Hey guys, big bummer here. i posted some days ago that i was having problems to start the truck and decided to pull out the injection pump, took to repair and picked it up 2 days later. proceeded to install and cranked without the intake manifold just to make sure timing was good and no leaks were present, at this time everything sounded good (serpentine belt was also disconnected so no fluid will be pumped. inside intake) turned off and installed the manifold and all related. started again and a minute later started hearing that clanking noise. For a second i thought it could be a stuck injector but suddenly stopped. Went to check everything and noticed the coolant tank was empty, checked the oil and is full of coolant. so, here is the question for the ones who have done this work already, have you sent the heads to repair or bought new? the questions is because i have heard the early GM engine heads had some kind of not too good alloy and they were/are problematic. also, thinking to send this to a mechanic for the repair, everything is so cramped and uncomfortable to work with that engine. i would have to get a quote and find out what is better.
