Huge bump, and update.
So, from all the previous posts, I was 90% sure of a cracked head. Over the past two months, I've been saving up for the parts and whatnot to fix her. Eventually, I had bought everything I needed. Contacted Subruise for help, and he offered a new engine that he had sitting in his garage. I figured it might just be easier to swap in a new motor, versus rebuilding my old one. Plus, the new longblock only had 116K miles on it, which is practically new.
Today, he came over and helped install it. Four hours later, I had everything put back together. Subruise said to use RTV on the intake manifold gaskets, but the previous posts said that they were a dry install. I don't have any RTV, so I decided to install the new intake manifold gaskets dry. Also, keep in mind, I'm still using my old intake manifold.
Just came back from adding some coolant in the car. At first, everything was going well. No leaks or anything. Then, I started to notice a wet spot near cylinder #4, which if you remember from previous posts, is the reason why I suspected a cracked head. I started paying close attention over there, and noticed it was coming out near the gasket. I tightened down the bolts even more than they were, and started pouring more coolant into the radiator. I noticed that coolant was still coming from that area.
First thing that went into my mind: the gasket isn't sealing properly. Time to buy RTV. But then I felt the bottom of the intake manifold. The entire bottom of the intake manifold on the driver's side is wet with coolant. Passenger side is dry. So it looks like the coolant is leaking out of the throttle body area, and it's running down the bottom of the intake manifold. I look over there, and notice there is some coolant on the outside of the throttle body intake. Tighten down the bolts, which were surprisingly loose.
Start pouring in more coolant. Same problem. So I decide to pull the spark plug in cylinder #4. Luckily, the spark plug well is empty and dry.
So, what are your opinions? Again, I've got a new block, heads, etc., although my intake manifold is still original to my car. I still don't think my intake manifold is cracked, but I may be wrong. I believe I posted it, but I replaced the throttle body intake gasket (the "toilet bowl" gasket) back when I was originally diagnosing this problem. When I replaced that, there wasn't even an old gasket to replace there. So maybe with the gasket there, it provides enough clearance to let coolant out? The bolt in this picture has coolant on it:
I should note that when I watched the coolant flowing out near the manifold gasket, it was flowing as almost as fast as it was going in the radiator. This leads me to believe that there is a prominent leak, not a hairline crack in the intake manifold. Maybe I'll try removing that toilet bowl gasket to see if it fixes it, but if you guys have any idea, that'd be great.
Okay, went out and removed the "toilet bowl" gasket. Seems to have fixed it. Wasn't leaking like it was. Coolant level is holding steady in the radiator. I'm going to let is sit for a few minutes and monitor any changes.
Is it just me, or is this stupid? WITH a gasket, I leak coolant. WITHOUT a gasket, it works perfectly fine. That just doesn't "click" with me, haha. Oh well, if it works, it works. A previous owner might've messed with it. One of the previous owners disabled the A/C compressor and hill holder, so I wouldn't be surprised if s/he did something with this.
Removing the TBI gasket solved the leak. Coolant level is staying steady. Oil is full on the dipstick and the engine is ready to go.
Plug in the battery, turn the key, click click click. Back to the exact same problem as before.... It cranks for a split second, then just clicks. Went to O'Reilly to have them charge my battery, but they were closed. So I bought an automatic charger from Fred Meyer and it's currently charging my battery. I charged it for two hours, tested it, and didn't seem to help much. Gonna try it tomorrow, after it's been sitting overnight on the charger.
