I have an older truck with about 200K miles on it and every so often I have a lifter making noise. It clears up once the engine gets warm. My NAPA dealer told me to add a pint of seafoam into my oil.

Any thoughts,
Thanks R.Lay

 

My 67 Imperial (440) had a sticky lifter, same thing....quieted down when warm. Did the full seafoam treatment through the vacuum line on the brake booster. Not my imagination but the lifter noise is gone, car starts better, idles smoother and throttle response improved. I don't think I would use it on my newer vehicles but it sure seems to be an 8 dollar mechanic in a can on the old ones.

 

When you change oil, just switch out a qt of ATF for what ever oil you put in, does the same thing and cheap, Like for a 302 put in 5 qts motor oil and 1 qt of ATF.

 

I honestly haven't heard of the add a qt. of ATF, however, i can say that Seafoam really works. If you do go ahead and buy it to add to your oil, do an oil change within 50 miles if not before that so the loosened sludge particles can get out of the engine.

 

Yeah Def do an oil change not too long after using seafoam in teh crankcase, but I have used it in the gas tank, crank case and in the booster line. Works like a charm. Local auto store puts it down to $6 every now and then so I buy a few cans then.

 

It should be ok on newer cars, I've used Seafoam through the brake booster vacuum line and in the fuel tank on my 1997 Honda Del Sol and on my Sisters 2002 Toyota Camry and we had improvement in both vehicles. One of my neighbors have used it on his 2009 F250 Diesel.

I've also used in on my 1991 F350 7.3IDI DRW and my Dad's 1989 Chevy 3500 350ci.

 

So, it sounds like you have used it in a few nehicles as far as the intake systems go. I was wounding about the issue of adding it into my oil?

Thanks for the reply.

 

No harm in using it in your oil, but I'd reccomend doing it just before an oil change, maybe 500 miles. It'll clean your motor and will prolly loosen up chunks of buildup, dont want those newly freed chunks floating through your oil passages.

 

yep just like everybody else said, add some into the oil but dont leave it like that too long. also, try to drain the oil while the motor is still warm to prevent all the debris from settling at the bottom of your oil pan and not coming out with the old oil.
