Thank you all for the first hand accounts and horror stories. It’s settled: new engine time. I have travel plans to New Hampshire in the summer as is, a quick detour to Long Island is no biggie. And while yanking the thing out will still be laborious, it sounds like I’ve got help in many corners. I’...

Hello again. An interesting proposition has been brought to my attention. Considering I'll be removing the engine and rebuilding it, trying to get new bearings and all, it's come to my attention that, if the crankshaft is undamaged, the pistons and therefore bearings can be removed without actually ...

A thrilling update: as I went to do my test this evening, for a moment, the engine would do nothing. I could hear the starter attempt to move it but no cranks. Then I let it sit a minute, or maybe 30 seconds, and tried again. Slow crank, to start. Idled a moment, revved and the noise increased with ...

Well, I would try to do as much of this as possible myself… but I can’t balance crankshafts and such… so… shit… It sounds like I’ll be buying your engine, taking the original out and throwing yours in, and then slowly… very very slowly… getting the original one rebuilt bigger and better to one day t...

I have two questions, out of morbid and horrific curiousity. 1.) Will doing these tests of revving and then taking my foot off do any more damage than I already have? Based off the brief descriptions I feel safe in saying rod bearings. But one last check would be good. 2.) how rebuildable is this? I...

Higher pitched clattering that increases with revs is usually rod bearings.

Sounds like that. Has a squeaky wheel sort of sound. Had hoped it was a pulley or something stupid but… it’s probably not. Granted, I’m a little afraid to run the car and damage it more based off this noise.

I fucked up this weekend, and had lots of fun doing it. The video below will likely explain: https://youtu.be/EgP2hEEmILc?si=jxxZgmhdFdOXDdO7 Lots of scary words like “Rod knock” and “camshaft” and “spun bearings” have been thrown around. Here are the facts in order: - I spent the weekend thrashing ...

The circlips are often improperly shaped on aftermarket axles. Replace it with one from an OEM or GKN axle There is another trick , use heavy grease to center the circlip on the axle when you push it in. You need to hear the click as it engages or it is not seated. The transmission splines are desi...

What was the issue with the shifter cable and what was your fix (PVC pipe)? My shifter on my 2000 S70 seems rough/sticky compared to my 93 850 and I'm wondering if it may be the cable. No 2nd 4th or reverse, the cable guides were totally worn and would buckle. The pipe and duct tape is just a brace...

The transmission spines MIGHT be OK if they are harder steel than the axle spines. Get a bright light, good magnifier, get your head down there and do a close inspection of the transmission splines. If damaged it will only be the outer edge as this is where your axle ran. Careful work with a file m...
