BG 109 is only added to the old oil right before you change it. It removes the varnish and breaks down the sludge buildup in the engine where oil is. It also helps to clean the oil rings on the pistons. It basically does the same thing as Kreen. When using 109 you must idle the engine for 10-20 minutes and immediately change the oil and filter.So, I take it that BG 109 can be introduced into part #47472 a little at a time? I wrote BG today about a complete service, who performs it in my area and hopefully I will get a response in a couple of days.
I'll look forward to this. For D.drumz , my understanding is the product you are looking for is BG 206I use sea foam. I haven't seen a need to do BG as sea foam is more readily available to me. I plan to buy a snake camera to really get in there and see what's going on and if it's working.
This is where I put my seafoam in. It's the reference line that goes to the intake manifold after the throttle body. I used about 1/3 of a can (liquid form) and just slowly poured it in while keeping the end of the hose half covered as to keep some vacuum in the line and create a suction that would pull the seafoam in without creating a mess as I poured it. Took me about 5 minutes to pour it in slowly. I always have someone watching the exhaust so when I start to see white wisps of smoke I know I've saturated the engine enough. Then let it sit for about 5 minutes, but you could probably let it sit longer like 15-30. But at some point it's done all the soaking it can and it's time for a smoke show. Start it up and pound the throttle for a mile or two to clean all the deposits out.
This location works well for me, it draws air upstream of the cylinder head where all 4 cylinders can draw from which is critical...
