Well, if it isnt broke, well you know the rest. As a kid in the shop we were directed to add dextron 3 to the fuel to decarbonize an engine. I have practiced this and my ford 5.8 that just hit 280,000 .. Cant say that was it, but point being it didnt hurt it. They actually make a old school fuel additive called Marvel Mystery Oil, It is Dextron 3 mostly. The oil consumption test you can do, Do a oil change , after 1000 mi. drain it and see that you have what you put in. That is what they are charging you too do. Is it worth it? umm, no

sell it to highest bider

Possibly low on refrigerant. When system is low on freon, it does not build up enough high side pressure to engage the condenser fan . When pressure is high enough. a high side pressure switch kicks on the cond. fan to maintain high side pressure. Have the system evacuated and recharged to proper level. A system dye can be added to check for any possible leaks.

Use a bottle of yellow HEET dry gas / fuel dryer to remove moisture in your fuel tank.

they are located on the back of the heads

next step is a compression test then a leakdown test to eliminate a mechanical problem (burnt valve etc..)

so missfire detected and cylinder 3 missfire detected. check to see injector pulse with "noide light" if ok injector is problem remove fuel rail and injectors look into top of injector for blockage in screen filter in injector if blocked clean out or injector carby places can remove this screen replace it and test injectors and clean or just buy new injectors. make sure to clean out fuel rail and change fuel filter also. if noide light flashes irratic or not at all wiring issue, check for power on one wire with ignition on 12v other is earthed by ecu when opened to inject fuel. other thing that can cause problem on cylinder is tappet clearance "shims" too tight, could do compression test to see if compression is low on cylinder or a cylinder leakage test to see if valves are leaking. broken valve spring. valves do not hit piston on these engines even if cam belt breaks, they are a "free wheeling" engine

can you hear relay clicking in door handle switch assembly when pressing if yes but windows still dont go up or down its probably the electric motor, remove door trim and check for power on one of the electric motor wires when pressing the switch up and then down if power there replace motor, the relays and reverse polarity is done in the switch assembly, if no power at motor and relay switch clicks replace switch assembly

Here's a link on how to replace your oil pan gasket.

Disconnect steering column down by brake pedals and turn wheel with steering disconnected.....if squeak is still there its in the upper steering column bearings...squirt silicon spray down the top tube [below the steering wheel] until it runs out thru the tube lower bearing.P.S dont forget to reconnect the steering!!!
