So I got the OEM sensors today. Everything was fine, I know where the cam sensors are....only problem is that I CAN'T get the friggin' bolt off the first one (the one closest to the front of the car, with one bolt). Looks like my wrench won't exactly fit in the crowded space. Any tips on what to do?

 

Not sure how big your wrenches are but, might have to pick up a smaller one from harbor freight and hit it with some pb blaster before you go at it. Fwiw mine came off really easy

 

Yes, get a socket set. Much easier. Those two spots are kinda tight, especially with the small amount of overlap/ledge that the valve covers sit on.

 

Wrenches? Those are like ancient technology and are only used as a last resort

 

As others have said, use a socket.
You'll round it off trying to get a wrench on it and not pulling exactly straight.

If you're going to do any work on cars you need a socket set. The bare minimum would be a 3/8" drive ratchet, sockets from 8mm to 19mm and a few extensions of different lengths.

Eventually you'll want a 1/4" drive set too and deep well (long) sockets in both drive sizes.

If you have a decent sized local flea market you can piece together a workable set for pretty cheap.
