Something is wrong with my car(had a loud backfire then blower oil under hood)

[Mr. Unknown]

Driving on Iriving from a stop light I reved it up to about 3K and dumped the clutch. Ran out first then hit 2nd. As soon as I hit 2nd gear the car backfired and lost all power then shut off. I pulled over to the side of the road. let it sit for a minute. Had trouble starting. Idled ruff. Finally the car starts and idles smooth.

A little ways down the road in 2nd gear about 4K i punch it. Everything seems good. Get home. Looks like there is tree sap on the windshield, go to clean it off. Pop the hood just to make sure everything is ok. There is blower oil all right by the hood latch. A LOT of it and its on the bottom of the hood. The Blower Oil filler/dip stick doesnt have a drop around it. Clean off the oil. As I look down to where some of the oil dripped. I see in the back of the radiator fan a silver screw wedged in I can't get out.


Anyone have any ideas?


This is where the oil was when I popped the hood

hmmmmmmm

I think something must've popped off the blower, does that screw look like it belongs on your blower?

 

[ITLLOWNU]

are you running a KB or whipple?


the KBs will spit oil out of the snout of the blower if they are slightly overfilled when spun up to high rpm. ive only seen i happen on brand new blowers and most of the time they were on the dyno being tuned and they would smoke from the oil spitting out onto the belt. but ive never seen that much oil ..

i would also check all the vacume lines on the back of the blower. if they are not ziptied ,they can blow off at high boost and cause the car to fall on its face and run really stupid before it just dies.

had that happen to me once on a 2nd gear pull and i thought i blew the motor...it took me forever to find the little line that had popped off

If memory serves Chris is running the KB 2.6

Hmm. No I checked the blower snout and didn't see anything. I skimmed over the vacum lines and everything seemed ok. Of course I dont know exactly where everything goes I'll have to take a closer look. My blower has about 1K on it.


Cliff was telling me to zip tie the lines last fall. I should have done that.

added a pic of the screw in the op

from the location of the oil im pretty sure it came from the snout

ive seen it happen about 7 times and almost all had no evidence of the leak after it burnt off from the belt.

but like i said we never saw anything close to the amount of oil in ur pics

and that screw looks to be rather large

So what should I do. Just refil the blower and everything will be ok? WHy did it do that?


Is it coming from this hole

 

[ITLLOWNU]

yes , the hole is for venting purposes it allows hot gasses to escape from the casing and will blow oil from time to time especially during WOT.

with the newly found rake on your car the oil level in the blower could be more towards the front causing it to spin up into the vent hole and thus blowing out especially if it was just slightly overfilled

i would just check the oil level very carefully and see how low it is, it might have just leveled itself off by blowing out

as far as the backfire goes it could have been a number of things but my guess is on a vacume line

can you tell what the screw looks like . it could tell us where it came from

Ahh thanks so much. the oil level looked fine. I will try and take a picture of it later tonight.


There is a picture in the OP of where the screw is.

 

[Bigturbonotch]

bolt can be from the crank pulley or another pulley maybe just check around the front of the motor chris.

 

[Flatliner]

That bolt looks pretty long and clean... check the idler bracket next to the supercharger pulley, there should be one on the top that holds it down.

If you can't find where it goes, could it be one that was loose just laying in the engine compartment that finally came out and hit the belt and was fired like a bullet?

 

[Mr. Unknown]

gonna check the bolt now.... brb

 

[Flatliner]

That bolt just looks way to clean, no oil grime, etc, makes me wonder if it was just hidden somewhere away from all the elements... weird.

 

[Mr. Unknown]

got the rad bolt out

 

[ITLLOWNU]

are you sure the screw hasnt been there a while and you just happend to find it then.

sux cause every bolt on these cars look like that almost:alcoholic

looks like a 10mm bolt thats used on the coil covers

 

[Bigturbonotch]

i second the coil covers now that you mention it,,,,,

chris did have those off

 

[Flatliner]

+3 on the coil covers... going to look at mine, I was thinking idler bracket.

 

[FR 500 HAND BUILT]

Hey Chris I know me and you bump heads here and there but check the 2 lines going into the front of the intercooler. There are 2 bolts holding it in place maybe it was one of those that came out.
