Well I started putting my oil pump on and one of the bolts broke in the front side housing. Tried to get it out with a bolt extractor but the damn thing broke off inside. I have no machine shOps willing to try and remove the bolt and I'm not really wanting to break down the engine and send the front side housing. My question is would it be safe to use with just the other 3 bolts holding the oil pump in place without any loss of oil pressure ???

 

id get it out, that would be like installing a exhaust manifold with only three bolts..

 

Man, you'd really be pushing your luck. Yes, it's gonna suck, but get it fixed RIGHT. It's going to be a lot less work to fix it now than to pull the engine back out and redo everything.

Options -

- Load up the engine in a car (I assume this is an assembled long block) and find somewhere in town that can do it. Call around, I'd call some mechanics and ask if they knew somewhere to do it. Get that broken bolt out, make sure the threads are good, and you're done.

- Break the motor apart and replace the front housing with another one. Not TOO bad to do at this phase, you'll have to clean the RTV on the rotor legs off and keep the rotors put together with rubber bands, but it's doable.

Just, please, PLEASE don't just reinstall it without. That's just asking for trouble. Take a deep breath and do it right.

Those bolts are soft. You should be able to drill it out and if necessary retap the threads.
Ask me how I know.

I am local and can help you out. Ill send you a pm shortly.

 

And the peasants rejoiced

You really gotta watch the torque on the oil pump and oil pan bolts, the proper torque is only measured in in. lb. on those.

 

I'm curious as to what you're doing.... attempting to build an engine? You'd have to *really* try to break one of those bolts.

 

impact on one of those bolts isnt the best route to go heh

 

Yea I went out and bought a drill and tap set. Yea it's a new build with all new side housings and low low miles on the rotors and rotor housings. Well I was looking at the dealership book and notice that it was inch lbs. I didn't apply that much to them but the bolts I used were over tightened and I finished them off. The thing that sucks is that I have been planing on this engine build the last 3 years Yea I'll end up just making the size bigger cus the threads are not good.

 

I feel your pain but don't feel so bad. I doubt there's a soul out there that hasn't done something like that at least once. Takes some guts to try and rebuild an engine by yourself, especially if you don't have someone to show you exactly what to do. Everyone that's ever built an engine had to learn somehow.

You just need to be willing to accept you might fubar it, and do your best to prevent that from happening.

On the other hand, having an engine roar to life that YOU rebuilt will put a big stupid grin on your face.

**watch the pickup tube bolts too btw

 

Before you start drilling, tapping, etc make sure you use paper towels and tape to mask off the oil passages so that you don't get metal shavings in places they shouldn't be
