1996 850 2.3T blown #2 Rod at 208k

Before you patch, it you might want to rotate the Crankshaft to determine if what you see through the hole is a Connecting rod or something else that moves. Maybe stick a screwdriver in there and see if it a loose part. A compression test on the cylinder(s) closest to the hole might produce useful data.

if you are going to sell it let us know. Im in nj.

Thanks for the input folks, it helps a lot. I stopped by my Volvo tech today and he had never seen anything like that in his 13 years of fixing Volvos, so I guess I feel special lol. He also recommended the JB Weld "temporary" fix, to first see if it runs OK. If not, then it's onto bigger repairs I guess (and no, not gonna get rid of her just yet). I do like RickHaleParker's idea of turning the crankshaft and looking to see if that "eyeball" moves or if anything else changes inside the hole. As far as JB Weld, I know they have different varieties; do you recommend any type over another, and what kind of "screen" material would I use to cover the hole to act as a framework for the epoxy?

Thanks again!

I mean, you might be lucky... but if it lost oil then "died on the way home", I seriously doubt the car just shut itself off without some real damage being done. The car doesn't know if it has oil in it or not. The low pressure light is only an indicator.

Yeah, I'm not holding my breath on this one. It's not my daily driver anymore so I'm not in a big hurry to get it back up and running (read: I don't have the money to throw at it right now). Lesson learned about lending my car, though. Won't be doing that again...

Window screen, it will provide a framework for the J-B weld to setup on. You could probably get a scrap piece from a hardware store that cuts to order.

Cut the screen to fit over the hole with a hangover on the lower edge. The overhang will give you two surfaces for doing a fillet on the bottom of the pan.

Mix up a small amount of J-B weld and press it into the screen. Place the screen over the hole and let it cure. You now have a framework for the rest of the J-B weld and you don't need to worry about pushing J-B weld up into the engine.

I prefer J-B Weld Original. The Quick Set make for a rushed job. The Steel Stick, never had much luck with it. You don't need the Water Weld or the J-B Weld for plastics.

I wouldn't spend a second on any repairs yet, certainly no JB Weld, until you finish the simple diagnostic things. Before you check compression, pull the plugs and rotate the crank by hand to check the travel of each piston. Do all pistons get all the way to the top like they should? If not, you have a broken rod, which seems most likely.

This sounds just like what happened to 98v70dad about a year ago, and in the end after 3 long threads where there were way too many armchair opinions leading this way and that (hey we can't help ourselves! It's easy when someone else is doing the wrenching!), it was a broken connecting rod. First thread here, probably too much effort to find and read all 3 threads:

As above...

- JB Weld as a temp fix, add cheap regular oil, oil filter.

- Don't run engine, do compression test. If a con rod is broken, then you don't have compression in that cylinder.

Either new engine from reputable seller like Erie Volvo, or junk the car (a 200K car is worth $500) and buy a "new" S60 or 2004-2007 V70.

Its interesting to see how bad people want to fix the hole ignoring the larger problem. I wonder if this is a window into why the world is doomed.

Nobody is ignoring a larger problem. It has not been determined that there is a larger problem.

A: We know that the lower end on these engines are highly dependable, even a engine out of a salvage yard is a good bet.
B: We know that a good engine out of a salvage yard is a lot less then rebuilding a lower end.

Now see if you can reason it out.
