Guys, I really need the torque specs for the bottom end: rod & main bearings, oil pan & pumps bolts, etc. After a lengthy search I found my Haynes manual--unfortunately, it was out in my backyard. I just blew all my funds on the bearings and gaskets, so I can't replace it yet. Please???

Thanx

Thanks Peter, you know you rock right? BTW, I coating the bearing journals (the thingys that you press the bearings into--i think that's what you call them) with assembly lube. Should I worry about that? Could that possibly help spin a bearing down the road?

I'm still trying to find out more about the 16V VW head and the Audi 7A, AAN, or 3B motor, but my weekends keep getting sucked away by girlfriend, mom, appts, etc. . One of these days, though...

Thanx

Not sure if I am reading your post right or not but I assume you basicaly lubricated the back side of your bearing shells, both main and rod bearings. Generally this is not a good idea but not for the reason you have stated. To make my point I will relate a story from my dad. He had a freind who did a home rebuild on his old pickup. During the procedure he dipped all the bearings in engine oil as an assembly lube. After assembly and installation he found the starter would not crank the engine at which point he called my dad. After some quizzing of his freind they ended up pulling all the bearings, cleaning them up and lubing them properly. This fixed the problem. It seems the lube was taking up clearance on the back side of the bearing and creating too much crush. I have since heard simular stories from other mechanics though I have never experienced myself. If you can crank your engine, with the sparkplugs removed, with less than 20lbs torque you may be alright.
