where are the EGR passageways in the intake manifold?

never heard of BG44K but i will look into it.

i've had good results with seafoam, both by adding it to the oil to clean the oil scraper rings and letting it sit in the combustion chamber to clean the chamber out. why are you hesitant about it? i'm not being critical of you, i am legit curious and wonder if there's something i should be aware of.

i have heard of steam cleaning the combustion chamber with water but have been warned that it can go badly if one is not careful. i'm not sure how or why it could go badly but that's what i was told. i don't have a paint gun, is there another way to do it? what about a small spray bottle? would the water droplets still be too large?

i will probably wait to see if the problem persists on future hot days. if it does i will try retarding the timing slightly, and if that doesn't work i'll contemplate the above approaches some more.

thanks!
