Air bubbles in my oil! No oil pressure.

[rob_e30]

That's the one.

[Vtec?lol]

^yes that one.

We just had this problem and solved it by priming the pump. There is an additional fitting on the side of the oil filter housing that faces the front of the engine. That leads directly to the pump. We use it for fitting a pressure gauge sender. Remove this fitting (allen head I believe), use a hose and funnel to pour some oil down there, turn the crank by hand (it should take some oil).

this one yes?

just for reference because

[Vtec?lol]

Ok, just tried to pump oil in that little hole but got nothing. I tried cranking it with the hole just to see if any would shoot out and it did but still nothing. I turn the crank over and over by hand while pumping and plug the hole up then bam. nothing.

UGH! AWESOME! I'm going to check this as soon as I get home!
thank you thank you thank you!!!!!

How are the bolts on the top oil pan? If they are loos the pan will shift letting air get sucked in.

Shouldn't be the case as everything was torqued to spec. I will check anyway thogh. thanks


Thanks for all your help guyss!

Thanks asschug (love your name lol) and ryan!

[Ryann]

You mean the one that you put on top of the bottle and push down to pump?

Yup.

[Dj Buttchug]

whatever you do dont use vaseline. use engine assembly lube.

[Vtec?lol]

You mean the one that you put on top of the bottle and push down to pump? good idea

[Ryann]

Good idea. now to rig something to shoot oil.

When I'm building an engine at home I use a power steering fluid hand pump that I found at an auto parts store. It's the same one I use to replace my trans. and diff. fluid actually.

[Vtec?lol]

damn this sucks.

[nando]

cool. would it be the same if i remove the plugs and force the Vaseline up the pickup tube while cranking?

no.

the air is inside the pump, that is the problem. if you put vasoline in the pickup tube it's just going to clog it.

[rjcaptsean]

The area the oil pickup tube bolts to the upper pan/ block is above the oil level in the pan. Is it possible you left out a gasket there or didn't get that tube fully seated and torqued down correctly? This sounds exactly like the "loose upper pan bolts causing the oil pump to suck air" dilemma these motors experience.
