dead cylinder after replacing headgasket
hey there guys i really need everyones help on this problem as it is my sole vehicle and work is too far away to walk. the engine is an I6. I replaced the head gasket two weekends ago and ever since it has been acting as though I have one dead cylinder. All the plugs have spark as a guy at work showed me a trick to do when the truck is running to pull each wire individually and whichever doesnt make the engine run worse is the dead cylinder in this case its the 3rd cyl.
oddly enough he failed to mention to wear gloves, because the distributor can ark to your finger from 1.5" away. Ow, anywho the truck has the dual exhaust three front cylinders to the left, three rear cylinders to the right. my left exhaust has suction, it beats twice then draw then beats twice, draw. both seem to burn rich, but the right side is smoking alot more than the left. they do connect in the middle through a steel casing which houses my O2 sensor. my oil pressure is extremely high it goes right up to the H. the engine idles good but as soon as it hits 1200 it vibrates. and driving is kinda impossible. now a mechanic said to check vac lines and so on and so on. What do I do? Im under the impression that maybe when I put the pushrods into their spots that the exhaust valve may of have not been put into its spot properly and bent the rod. thats all that I can think of now, please any insight would be extremely appreciatedly
