Combustion chamber cleaner question

[TheDoughboy]

I got a can of JB chamber cleaner free that we had laying around the parts department for quite awhile. We had MOC but now have BG products. I can use the vacuum injection tool to apply it. What port on the intake on a 4V would distribute the liquid Evenly between Both banks? I was thinking about adding 5-6 oz's quickly until the motor floods and dies then let it sit 30 mins.

Then rack the car up on the lift (just a foot) and add the rest of the cleaner with the engine running and in Gear under a load. Once I hit 4k rpm's I'll let the cleaner flow in to clean the Open IMRC's. Once all done I'd take it on the road for a hard run.

Any ideas on this? Good/bad?

Thanks,

Ron

Never heard of that stuff. I just use Chevron Techron fuel system cleaner occasionally.

I ran some BG 44K in my tank through the injectors with great results. The JB is for the intake track and hopefully the IMRC's.

I have used the seafoam method of cleaning IMRCs with good results. Just suck a can in through the PCV hose on the intake, shut the engine off and let it sit for 30 min. Start it up and rev it to 2800 for 30-40 seconds. It will create a heck of a smoke show so your neighbors may get mad. It is REALLY bad. Then, drive the car around making some WOT blasts to clear things up. It will still smoke bad for a few miles of driving but it will clear up and you will "feel" it breathing easier.

Nothing will actually clean the IMRCs and secondary intake valves with the exception of manual cleaning. Combustion chambers are a different story.

Mine must have been exceptionally clean over the years because at 75k miles, I had to have new heads put on the car. I ran the seafoam through about 100 miles before my head problem surfaced because I didn't want to mess with disassembly at the time. My IMRCs were amazingly clean when they came out. I should have taken a picture. Granted, I didn't know what they looked like before, but ....

If you've deleted the EGR and replaced the PCV with valve cover breathers or placed a catch can setup inline with the PCV valve then you will not have this problem.

Adding through the PCV port, will the fluid distribute evenly on both heads or is there another port to use?

PCV port is in the hat so it will distribute as evenly as possible

Cool thanks!
