Been there done that have extra T-Shirt in extra large...heres the pop......my "RE-DONE" heads with knurled guides along with total valve stem travel that exceeded depth of umbrella seal resulted in the valve guide NEVER being covered and the healthy re-built engine sucking down oil thru the guide. You can bring the piston to TDC pressurize the cylinder with air and compress the valve spring with proper tool if you really want to inspect the umbrella seals. I pulled the heads screamed at the shop that charged me top dollar for average work, had him re-place the guides with new and cut the heads for positive stem seals. Also its worth it to do the cut out valve cover check mentioned above, I had to re-shape the spouts on the deflectors on my 428 and that solved my wet plug thread problem. I will be happy to loan my cut out valve cover to you. OK I will go back to lurking now |
