I want to Sea Foam my Loyale. Any tips on the best location for adding it? Can I add it where the PCV valve goes in? That location is most convenient. Will it reach all of the cylinders if I add it there? Is there a better place? Thanks.

might i suggest condensing all your questions into one post.

makes it easier for you to track and to answer all in one.

 

 

ive always taken the brake booster line off with the car running put my thumb over it so the car doesnt die and adding it little by little till it does die, let it sit then let the smoke show begin!

after letting it sit, and you start it up for the smoke show do you just let it idle till it clears up, or do you drive it??

i usually let it idle for the most part while giving it burst of gas, then blast it down the road just to get out that last little bit.

Yeah, the harder you rev it the more gunk is gonna break loose and blow out. Yeah wait till most of the smoke clears up (About 20min) and then just drive it hard a few times down the highway (High rpm shifts)

 

Seafoam is good stuff no doubt about it.

I have never used the Seafoam stuff, when you dump it into the engine do you use most of the can before it dies? Or will a can do 3 to 4 treatments?

on a carbureted engine could you just dump it in the carb?

on a carbureted engine could you just dump it in the carb?

 

Or you could avoid hydrolocking the engine.

 

go for the smallest vacuum line, and have it suck it in through that one, you may need to use a spare hose you have laying around the house, but if you suck too much in too fast you'll grenade the engine.

 

once the can is empty let the car sit for 20 minutes, then start it up and drive hard.

 

 

Do this whole thing on a hot engine, a cold one won't clean up as nice.

What about the oil, should that be changed after the flush run.

Is there any effect on spark plugs also.

thanks

Is the search function broken right now?

You gotta make sure it goes into the middle of the manifold. If it goes in one side, you're probably only cleaning out one bank, and increase the risk of hydrolock.
