i got a little excited toward start-up & took fewer photos than i had planned to. i will snap some more shots of the completed installation when i do some more work. until next time.......

When I put new tubes/spark plugs in, I missed about 3 proper "snaps", that could most definitely be causing a problem with oil leaking, but it wouldn't affect idle...

i had two bolts that actually came out okay, so i measured the depth of the holes & tried to match that with my drilling. i believe it was like 31mm.
when drilling through the bolts, it's easy to notice when you're at the bottom. there is a gap between the end of the fastener & the bottom of the tapped hole; you can feel when the drill goes through the last of the steel. still, though, better safe than sorry!

Ugh! Extracting bolts that have bonded to the block is probably my least favorite job. I screwed it up more than once in my youth too. At least your motor was out where you could get some elbow room for turning wrenches and it sounds like you got good results.
From the looks of that motor I bet it saw duty on winter salted roads many times.

Here's a link to my adventure with broken exhaust manifold bolts:

Worthwhile reading for anyone contemplating removing exhaust manifold to cylinder head bolts.
Regards, Maurice.

Maurice, that line from the top of the oil cooler is a vent to the surge tank to release entrained air from the cooler, which happens to be the highest point of the cooling system on the engine. By getting rid of the air, the laminar flow exchanger works very well; with trapped air, its thermal efficiency falls off very quickly....
