Ok,
My car has a wierd smell like oil mixed with gas, when I shift in high RPM's.
also When I rev hard black smut comes out my exhaust.

I saw an old friend yesterday and he was saying I was probably running "rich"?

Oil mixes with gas causing me to run rich
wich is caused by bad rings?

I was told I should get a compression test done.

my question is, does all this info seem about right?
and how can I do a compression test? is it something I can do?
or do I need to take it somewhere?


Thanx guys

 

check the rings. u can go to almost any mechanical shop and get a compression test. the oil wont make u run rich it will just cause ur car to smoke.

 

that's what I forgot, car does tend to smoke when I shift at high RPM's also. don't know the color cause i never pay attention when I'm driving :\

 

smoke can be caused by coolant and oil or gas and oil. how heavy is it smoking?

 

not bad at all. like a quick lil shot of smoke when i shift at like 7-8k RPMS but that's it.

also, how hard is it gona be to change rings if i've never taken apart my engine before?

 

if its just a little puff I would'nt worry about it...better rich than to lean you could lower the fuel pressure a few punds if you have an adjustable fpr but if not i would'nt worry about a little puff at high rpms...

 

so running a little rich meaning bad rings isn't a bad thing?
I thought if rings were bad i needed to fix asap?

 

If you had bad rings you would have a blueish smoke coming out your exhaust. This would happen most of the time. It doesnt sound like that is your problem. If you go to Autozone they will lend you a compression tester for free. All you have to do is put a deposit down untill you return it. they now do that with all automotive tools. If you have good compression and want to fix the problem a dyno with A/F readings is your best bet.

 

if its a little puff of BLACK smoke when you shift it is most defenetly not rings...you are running a little rich and thats fine.

 

Yes of course all mighty confusious
