Ticking sound???

I have a ticking sound coming right from the valve cover gasket. It only sounds for about 20 seconds iv hade it for a while but sense I fixed my ac compressor it became a lot louder. When I rev the engine its really loud it makes a ticking and rattling sound. So in guessing I have a blown valve or sticky valve some kinda valve problem can some one help me out is it a serious oroblem and could this cause a cylinder to misfire

Re: Ticking sound???

Could be a valve or a lifter. Other issues are possible although those are the most common.

Re: Ticking sound???

depending on if its an OHV motor vs the newer overhead cam motors it might be normal valve train noise or injectors

Re: Ticking sound???

Possibly dropped/bent/damaged/corroded valve.

Perform regular diagnostics , swap plugs, injectors, and coilis to see if the misfire can be eliminated. Also perform Compression test and leak down test. Sounds like you may have dropped a valve or have something else internal going on.

K....did you change oil brands or weight. Going up one viscosity grade may help. Or it could be sludged up and a seafoam treatment might be in order

Seafoam is a petroleum based product that can be used in the fuel/crankcase and into a vacuum line to soak the valves/pistons. It dissolves carbon and sludge effectively without harming rubber/ gaskets. Can be found at most auto parts stores. Follow the directions. I don't even buy the small cans anymore. I but it by the gallon. It works great. What year is your mustang. There are YouTube videos that detail the application and which vacuum line to dump it in. I seafoam my car every 3rd oil change. If you use synthetic oil you really won't need to do the crankcase but follow the directions and you are good to go. I did my mustang when I bought it at 70k miles and the difference was remarkable. Made a believer out of me.

K well that's perfect so unless you upgrade to an 0w40 for 1 oci just to maybe see. And I have found a product that seem to live up to it's claims. It's called lubro-moly. It's a friction reducer and works remarkably well. I have only been able to find it at napa.

Re: Ticking sound???

I think you may have a reasonably good chance at improving things greatly by stopping by the autoparts store and get the Seafoam, Synthetic 10W oil this time, and add that Lubro-Moly to the crank case. Motorcraft copper plugs and don't forget to put a full can of Seafoam in to the gas tank.
I think your odds are good.

Seafoam cleans...lubro-moly plates the metal. Do not mix. Seafoam first in cheap oil and go about 1000-1500 miles. Drain it. Put cheap oil in again just to wash out all the seafoam and whatever crud the seafoam loosened up. Then moly. I went 5 tanks being very consistent with my test truck and the moly got me a about 3 mpg better mileage. The moly was the only change. Same oil and driving habits. Made me a believer out of me

If your gonna go synthetic find a 0w30 or 0w40. They are true synthetics because it's impossible for them to cheat with those types. They can't get a dino oil to get the 0w

What weight and brand of oil did you put in when you changed it. Or are you still on the clean cycle. When you change it out I highly suggest lubro-moly. You can find it at napa. The ticking will go away after about 300 miles

Please give it about 100 miles, enough to burn the full can in the gas tank. Check back.
Is it running better, same, different now?

After you put the seafoam in how long did you let it sit before starting it up and blowing out the junk?

As soon as the white smoke started coming out the tailpipe I shut er down and let it soak for 20 mins. If it's never been done before do a 30 minute soak then take it out for a high revving drive for about half an hour to get everything cleaned out. Depending on mileage you may want to do it twice. You will see a difference in exhaust smoke. The first time you do it it will smoke out the whole neibourhood. The second time it will be much less if it's clean. I do a treatment every 3rd oil change. Car and truck run like new. Seafoam also has a spray can so you can fog the intake instead of using a vacuum line. The instructions are pretty detailed but leave it sit for a minimum of 20 minutes to dissolve all the carbon. After you do it report back on your findings so other less experienced members can get real world info

K...try to time it so that you have no more than 1500 miles til your next oil change so it can clean the crankcase. If it's really dirty it will loosen up alot of crud and clog the oil filter. If I can make a suggestion. Add it to crankcase in existing oil. Drive 1500 miles. Change oil with the cheapest oil you can find to rince out the insides for another 1500 miles. Then change again and use a quality synthetic and filter. Synthetic oil has great speaking ability so once you do a clean and rince cycle you really shouldn't have to do crankcase again,just intake and gas
