Reinstalling my engine on 03 Discovery and have these two left over. Head is 10mm and 11mm and 1” of thread. Can’t figure out where they go. Head is grimy so thinking external

 

Knock sensors or motor mounts? I can remember grabbing an 11mm socket...but don't remember exact for what. I'll be out in the varage today, I'll report back if I can come across these bolts.

Negative ground cable on driver side head and metal heater core pipe to passenger head.

or missing head bolts...

 

Yeah, kind of thought about the ground cable after I posted. I know there were two unusual size wrenches I used during the removal/install of my engine last year. A 11mm and a 14mm. Now, that I think about it...l believe it was the motor mounts bracket had the 14mm headed bolt. Remember one of the odd sizes being below, because I had to get up off the creeper...and I hate that at 57 anymore...lol.

Usually, you can grab a 8mm, 10mm, 13mm, 15mm, 17mm, 18mm and 19mm...socket and wrench...and disassemble about any foreign car. It's odd when you run into 11mm, 12mm, 14mm or 16mm.

Anyhow, if you only have two bolts left...you must be pretty close to go time. Congrats, on the engine swap.

Thanks and great thoughts. On both the motor mount top hole and the
Heater pipe outlet I struggled to figure out what bolt to use. I used some short grounding type flanged bolts about 3/4” long on those spots thinking these were too long. For at least one of those I dipped into my tool box

Maybe tranny cooling lines clamp to engine. Not sure
