priming the lubrication system?
Hi all, I posted this on the 1948 -1960 sub-forum, but, just to cover the bases, I'm posting it here as well.
I've just put the 215 motor from my 53 back together. It has been 28 years and 60,000 miles ago that I rebuilt it. Everything looked fine 'cept the timing belt was a bit loose, so I replaced it. The brearings are good enough to keep using for another ten years or so (at the rate that I plan put on miles). Also, I squirted the stock green paint on the block to pretty it up. Now, here's my question: is there a way to somehow put the engine oil back in the motor in such a way that I can be sure all the parts are well lubricated before I start it up next spring. If I "injected" a couple of quarts in through the hole in the block where the oil pressure sensor screws in, would this fill up all those nooks and crannies in the crank? I did put the motor back together using liberal amounts of assembly lubricant. Just asking. I never "injected" the oil in any motor before, and I've never had any problems that I'm aware of. But this time it's going to be sitting on a stand for about six months before I'm ready to crank it over.

My buddy is building a street munching 460 with a blower. He has lots of high dollar parts in it so he too is worried about start up lube coverage. He told me that there is a machine that performance guys use that circulates the oil throughout the engine before they start it. So it sounds like you might be on the right track. John

Myself, I used a drill to turn the hex type oil pump shaft that is normally run from the distributor. Make sure to go in the correct direction...
I agree. I would NEVER start a fresh engine without preoiling. If you used the drill method, I'd keep at it quite a while to make sure it's all through the engine. You should see oil at the rockers, pushrods, etc...I hear the machines are even better, but I don't have one...BTW, to speed up things, I would prefill the filter if possible. MK

pull the sparkplugs and crank it over until it registers oil pressure on the gauge (hopefully you have one). If you dont have a gauge, just keep cranking it until the starter motor sounds like its really starting to bog down - by that time, oil has circulated through the galleys, and you should be good to go. Ive started plenty of brand-new engines like this - anywhere from stock to full race, its all the same.

Flat4vw,
I'll give that a try first. It's the easiest. My oil pressure gauge does work. It didn't occur to me that I would get any kind of noticeable pressure reading at such low rpm. I'll look to see if oil reaches the rocker arm. I assume that if I see that the rocker is getting oil, then the pump must be pushing oil through all the other passages.
Thanks, jvmcc

no prob. - even if you gauge is working, listening to the starter bog is a good way to tell when theres solid oil pressure everywhere. It should spin over very freely and fast if there isnt any oil pressure, and once the pressure builds up, it will start to slow down considerably.
