Howdy, It is not running on cylinder 2 and 8, It does run quite smooth on the other six. I got spark and the intake lifters seems to open up and the intake runners are free. Could the timing be wrong, any sugestions?
Bad plugs Bad plug wires Carbon tracks in the cap, or bad cap vacuum leak Toasted valve - do a compression check on 2 & 8 Should be fairly straightforward to "nail" down. Mark
Mark, I forgott to mention that the compresion is good, 188 and 190 I changed plugs and leads, cap is new. Now I took the Intake of and I found that the intake gasket was not installed properly and the bolts were not tight, so it might be as you suggest a vacum leak. What vacum should I normally get? Regards Dag
Was it running well before? You might pull the intake and valley pan and check for broken exhaust side pushrods. I had a similar problem recently. Dan
Look at the bright side. At least now the Ford's will stand a chance and you'll have a killer come back to their lame excuses for losing "...yeah? Well I was only running on six cylinders...what's your excuse?" :grin:
I looked at the pushrods and they seems to be ok, I bought the car a 63 Riviera from the USA and someone has been working on the engine, it was not running when I got it. Is it possible to get the camshaft wrong ore something else inside the engine so it only runs on 6 cylinders??? Dag,
You might pull the driver's side valve cover and slowly turn the crank with a wrench and watch the pushrods and valves on 2 and 8. Pull the passenger side cover if it's not a royal pain(a/c car) and the dist. cap to make sure that the distributor is set right to fire on one when one is on the compression stroke. Also, I guess I should add: make sure that you wired the front passenger cylinder as number one.
vacuum Put a vacuum gauge on a manifold fitting. You should be pulling about 20 inches of vacuum. Check your firing order as well and insure your valve lash is correct. The valves/rockers should be moving, if not, you may have some flat cam lobes. Hope this helps, Doug :bglasses:
