Can I fit valve stem seals without taking the head off on 1600 sentra 1997


No you can't..
Fitting valve stem seals involves removing the valve springs. This means the valve has to be held in place by a valve spring compressor (bought from almost any spares outlet). The springs are compressed by placing one end of the compressor tool on the valve face and the other end over the spring cap, then squeezing the tool to compress the spring, then removing the split collets that hold the spring in place, removing the spring cap and spring, then eventually you have access to the stem seals.
The head has to be removed to accomplish all this.

Why valves rubber of engine need replace usually??


The valve stem seals (rubbers) need to be replaced when the rubber becomes hard and cracked . This allows the oil to be drawn down into the combustion chamber during the intake cycle and the vacuum is high from the idle situation. It is indicated by a burst of blue smoke from the exhaust when you let it idle (like at lights) and then accelerate away when the lights change. Replacement can be done without the head removal but you will need to find a good mechanic that does this a lot

Blue smoke at low rpms on a 22re toyota


Blue smoke indicates burning oil in the cylinders. Could be worn piston rings, worn valve guides, or bad valve stem seals. An engine compression test may help find it, but a cylinder leak-down test is a more precise way to find where compression is being lost. If compression is good, you just may need to replace the old rubber valve stem seals. A shop could do it without having to remove the cylinder head, using an air compressor hooked up into each cylinder while the valve train is being worked on. The air is used to keep the valves from falling into the cylinder while the seals are replaced. About a 4 hour labor cost, so expensive, but a lot less than a cylinder head removal.

1998 toyota 3.0 valve seal replace


Yes and no.
Depending on how the lifters and rocker arms sit on the valves, you might be able to apply air pressure to the cylinder to keep the valves closed while taking the springs off. If you take the springs off without pressure the valves can fall into the cylinders.
The seals are under the valve springs.

93 sundance 3.0L replace the valve seals


it is more than just the valve seals.the 3.0l engine is notorius for the valve guides slipping down into the valve pocket. there is a fix that involves adding a keeper to prevent them from falling but it requires removing heades and taking them apart. yours may have already have had this done so valve seals may fix it.
yes you can change without removing heads you need to have piston at the very top off stroke if off by a little the piston will be forced down by the air pressure so somehow locking crankshaft from moving would be a good idea.
remove plug from a cyl and fashion or buy a fitting to screw into plug hole that will also hook up to a air hose from a air compressor. the air pressure holds the valve closed then you will meed a valve spring compressor designed for removing the springs with head still installed. can rent them at auto parts stores.remove spring and replace seal. then reassemble and move on to the next
but sometimes the valve opens or piston moves down and the valve falls into the cylinder. you can pull it back up and try again or just take the heads off.
my recomendation is just take the heads off they are fairly easy to remove and instal. then have machine shop cut the grooves in the guides and install keeper clips

Can you replace valve guide seals without taking the head off a ford festive 1994


Yes, you can, but you need to have a special tool that screws into the spark plug hole, so that you can attach an air hose to it to apply pressure inside the cylinder against the back side of the valves to keep them from falling down into the cylinder. The problem is that if the valve seat is not sealing, such as is commonly the case when a valve is burned, then the tool will not help you and you will have to remove the head anyways. Ford makes special tools for removing the valve guides and to install the seals.

I have 94 miata with oil leak in back of the engine looks like it's coming from the right side somewhere


If I can remember,, check valve cover rubber where it seams with camshaft rubber on rear of cylinder head, the 1/2 moon rubber sits in a concave slot in head itself,usually removed, clean and reuse rubbers with a dab of silicone.
