How do you change a valve cover gasket on a 1994 Mazda 929?

First of all, it'll take most of the day to do. Start by taking all the attachments to the plenum on both sides of the engine. Remember where everything was attached. There is a fuel line on the rear of the plenum on the passenger side that is bolted to the plenum. Then unscrew the bolts on top of the plenum and lift the plenum up from the engine. There are two more vacuum hoses that are in the bottom rear of the plenum that needs to be disconnected before the plenum can be completely removed from the engine. They will be hard to reconnect. The main thing is to remember where all the vac hoses goes and where the wire harnesses are attached. Remember the firing order of the spark plug wires. Don't buy the gaskets from the dealer.....too expensive. Try Pep Boys or Advanced Auto. They may have to order them, but they'll be in the store the next day. You will need the complete valve cover gasket kit with the goumets for the screws, and a plenum gasket. Once you place the gaskets on and reassemble the parts, make sure you torque the valve covers and plenum bolts by the manufacturer's specifications. It's a time consuming job. I did mine in about 8 to 9 hours. You may want consider purchasing the parts and have a garage put them on for you. It's not like in the old days where it was easy to get to the valve covers. Good luck. The valve cover gasket kit was $59.00 at Pep Boys and the Plenum gasket was $6.00 at Advance Auto. Most places want over $100.00 for the valve cover gaskets. The dealer wanted $139.00 for the $6.00 gasket that I got from Advanced Auto.


How to change heater hose 96 Isuzu Rodeo?

Changing the heater hose hidden between the engine and the firewall under the plenum on a 96 isuzu rodeo. Best option since there is limited access is to remove the plenum. Take all the bolts out of plenum. Remove wire harness to free plenum up enough to remove. Detach from air intake. Then you'll be able to get at that hose. When putting it back on you'll need a new plenum gasket. Hose cost around $10 and gasket is like $6. Garage will probably charge you $300+

It is located under the plenum. It is easy to change. Make sure you get a new plenum gasket. It took me about a half hour, maybe a little longer.


After beginning to produce white smoke from the exhaust a 98 Bonneville dies and would not start again what could be causing this?

White smoke is coolant in the cylinders. Died and won't restart cause the spark plugs are shorted with coolant. If you keep trying to start it without fixing it you could bend a rod! Most likely it is a failed intake manifold gasket or intake plenum gasket or the intake plenum itself. Don't drive the car cause if it is the plenum leaking coolant into the engine it can fill a cylinder with coolant and do major damage when you try to start it. No way to know for sure which of the three it is without pulling the plenum. If you're pulling that you might as well change the intake manifold gasket too. Could be a bad head gasket
