Do you have 911 on speed dial?

You need fingers to speed dial

Does your phone respond to voice commands?

Does Bonnie recognize voice commands?

Son of a %^&*# = Bonnie bring the bandages.

Mother *&^%$# = Bonnie dial 911

&*^$ Me = Bonnie I need a beer and a hug.

From what I can see by the pictures, the pump is junk, but yes, what went through the pump to trash it?

I assumed it came FROM the pump. I did not find any in the oil pan. But I have not been able to look in the pan real good. Just the oil that I drained.

I don't know. But the pump still looks good enough to run yes?

just a few reasons pq needs to live in Tx


1 pleanty of friends to help tear into your car and fix it

2 you think our alcohol at parkinglot parties is good wait until you expierence working on a car.

3 always a shop with in 25 miles that works on these dam things if you mess up something.

4 tow truck guys are waiting in parkinglots all over 24/7 ready to tow you to a shop if you need help

5 when you have suspension problems pete is more likely to come and help you personally in Texas.

6 Tex Mex lol always seems to brighten your spirit.

7 always a gtg or Camaro gathering with friends.

8 To hell with working on that car no matter where you live in Tx you would be just a few from either Bourbon Street LA or 6th street Austin lol

9 Tx mile to a hand full of 1/8 and 1/4 mile tracks all over the place.

10 much easier to talk $#IT to half of the people on here in person than do it on C5


besure and make a video of this tear down I enjoy listening to you cuss at yourself

Low oil pressure is usually a bad pump or bad bearings. You have debris in the pump from an unknown source.

Pull the pan and see what is in it.

or

Install a new pump and see if the pressure comes back. If the new pump restores pressure do a quick oil and filter change and hope for the best.

or

Tear it down and rebuild it now.

Opinions????

Pulling the pan is almost as easy yanking the engine as it is cutting the cross member and removing the steering rod and what a PITA.

I thought about installing a new pump to see but what a PITA.

Tearing it down and rebuilding it now, what a PITA.





Ok, my thoughts are that I feel confident this pump is working fine. And since this oil pan is so hard to get out and it's safer being absolutely sure by inspecting the internals that I'd pull it to look at the pan AND the bearings. I suppose putting a new pump on and putting it back together could be a test, I just didn't want to waste any time. I could buy one of those probes with the video screen but not sure how accurate the info would be. I might miss material and not know.

I welcome thoughts of course.

Disclaimer: I am not an engine expert.

My best guess is you're losing pressure at the cam bearings. Maybe we can get an engine expert to weigh in.

Just my opinion here but with that many miles I would think the engine could use a rebuild anyway! Especially with the Maggy on it and the way you downshift it has had a hard life! If you decide to pull the engine I would stroke it and use some forged internals, or replace the whole engine with an LSA crate or LS7 crate engine. Then sell the LS3 for the block and sell the Maggy to recoupe some cost!

Edit: sell the L99 not LS3. Forgot you have an auto

I can't afford an LS7. Even selling my Maggie. It'll depend on where my problem is that I try and figure out where I go from here.

A whole new engine is enticing but not practical for me right now.

Tear it down and have a machine shop check the crank, block and heads and machine as required. If my guess is right, you'll need a new cam. Most everything else should be good. Replace the rings, bearings and gaskets along with freshened heads and you are good for another 86K.

Another option is pull the engine to replace the cam and bearings. While it is open replace the main and connecting rod bearings. Install a new oil pump and you should be reliable for a fair number of miles.

Can you do a compression test as she sits?
Cylinder leak down?

Again, I am guessing, but I think the debris will be from the cam and cam bearings. I think you can check them with the engine still in the car and a scope. A close inspection of the cam will probably tell the story.

I thought about a compression and leakdown. I just didn't figure it would be related to the valves and rings yet considering the loss of oil pressure. Not sure it would be smart to do with the oil and water pumps off. hahaha

Compression and leak down check are not related to the low oil pressure. If you find a low cylinder relative to the others it raises the possibility the debris in the oil pump or pan may have traveled and done other damage.

Again, I am not an engine expert, but the minimal cranking required to do a compression test without any plugs in the car shouldn't do any damage.

True. I only ever turned it over like 3 or 4 times to get my pressure for the tests.

I always hated those tests because if you found what you were looking for it meant bad news.

Nope. You're the Jason. haha

I'm thinking the pump just chewed it's self up. Started to wear and then wore to a bad level and just started to do that. I'd bet money I take it apart and find nothing. That metal in the filter definitely came from the pump because I bought a new pump and the gears mesh perfectly. So there was a lot of metal missing from the pump gear lobes.

Spent Monday looking for a reason not to pull the cam and put the engine back together. Had to bowl yesterday evening. Team is in first place so they want me there. (though I'm not sure why, my lower ab/groin pull is not healing)

Anyway. I have a busy week at work and a tournament to bowl this weekend. UGH................
