Pre Lube my engine?????

[944freak]

Is there any other options to pre oil my engine before starting other than accusumps? I think pre oiling the engine is some really good PM. From what I've read/heard around 50% of engine damage occurs during starting the engine.

Make sure your oil filter has a check valve. I'm not a mechanic, nor do I have any hard data to back up anything that I say, at any time*, but it makes sense to me. You could take out your spark plugs every time you start it, crank it untill you have oil pressure. That takes a lot of the stress off of your bearings and it would probably greatly extend your engine life. But first and foremost, use a quality motor oil. I personally don't think viscosity really matters that much unless you live in Maine or Guam*, but I do know that cheap oil is false economy. I use Mobil 1, the one they recomend for older cars, it's middle of the road viscosity rating I'm thinking I'm good to go.

When I went back to Caly from Arkansas, I developed an oil leak somewhere in east Texas. When I pulled in at a station in Amarrillo (man I really hate that city, boy I tell ya what) to get gas, I was 2&frac12 qt. low on oil. No telling how long I had been driving at 80+ MPH on I-40 lower than the line on the dipstick. I firmly believe that Mobil 1 not only got me home all the way back to L.A., but it was several months before the inevitable engine falure caught up with me. 20k miles. I'm totally sold.

I had a 78 Chevy Luv when I was in H.S., and I put the cheap oil (parafin based) in and it spun a bearing in 2 months. I hope this helps

I'm already hooked on Mobil 1. I don't have any stories yet but I've heard quite a few. I know a guy who sells furniture and hauls it around with a Suburban. The thing has over 300000 miles on it, has never been rebuilt, Mobil 1 every 10000 miles. I'm thinking about installing a small accusump just to circulate the oil before starting.

Or only a switch to 1 wire of the coil, like antitheft switch. very cheap !

he was referring to removing the plugs to eliminate the compression in the cylinders which allows the motor to spin more rapidly w/ less stress and load on the bearings, the problem w/ cranking w/o the ignition spark w/ the plugs in is that you'll be spraying down the cylinder walls w/fuel washing away the oil leaving them susceptible to scratching while under compression.

Do you think its a good idea to get an accusump system then?

Thats a good point!

What I'm going to do is take out the fuel pump fuse and than crank away.

The point is to oil everything before forcing the pistons up and down the cylinder wall. The accusump will oil everything that gets oiled during engine operation by turning your key to the on position waiting about 30 seconds then start. Thus reducing the wear of your rings and cylinder walls.

Really? I thought you have to crank the engine so the oil pump sucks the oil and oil everything.

[Eduardo Castrejón Elbjorn]

Do we really need this ?
I believe that not

[944freak]

An accusump can be setup to pump oil throughout engine before cranking it over. We don't need this but I think it will prolong engine life.

'course with an engine that's well taken care of, 200k+ miles are not uncommon, no accusump nec.
