Agree ,with the reluctor setup on a DOHC the engine has to find the reference at cam and crank and it probably checks it....


Also an engine were they were worried about cam seizure on cold start up(thanks to a BG employee starting then at full throttle), alittle pre-oiling is probably build in....does not hurt to get the pressure up before it fires.

It startles you when it fires instantly upon turning the key, but it does happen from time to time. I always like it better when the engine cranks for a few seconds so it can get oil up top.

Rubber Liner Thingy on Ebay

I kind of like to spin the crankshaft with the starter a bit as the oil circulates just a tad before it revs up.....I forget exactly when the oil pressure starts showing on the gage but I think I recall it showing a tad when doing a compression test after a few crankshaft revolutions.....

That's what I'm wondering here now - maybe the coding is written to spin up and get oil pumped, BEFORE ignition to any cylinder - such as #1 :confused:


ed.:
Brett beat me to the punch here; immediate startup, when #1 'fire' happens to be in 'X' position in rotation???

I thought there was a four second delay to firing up.

Mine also starts instantly when hot, I wonder if it looks at a percentage of oil pressure and temp also. And if it is just before the sensors signal the ECM.

Mine generally only does it upon the first start of the day....when it happens, which is only now and then. I generally start the car every day just to keep oil up top.

Re: Long cranking
 
I don't start mine every day, but when I do start it I also let the pumps run a bit before I turn it the rest of the way to crank it. I had to do that on my BBC in my Nova or it would stumble bad when started and sometimes backfire thru the Carb.... So I kinda got used to doing it...:p
Mine cranks for 3 or 4 seconds as well.

Speaking of oil pressure at start up, anyone
ever use an Accusump?
Where would you plumb it in?
Where would you put the sump/accumulator?

I would plumb it into the oil filter adapter (maybe oil Cooler Lines).....but would have to check on that for sure first.

I was working on a Billet Aluminum Remote Oil Filter Adapter a while back and had it sized to fit under passenger side headlight (I think I was relocating the coolant overflow). The Design was for Dual Oil Filters. I was working on a System that would NOT Drain Back but still easy to change filters without a mess.

That Remote Oil Filter Adapter I Designed fit in place of the present Oil Filter. Had SS Braided Oil Lines going down to the Billet Aluminum Remote Dual Oil Filter Housing Adapter. Now that I think of it......I think I left the Coolant Overflow in place and positioned the Remote Oil Filter Housing Adapter where my Secondary Pump was previously located (Since Removed).........Or......moved existing Coolant Overflow Tank where Vacuum Pump was located and positioned Billet Dual Oil Filter Housing Adapter in place of Coolant Overflow Tank. I have the specs ;)

Oil Filter Adapter fits on existing Oil Filter Housing
