Broke something in the oil pressure switch

Should not be hard to remove the snapped off piece from the hole and install a new one. They are a tapered thread. The issue is that you need to remove it without generating any filings or metal shavings. A decent shop should be able to handle it without much fuss.

I broke the engine itself not the oil pressure switch.

Get an easy out at auto parts get it inside switch and try to back it out then replace the switch. It goes into the engine block.

If you actually cracked the cam housing that it screws into, getting a used piece from a salvage yard, would probably be the best bet.

Yes I cracked the cam housing. Did not know the name of it. Thanks. How hard is that piece to replace.

Not a bad job if you have the proper tools. It has to come apart just like doing the timing chain because you will need to retract the tension-er to get the timing chain loose.
Then once the chain is off you can pull the housing and check the replacement part for any wear on the cam or lifters. If they are worn (need to be measured very precisely) you will want to transfer the cam and lifters from the current part to the replacement, being very careful to make sure they go into the same positions they were in. With the mileage you have you will want to do a timing set while it's apart.

Price wise you would be looking at the replacement cam housing, full timing set (with sliders and tension-er), a top end gasket kit at a minimum.

Okay, thanks for the help. Got me a project for the weekend.

Thank you for using 2CarPros. Com.

Please let us know how the repair turns out as it may help others with similar problems.

Quick question will I need any special tools? Because I don't have any specific tools just basics. Like I had to get a special socket in order to get the oil pressure switch off.

There are a few special tools involved. Most should be available as rental/borrowed items from a parts store.
Get a copy of the book for that vehicle before you tear into it, there are specific steps to take in order to avoid damage. I suggest either or Alldata both have DIY access where you get the same information used by shops to do repairs. Runs 25-30 dollars for one vehicle for a year of access. Gives you the ability to look at the pictures and see how it's done.
