Hi
Fitted a new oil cooler and pipes to my B, which hasn't been started for about 6 months.

Before starting the engine should I :-
A) Undo the pipes and pour oil thru the new cooler until its full, sort of priming it ?
B) Take the plugs out and crank it, keep topping up with oil until its fully charged
C) Just go for it and trust to luck.

Any one got any thoughts on the best way to approach this ?

I'd fill the oil cooler and hoses as best you can. It is easy to make a mess if you're not careful.

Pull the plugs and spin the engine until you see oil pressure starting to build.

At least - that's what I did on our 72 when we rebuilt it.


My opinion - you want as little time with no oil pressure as possible.

When I installed mine I did the following to fill the hoses and oil cooler:

* Disconnected the rear hose and hold it high enough so that the fitting is higher than the oil cooler.
* Place a funnel into the opening
* Keep adding oil into the funnel until it will take no more.
* Remove the funnel and reinstall the hose without making too much of a mess.
* The oil cooler should now be full including the hoses.

the oil pump shoots so much so fast that if you disconnected hoses and directed them properly, you'd get the neighbor's windows oil coated inside of 10 seconds.

First, I would fill the presumably new oil filter with oil.
Then I would Don Trembly the oil cooler.
Then I would crank the engine a little with rear oil cooler line off to verify the oil pump is primed.
Then I would pull out the plugs, connect oil lines
Then I would crank until I see that oil pressure builds.
Then I would replace plugs and crank to start.

Yep.
You guys are overthinking this. Just hook it up and start it.
If it's easy and you want to fill the air void by funneling in some oil before you cinch down the fittings that's OK.
This is how our projects get sidelined. We worry so much about stuff that it keeps us from driving and enjoying our cars (and I am a victim of it, too, so no dis or putdown intended here):
We are victims of the 3 P's - Perfection, Procrastination, Paralysis. You end up getting nowhere.
Just go for it! My 2 cents.

Knowing how car production lines work the factory would have filled the engine with oil, started it then topped up the oil. They wouldn’t have time to fill tho oil cooler first.

So you only needed to take of the back hose, not both ?

Just pull the spark plugs and turn it on the starter with a strong battery until the oil pressure gauge registers pressure. Then start it as usual and watch the gauge for the first 30 seconds or so. If all is OK, check the new oil cooler and hose fittings for leaks.

B was once enough for me with a new oil cooler in place, but I also used this method twice when taking the engine out for a clutch job, but keeping the oil cooler filled up
However I must admit putting the TSL additive to my engine oil, which can keep the bearings alive even when almost running dry for a short period. eye rolling smiley

Simply crank the engine over with the choke in. When the oil pressure gauge starts to move, you're all set. RAY
