Leared a bit from this one mate. Goes to show how taking a bit more time to prime the pump, check the timing properly and having a bit of a fiddle before firing it up makes it all worthwhile. Awesome
Cheers mate as they say preparation prevents piss poor performance. Going through them like this doesn’t give you the heartache of destroying a motor on Initial start up when it doesn’t pick up oil pressure and starts knocking straight off the bat.
Ive heard alot about using grease or Vaseline in the oil pump but never done it, but what I've always done is with the two halves of the pump bolted together with the two little bolts, I orient the pump on a bench in the same position as it would be sitting when bolted on to the motor. I then pour motor oil into the gear chamber and fill it as much as it will hold, I guess it would be around 80% full. You don't need the oil filter or the pressure switch on the pump to do this. I then gently take the pump to the motor and mount it in place taking care not to tip the pump and allow the oil to spill out. Then with it bolted up fitna new filter and the the pressure switch. The oil in the gear chamber will be enough to prime oil from the sump up the suction pipe and into the pump. This always seems to work, as when you think about it this is the exact same scenario that is created when you drain the sump and remove the filter when doing an oil change, the oil drains out of the suction pipe but it cant get out of the gear chamber and it primes straight away after an oil change. I worked for many years as an industrial hydraulics fitter doing system troubleshooting and figured this out myself after doing an extensive study into the flow paths and workings of the Holden v8 oil pump. I reckon this is how Holden engineers designed it to be primed. Give it a try if you get a chance. All the best 👍
That's a great idea instead of using vasoline that I've used don't really like it, the oil light on my dash flickered with vasoline never used an oil pressure gauge, but thanks for your tip will try it on my next build
Great vid very informative, can you tell me if a motors been sittingvfor 4 years do I have to pour some oil in the cylinders and turn over by hand 1st so not to damage the bores ? Cheers
Good question, in a short answer and not knowing how it’s been kept I would say yes it won’t hurt it to do so. I didn’t with this one. But it was kept in cover and all the plugs were left in. I’ve seen people use trans fluid down the bores and left for a bit of time. Just have to make sure you get it all out before you put the plugs in so you don’t wet the plugs when you go to crank it
Good video, Just one question if that was a new rebuild with new cam you wouldnt turn it over like that to get oil pressure up before starting or would you?
I would and I have done this, when my motor was built in my other car we packed the oil pump same as this, and wound over till it had oil pressure. You have to remember when a new motor is built and new cam is installed everything is lubed with assembly lube on mating surfaces. So those areas aren’t dry, but it still needs to be able to pick up oil pressure before trying to fire it. Oil pressure overrules everything else IMO. But that is my opinion and how I’ve been taught. Depending on who’s building your engine they may do it differently, and I would follow their process incase failure does happen and it doesn’t void your warranty.
I was taught to confirm oil pressure with no plugs in. Then safe to fire if everything is in order. Old boys showed me priming oil pump through dizzy shaft before start. In old Ford v8s.
Hi Tony here Barry’s son in-law been waiting for this vid. Good to see you got it going I’ll show Barry he will be rapid
Cheers mate, He was right about it. It’s a great little running engine 👍🏻

Hardened valve gear is a good idea because these engines didn't have a long life in this area (oil supply)
Can you show us your starter button set up/wiring please
If and when I do another one of these types of videos I’ll run through the starter button. That’s if I can find another car to buy!!
Hey Bro.just subscribed Good vids. I love Holdens . Just wondering.. is that a 253 engine or a 308.
Thanks for the support man, this one is a 253.

In old Ford v8s.
Maybe a WB ute. They were the first along with VC to come with a blue motor.
They did come in wb. But this one’s engine number comes up as commodore.
@@V8JakeC Thank you for your message. I like your video 👍
