Hello and welcome to FixYa!

Looks like that you have a worn out piston rings and gasket. I suggest that you have it replaced to prevent more damage to the engine. Once the piston rings and gasket are replaced you'll be good.

Hope this helps and thank you for using FixYa! Have a good one!

FIRST CHECK YOUR OIL LEVEL, IF OK YOU MAY HAVE A FAULTY SENDING UNIT OR BROKE SENDING UNIT WIRE, IF OK, CHECK FOR LOW OIL PREASURE

Does it crank over ? Do you have spark? Need some details partner.

If you suspect that your wires are faulty, you grab a spray bottle and fill it with soapy water, then spray the solution on each wire one at a time. If they are bad you will notice a good arch coming from that wire. Just becareful not become the ground or you may get shocked. Good luck!

The only refrigerant for car A/C systems now available is R134a. Auto parts stores / WalMart sell kits for the do-it-yourselfer. About $40 for the kit with retrofit ports included.

Double check your wires, sounds like you may have crossed one.

Pull the pump and check to see if the baffle in the fuel tank has come loose. Over time sometimes the baffle in the tank comes free and knocks against the pump causing it to short and damaging the pump itself. Unfortunately if that is the problem you will have to replace the tank. There is no way to remove the baffle or re-attach it.

If it has an Automatic transmission the easiest way to to remove the motor from the top with the transmission attached. If it has a manual Transmission you will need to separate the motor from the transmission. Most of the repairs you would have to do to include doing a rebuild can be done with the engine in the vehicle.

Perfect perfect, well they say dont reuse the head bolt,(there toque to yield). Yes loose head bolt ,fails when not at the proper torque and will cause that .and that is the whole problem. Plus you have 120,000 and at a 100,000 its normal for the head bolt to stretch. And they do stretch.

Check your camshaft position sensor,knock sensor,cranck sensor

Can be bad synchronizers or can be the clutch needs adjustment. I would think it is the synchronizers if it does not grind in 1st or 4th.

Try Ebay for good prices

Sorry, but there seems to be something confusing here. With the engine at TDC and the rotor pointing at the #1 position, moving the distributor would achieve nothing more than throwing the timing out. To do ignition timing you heed a timing light and the engine running, then you use the timing marks on the pulley and the front case to set the distributor to the correct number of degrees before TDC as per the manual.

yes but you need a repair manual for details-books are the mechanics tools also--go to parts place or online
