JULY
Let me begin this by saying the mindset of "oh, while I'm in there...!" is a treacherous and expensive path, LOL Well, off comes the head. ![]() I couldn't have the car out of maintenance for too long, but I also wanted to make my time inside the engine worthwhile, so I had a bit of a balancing act doing this, on top of learning to change a head gasket for the first time, heh. So let's take a look: Tops of the pistons definitely look like 200,000 miles. ![]() Chambers #3 and #4 have seen better days, which I'll need to further investigate later down the road. ![]() Exhaust valves have the same story, and intake valves for #3 had debris on it. ![]() ![]() ![]() ![]() With the head disassembled, I had it dropped off at a machine shop for testing, cleaning, and minimal resurface. One thing I've been meaning to do was to refresh all the vaccum lines, and this was the perfect time. ![]() ![]() ![]() ![]() I've always had a suspicion of the IACV's condition because when I get off throttle, the car will bog down, sometimes bad enough where it would stall itself. Lo and behold, it was as dirty as expected and missing 1 bolt of the 4 (head gasket was changed by a random shop many years ago) ![]() Cleaned: ![]() I was going through the lines that run through the lower intake manifold, and found a hose to be "crunchy" inside. It was the line that ran coolant through the throttle body. Nothing came out when I disconnected it, so I just cut it open since I probably couldn't salvage it. ![]() ![]() YUCK. Very likely from the old heater core and just old gunk/rust that was never able to exit the system. Of course, I couldn't stand to reassemble the engine with the pistons in the condition they were in, so I had the engine bay masked up and went to work. ![]() ![]() ![]() Ah, yes. Satisfaction! Also, this happened: ![]() But we'll get into that another time~
