Overheating problem...eek! AND, oil prob?
Problem #1 (for today):
Ok, recently in my '88 Firebird, I was driving it back and forth on a small part of my road. Anyway, after about 3 or 4 miles, sometimes mashingthe gas to the floor, sometimes just going and testing breaks, steering etc, the temp was through the roof! So I killed the engine, and coasted back home (yay, all down hill, lucky me!), spewing coolant all over the road. Anyway, when we get back into the garage, and let it cool down a long couple of hours, we firied it up again, and noticed that the radiator stayed completly full after we refilled it (only it too, nothing else), and never sucked the fluid down. After about 15 minutes of tinkering around just pulling hoses and checking them, making sure the pupmp was spinning etc, we refire it, and boom! the fluid gets sucked down like there's no tomorrow, but we never found a clogged hose or anything wrong via visual inspection, we didn't even change anything! So we kept up just by spraying water into the radiator. She still ran a bit hot, we drove it back and forth once, a total of about 3/4 mile, and the temp was reading about 200. Now the fan kicks on and everything, but I was just wondering why the coolant was never sucked down, and if it's something majorly wrong with my engine that it's overheating like that? Lately we ripped the engine off, and today I pull the pump to make sure it's not messed up internally, though I think it should be alright since it did eventually suck down the fluid. I was thinking, do you have to prime the pump in some way after draining it? We had it empty when we pulled the engine the first time, and just filled it and that's when I started driving. Could it have just been like vacum lock? Any other suggestions?
Problem #2:
Ok, again, when I was driving around, at an idle I had ZERO oil pressure. I didn't notice this until later, so NO FLAMMING
. When I was driving around though, I'd notice the pressure gague moving around...and then like I said, at idle, nothing. What could this be? We pulled the pump off and manually turned it in a bucket of old oil we have, and it squirted the oil out just fine? I know it's not the sensor or anything, cos we now have something wrong with the car in the top end, sounds like a nice, like, clunk, almost from the cam to me, and I'm willing to bet it's cos of low/no oil. Any one got any info that can tell me what I broke now?
Thanks guys
