And have you discovered the source of the problem?

 

NO not yet Fred. The only thing I did today was pull the fuel filter out. My good buddy gave me his exterior fuel pump with filter of his TPI motor that im going to install. So im going to put that in. Im going to drain the oil and check it out to make sure theres no issues there. I check it today and the oil is fresh as can be. I really think I put too much oil in. I dont have a real dip stick. I have a dip stick from autozone. Not an Lt1 stick. (YES I need to get one) So after I do all of this im going to try it. I for sure wanna look into getting a dyno tune for it.

I forgot to add when I pulled the oil stick out. The oil was rather High on the stick. And on my previous runs, my car has never splattered oil out like that. The only thing that it has consistantly done is the motor would quite after a run.

FRED. you had mention FROTH in the oil pan if there is too much oil. I looked up Froth and it said (Foam causing bubbles) When I pulled out my dipstick after my run that splatter oil all over the place. I SAW A FOAMIE SUBSTANCE ON THE STICK. That just verifies more of what you had stated.

P.S. Sorry for not putting all these comments in one post. I just remember things after I click the submit button hehe

When the oil is up closer to the crank, the crank whips it into a froth. That air ends up throughout the oil in the pan, and the oil pump is now sucking in air and oil.

 

So would that explian why oil shot out of my breather cap and completly got oil all over the motor? With this theory im wondering if this is the cuase of my car falling on its face and shutting off.
Thanks
Chris

 

OK. Update!!.
I did a oil change
Changed the fuel filter becuause I thought maybe the filter was clogged and it hasn't been changed before.
Checked all hoses.
NOW!!!! all of a sudden for the WILL not idle AT ALL. (FYI and it was idling just fine at the track) Now it will not idle. I took the car around the corner to test drive and as soon as I put the car into gear. It died on me. I get it started and again. It WILL not idle. Oh and by the way. Its throwing NO CODES no SES LIGHts what so ever. After everything that I have done. THe only thing that I think left is the FUEL PUMP. The fuel pump can not pump enough fuel into the motor.
So thats that.

(I'm Starting to HATE EFI cars)

Chris,
It sounds more like a vacum leak rather than a fuel problem - since it won't idle. Try CAREFULLY spraying some carb cleaner (throttle body cleaner should work as well) around the intake and see if it will keep ideling/idle picks up...
Call me tomorrow if you need help.

 

What oil pan? Hopefully it's not the stock one. If it is, does it have a windage tray? How many quarts of oil did you use to get the pressure back to your normal range?
It could be what was already suggested and you're over oiling the top end.
Get a fuel pressure gauge. However you need to replace the pump and injectors anyway for that application.

 

My stock pump could not keep over at over 4k rpms with ~460 at the flywheel.It was dropping fuel pressure down to the low 30s at WOT and had a dip on the dyno graph where the peak should be - almost like the last few hundred rpms of the graph were cut off and inverted. A racetronix kit and harness solved that problem, but then like you my car would not idle properly either. At higher rpms giving it gas it was fine though.

I have an interior electric fuel gauge though, and so I quickly noticed the quick bleed rate - which led me to find a leaking injector causing the horrible idle. Check your fuel pressure with the car off and see how fast it bleeds down after it primes.

 

Well I might have found the issue of the idling. I placed an old rubber hose from the TB and connected it to the bottom port of the purge canister. This was the only thing that I can think that I had done and sure enough. Based on some diagrams off shoebox's web site. That hose from the TB is suppose to connect to the top not the bottom. So I just pulled if off and placed the rubber cap that I had on the TB.

SS.RRR: Yes!!!! I do have a stock Oil pan. I banged it out when I clearanced it. As far as the windage tray. Its stock too. Could this be my problem?

I too believe that my fuel along with the vacumm leak is cuasing my issues. Although IM pretty sure I fixed the idle issue becuase I placed that cap back on the TB. But I think something else maybe going on with the engine. I checked my oil today and I didnt like what I saw or im not sure what I saw or what it could be. I saw some what looked to be dirt mixed in with the oil that I JUST REPLACED. I have no clue that is oil what it may intel. But Im getting really frustraded with this LT1. Thanks guys!!!

P.S. Im about 2 clicks Away from going with a BBC and skit caning the SBC.

 

I'm not going to positively say that is your splashing problem, but it has been documented how a h/v oil pump and stock oil pan can be a lethal combination. It is still possible you are over oiling the top end of your engine. Do a search under rskrause regarding h/v oil pumps and stock pans.
How many quarts did you use to bring the pressure back up? The stock pan is only designed to accommodate five quarts. I'm wondering if you're putting too much oil in causing the crank to agitate the oil.

 

I put in standard 5 quarts of oil. Now that I'm thinking about it. When I clearanced the pan. the crank is super close to the windage tray when it rotates. When I had to get the pressure up I put in a quart and half give or take.
Chris.
How do you explain the gray substance in my motor with the oil?

 

I have not the slightest idea what that could be. Are you talking about the froth? 1.5 more quarts of oil could definitely cause agitation. What I would suggest is ditching the stock pan for an aftermarket one or ditching the oil pump for a standard one as long as you stayed faithful with the standard bearing clearances which the book recommends.

 

Yeah your prolly right. If I have to pull that motor. I swear on the Fbody Gods. Im putting in a BIG BLOCK. My car is a race track car anyway. And I have no idea what that dirt like substance is becuase I had just done a oil change on it before it died on me around the corner.
BIG BLOCK IS sound good right now.
Im just tired of the SBC and the EFI.
