armin922 Posted April 11, 2005 Report Share Posted April 11, 2005 my stang pops for some reason. It warms up and the exhaust pops, doesnt backfire but pops. I also checked the oil dipstick and it smelled like gas, so im thinking somehow there is gas in the oil. Would that cause it to pop? I have an 88 stang 5.0L with about 180k. How would gas get into the oil? Also, if the timing isnt right would it cause it to pop as well? Quote Link to comment Share on other sites More sharing options...
nicktcfcsb Posted April 11, 2005 Report Share Posted April 11, 2005 your timing would have to be way off like if you timed it off the #5 cyl and not the #1 Quote Link to comment Share on other sites More sharing options...
stolen 5.0 Posted April 11, 2005 Report Share Posted April 11, 2005 define "popping" sound better, and if u think the timing is off, get a light on it. fuel is oil, spraying fuel past the rings and it's getting into the oil maybe Quote Link to comment Share on other sites More sharing options...
armin922 Posted April 11, 2005 Author Report Share Posted April 11, 2005 the car has about 180k and i dont think the fuel rail and the injectors have been changed or cleaned. I also think maybe an O-ring for the injectors is leaking. After about 10 mins i noticed some gas ( a little) under the upper intake so i suspect one of the injectors/fuel rail having a leak and maybe thats why the oil has gas in it? The popping sounds like a baloon but not as loud and not as high pitched. We did try to re time it with a light and got thrown off because we decided to check the oil and it smelled like gas. So we werent sure whats wrong with it. Im gonna maybe change the oil and see what happens. Maybe the whole distributor was maybe replaced and maybe not correctly put in? IDK.....Bottom line, the stang is sick and i want to get it running before the summer..... THANKS GUYS Quote Link to comment Share on other sites More sharing options...
armin922 Posted April 13, 2005 Author Report Share Posted April 13, 2005 would anyone happen to know whats wrong? Quote Link to comment Share on other sites More sharing options...
Buckeye1647545503 Posted April 13, 2005 Report Share Posted April 13, 2005 Do yourself a favor and check ALL the basics before letting use E-guess. Check the fuel pressure, timeing, compression, and inspect and fix ALL leaks fix the leaks now. They need done any way and it will make working on it better. If it is just a poping when you rev it and let off it is most likely an exhaust leak sucking air. Quote Link to comment Share on other sites More sharing options...
smokin5s Posted April 15, 2005 Report Share Posted April 15, 2005 Do you have cats on your car? If not, I've seen cars with no cats do this. Quote Link to comment Share on other sites More sharing options...

Dave1647545494 Posted April 15, 2005 Report Share Posted April 15, 2005 symptoms- oil smells like fuel exhuast is popping.... you have a bad injector, fpr, or a bad mass air meter. you not only are leaking fuel past the rings into the oil but some of the excess fuel is running into the exhuast and igniting... if you can put it on a scanner and look at your maf values if they are in range its a fuel system problem. you can chaeck the reg with a pressure tester and you can check for open or shorted injectors with a multi-meter. hope this helps Quote Link to comment Share on other sites More sharing options...
