Vass. packed oil pump

[87GN_ponykillr]

Just wondering why everyone shames on packing the oil pump with lube? Does it hurt the turbo? Any other reasons?

I had good luck back filling the OP from the cooler line when I did my timing chain.
fyi

While petroleum jelly has a wide variety of uses it has no business being in your oil pump IMO.Unscrew the oil sending unit and put a nipple in it's place temporarily and connect a piece of hose to it about 2' long.Get one of those spout tops like they put on rear axle lube bottle and hook the other end of the hose to it.Your oil bottle will screw right on,flip it upside down,poke a small hole for air at the top.Let a whole quart drain in there now,it will not leak if you have good connections a few hours later it is fully primed.I suggest spinning the oil pump with the drill next to verify pressure on the gauge.Make sure you are spinning it in the normal direction of rotation(clockwise).

petroleum jelly

I am sure the experts will tell you something else but I have been using petroleum jelly for more than 10 years on brand new race motors. I just had my motor freshened by T A Performance and and the oil pump is packed with petroleum jelly. They did several major oiling mods to the engine to make it live and they use petroleum jelly to prime it. Hope that sets your mind at ease.

I see no problem at all using petroleum jelly for oil pump priming, if that's you choice of methods available.

I use Vasoline in every motor I build, never had a problem, ever. They always prime immediately as well. The keyy to getting all the vasoline out after you have broken the cam in it to drain the oil while it is still very hot. Drew

I never claimed to be an expert and I'm not running 9's, but you gotta wonder if it is a good idea with the cam break-in being so critical on these motors if breaking a cam in with a handful of vaseline in the oil has anything to do with the usual #3 wiped lobe.Don't you guys spin the oil pump to pressurize the system first? Also,if vaseline pushes out and replaces assembly lube on the bearings while the motor is cold what happens when you finally fire it with vaseline coating the bearings for that first few critical moments? Maybe for a race motor ok but a guy on a budget that wants to get 100,000 miles out of his rebuild should probably inconveinience himself a bit and prime with real oil.It's not like it's a big hassle or hard to do or even time consuming,so why the vaseline?What advantage does it provide? Sorry to rant but it just seems to be the 'logical' approach whatayathink

Sorry, I should have clarified, I pack the pump with vasoline and then prime with a large 1 horsepower Drill for approximately 10 minutes, with a second person tuning the crank very slowly with a breaker bar, this assures you have oil to all parts of the oil galleries and even through the pushrods. The only reason I pack the pump full of vasoline and then prime is to get the prime started, after you prime the motor for 5-10 minutes, the assembly lube/vasoline is gone. and replced with regular motor oil. This does not remove the moly assembly lube used on the lobes and bottoms of the lifters as that is only lubed by what slings off the crank anyway, hence the main reason you prime the engin and bring it up to 2500-3000 RPM's immediatly and stay there for 30 min. or so when breaking in a new cam/engine. Vasoline is nothing more than petrolium Jelly, it blends completely with the petrolium based engine oils. I have built both types of engines by the way, ones that have lasted well over 100K miles as well as a couple in the low 9's. all have been packed with vasoline and then primed as I said earlier.

PJ Prime

I've used vasoline for 17+ years when rebuilding engines under warranty @ G.M. dealer. If something goes wrong I have to fix it for FREE!! People beat their cars hard. I would not hesitate to use it. Any way you prime as long as you prime! Vasoline stays where you put it, disappears once hot, and helps pump draw oil when engine/pump is first spun. My $0.02
