coolant flow to ISC and IAC

[kthnos]

yes, its the same as the picture on ebay. and its exactly the same as the old EGR i pulled off. my CEL is functional (on at ignition) and always off when engine starts. i am just worried if exhaust gases really reach the EGR on the first place. i had noticed some pinging but it was corrected when i adjusted the dizzy (PO had set the timing to 12 degrees static!). i had adjusted it to 8 degrees and runs much better with no (audible) pinging. cam bolt seems ok (no play/cog to the cam noticed).
