No Oil Pressure - Page 4

SlowWhite · 08-09-2004

Well believe me that's my plan. But if the motors shot it shot.

Before we tear the motor apart I'd like to do a Compression test to see where it's at.

if there's no compression would there be any point to tearing the motor apart?

If the compressions still decent then - we'll test the oil pump, and/or swap out the oil pump. I have the spare one so it's not like it'll cost me anything.

I'm just looking to last till winter (novemberish) - then I can take the winter to figure something else out.

Ok yesterday the oil pump was spun with a drill but Nothing was happening.

There was no grinding sounds, or anything. But the oil also wasn't being pumped?

So what does that mean? is the pump blown or is the system not "Primed" so to speak?

Compression test was done before taking things apart:

(I forget the exact numbers but they were something like this)

142-160-185-152

Not the greatest but hopefully still able to get me around till winter.

Anyways what are your guys opinions on what's going on? today I was going to have the oil pump replaced. But do you think there is anything else it could be?

Thanks, I couldn't remember.

loosing a bit of compression there.. .. maybe its getting too lean in that cylinder.. check your plug and or injector..

Injectors are brand new, and plugs are changed basically every 2-3 weeks.

(in this case they are brand new since my cars only run for 2 weeks, and we swapped them out on the Dyno)

Have a few replies from the guys on DSMLINK.com

1)
I wouldn't start the motor again....

How did you spin the pump with a drill? You have the timing belt off right? I would use the drill method to get oil flowing before trying to start the thing again...

Pull the feed line from the turbo (it's off the filter housing right) and try spinning the pump again? See if you get any oil.

You may also want to try taking off the pick up agian, making sure it is not some gasket problem or something. Also putting some grease on the oil pump gears, trying to pack it like you do when you assemble the oil pump on the front case would not be a bad idea. This would aid in suction...

Did you change the oil filter? I vaguely remember something about Fram or someone having a problem where they shipped some filters that were missing holes necessary for oil flow.

You should be able to hear the drill "load up" as oil starts to flow as well.

Definitely do not start the car again until you resolve the issue.

You can use a vaccum pump to prime the motor from the filter housing if you don't feel like pulling off the front case to grease up the gears. The gears should still be plenty wet though with oil which is what is baffling....

I used rich's method as well as priming the oil pump with a gear. Pump it through the oil pressure sender via a clear hose and a hose barb.

Put 2 quarts into the pan via the normal method, and pump 3 quarts via a fluid pump.

You should see oil coming out of the rocker arms. Pull plugs + mpi fuse (or turn fuel pump off) and dry crank the car until you see oil flowing through the rockers and until the dummy light on the dash goes off. Do this a few times, but it only took me what sounded like 3-4 rotations of the crank before I had oil pumping nicely and light to go off.

Ya there is no problem between the pump and the pan, the drill did not have any load on it at all, and there was no sign of oil flow anywhere in the head atleast. And it would come from the HLA's over the camfollowers, we do not have rockers.

Well Over the weekend, John worked some magic and got my car back together and running better then ever.

The Funniest, and weirdest thing however was that for no reason what so ever the oil pump started working just fine. It was as if nothing ever happened.

All he did was pull off the oil feed line to the turbo from the oil filter houseing.

Crank over the oil pump with my impact gun, and Oil started flying out, which proved that the oil pump was working and at least oiling the block.

So we moved onto the head. - Pulled the Valve cover off Cranked over the oil pump with the impact gun.

And Oil started spraying out of the head. As if nothing was wrong.

So he put everything back together and we fired it up, oil light went off right away, and the oil pressure came up.

One things I've noticed now is that when I first start the car the oil pressure builds up slower then usual. But when it builds up it has a little more oil pressure then usual.

Since the weather was so nice yesterday I spent a good part of the day driving around. And she's back up and running like a champ.

As for the internal Dump - the Turbo is spooling a lot faster now then it did with it to atmosphere. Not sure why but the power comes on a lot quicker.

And although we didn't finish welding the dump tube all the way around 1 of the flanges the sound is still much much much much, nicer then the external dump, and so pieceful.

As for lbs/min - I haven't turned the boost back up to 22psi yet. But I'm sitting at about 20psi and I'm seeing 48lbs/min.

turbo still acts the same holds 20psi and then creeps at 7200 up to 25psi by the time I hit 8,000rpms.

Just wanted to share this weird experience. Not sure why the oil pump started working, etc. maybe it's just John's Pressence that scared it into working. Since John's the only person I have really let work on my car in a very long time.

Or maybe it needed some care from my trailer!?

DSMPARTSGURU · 08-16-2004

just a thought? maybe the bypass spring stuck or cot caught up? then weh nyou removed stuff / or the e ride jared it loose?

chris

Enes · 08-16-2004

e-ride fixes things.. hurry up and schedule yours!!!

SlowWhite · 08-16-2004

Well what ever it was. I glad things turned out ok. I was expeciting my motor to be shot, with the metal in the oil pan.

And I was thinking I wouldn't have my car back for another year. :headache:

But I'll say this I'm going to start to be much gentler on my car. I haven't launched it yet with the new set up.

And I haven't NLTS yet. I've been doing things gradual. 1 gear pulls, easy shifts, etc.

Another thing I forgot to mention is I put in a 170 degree thermostat and so far it's looking like it solved my temp issues.

At the high points my temps only reach 206.

Most of the time they sit right at about 196.

Used to be even if I was just cruising into work my temps would reach 216-220.

A//// Guy · 08-16-2004

Its cold outside thats the only reason your temps arent up there yet.

SlowWhite · 08-16-2004

outside temps actually have nothing to do with it.

My car always runs hot. Even in winter. (yes I take it out if the roads are clear/clean)

I know they'll go up a little but for normal cruising temps - being

185-196 (that's awesome)
WOT Temps only reaching 206 after back to back pulls is also awesome.

For my car that is.... Hopefully temps will get back up into the 80 sometimes soon where I can do comparisons.
