******* english would help, Now past that.. It sounds like you have multiple issues..

Have no idea what your mechanical skill level is.. But i would check your oil pressure with a mechanical gauge, because I believe you mentioned your oil pressure was around 20psi?

If that is true, you have an issue that isnt electrically related.

 

Everyone else can understand it just fine. Thanks for your 2 cents. I am sure it will help him figure the problem out.

 

Did you check all your grounds?

 

I know it would be a hassle to get it back to xxx, but if they screwed something up then they should fix it. Granted, most shops in their right mind are not going to put a warranty on anything that has knowingly been down the drag strip. Atleast call them up and tell them what is going on.

 

well this is not what you gonna want to hear but the cherping is more than likely a rod bearing mine was doing the verry same thing

 

There might be codes that tell you something with a scan tool?

The only time I have lost oil pressure is when my car started overheating from the thermostat. It would spike and jump around a lot.

Wish I could help, call the shop and talk to them about it I guess.

 

No not really... And I added my two cents in helping the OP, not just pointing out the Sp errors.

But thanks for your informative Post.. I am sure it helped the OP too.

 

Well If i read correctly the OP said he tried or did drive his car home on 20 psi of oil pressure..

I would be inclined to believe its internal also.

 

After you saw my post you went back and edited it. I quoted the whole thing originally. He doesnt need people telling him to learn English.

 

id check the plugs as well my car acted this way and did the same thing when i fouled 4 plugs out

 

I'm thinking rod bearing as well...

 

I have no idea what your talking about... Its dropped, Move on.

 

Why would an internal component cause his dash to go stop operation? He said it still drove fine during the first pass. I think also that there is a bad ground some where. You said you had a pinched ground wire did you clip it and repair it or just free it? I had a ground wire loose when first started my 6 liter for the first time and my dash fluttered and stopped working, and the truck ran like **** till I got it found and tight. Check and make sure all grounds are tight and in good working order. I think the sound is too sporadic to be a rod. It also doesn't seem to coincide with RPM like a rod would all the bad rod bearings I've ever heard get alot louder and deeper sounding then that with rpm increase. JMO...

 

I Redone the wire. its no longer a player. And no my mecanical knowledge is not the greatest ,but thats why im on ls1 tech trying to learn something new. Im going to take it around the block with a camera . the car has not moved since the wrecker dropped it off

 

Does the dash work now, but the motor just runs like ****?

 

Where Is the Oil pressure at?

 

But is that being read off the dash or not? If the dash is on the glitch it might not be reading correctly...

 

i didnt get a chace to drive it today but the oil pressure at idel is normal sitting at 40. the chirp/squeal noise is gone my bad it was a pully. I have a buddy coming down from VA this weekend to help me out. he also thinks is a bad ground so we are going to track it down. thanks for everones help i really needed this to calm my nerves and to keep from going ape **** over my car!

 

Chase your grounding issue. Thats all it sounds like right now.

 

Kind of sounds like this diesel sound could possibly be a vacuum leak from somewhere around your intake. Maybe check the back where the map sensor and vacuum lines come from.

Good luck hope you get it fixed.
