How do you prime the oil pump a 1993 Honda Prelude Si?

A easy way is to either crank the engine over with the starter motor, without the coil being plugged in until oil pressure is obtained.If rebuilding an engine and you want to prime before completion just squirt oil into the oil pickup while the engine is upside down and turn the pump drive to lube the internals. This will help get pressure faster when it comes time to prime with starter motor when engine is in vehicle.

What seal is best to use for a quick fix on a head gasket in a 92 Honda prelude?

none, you want to get it replaced, this is the most critical gasket because it prevents specs of dust and foreign objects(antifreeze) in the places it needs to be. If you use something like silicon you just increase the chances of silicon getting into you're engine and tearing everything to shreds.

When you take the spark plug cap out down where the spatk plug is theres oil and when you take the plug out there is oil down and all over the plug whats the problemits a 1992 Honda prelude with a f22?

Remove the rcoker cover (8 nuts and a little fiddling about), turn it over and you'll find 4 thick rubber o-rings. These perish overtime and allow oil from the head to seep down the spark plug holes. They can be purchased separately from Honda or my advice will be buy a rocker cover seal kit which will include main rocker gasket, spark plug seals, 8 x rocker top washers and 8 closed-head nuts. Well worth the extra cash. Peace!

You didn't specify a model year, so it's difficult to answer this question.

How do you replace the oil pan on a 94 Lincoln Mark 8?

It it a somewhat complicated procedure, as you must lower the subframe to get clearance between the engine and the front subframe to have room to work. Get the car in the air using a lift/jackstands/etc.

Next, remove the long bolts that hold the motor mounts to the subframe (13mm). Use a Hoist or A-frame to securely suspend the engine so that it will not fall out of the engine compartment when you lower the subframe.

You will need a Torx socket (E-18 sized) to unbolt the subframe from the car's body.

You may need to unbolt some front suspension components (Upper control arm to Spindle nut; Air-Spring/Shock combo tobody nuts) to be able to lower the subframe.

Place a jack under the subframe before you remove the bolts; you only need to lower the frame a few inches to have room to work.

Be sure to use a NEW oil pan gasket when it's time to put everything back together. This is not a job one wants to have to do over again because of leaks.

Where is the air filter on a 1988 Honda prelude si 4ws?

Pop the hood. See the intake manifold? Its the big silver thing at the back of the motor. Just to the left of it should be large black ribbed, rubber hose coming out at a 90* angle then shooting down. At the end of that rubber hose is your air filter. It is inside of the canister that is there. Otherwise try www.preludepower.com

93 Honda prelude radiator fans do not come when up to operating temp?

first, check your fuse i believe there is a fuse for that ,second, it could be a bad fan try to test the fan by hooking it up directly to a twelve volt source like the battery and if the fan works then your problem is deeper.

How do you change an alternator belt on a '93 Prelude Si?

well I'm not quite sure on a '93 but on my 86 Si there is a hard as hell little bolt in an arced slotted bracket. if its been on a while you might have to loosen it alot or take it off all together. Once you have done that then simply take the belt off. (first you might have to take off the power steering and AC compressor belt. second as i said if its been on a while you'll have to pry it some to get it to swivel.) After the belt is off put the new belt on and then put the adjustment screw in until just slightly snug(you still want to be able to move it at this point CRUCIAL!. now here is where you need either an extra person with strength and someone to tighten the bolt. get a something you can use to pry the alt. (possibly what you used to pry it loose) till the belt is fairly taught. however be very careful on how you pry at it so as not to bust it. Also over tightening it may harm the pulley which is bad. the proper tension would be when you push on the belt with firm but not hard pressure it will give about a quarter of an inch(after you've tightened the adjustment screw. once you get proper tension go ahead and tighten down the screw as hard as you can use a cheater bar for extra leverage would be a good idea. put the rest of the belt you took off back on (p/s and A/C doesn't work on mine so i left them off) and start the car. if it squeaks its to loose(don't use belt dressing) just loosen the screw and pry it more taught and re tighten screw and try starting again. once you get the whole bit done drive the car around for about 20-40 minutes because the belt will get warmed up and also stretch a little bit. (it took mine about 3 hours to get completely worked in) after that recheck the tension the deflection of the belt should be between 1/4 to 1/3 of an inch with firm pressure as mentioned below. now enjoy a better MPG a better charged battery and a squeak free drive.

NOTE!make sure you have the belt seated in the grooves respectively you don't want the thing fly off at 3k RPM's and getting wrapped around other pulleys and totaling your car.

What is the ignition timing for an 85 Cadillac Eldorado 4.1 liter?

I have an '84 Eldorado, with the same engine. The timing is set after the engine is warmed up, running at 800 RPM or less. You must first disconnect the green connecter behind the distributor near the firewall. The setting is 10 degrees before top dead center (10 DEG BTDC). Although on an older car like this you'll find you get better performance by advancing it a little more. I set mine about 12-13 deg BTDC. Then don't forget to re-connect the green connector.

How do you replace a oil pan on a 1992 Honda Prelude?

Raise and support the front of the car. Remove the crossmember and downpipe. There is a cover for the transmission - remove that too.

Remove all the 10mm bolts around the oil pan. Pull the oil pan off. Replace.

Don't forget to drain the oil first!
