I was told i have some bad valve seals which is causing smoke to come out of exhaust. Could someone give me info on how much this will cost and directions on how to do it? Is it too complicated for a novice?

 

I4 or V6 ???

 

v6

 

to do it still on the car u will need a modified spark plug(the threaded part) made into an air chuck..and a fairly decent aircompressor..and a vavle spring tool ment to b used while on the block still..not sure on the specificz of that engine but that is the general procedure for doin valve seals on pretty much ne engine..

 

How many miles on the engine ???

 

about 145,000

 

With that many I'd really pull the heads and have the valve seats reground and do the entire head and replace the seals ...
doing them in the car won't help if you have bad valve seat sealing ...
