You can try using a torch (heat) to expand the metal-either the head or manifold or an impact wrench or increase leverage (longer handle) substantially. If that tight use only a 6 sided socket for better grip and so you don't round off the head
Its underneath exhaust manifold on driver side . Take loose 2 bolts pull pipe to firewall. some cases exhaust mainfold must be removed.
Bad trans mount, bad u-joints, loose mounting bolts.
Very unlikely. It is most probably a blown head gasket or cracked block.
Intake manifold gasket may be leaking - check for loose bolts or replace fasket.
Once the wiring and the bolts are removed, the starter should be loose enough to pull out and remove. If not, then tap it to "break" it loose - sometimes the starter will "bond" due to dirt, grime or sludge.
Check the mounting bolts on the break pad assembly.they get loose and sometimes come right out.
Check your motor mounts, exhaust heat sheilds, and anything else that could be rubbing metal to metal. Check for loose bolts. Check for loose front end parts.
I have a 1989 Probe and also had a tick, I found that the exhaust manifold bolts were loose. I removed the heat shield and tighten the bolts. NO MORE TICK
It would probably be best to remove the radiator fan and radiator, to give you a little more working room. Then remove the bolts that hold the exhaust manifold to the headpipe. There are several bolts and/or studs with nuts that hold the exhaust manifold to the engine head, remove them, saving one of the center bolts/nuts for last. You may need to remove the AC compressor, but don't disconnect the refrigerant lines if you do; just set the compressor somewhere out of the way. Once all of the bolts and nuts have been removed, just gently work the exhaust manifold loose and pull it off. Clean all surfaces. The gasket between the head and the exhaust manifold will stick in places, causing some inconvenience as you remove it. Don't nick the head as you clean it, that can result in a place for hot exhaust to leak out and will result in eroding away part of the head and you'll end up with an even larger exhaust leak. Find a good technical reference book to get the proper torque settings for the exhaust manifold bolts/nuts. If you over tighten, they will pull out of the head. If you do not tighten enough, they will work loose. Use a NEW doughnut gasket between the header and the head pipe.
No bolts, just twist the bulb assembly counter-clocwise and it should come out. Since the bulb has been there for a while it may be difficult to break loose from the headlight reflector assembly.
I had the same problem with mine. There is a metal piece in side of the exhaust pipe that can break loose and resonate (vibrate) with reving of the engine. The cheap and easy fix is to torch a small hole in the exhaust pipe and then weld the loose metal piece to wall of the exhaust pipe then weld the hole shut. Mines been good since. Please post if this is not the problem.
Retighten or replace the bolts
