Im prior to the first start on the rebuild
I want to get the Valve train hardware in the bus, before my engine stand is needed elsewhere. Just about everything else is done now.
Even with getting the engine itself together, Im not going to be ready to start it the first time until at least next week. Should I set the valves and button it up as normal or should I leave the adjusting screws slack and wait until Im closer to completing the whole thing? I'd like to set everything on the stand while I have the better angle to approach it all
I have bled the lifters and have them submerged in oil. All the write-ups and searches only talk about older ones or engines that have been sitting for extended times. I assume I should be good for a week or 2 under pressure.

you should be Ok.
When you bring up the engine the first time there is likely to be air in the oil. I find it is easiest to get oil pressure the first time by removing the oil filter and putting a pan under the engine. I crank it without the plugs in for about 2 or 3 seconds which is enough to build pressure with the oil filter off. Use a remote starter or something cause oil will come out fast. Then put your filter on and go ahead and crank it with the plugs out. You should get oil pressure right away. Put the plugs in, attach the wires and you are ready to go. _________________ "Most people don't know what they're doing, and a lot of them are really good at it." - George Carlin |

Every hydraulic lifter engine I have built I pumped up the lifters before I put them in and adjusted them once they were in. I have invariably found that after you run it for an hour or so, you need to adjust them again. Bench bleeding them is no real guarantee they are pumped, unfortunately. _________________ air-cooled or nothing for me

I agree with SG except, i fill the oil filter and put it on the engine and also fill the oil pressure switch galley with oil. prior to starting. reinstall the O.P. Switch .crank the engine overuntil oil light goes out and hook up the ignition wire to coil. \
Restart engine and check for any leaks with idle raised approx. 1500 rpm
Even with lifters (pre-lubed don't be surprised if you have a couple that
have not pumped up.
Snug the valve adj. nuts so they will be easy to readjust after run-in. _________________ V.W.owner since 1967 |
