Dollar bill to the tail pipe.. WTF?

[Hickfied]

I was talking to my friends mother today and it turns out she was a mechanic for 20 years. She told me that if I held a dollar bill to the tail pipe and it was blown away, I had a healthy engine, and if it was sucking in, I had a poor running engine....

WTF?!?!


Now i've heard of sticking one on the oil fill hole to check for blowby, but this one just seems to far fetched for me to believe.

Well, I'd imagine if your exhaust system was sucking air in backwards, you'd have some kinda problem there

LMFAO

 

[Mr. Rustypwnz]

you guys have never heard of this before? its about low compression or valves I forget, but yes it works!!!

 

[Ozz]

Nope, never heard of it. Not doubting, just never heard of it.

 

[FrankenStang]

I was merely LMAOing at mansonozz for some reason.

Makes sense, if your EXHAUST was not exhausting it you have problems.

There is some truth in this tale, as it dates back to carb only cars with no computer. If the dollar bill flutters and never stops fluttering , all cylinders on that exhaust pipe are firing. If it drops, then one or more cylinders are missing.

A cylinder balance test using the computer's built in diagnostics is a much better way to test a 5.0 Mustang.

So why does it have to be a dollar bill? What's the matter with a $10, or a $20?

 

[Hickfied]

One dollar bill, 10 dollar bill, 20 dollar bill, never said a one dollar bill

 

[Gearbanger 101]

One dollar bill, 10 dollar bill, 20 dollar bill, never said a one dollar bill

She told me that if I held a dollar bill to the tail pipe....

You sure did. A dollar bill = 1

 

[Hickfied]

A dollar bill yea, i figured one would work as good as two of em?

 

[Gearbanger 101]

Way to suck teh funnay out of it.

 

[Hickfied]

No problem

 

[lx93notch]

yea its a cheap alternative for trying to find a compression problem or burned valves

Reminds me of that episode of South Park where cartman was shoving food up his butt and pooping out his mouth.

 

[Mustang5L5]

One dollar bill, 10 dollar bill, 20 dollar bill, never said a one dollar bill

I personally would just use a peice of paper. But if all you ballers want to stick your $100 bills up your tailpipes go for it.

It's Mega-Maid sir! She's gone from suck to blow!
