I too have read about a product called "Auto-Rx" and "Seafoam". I have likewise read that seafoam has been around since WW-II and has been used to clean out Jeeps that were driven in harsh conditions. My feeling is that something has been around since WW-II still wouldn't be on the market if it wasn't working, although I myself have never tried it.
Here's my issue that I'm trying to resolve and I hope I can get good input on this. I bought a used 1993 Maxima that I feel was not well maintained by previous owner(s). After doing tuneup, changing PCV valve as well and so forth, the issue was not really resolved and would be worse when the motor was cold. It would get better as the car was driven. My feeling on this, is that the headgasket material would warm up further and seal better, under heat (from driving). In addition, I took the car to a shop and it was diagnosed with two bad injectors. I'm having work done this week to resolve that,replace all 6, and in addition, they'll use carb-cleaner to clean out my EGR valve.
I don't yet know what the car will run like with that work done, but I was hoping to clean out sludge from the motor to further extend its useful lifespan. I think part of the problem was the gas filter wasn't changed often enough, by the previous owner, no spark plug changes, wheel alignment was way off, tires were nearly bald, in other words, plenty of indication of a car that was pretty neglected. So, I already put so much money into this car, I can't do anything except hope it lasts another 2 years. So I'm hoping to clean out sludge and varnish in an effort to make the best of the situation.
Any advice really appreciated.
