OK, here it is I just bought a 98 F150 4X4 4.6L V8 with 197,000 miles. There is a loud ticking comming from the passenger side of the engine its loud it stays loud going slow, fast, stopped any ideas. Also when I first crank it, it put out a tramendious amount of blue smoke. The engine also wants to die when I put it into drive and reverse. It runs strong there is only a little hesitation when I first accelerate, but it will get up and go quickley. Can any one help me. I can change parts my self but I dont have the time to fool with it. Me personally I think its lifters sticking or so I hope, and as for the blue smoke I know its from oil getting into the cylinder should I just do a complete gasket change or what. Please someone help ME. THNX

 

It sounds something like a bad valve or a valve that isn't seating well or something along that line. If it is a valve that isn't seating well, you can try running Sea Foam in you gas ans see if it burns away deposits that may be causing a bad seal for the valve. It is a cheap way to start.

Can you tell if the sound is coming from the top half or bottom half of the engine?

 

The sound is comming from the top half, and I have never heard of Sea Foam were can I get some.

 

Wal Mart or any parts store. It'll be in the auto parts section of Wal Mart. It's white can with res writing.

If the sound is in the top half, there is a good chance it's a valve issue of some sort.

 

Thanks I will get some in the morning. Thanks again

 

Is this seafoam stuff kinda like marvel mystery oil

 

I don't know that. It is designed to be run in the oil, gas, transfer case, differential, vacuum lines, etc. It goes through and gives a good cleaning. When run in the gas, it will clean the tank all the way through to the valves.

It may or may not work for you, but it is a very in expensive and effortless fix compared to taking the head off and re-seating the valves.

 

seafoam is good stuff i would put some in the tank and some into the vacume hose to,

 

Thanks.

 

I am shocked. I used some seafoam on my engine, and the results are amazing. The ticking is gone. I noticed I have more power. I will swear by this product on any day. Thanks to all who recommended it.
