1: tisking that increases with throttle
2: knocking above 2K rpm
3: loud knocking when no gas is applied, but in gear and driving around (coasting in gear).
4: High pitch squealing every now and then...don't think it is a belt since I just checked those.
Possible problems that I can conjure up with some knowledge of past or present issues...
1: Exhaust header gaskets are too thin or are bad, so knocking from that.
2: Tranny problems (tranny has been bad for a while now)
3: Broken rod in a cylinder.
Is it wise, or possible to unplug a spark plug from a cylinder to see if it is the culprit? No oil is mixing with the antifreeze.
Also, the other day I noticed when trying to put it in gear, the gears in the tranny seemed to still be moving....
You've already checked the oil and coolant, which is good. You should also check your plugs and make sure they are all uniformly colored.
You can diagnose a faulty cylinder by unhooking the sparkplug wires one at a time while the engine is running. Make you don't touch anything but the wire, or you're likely to get a good jolt.
Get a timing light and make sure the timing is within spec.
Make sure you are getting good oil pressure. If one of the rods were broken it would have found it's way through the block or oil pan by now, but if it is a rod knock, you're going to be looking at a fair amount of work.
I don't think it is an exhaust gasket, although that could cause the tapping that you hear.
I am thinking the tapping you are hearing is caused by the valve train's lack of oil pressure. Do you have an oil pressure gauge? The loud knocking could also be caused by this.
Pulling a plug wire to see if the knock stops is not fool proof. Even if that cylender is the problem, pulling the plug may not stop the knocking. However, if it does then you know you have found part of the problem. So I would go ahead and do it. It won't hurt anything if only done for a little bit.
It sounds to me like the problem is with your engine not with your transmission, but I can't be certain without being there.
Haven't tested it yet bobjp. Didn't have any fluid on hand. Getting some tomorrow.
I have a wetline oil gauge. In the morning when it isn't warmed up, it spikes and stays around 60psi. After warmed up, it will idle around 15-20 psi, sometimes dropping lower if the rpms drop too low.
I know for sure, that I can wiggle the clutch foot that sticks out of the tranny, and that it makes a "knocking" sound just by playing with it. (With the engine off.) With the engine on, that thing is knocking, however, I still have knockings coming from the engine as well, on the driver side, towards the front.
