I personally do not like doing a engine flush as it can eventually plug up oil passages. Especially in a old engine. Why would the mechanic want to do this? Also if the engine has ben taken care of threw the years with changing the oil, there should be no need to do this.

hello he said there is a lot of sludge buildup causing the car to get really hot so i do not know if this mechanic is just taking me for a ride of whats up.

An engine flush uses chemicals to break up sludge that has accumulated inside the engine, it is very hard on gaskets and has been know to cause oil leaks on a vehicle that didn't have any before the flush. So on this old of a vehicle I would not recommend having it done. If you do have a problem with sludge start using a quart of Rislone with every oil change, keep the RPM's down and you will have to change it more often until the oil starts to look cleaner longer then stop the Rislone. If this is a totally stock engine you might consider adding an oil filter system to it, but it is not a requirement. Just make sure you clean the sump screen every other oil change just make sure you it stays open so you don't loose oil pressure and ruin your engine.

Run some Seafoam in the oil for 100 miles, then change the oil.

Change the oil more often - maybe every 1,000 miles until the engine is clean. An oil filter is an excellent idea.

If the oil cooler is all sludged up it might be a good idea to change it out.

or use some discounted synthetic oil and frequent oil changes

Nix the synthetic oil on a old, dirty engine.

synthetic oil has detergents that will clean inside the engine without depriving it of lubrication, and if you can get some for a buck or so a quart it will help

Do not use synthetic in your air cooler, it was not designed to run it and can cause premature seal failure resulting in a bunch of oil leaks. Just stick with conventional oil, you and your engine will be glad you did.
