Well I'm getting ready to fire my new motor after complete rebuild. I packed the oil pump with petr. jelly and filled the oil filter. With the oil cooler adapter off (just the full oil filter on) I spun the oil pump with a drill and it started to pump oil out of the turbo oil line and into an oil jug. I figured I was laughing. So it's been a couple of weeks, in the process I filled the oil cooler and installed the oil cooler adapter. Engine is now in the car, and last night I cranked it for the first time with the starter and I have little or no oil pressure registering on the guage. It moves but that's about it. How much oil pressure should I have on engine crank? I also thought about pulling off the turbo lube line just to make sure the system is still primed. I cranked it 3 times for about 20 or seconds each time.
Thanks
 
I am not an expert but when I crank my engine (without starting it) it just barely registers oil pressure on the gauge (autometer). Not enough to read but I do see it move a little. It immediately jumps up past 50 once started.
 
Take the plugs out if they are installed
If you have a hot wire to the fuel pump unplug it
On my new engine after hooking everything up (remote oil filter setup)
I cranked 30 sec coulpe times had at least 60PSI on the gauge in the car then installed plugs connected hot wire and started right up
 
Well I removed the spark plugs and took off the turbo oil line and cranked it and nothing came out. So I took off the oil filter and it was about 1/2 full of oil. I tried to top it up, but likely lost as much as I gained reinstalling it. Cranked twice for about 20 seconds each and still nothing. Any thoughts? I'll search on priming as well. But does anybody know which line on the oil cooler adapter is the suction line? I thought perhaps I could take that line off at the cooler, dump some oil in and put some air pressure on it to force it into the pump?
 
Once the vaseline gets warm, it liquifies. Pour oil directly into the pump with a funnel and hose one of the cooler lines. Pour in about a third to half quart. Don't just prime the pump. Prime the engine. You need to go in through the cam sensor hole and turn the pump with a hand drill until oil comes out of the pushrods.

How long did you crank it with no plugs? It can take a minute or more on the starter to pull the oil up amd get it pumping.

Best to pull the Cam sensor and use a pre-lube tool on an elecric drill. I have NEVER needed to back fill or use jelly in the pump.
 
I have always primed the pumps with Vaseline.

Get the drill back out and make sure you're pumping through the filter and cooler.

The starter turns the oil pump at about 150 to 300 RPM at best. Your drill was probably doing 2000 RPM.
 
I just did a rebuild, and poured some oil down the hose on the output side of the pump, put the filter on and then primed the engine using my oil primer tool. Spun it up with my drill for about 15 to 20 seconds to make sure I have oil going up thru the pushrods (make sure you put a shop rag or something over the pushrods, or you will have oil squirting all over the place) then I put the cam sensor, and valve covers back on, adjusted the cam sensor and fired it off. :biggrin:

Ok, well I pulled what needed to come off to get the cam sensor out, and removed the oil pump. Cleaned everything out, packed it with Vasaline, filled the filter and cooler, and then tried the drill. It was pissing me off, I couldn't get it to hook right. So I put the cam sensor back in and cranked it over. After about 10 or 15 secs the guage started to rise :) It went up to 55 lbs :) So I did it about 5 times to make sure oil should be flowing everywhere. So hopefully it's all good!
 
just primed mine w/ no vasaline packing after new motor install.....I disconnected the top oil cooler line from the radiator and submerged the end of the line in a quart of oil. then i ran the cam dist. counterclockwise and it sucked the quart of oil up in about 30 seconds. i then reconnected the top oil cooler line to the radiator and spun the cam dist. clockwise while checking my oil pressure gauge. instant oil pressure!
