1G Oil squirters and spun rod bearing.

[eldiabloz13]

Now my tsi spun a rod bearing. But he said it was from trying to burn out with AWD. Just thinking about it now i remember my engine not having oil squirters. Could this have caused the spun bearing. Also how needed are they.

You're going to have to tell us a little more information.


1) Did you replace your shortblock with a non-turbo one that didn't have oil squirters from the factory?

2) Did you (or someone else) remove the oil squirters, but block off the hole where the squirters were?

3) Did you (or someone else) remove the oil squirters from a turbo engine and leave them open?


The first two are perfectly safe and, if anything, might give you *less* of a chance of spinning a rod bearing under heavy load. The third option is definitely very bad for your oiling system, and could very well have caused a spun rod bearing.

Doing an AWD burnout on an otherwise healthy engine would not cause you to spin a rod bearing, assuming your engine had proper oil pressure (a good working oil pump and enough oil in the sump.)

Ok it goes like this. Im the third owner. The first owner built this car extremly. Then 2nd owner baught it to beat on it. He did awd burn outs on dry nights and all that stuff. Im the third owner and when i removed the engine to have it rebuilt i dont remember oil squiters.

The type of bearing that went bad was a KING bearing. Thats not factory so i know the engine was built by the first owner.

How many miles were put on the engine before it spun the bearing? Who assembled it?

 

[eldiabloz13]

There was 178K on the engine before it did it. I dont know who assembled it. I just know the previous owner. Its could have been done from a half brained monkey at NASA and i wouldent know.

1) dont blame oil squirters.

2) oil squirters are for cooling down pistons.

3) most likely you had low oil pressure or lack of.

I personally dont use oil squirters, and i havent had any problems. Some people actually remove them from turbo engines. I bought a n/a block, and there it is, working the same as a turbo engine.

Sorry to hear that happened to you. But you better start off rebuilding. Its way better, and it gives you the piece of mind you need. Good luck.

Holy crap. You finally beat it to death. The lack of squirters had nothing to do with it.

Dont blame the oil squirters? Im not posting blame on anything. I just wanted to know because my engine is in the process of being rebuilt as i type this and wanted to make sure they werent needed. I figured high mileage was the cause, but it was rebuilt at one time before. So even at 178k it shouldent have done that i figured from the use of new king bearings. I just wanted to know if there needed so i could put them in my block if i didnt have them.

The squirters are for cooling the piston crowns. They don't effect the rod bearings. If anything, you might have very slightly more oil supply to the rods in not having the squirters. Most engines have squirters, but they're usually a pinhole in the rod and meant to get oil onto the cylinder walls for the rings and skirts rather than for piston cooling.
