seafoam cleaning procedure

[jss]

ok I read a lot about using seafoam to clean out the fuel injection etc.. which vacuum line do you add it in ,where is it located ???

These are easy to get to. As I recall you want to suck it in reasonably fast but you want to avoid a hydraulic lock.

Be very careful with those fittings. At this age, they are very brittle plastic. I use the one to the lower right.

Ah BIG second on that being careful with those old brittle parts.

Cut the tubing off and replace it. It is easier than finding and replacing that part.

I must be lucky, i can pop the left on on and off with no problems. It mys be because I have had it off several times doing thermostats.

I have heard that water instead of seafoam will clean carbon out of the combustion chamber when injested the same way.

safest thing to do is spin the hoses free of the connectors first

Water might work but seems liek Seafoam would be much more effective cuz its a Hardcore cleaner. I'm guessing it has a lot of like mineral spirits like Marvel Mystery Oil does

Ok I separate the tubing at the rubber connector on the left ? How do I get the seafoam in the line I'm a little lost on the procedure , pour it in or what ?

Insert a tube into the connector, long enough to reach the bottom of the Sea Foam can, while engine is running. Be careful of any moving, or hot, parts. As the idle drops, pull the tube out of the liquid, then put it back in when idle rises again. One can manipulate the throttle to keep engine running while tube is in. With older cars, I always run the engine up to operating temperature first, then as the can is drained, let engine die with the last few drops. Allow engine to sit for a few minutes, then fire-it-up WOT, to blow out remaining crud from injection system and cylinders/valves. Do not do this in an enclosed area, (garage), as fumes will overcome you. Black smoke, (carbon, crud), will dissapate as carbon/crud is blown-out. When smoke is gone, job is done. Be careful not to over-rev engine thru process, but don't "puppy" it either, or the crud won't blow out. When finished, take it for a 5-10 minute hyway drive to ensure all crud is evacuated from cat/exhaust.
