Hello, back again needing advice for my 06 toyota corolla. Its a standard transmission with 97,000. I also recently cleaned the throttle body and replaced the valve cover gasket to help stop a oil leak and to allow it to run a bit better...but it runs rough with a LT fuel trim of 7.0% and a short term fuel trim of -1.6%...and this is after I ran some royal purple fuel injector cleaner through it...
I have noticed last week my little daily driver was down to 25% of a tank when I only filled it up a week prior. Usually I get two weeks of driving before having to refill. I also noticed a puddle of gas tends to accumulate when I have driven for a while. I tried to catch where the drips were coming from with cardboard, but alas, nothing... I am thinking its dumping extra fuel when the system has pressure in it and when I am driving along...I restarted a trip odometer to gauge how the MPG is actually, but I am shocked and worried since I saw a recent trail of gas from my car before all this happened.
The next idea I had was to head to my oil change place and ask to check for leaks along the fuel lines, starting from where I fill up all the way through to the engine. I am going back there on Friday to see if they can do a follow up to see any more leaky spots that are not just condensation since its been raining consistently for a few days in a row.
I am at a loss from where this leak could be. Could it be from a failing automatic chain tensioner? Could it be from a leaky oil pan gasket? Is my head gasket gonna blow soon? If anyone has a list of gaskets that could be failing and that I should look directly at, or diagrams/resources that could help me learn where to look next, I would grateful.
Could it be from a failing automatic chain tensioner?
I'm not sure what a tensioner would have to do with anything.
Could it be from a leaky oil pan gasket?
well then you'd have an oil leak. You said you had a fuel leak. You can tell the difference right?
Is my head gasket gonna blow soon?
why would a head gasket blow?
replaced the valve cover gasket
maybe you disturbed the fuel rail or fuel lines so I'd look around there. Gravity will make everything drip down eventually. Try a leak detection dye kit.
I'm afraid I'm having trouble following that narrative. What makes you think the head gasket is going to blow? Timing chain tensioner or oil pan gasket causing fuel leaks? Huh?? Very confusing.
Be that as it may, if that car is leaking gasoline you'd better make fixing the problem a top priority unless you want to experience an impromptu roadside barbeque. If your "oil change place" is a quick-lube joint you'd better stay away from them and get that car to a real mechanic ASAP if you cannot work on it yourself. With a fuel leak it would be safest to have it towed.
I agree, its better to find a better shop. I'll ask some of my friends for their favorite shops...sorry for the confusing story, I was asking about the timing chain and head gasket because I don't know what would be the cause. But the dye kit is a fantastic idea. I'll search for a kit that I can buy amd how to use it. Thank you for your reies everyone.
