Changing oil...Let it drain overnight ?

Does that work.....just crank it a bit and stop...crank some more and then stop (not going all the way to firing)....I will try that today for kicks......I mean for pre-oiling...that may be the answere but starter will then get a work out

OK...on a 91' I cranked it over maybe 4 or 5 times without starting (did this six times). Then fired it up and oil pressure was almost immediate.
Same on 90'. The oil pressure on a regular start (after sitting over night) comes up in a second or two later and I am thinking I will stay with "standard" starting practice and "standard" oil filter changing practice. That is to say......just turn it over until if fires and let engine sit overnight before changing oil filter with new dry filter.

That method of changing oil filter on the LT5 is cleaner and with less mess than on any other engine I have ever changed oil filters (the filters that are horizontal or tilted up which stay full of oil and capture oil above them that creates the mess when you remove the filter).

Don't think its necessary to get full pressure before ignition. Just looking to get some oil into the system and give it a head start before actually running the motor. Try that even now while car is lying dormant for long periods. I look to start the car during the winter at least once every 3-4 weeks altho I wait for temps close to 40 if possible.

Could probably be done with the LT5 as well.

Yes, but of course you should also remove the spark plugs to reduce the compression load on the crankshaft! You also get a faster cranking speed.

Actually I have done this before on new engines that I did not have the oil pump priming tool (or as mentioned, on distributorless engines like the 3.8 that use the classic style sump mounted pump).

Hmmmm.... Kerful Mike & Dom, or we're gonna veer into a formal (and good) mod discussion about cutting off ignition/fuel so as it would be possible to turn pre-oil the motor after sitting for and "extended" period...

You will probably not see any oil pressure register on the oil pressure gauge just from starter cranking. But......you will fill all the oil voids with oil. Once started the LT5 oil pressure jump to full pressure will be almost immediate. Like with my experiment this morning on a 91' and a 90'

How about an Accusump system?
They're pretty straight forward but I've never
seen one on an LT5.

This is what Canton Racing says about their Accusump System.
I am no so sure about the wear and tear when I start
I would think if this were a serious problem, GM would have incorporated a Pre-Oiler system

Did you know that most of the wear and tear on your engine occurs when you start it? Solve this problem by installing an accumulator, which is also a pre-oiler! By circulating oil throughout the engine before you start it, you can avoid the damage caused by dry starts! You'll also get added benefits: You'll increase your oil supply and, because the oil in the accumulator is under constant pressure, if the oil in the pan runs away from the pick-up durring hard cornering, the oil in the accumulator will continue to lubricate the engine! You'll be double protected. It's a huge return for a small investment.

I am thinking of installing this.....

Do you have any more of them????

Cool thanks!!!
