Sounds like the 1.9 is serving you well, that's good to hear.
I agree with Mark, I would slap it all back together.

Ok, after visual inspection, it appears that no major damage was done, so it must have been getting some oil. A couple of the rods have just a little play when I pull on them. I figure that it would be best to clean everything up, clean out the oil pickup, and replace all of the bearings along with the piston rings, fire rings and oil pump (since I don't know if I damaged it when I pulled it out). Any other advice??? I can post more pics if that would help....

It depends on your goals. You should really measure EVERYTHING (read the bentley). especially bearing clearances when the case is fully torqued, cam shaft end play, and since it's 1.9l you should check out main bearing 1 and make sure it's tight in the case and not moving around in the thrust direction.
This can all be measured with a few hundred dollars in tools. Micrometer set, dial bore gauge and dial indicator. |
Good idea. So when are you coming over to walk me through everything lol??? |

No comments on Plastigage, huh? there are probably hundreds of YouTubes but here's one with 6300 thumbs-up. I did NOT watch it. https://www.youtube.com/watch?v=q3pHb-qXZc8
Easiest, cheapest ($10?) minimal experience required, and direct to the crux of the matter is Plastigage®.
The only special tool you need is a torque wrench.
On a 1.9, can the connecting rod bolts be re-used?

Yep, 3k miles so far, up mountains and extreme heat. Still running great, but about a week ago I had a coolant leak due to bad threads on my expansion tank and ever since then, mpg has plummeted. Not sure what's up with that, but I'm going to start another thread about it. I think that I will def take my time putting the other one back together and do it right. Thanks. |

Plastigage is fine. But there are 3 main bearings you can't use it on because they're one piece. |

Oops yeah, I was focused on the rod bearings that have not been shown.

| I would probably plastigage the rods were I doing it mayself, but one could get a very good idea of their condition by just removing the caps and visually checking the bearing shell and journal. If there is not sign of heat, no sign of wear to or metal transfer from the shell, and the journal shows no apparent damage, it would be a good bet the clearances will be fine. |

And the "rod-drop test" before taking the caps off.

| Following this up....I did kind of slap it back together to see if it would run. But with new rod bearings and new lifters. Cleaned up the heads and the pistons. Followed the instructions in the Bentley for installing the dist drive shaft and adjusting the rocker arms and setting the timing. After installing in the engine, filled it with oil and saw oil filling up the forward most push rod tube at piston #3. Confirmed that the rod was seated on the lifter properly. Tried to start it and it is hard to get running. Did get it running, but it's running very weakly. Pretty sure the timing is fairly correct. Kind of seems like it's not getting compression or maybe fuel. Any ideas? Especially based on the previous no oil pressure? |

I'd recommend a compression test.

| Did you ever verify that you were on the correct TDC? Plug wires all in the right spot? Do you have a timing light? |

please don't take this wrong but there is much vagarity here that is easily rectified with a few instruments. simple tools, that as a classic vehicle owner who's able to tear apart his own engine you need to have....
- timing is 'fairly correct'. what does that mean? get a timing light and set it correct.
- 'seems like compression.." get a compression tester and test
- 'maybe fuel.." buy/make a fuel pressure gauge and test. do a flow test per Bentley or the Pro Training manual.
in one hour, you could have concrete data that will narrow your problem leading to a solution. otherwise, we're all just tilting at windmills.

I’ve assembled more engines than I can count. Don’t recall slapping one together. I agree with the above advice and recommendations. I’ll add that adjusting the valves seems to trip many beginners up on a Vanagon engine. I’d recommend zero lash till you get it running. Then readjust using the recommended preloads. This step is not necessary for someone experienced. That you spent quite a bit of time figuring out where your oil pressure went would indicate you are more at the beginning of the learning curve. Good news is you are learning. |
