325e sounds like a diesel

I am looking for some advice/help for my car.

when the car starts and runs (not really) it sounds like a diesel engine. Not to mention there is absolutely NO power to move the car with.

I believe that this is due to water in the gas.

any help/tips would be greatly appreciated.

i dont know but this may be due to shitty injectors......because when injectors are old the can make that "tic tic tic tic tic" noise

BRAD 82 07-14-2008 11:25 PM

and i guess water going through them probably finished them off?

Thanks slimjim!

Anyone else have any ideas

Run a compression test

BRAD 82 07-14-2008 11:47 PM

how do i do that?

slimjim 07-15-2008 12:16 AM

if u are getting water in ur engine, when the car starts or struggles to, white smoke would come out of ur exhaust. u might even have cracked rings? its hard to say.

is there anything else u notice when u start or try starting the car, did anything prior to this problem happen like overheating?

no it isn't water IN the engine constantly. it game from gas purchased.

it was water in the gas that caused the issue. tank has been drained now.

get a compression tester, and google for instructions, or take it to charlie, shouldn't take longer than half an hr.

if it sounds like a loud lawnmower, or helicopter then its the bottom end bearings.

Had that sound on my old engine, tore it apart before putting in my new engine, all the crank bearings were scored.

Every engine gets some white smoke, and water for the first 5 to 10 mins. beyond that, does your coolant level get low? could be leaking coolant internally.

Later man.

My car does it too. It seems to be a normal ETA thing these days. It's the timing reference sensor, or the engine speed sensor one of the two on the bellhousing of the tranny.

Yeah, I had a vehicle that had that problem once, it only started sounding like a diesel engine though when the damage was bad enough (due to the lack of lubrication because of the dilution of the oil) that i needed an engine rebuild (new block)

engine ran fine before the issue of watered down gasoline.

will be getting a compression tester today and doing one tomorrow.

I hope its not too major of a problem. but i guess the compression test will tell me that! I am thinking it is a head gasket

slimjim 07-15-2008 08:59 PM

how do u know it was watered down gasoline?

BRAD 82 07-15-2008 09:39 PM

Well I never personnally saw it but the guy I bought the car off of said that was what happened. He also said it was drained.

That's what I have to go on. I am planning on running a compression test tomorrow to see what I get. Personnally I think it may be the cylinder head gasget. But we will see.

BRAD 82 07-17-2008 07:38 PM

Ok. Ran the compression test and got 120psi on cylinders 1,2,3,5 and got 100psi on cylinders 4 & 6.

All the spark plugs are worn and probably need changing but this still doesn't mean the engine would sound like a diesel. Would it?
