Great job Stace. You really go into great detail which is awesome. Looking forward to your next video.

Happy new year stace, thanks for your videos this year, ive enjoyed them.

You did more work on the oil pump than most people would honestly well done! And good move sticking with standard volume over hi volume.

Any mods that allow better flow on these is ALWAYS USEFUL (Flow, not pressure, as that isnt possible by any means on these other than tightening up the bearing clearances, cam bearings particularly, and sleeving lifter bores etc) The relief valve mod is possibly the least important as it only changes the max psi before the valve opens, and lets face it, you are hardly ever running a street car Holden at max pump pressure, and even the stock 60/65psi is way enough for mild 308 RPMs) Yes that valve at 2:40 is the filter bypass. Good job, you are doing all the right things

Really enjoy this series and your attention to detail is outstanding! Looking forward to the next one. Happy new year.

Hi. Fishing around on youtube, I accidently came across your 308 rebuild. Not sure if you've fired the engine up yet, but I have built a few 308's myself and there is a much better way of priming that particular oil pump if you're interested. First of all, fill your oil filter with oil to the top and obviously stand it up. Pop in the two bolts that are hindered by the filter into the oil pump. Now with those bolts in their respective locations in the pump, screw the oil pump onto the filter. Now with everything still upright, fill the oil pump with oil and with a screwdriver, turn the pump gears as you are filling so that the whole pump is packed full of engine oil. Once complete, use a screwdriver to line up your oil pump tab to correspond to the drive shaft on the block. With the block on the engine stand, rotate the block to a position where the oil pump can mate at vertical to the mounting surface so that no oil is lost. You have already installed the two bolts tucked in behind the filter. Now just pop the other two in and tighten up. (dont forget gaskets). Now when you fire the engine for the first time, not only will the engine receive oil immediately, but the pump will prime itself in the process. Hope this is understandable and helps you out. Cheers

Great to see you back Stace, hope your Xmas was a good one.

Well done Stace

The Old Vaseline trick 🍻

Attention to detail is important with a Holden V8 oil pump. Looking at the one you have here it looks like a high volume replacement. Originally all the oil pump used to be an aluminum body and it would be a rare sight to find one today as they wore out quite quickly and caused other issues in the lifter camshaft area. I don't think the small pumps are still available anymore so just use a high volume. Dont mess around with pressure springs as if it is using a minimum 20 weight oil it will be fine. That is of course the clearance between the pump housing and gear tips is still in spec. The manual will have the measurement you only need feeler gauges to check. To much clearance here will cause a problem. Filling it with petroleum jelly really isn't something I would do with a Holden V8 but on certain other V8 engines it is important as they wont prime otherwise and will need the engine removed to sort out Mopar is usually a problem. The thing is it will settle out in spots that don't flush say inside lifters and dead end oil galleries. It never really goes away it just flushes around until it sits in the oil pan. Holden V8 I would just fill the oil filter pre start up. Just remove the coil wire for first start crank until it achieves oil pressure it shouldn't take very long. A bit of pure trivia My uncle bought a HT with one of the very first Holden V8's it had an alloy oil pump that used the same size gears as the Holden 6 It was recalled when it was about 4 months old for an engine replacement and one of the few things that were changed was the size of the oil pump as many had failed due to them being to small volume wise causing excessive wear throughout. A final note if you are rebuilding a Holden V8 they use a fiber rear main seal. What ever you do I would strongly recommend getting a decent rear main seal from somewhere like Chev off road and marine as the ones in the rebuild kits used to be to small and would ALWAYS leak. There is quite a procedure to setting a rear main for one of these engines they really need to be bedded in properly. Nothing worse than having to strip a rebuilt engine to replace a seal that shouldn't have even been in the kit as it was to small. I think COME still has a video somewhere describing the job.

that might be a jp pump i'm sure 308 and 253 pumps were alloy from factory

Vaseline trick pfft just crank it without fuel pump then attach and bam😂 if rebuilt oil it thru oil filter,I don't even do that on my vt 304 every oil change and I've never had a problem,330,000+km
