Oil pan bolts that secure the pan to the block, what size are they?

[Machew]

Hello everyone, 

I have an 2011 Journey with a v6 I've changed the oil pan because they *whom ever did maintenance before* torqued the pan plug too tight, so it ended up being rounded off.  I removed the pan.  Everything went normally while I was tightening the bolts that secure the pan to the engine, then one of the bolts snapped, mind you this happened a few months ago, and its about time to change the oil again.

I've been meaning to switch/repair this bolt, but am having a hard time finding a part number for it.   I have a few questions:

1.  What will be the easiest way to extract the snapped bolt?  

     1.a what size extractor will be ideal?

2. What size or part number are the bolt/s I need for the repair?

3.  Is it advisable to just go ahead and get a pan gasket to help alleviate the slight leak I am having now ?

 

Thanks for your time!!

Ok, here we go...

 

- Don't know the size, but here is a link to the part #

- Removing the broken one can be done by attaching an extension piece with Krazy Glue or JB Weld and patiently unscrewing with a wrench. Otherwise drill it out carefully without ruining the thread. 

 

-YES, change the gasket

 

Did you get the drain plug out? Or are you doing an oil change by removing the pan? You may want to consider just getting a new pan. If the drain plug was over tightened, it may develop a leak if the threads were warped.

Confusing. Probably M4 just bring one to a good auto parts store and they can match it.

 

If one bolt is missing/snapped it will probably leak there even with a new gasket. With pan off the old bolt will need to be drilled out and tapped for a new bolt. Hope it doesn’t snap off flush, with pan off might be able to get vice grips on stub.
