I added seafoam after an oil change don't know why. Didn't notice any changes in my car except it being difficult to start the first time and I think performance was actually better then it is now. I became concerned when I read various threads saying to add seafoam before an oil change which the bottle does not say this. I drove 1,428 miles until I changed my oil again to remove the seafoam at 49,800. Now I have 50,986 miles. Maybe I didn't notice it before but now I hear a strange metal tapping sound by the wheel wells long with my lifters sounding louder then usual and other strange noises. A couple people on yahoo said I might have clogged a lifter with sludge. I'm concerned that with exceeding my oil level I may have caused damage to something to get that faint metal tapping sound. I noticed that my coolant recovery tank was close to empty when it kept making a gurgling sound. The engine was at full operating temperature. I checked it again this morning after it has been sitting all night and the recovery tank still has the same amount as yesterday and the radiator looks empty but my car never over heats. Dex-cool coolant is suppose to be good for 5 yrs or 100k miles. The cars only 4 yrs old. Should I be concerned with flushing the engine coolant and changing my spark plugs too. Someone told me not to use dex cool because its bad and that I may be letting air into my cooling system or worse a blown head gasket, they told my to switch to green stuff but what is that? I do a lot of driving and tend to be hard on my car as well. I am getting ready to go on a 6 hr road trip pretty soon is there anything I should check or have changed? I know I need a transmission flush, engine air filter, and supercharger oil change. I'm not due for another oil change until 52,800 and currently have 84% oil life remaining. Which brings me to another question, is it better to change full synthetic oil every 3,000 miles or go according to your oil life monitor?
You've got lots of questions,don't you?
You won't damage your engine's internals by overfilling the engine with oil [710 for you ingrates
].
You've probably removed the varnish that builds up on the parts and *may* have got some stuck in your lifter[s].
Don't sweat it.
Synth's are good at dissolving and suspending varnish and dirt that builds up in the oil.
Six hours on the highway will clear out any crud.
Your coolant should be flushed out and changed.
It's probably damaged by running too low-less of it doing more cooling.
When they flush it,have it checked for hydrocarbons.
Don't let them over pressure your system when they flush it.
You can blow seals,hoses,heater cores,etc.
It's a classic trick used by a lot of low life rad shops to generate business.
You can switch to peak Gold coolant.
The green stuff has Silicates in it that can chew up bearings in your bottom end,if it gets in there.
For the trans,drop the pan and do a filter,fluid change.
No real need for a flush.
They'll probably refill with Dexron VI.
Good stuff and better than Dexron IIIH.
The super charger oil is relatively easy.
There's a write up here:
viewtopic.php?f=13&t=9815&hilit=Changing+the+Supercharger+OilThe air filter is a no brainer.
I would clean the MAF and throttle body as well [if this hasn't been done in a while].
I would take it to the dealer and let them go at it,considering the amount of work you want done.
You may find their prices aren't bad either,considering the economy.
