Sometimes if you are lucky you can tighten the covers and they will seal. Easy does it with a 1/4 drive ratchet and a small extension. You will need a small wrench to get the bolts with mounting posts on them for the wires. You will see what I mean when you do it.

I would start in the middle and go up one position and back one position until they are all tight. The other easy way is to take it to a shop. Myself, I pay people to put exhaust parts on my own cars because I hate exhaust work.

You will know if your covers still leak after you tighten them. All the screws will have to be fished back into position and a gasket replaced if you take the covers off yourself. But there is no rule making you do both in 1 day or 1 weekend. You can use ATV and make your own gasket too. Good Luck on what you decide.

My 91 honda prelude is leeking oil and its smokes when hot but cant figure out where its leeking from


easiest way is to get the dye and poor it into your engine. Then with the dye light you will be able to track the source. On those years the most likely spot was the intake manifold gasket and valve cover gasket. You also could have a blown head gasket that only blew on a oil intake side, doesnt mean that you would over heat

Signs of a bad valve cover gasket


My first question would be, what was the original trouble code that directed the mechanic to replace the sensors ? You seldom need more than one O2 sensor at a time. Its possible the exhaust manifold is leaking and that might cause a problem that would turn on the warning light. Or it could be something else.
A valve cover gasket will leak oil if it fails. No check engine light.

Valve body leak 2002 dodge stratus


A vertical cover...I had to ponder that a bit. Still not sure. The valve cover sits flat on top of the cylinder head, with a gasket between them. The cylinder head is where your spark plugs are threaded in. The valve cover rests on top of the cylinder head. It's about 14-18 inches long and about 4 inches high, kind of rounded over so the valves and valve train will fit underneath. A gasket leaking motor oil is very common there, as a lot of oil is directed there and then splashed around to lubricate the valve train. The oil is supposed to drain through engine passages on down to the oil sump- the bottom of engine where oil is kept in the oil pan.

So if you have an oil leak, and it turns out it is the valve cover that is leaking, it's an easy fix-one of the easiest gasket replacements there is.

Hi i have a 1994 dodge caravan it is leaking oil can this be fix im worry that we would have to save money for a van for my kids thanks


The Chrysler minivan products all had leaking problems. I have had 5 or 6 different Dodge or Plymouth minivans from 88 to 99. How bad is it. The most common thing is Valve cover leaks. Front and rear seals in the engine leak as well as the oil pan gasket. If its leaking a little bit at a time open the hood and look at the front and rear of the engine. Do you see grease and oil that has gone down the sides of the engine? Do you see a lot of grease on the engine with some clean streaks going through it. You may be able to see where its leaking from. If you know someone that knows what their doing have them change the leaky gasket/s. If not you can probably have it repaired for less than buying another van unless other things are seriously wrong with the van.
Hope this helps... Dale

Leaking oil


Your car has several different types of oils or fluids (motor oil, transmission oil, power steering fluid/oil, brake fluid, and differential oil - if applicable). . Before you can determine how to fix your problem, you need to determine exactly what you problem is, meaning you need to figure out what fluid is leaking.

Good Luck!

How to fix a front leaky oil seal in a 1995 Toyota Camry LE


Three seals to check. easiest is the valve cover seal. Number and remove the 4 wires going into your spark plugs. remove 4 nuts holding the cover and replace seal.
Next easiest is the distributor O-ring. Remove air filter assembly remove the distributor cap, then the distributor. With the valve cover still off, loosen the 2 bolts that clamp the distributor down. Remove the 2 terminal leads going into the distributor (4 wire terminal/2 wire terminal) Mark the case of the distributor and the case of the head with one line so you can line it back up on reinstallation. remove the 3 bolts holding the distributor down. Replace O-ring. replace distributor, align, tighten the 2 bolts, then tighten the 3 bolts. replace terminal wiring and cap. replace air filter assembly. Replace valve cover with new gasket. Place spark plug wires back into their proper places. The last one is the oil pan gasket. Drain all oil and remove all blots holding the pan. drop the pan and replace the gasket. Put it all back into place. Do not over tighten the pan bolts as this will cause the gasket to deform, making it leak again.

2002 Passat, 30 valve V6 has oil leaking on exhaust manifold. VW dealer says its the cam adjuster seals. It looks to me like its just the valve cover gaskets but I can't get an engine schematic to see the...


I have a 2000 Passat V6. They told me that same thing. To replace the gaskets is easy. You just remove the covers and the air filter box and unscrew the 6 bolts holding the valve cover on it and there you go. You want to clean around the gasket service and add a little bit of sealant to the edges. Replace the old gaskets and put everything back together, be careful not to overtighten the bolts, can flatten out the gasket and cause oil leak again. On the right side of the engine, you have to remove the coolant box to get to it. Same procedure....

Oil leak


If by head covers you mean valve covers this is an easy fix just install a new set of valve cover gaskets, as this is a fairly common problem ( valve cover gaskets ). Just unbolt the valve covers and remove them then scrape off the old gasket and install the new ones and bolt the covers back on. This is a pretty easy job and the gaskets are less than $ 25.00. If it is the oil pan gasket you will needto drain the oil and unbolt the oil pan and remove it then clean off the old gasket and install the new one.

Leaking oil bad


If you're certain it isn't your oil filter, then it can only be three other things. The first (and easiest) thing to check is a small diamond-shaped plate on the side of the block, under the intake manifold, towards the alternator. It has a bolt and a stud in it. Verify that both of those are tight. If they are tight, check the four bolts that secure the "push rod cover" to the side of the engine. The push rod cover runs the length of the engine and is located directly under the intake manifold. This was the culprit of my oil leak, and I imagine it will be yours also. However, if you find that those bolts are tight and no oil can be found leaking from that area, check your valve cover. The Fiero valve covers were stamped from very pliable steel and it is difficult, at best, to get them to seal correctly. Problems usually occur when people torque the bolts too tight and bend the valve cover. I recommend a product called "Indianhead" gasket shellac. Remove the valve cover and ensure all gasket surfaces are clean. Ensure the valve cover's gasket mating surface is straight - straighten with a hammer and block of wood if needed. Follow the directions on the bottle to the letter, making sure to coat your valve cover gasket surface, both sides of your gasket, and the gasket surface on the head.
