just snaps again at the surface. If it is seized usually nothing is going to take them out but time and a drill. Can't tell you how many people have brought this type of work to the shop with some sort of easy out busted off in the bolt. If the bolt is seized in the hole an easy out is not going to work. Not an easy job at all especially when the engine is installed. May be impossible to drill out while still in the vehicle even with a 90 degree drill, access sometimes is just impossible. Also unless your very good at it you will need to helicoil the hole after you drill it.

I have to bolts broken off in the block and extractors won't work and im not ballsy enough to retap it.any tips would help to fixing my problem id rather not have to buy a new engine or rv.

My thoughts are to just repair it and it's not like the engine is completely shot. Even with a new engine in a nice coach, you'd be lucky to realize $3K for it in a sale and would be giving it away in a trade.
